Top Shopify Alternatives in 2026: TCO, Features & Migration

Top Shopify Alternatives in 2026: TCO, Features & Migration

The best Shopify alternative in 2026 depends on what's actually failing: B2B pricing, multi-store control, app sprawl, variant-heavy catalog limits, or the need to own your data and code. BigCommerce is the closest SaaS-to-SaaS swap with the least friction. WooCommerce gives you full code ownership at the cost of becoming your own sysadmin. Adobe Commerce is enterprise-only territory. Squarespace and Wix suit simpler, content-led commerce. MedusaJS is the developer-first open-source option for teams building composable architectures — systems where each commerce capability (cart, checkout, promotions, catalog) is a discrete, independently deployable service rather than a monolithic application.

This guide compares each alternative using verified 2026 pricing, real migration constraints, and total cost of ownership — not feature checklists copied from marketing pages. Every platform has trade-offs the sales pages won't mention.

Why Merchants Leave Shopify in 2026

Shopify powers approximately 29% of all U.S. ecommerce stores (Statista, 2025). It's the default. But defaults don't fit everyone forever.

The most common pain points driving migration requests:

• Rising effective costs. Shopify Grow (formerly Basic) is $39/month, but real stores spend $200–$500/month once you add paid apps, a premium theme, and the 2% third-party gateway surcharge if you're not on Shopify Payments. Online transactions via Shopify Payments on the Grow plan cost 2.9% + $0.30 per transaction.
• App dependency. Features that BigCommerce or WooCommerce include natively — product filtering, abandoned cart recovery on lower tiers, real-time shipping rates — require paid apps on Shopify, each adding monthly cost and page-load weight.
• Customization ceilings. Liquid theming is powerful but constrained. Checkout customization requires Shopify Plus ($2,300+/month). The deprecation of checkout.liquid in favor of Checkout Extensibility has forced teams to rearchitect checkout flows, often requiring dedicated developer cycles that don't appear in any platform comparison.
• Data portability gaps. Shopify lets you export products, customers, orders, and discount codes via CSV. What you can't export: analytics history, abandoned cart sequences, customer journey data, or metafields in bulk without a custom app. That data disappears when you leave.
• API rate limits. Shopify's GraphQL Admin API uses cost-based rate limiting calculated by query complexity. Each store gets a bucket of 2,000 query points that restores at 100 points/second — a meaningful constraint for stores running heavy ERP syncs or custom middleware built on polling.

If none of these constraints hurt you, don't move just to save a small monthly plan difference. Replatforming is justified when the target platform removes recurring operational pain. The decision should be grounded in your actual cost of constraint — developer hours spent working around limits, revenue lost to checkout conversion problems, or GMV-tier fees — not a pricing page screenshot comparison.

Platform-by-Platform Comparison

BigCommerce — Best SaaS Replacement for B2B and Multi-Store

BigCommerce is the most direct SaaS competitor to Shopify and the closest like-for-like replacement for merchants that want managed hosting but less app dependence around B2B, multi-storefront, and ERP integrations.

2026 pricing (post-June 1, 2026 rebrand):

Why consider it: More features ship in the core product than on Shopify. Native multi-channel selling (Amazon, eBay, social), real-time carrier shipping, product filtering, and unlimited staff accounts on every plan. No transaction fees when using an embedded payment provider.

BigCommerce also offers native multi-storefront capabilities — run multiple regional stores or distinct brands from a single backend and unified database. Shopify requires Plus-tier pricing ($2,300+/month) and separate store instances to achieve this, which fractures your data architecture. On self-serve tiers, BigCommerce's multi-storefront is an add-on with limits of 3, 5, and 8 storefronts on Core, Growth, and Scale respectively.

BigCommerce's Catalog API (v3) uses a more flexible option and modifier structure than Shopify's flat variant model. Product options are treated as distinct modifier rules with shared option sets, making it a natural fit for high-SKU catalogs in automotive, apparel, and hardware.

The catch: BigCommerce dropped its GMV caps significantly on June 1, 2026. Core's annual cap fell from $50,000 to $30,000, and Growth dropped from $180,000 to $100,000. A merchant doing $150,000 GMV annually who was on the old Plus plan ($79/month) is now forced onto Scale at $299/month — a subscription increase of nearly 4x. BigCommerce also introduced an Open Payment Provider Fee for merchants not using their embedded gateway list: 2.0% on Core, 1.0% on Growth, 0.6% on Scale. This materially narrows the "no transaction fee" pitch that distinguished BigCommerce from Shopify.

