eCommerce Platform Comparison 2026: Complete Matrix

Every comparison in this guide scores platforms across the same eight dimensions. The weights shift by merchant stage — an early DTC brand cares more about time-to-launch than international complexity, while a global enterprise inverts those priorities — but the evaluation surface is constant. This is the scaffolding we use on client re-platforming engagements before we recommend a direction.

Hosted SaaS is the default recommendation for anyone under about $20M GMV without a strategic reason to self-host. You trade some customization for reliability, managed infrastructure, PCI compliance, and a fast path from idea to first sale. Shopify sits at the center of this category but it is not the only option — and for some merchant types it is actively the wrong fit. For deeper benchmarks across the category, review our eCommerce statistics 2026 and Shopify platform growth data.

Shopify and Shopify Plus

Shopify is the default answer for most DTC, fashion, beauty, food, and consumer goods brands. The app ecosystem is the widest in commerce, checkout converts well, and the platform reliability is the best in the category. The catch is predictable: Shopify Payments pressure, app subscription creep, theme limitations on customization outside Hydrogen, and a Plus upgrade path that crosses a steep price cliff. Plus is genuinely worth it above about $2M GMV when you need checkout extensibility, B2B, or multi-storefront, but it is not a silver bullet.

BigCommerce

BigCommerce is the strongest Shopify alternative in the hosted category. Zero transaction fees on any processor, deeper native B2B (company accounts, price lists, quoting), and Multi-Storefront natively supported. The app ecosystem is smaller but the features you need most often ship natively. It underperforms Shopify on theme breadth, checkout conversion benchmarks, and raw app depth, but it wins for brands with complex catalogs, B2B requirements, or strong opinions about payment processors.

Wix, Squarespace, Ecwid, Square Online

All four ship credible commerce storefronts for merchants under about $500k GMV where commerce is a feature of a broader content or POS strategy. Squarespace suits design-driven content brands with a small store attached. Wix suits small businesses that want a single tool for marketing site and store. Ecwid embeds commerce into existing sites cheaply. Square Online is the obvious choice if Square is already your POS. None scale past $1-2M without painful re-platforming, and none are designed for headless or agentic commerce.

Open-source commerce trades SaaS reliability for code ownership and license-free licensing. The tradeoff looks attractive on a spreadsheet but compounds quickly in production: hosting, security patching, plugin coordination, PCI scope, and the engineering hours required to keep everything current. Choose open source when code ownership is strategic — not to save license fees.

WooCommerce

WooCommerce wins for brands that treat content and commerce as one stack and already operate a WordPress site. The plugin ecosystem is massive, editorial control is unmatched, and development talent is cheap and plentiful. The operational cost comes from plugin coordination, update cycles, and managed hosting past $500k GMV — sites that skip managed hosting typically face cascading issues with checkout, caching, and security patches. Past $2-3M GMV, the cost of running WooCommerce well usually exceeds Shopify Plus.

Adobe Commerce and Magento Open Source

Adobe Commerce remains the enterprise B2B reference platform. Native quoting, negotiated pricing, company accounts, shared catalogs, multi-website and multi-store architecture — all of this ships out of the box. Licensing runs into six figures per year for Adobe Commerce Cloud, and the implementation partner ecosystem has thinned since the Adobe acquisition, but nothing else in commerce matches its B2B depth without custom work. Magento Open Source gives you the same core platform without the Adobe features or support contract — worth it only with experienced in-house Magento engineers.

PrestaShop, OpenCart, Spree Commerce

PrestaShop has a strong European SMB base, particularly in France and Spain, with solid multilingual and multi-currency handling. OpenCart is the lightweight PHP option for merchants comfortable on shared hosting. Spree is a Ruby on Rails commerce framework that suits engineering teams already operating a Rails application and wanting commerce as an extension rather than a bolt-on. All three have narrower ecosystems than WooCommerce or Magento and require closer engineering ownership.

Headless and composable commerce win when the front end has to do something the monolithic storefront cannot — multi-channel, multi-brand, content-driven merchandising, mobile-first PWA, or a shared design system across commerce and non-commerce properties. Most enterprise headless projects we review in 2026 are motivated by agentic readiness, performance targets, or a desire to unify content and commerce on a single Jamstack front end.

Salesforce Commerce Cloud

Salesforce Commerce Cloud (formerly Demandware) remains the reference platform for Salesforce-native enterprises that need commerce to tie into Service Cloud, Marketing Cloud, and Data Cloud. Implementation partner fees are significant and the platform moves slower than pure MACH alternatives, but the integration value is meaningful when the rest of your stack is Salesforce. Without that native fit, CommerceTools or Shopify Plus usually outperform on time-to-value.

CommerceTools, Commerce Layer, Elastic Path

CommerceTools is the enterprise MACH reference — multi-tenant, infinitely customizable, priced accordingly. Commerce Layer specializes in multi-market, multi-currency global brands and pairs unusually well with Jamstack content stacks. Elastic Path leans into complex B2B and subscription commerce. Any of the three works in production at scale — the choice is driven more by procurement fit and implementation partner availability than by feature parity.

Shopware, Saleor, Medusa, Vendure, Swell

Shopware dominates European enterprise B2B and has a strong PWA front end. Saleor is the GraphQL-native open-source option and suits Python and TypeScript teams equally. Medusa has become the fastest-growing open-source commerce project — Node.js, TypeScript, Postgres — and is credible for brands up to $20M GMV when the team can operate it. Vendure is the TypeScript-first GraphQL alternative and appeals to engineering-led mid-market teams. Swell is a niche but strong hosted-headless option for subscription and DTC brands that want SaaS reliability without Shopify constraints.

Marketplaces look like commerce but operate differently — vendor onboarding, split payments, commission models, dispute resolution, and trust and safety features dominate the roadmap. Using a pure commerce platform for a marketplace almost always results in a painful pivot within two years. If the business model depends on third-party sellers, start on marketplace-native infrastructure.

Most re-platforming projects fail on the scope side, not the tech side — teams pick a platform fit for where they want to be in five years rather than where they are now. This framework maps platforms to GMV stages and to the four dominant commerce motions: B2C, B2B, DTC, and omnichannel. Use it as a starting point and let the