The net effect: for merchants between $100,000 and $400,000 GMV using a non-embedded payment gateway, BigCommerce's effective Year 1 cost is now competitive with — not clearly cheaper than — Shopify's comparable tiers.

Migration from Shopify: Products, customers, and orders transfer via CSV or API. BigCommerce's migration tooling can handle up to 500,000 records and supports historical order creation via the Orders API (use M-MIG in the external_source field to flag imported orders as migrated records). BigCommerce documents delta migration within two weeks of go-live to keep the new store current without a full catalog reload.

URL structures differ — Shopify uses /products/slug and /collections/handle while BigCommerce defaults to /product-name/ — so budget for a full 301 redirect map before cutover. Theme rebuild is required: Shopify Liquid themes do not run on BigCommerce's Stencil framework.

API rate limits: BigCommerce's REST API allows 20,000 requests/hour on Core and Growth, and 60,000/hour on Scale. If you're sizing a high-volume integration — say, an inventory sync that polls every 60 seconds across 10,000 SKUs — confirm that your plan's quota supports your sync cadence before committing to an architecture that assumes near-real-time throughput.

WooCommerce — Best for Full Data Ownership

WooCommerce is a free, open-source PHP plugin that turns any WordPress site into a store. You own the code, the database, and every customer record. It's the largest ecommerce platform by install count globally and is the structural opposite of Shopify's closed-ecosystem SaaS model.

2026 TCO reality:

The plugin is free. Costs shift to hosting ($10–$250/month depending on traffic tier and whether you use shared vs. managed hosting like Kinsta or Cloudways), premium extensions for payment gateways, subscriptions, or shipping ($50–$300/year each), and — the line item most people underestimate — developer time for updates, security patches, and plugin conflict resolution. Budget $600–$4,800/year for professional maintenance if you're not handling it in-house.

Why consider it: Zero platform transaction fees beyond your payment processor's cut. Full database access. Unlimited products and variants with no GMV-based forced upgrades. Absolute freedom over checkout logic, payment gateways (without penalty fees), and backend integrations. The WordPress plugin ecosystem exceeds 60,000 extensions. WooCommerce on managed hosting with Redis object caching, a CDN, and query-level database optimization handles $10M+ GMV without platform-imposed scaling limits.

HPOS: the critical 2026 infrastructure change. WooCommerce has fully standardized High-Performance Order Storage (HPOS) as of 2026. Previously, WooCommerce stored orders as WordPress custom post types in the wp_postmeta table — a key-value schema not designed for relational order data. At scale, this caused severe database bloat and slow checkout and reporting queries. HPOS migrates order storage into dedicated, properly indexed relational tables (wc_orders, wc_order_addresses, wc_order_operational_data), dramatically improving query performance for stores with large order histories.

HPOS has been enabled by default for new installs since WooCommerce 8.2. However, the February 2026 WooCommerce 10.7 release disabled sync-on-read between legacy post tables and new HPOS tables by default. If you have custom code or older plugins that write directly to wp_postmeta for order data, those writes will no longer be reflected in the HPOS tables automatically. Run a compatibility audit before enabling HPOS on an existing store: WooCommerce's system status screen flags incompatible extensions. Stores that attempt HPOS migration with incompatible plugins can experience order data inconsistencies that are difficult to reverse cleanly.

The catch: You are the sysadmin. WordPress core updates, WooCommerce updates, plugin conflicts, SSL, backups, and PCI compliance are your responsibility. The dependency chain is deep: a WooCommerce core update can conflict with a payment gateway plugin, which conflicts with a checkout customization plugin, which breaks your store on a Saturday during a promotional email send. To run WooCommerce at scale, you need enterprise-grade managed hosting (Kinsta, WP Engine, or a custom AWS cluster), which shifts the cost from software licensing to DevOps — sometimes exceeding what a Shopify Plus subscription would have cost.

Migration from Shopify: Shopify's CSV exports map cleanly to WooCommerce's import format for products and customers. For catalogs exceeding 10,000 SKUs, use the WooCommerce REST API or a tool like Cart2Cart rather than WooCommerce's native CSV importer.

Key migration failure points:

• Customer passwords never migrate. Shopify hashes passwords with a proprietary algorithm that WooCommerce cannot decrypt. Plan a reactivation email campaign before launch — a well-timed "Claim your account" sequence targeting your active customer segment (those who purchased in the last 12 months) typically recovers 40–60% of accounts within 30 days.
• URL structure mismatch. Shopify enforces /products/handle and /collections/handle routing. WooCommerce uses configurable permalink structures (e.g., /shop/category/product-name). Generate a precise 1:1 301 redirect map and implement it in .htaccess or your Nginx config before DNS cutover. Missing this step creates thousands of 404 errors and can eliminate months of accumulated link equity overnight.
• Order history imports are reference-only. Imported historical orders won't trigger WooCommerce's native order hooks, workflows, or reporting aggregations.
• HPOS compatibility. Run a full extension compatibility audit against HPOS before cutover. Incompatible extensions discovered post-launch create operational disruptions that the HPOS rollback path doesn't cleanly solve.

Adobe Commerce (Magento) — Enterprise Only

Adobe Commerce is the heavy-duty option for massive catalogs, complex B2B hierarchies, and deep ERP integrations. Available as open-source (Magento Open Source, free but self-hosted), paid on-premise (from approximately $22,000/year), or fully hosted cloud (from approximately $40,000/year). In 2026, Adobe is actively transitioning toward a cloud-first SaaS model called Adobe Commerce as a Cloud Service (ACCS).

Why consider it: Native B2B features unavailable in any other platform at this depth: company accounts with defined buyer hierarchies, shared catalogs with customer-segment-specific pricing, quick order by SKU, requisition lists, and negotiable quotes with approval workflows. Multi-brand, multi-store architecture managed from a single admin. The GraphQL API is extensive and purpose-built for large-scale headless implementations. Adobe notes that assigning product prices directly — rather than through shared catalog price rules — is the recommended pattern for large B2B deployments because price indexing at the catalog level becomes a bottleneck above approximately 100,000 SKU-tier combinations.

Powers brands including Coca-Cola, Ford, and Nestlé.

The catch: Adobe Commerce is not a Shopify replacement for the vast majority of merchants. The platform targets businesses with $5M+ annual revenue and dedicated technical teams. Magento Open Source is nominally free, but a realistic production build costs $25,000–$300,000, and ongoing maintenance runs $10,000–$50,000+/year in agency or internal developer costs. Live store counts have declined from a peak of approximately 162,000 to roughly 112,000 (StoreLeads, Q1 2026) as mid-market merchants migrate to lighter platforms that don't require a quarterly upgrade project. Implementation timelines run 4–8 months. Major version upgrades frequently break custom extensions, requiring retesting and remediation across the entire extension stack. Don't start here unless you've genuinely outgrown SaaS and have a dedicated platform engineering function.

Migration from Shopify: Adobe's native import tools support products, advanced pricing rules, customers, customer addresses, and product images. Multi-location inventory can be mapped by source using Adobe's Inventory Management module. Adobe's import documentation does not list orders as a natively supported CSV import entity — historical order migration is a custom or third-party workstream, typically involving a data engineering engagement of 2–6 weeks depending on order volume. Mapping Shopify's flat customer data into Adobe's hierarchical company account structures requires a full data model redesign, not a field mapping exercise.

MedusaJS — Developer-First Composable Commerce

For engineering teams that want open-source flexibility but reject the monolithic architecture of PHP/WordPress, MedusaJS is the leading composable alternative. It's an open-source, headless commerce engine built on Node.js and PostgreSQL, released under the MIT license.

What composable commerce means in practice: Medusa provides a modular backend API for discrete commerce functions — cart, checkout, product management, promotions, tax calculation — while remaining entirely agnostic about your frontend and presentation layer. Each module exposes a typed API and can be replaced independently. You can swap the default Stripe payment module for a custom payment provider without touching the cart or order management logic. This is the architectural contrast with monoliths like WooCommerce or Magento, where payment, catalog, and checkout logic are tightly coupled in shared codebases.

Why consider it: Medusa handles multi-region pricing, multi-currency, and localized tax rules without artificial API rate limits or forced payment gateways. No per-transaction platform fees. Because it's MIT-licensed open source, you can fork, modify, and self-host without license negotiations. Pair it with a Next.js storefront, integrate it into an existing mobile app, or use it to power commerce within a separate SaaS product. Medusa 2.0 (released late 2024) introduced a fully modular architecture and first-party support for workflows — long-running, resumable business processes (like order fulfillment pipelines) that are durable across server restarts.

The catch: There is no managed app store. If you need an integration with a specific ERP, niche marketing tool, or 3PL, your engineering team writes and maintains the middleware. There is no hosted version — you deploy and operate the Node.js backend yourself (or on a managed platform like Railway or Render). TCO shifts heavily toward internal developer salaries; a realistic Medusa implementation for a production store requires 2–4 weeks of backend engineering and a separate frontend build. This is not for non-technical operators or stores without an in-house engineering function.

Migration from Shopify: Moving to Medusa requires a complete frontend rebuild — you cannot port a Shopify Liquid theme or any Shopify-specific app logic. The migration involves extracting Shopify data via the Admin API, structuring it into relational PostgreSQL tables aligned to Medusa's schema, and building a custom React/Next.js storefront. Medusa's data model uses product variants differently from Shopify — options are typed entities with values, not string fields — so catalog transformation requires deliberate schema mapping, not a direct import.

Squarespace — Best for Design-First Brands

Squarespace is an all-in-one hosted website builder with integrated ecommerce, built around award-winning templates and a no-code visual editor.

2026 pricing (annual billing):

Payment processing is locked to Stripe at 2.9% + $0.30 regardless of plan or sales volume. There is no mechanism to negotiate processor rates on Squarespace — a store doing $2M GMV pays the same per-transaction rate as one doing $50K.

Why consider it: If your brand identity is your primary competitive advantage — DTC fashion, artisan goods, photography, specialty food — Squarespace templates deliver the best out-of-the-box design quality in this comparison. No code required. Commerce features available on every paid plan. Squarespace's SEO tooling and blogging infrastructure are genuinely strong for content-led brands.

The catch and hard limits: Product variant limits are tight: up to 6 options and 250 variant combinations per product. Squarespace imports from Shopify cap at 100 variants per product — any product exceeding that limit requires manual reconstruction. There is no native multi-channel selling to Amazon or eBay, no B2B features, no account-based pricing, and no advanced shipping rule engine. The app ecosystem is a fraction of Shopify's. Automated sales tax is unavailable on lower plans. If you need dynamic pricing, a large catalog, or marketplace integrations, Squarespace will impose structural limits within the first year.

Migration from Shopify: Squarespace accepts Shopify product CSVs directly for titles, descriptions, prices, and images. It does not handle customer accounts, order history, complex multi-option variants, or discount codes through any native import path. For products with more than 100 variant combinations, manual reconstruction is required. This migration is functionally a "start fresh" exercise for all operational data. URL redirect mapping is fully manual with no automated tooling provided.

Wix — Best for Small Catalogs and Speed-to-Launch

Wix is a drag-and-drop hosted website builder with ecommerce capabilities on its Core plan and above.

2026 pricing (annual billing):

Why consider it: Zero platform transaction fees on all ecommerce plans. Fastest time-to-launch for non-technical merchants. Wix Stores supports up to 50,000 products, 6 options per product, 100 choices per option, and 1,000 variant combinations per product. Wix's drag-and-drop editor requires no technical knowledge to produce a functional, mobile-responsive storefront.

Hard limits and disqualifying conditions: Once you build on Wix, your site structure does not export — there is no mechanism to migrate a Wix site to another hosting provider with its structure intact. Multi-channel integration (Amazon, eBay) is limited compared to Shopify. Automated sales tax calculation is capped at 100 transactions/month on the Business plan. If your catalog exceeds 1,000 variant combinations per product, or if you need negotiated payment rates, real-time multi-warehouse inventory, or B2B account management, Wix is not the right platform — these constraints are architectural, not addressable through add-ons.

Migration from Shopify: Shopify-to-Wix requires CSV product export, manual reimport, and a full theme rebuild in Wix's editor. Customer accounts and order history don't transfer through any native tool. Official migration documentation points to Cart2Cart or manual CSV transfer as the only supported paths.

Total Cost of Ownership: Where the Bill Really Shows Up

The base subscription fee is a decoy. Real TCO includes transaction fees, app ecosystem costs, hosting, migration labor, and ongoing maintenance.

Year-1 TCO =
  subscription or license fee
+ payment processing fees (% of GMV)
+ platform transaction surcharge (if applicable)
+ apps or extensions
+ theme or frontend build cost
+ migration labor (data engineering + QA)
+ custom integrations (ERP, 3PL, marketing stack)
+ ongoing admin and maintenance

Methodology for the table below: Assumptions are a merchant doing $500,000 annual GMV with 500 SKUs, using Stripe or equivalent as payment processor, requiring 3–5 integrations (email, helpdesk, reviews), and needing a professionally designed theme. Excludes marketing spend, staff salaries, and bespoke custom development beyond standard integration work.

The hidden cost that doesn't appear in any table: Shopify's app ecosystem is both its strength and its largest concealed expense. Features that are native in BigCommerce or WooCommerce — advanced product filtering, custom fields, complex bundle logic, tiered pricing — often require multiple $49–$149/month apps on Shopify. Each app adds to your monthly bill, introduces a third-party dependency, and adds JavaScript weight to your storefront that degrades Core Web Vitals and checkout conversion.

What Actually Migrates From Shopify (And What Doesn't)

Regardless of destination platform, certain Shopify data exports cleanly and certain data does not. This gap between expectation and reality is the most common source of migration budget overruns.

Exports cleanly via CSV or API:

• Products: title, description, price, images, variants, SKUs, weight, barcode
• Customers: name, email, shipping addresses, tags, customer notes
• Orders: line items, totals, fulfillment status (as historical reference records)
• Discount codes: fixed amount and percentage codes
• Basic financial summary reports

Does not export through any standard path:

• Customer passwords (Shopify's hashing algorithm is proprietary; passwords cannot be decrypted)
• Analytics and conversion history (lost permanently on platform exit)
• Abandoned cart sequences and their associated contact data
• Customer browsing and session behavior
• Metafields in bulk (requires custom extraction via the Admin API's metafields.json endpoints)
• Shopify Flow automation logic (must be rebuilt from scratch in the target platform's automation tooling)
• Shopify Scripts logic (Shopify announced Scripts will sunset August 28, 2026; any store still using Scripts must migrate to Checkout Extensibility before that date regardless of replatforming plans)
• App-specific data: review content (Yotpo, Okendo, Stamped), loyalty point balances, subscription billing records, and gift card redemption history are stored in the app vendor's database, not Shopify's — extraction requires direct API access to each vendor

Internal IDs break on every migration: Shopify generates proprietary numeric IDs for products, variants, orders, and customers. None of these IDs carry over to any target platform. The only stable cross-system identifier is the SKU. Before signing off on a migration plan, verify that every downstream system — WMS, ERP, 3PL, marketplace feeds, Google Shopping catalog — references products by SKU rather than by Shopify's internal IDs. Stores that discover this dependency mid-migration face multi-week delays while ERP integration teams remap their data models.

Cross-platform variant limits — a disqualifying factor for many catalogs:

The Technical Migration Framework

Replatforming is a data engineering problem. Treating it as a copy-paste exercise is how businesses lose customer history and tank organic search rankings. A professional migration follows a strict four-phase pipeline.

Phase 1: Extract Historical Data via API (Never CSV Alone)

Shopify's APIs paginate data. A store with 500,000 historical orders cannot export them in a single call — the REST API returns a maximum of 250 records per page, requiring cursor-based pagination across thousands of requests. Write extraction scripts that respect Shopify's GraphQL rate limits (2,000 point bucket, restoring at 100 points/second) and load into a staging database before any transformation work begins.

CSV exports miss metafields, variant option relationships, and all app-owned data. For any production migration, treat CSV as a secondary validation tool, not the primary extraction mechanism.

Phase 2: Transform the Product Catalog Schema

Every platform structures catalog data differently. Your ETL pipeline must transform Shopify's JSON payloads to match the target platform's schema before loading. Skipping this step and importing raw Shopify data is the primary cause of broken filtering, missing specifications, and variant combination errors post-launch.

Shopify stores variants as flat objects with string-based option fields:

{
  "id": 12345,
  "title": "Large / Red",
  "option1": "Large",
  "option2": "Red",
  "sku": "SHIRT-L-RED",
  "price": "29.99"
}

BigCommerce uses a relational option structure where options are typed entities with defined display names:

{
  "id": 67890,
  "product_id": 111,
  "sku": "SHIRT-L-RED",
  "price": 29.99,
  "option_values": [
    { "id": 12, "label": "Large", "option_display_name": "Size" },
    { "id": 14, "label": "Red", "option_display_name": "Color" }
  ]
}

Shopify stores product tags as comma-separated strings; BigCommerce uses distinct category arrays. Shopify metafields map to BigCommerce custom fields, but the field type system differs — Shopify's typed metafields (color, dimension, rating) must be mapped to BigCommerce's untyped custom field strings, with potential loss of structured metadata. These schema mismatches are precisely where automated CSV importers produce silently broken catalogs.

Phase 3: Rebuild the App Ecosystem

Your Shopify store likely relies on apps for reviews (Yotpo, Okendo, Stamped), email marketing (Klaviyo), loyalty programs (Smile.io, LoyaltyLion), helpdesks (Gorgias, Zendesk), and subscription billing (Recharge, Skio). Because support macros are often hardcoded with Shopify-specific order variables, replatforming frequently forces teams to evaluate Gorgias alternatives or Zendesk alternatives that integrate natively with the new system. Before committing to a target platform, verify that each of these tools has a native integration — not a generic webhook-based connection — with your destination. App-specific data (review content, loyalty balances, subscription records) is stored in the app vendor's database, not in Shopify. Extraction requires direct API engagement with each vendor, and some vendors charge for historical data exports or don't support them at all.

Phase 4: Execute the 301 Redirect Architecture

This is the highest-risk step for business continuity. A missed redirect does not just lose one URL — internal links, sitemaps, and backlinks compound the damage.

The process:

1. Crawl your live Shopify store using Screaming Frog or Sitebulb to capture every indexed URL
2. Map every /products/ and /collections/ URL to the new platform's URL structure
3. Implement redirects before DNS cutover — test them in a staging environment against your actual crawl output
4. Submit an updated XML sitemap to Google Search Console immediately after launch
5. Monitor 404 errors in Google Search Console for 60 days post-launch

Most stores experience a temporary 10–30% organic traffic dip in the first 30–60 days post-migration even with correct redirect implementation, as Google reprocesses the crawl. Recovery to baseline typically occurs within 60–120 days if redirect implementation is complete and canonical tags are correct. Incomplete redirects extend this recovery period indefinitely.

For the full pre-launch and post-launch checklist, see our ecommerce migration checklist.

How to Choose: Decision Framework with Disqualifying Conditions

This is not a feature preference exercise. Each platform has hard constraints that disqualify it for specific requirements. Use disqualifying conditions first — eliminate platforms that can't meet your non-negotiable requirements, then compare the survivors on cost and fit.

Step 1: Apply disqualifying filters

Step 2: Select from remaining candidates

Don't migrate because a competitor looks cheaper on the pricing page. Migrate because your current platform's constraints are generating a quantifiable cost — in developer hours, conversion losses, or GMV-tier fees — that exceeds the migration investment and ongoing platform differential.

What Actually Migrates From Shopify: Pre-Migration Audit Checklist

Run this audit before signing a migration contract:

• Inventory your Shopify app stack. For each app: Does the destination platform have a native integration? Does the app vendor support historical data export? What is the cost of migration or recreation?
• List all products with >250 variant combinations. These are incompatible with Squarespace and require manual work on any platform.
• Identify all metafield namespaces in use. Plan the API extraction script and the field mapping to the target platform's equivalent.
• Confirm that all downstream systems (WMS, ERP, 3PL, marketplace feeds) reference products by SKU, not by Shopify product or variant ID.
• Export all Shopify Flow automations and Shopify Scripts logic. If Scripts are in use, the August 28, 2026 sunset deadline creates a hard migration deadline independent of platform choice.
• Run a crawl of your live store to establish your redirect map baseline before any work begins.
• Confirm your customer reactivation email sequence is ready for deployment on DNS cutover day — you will not have customer passwords.
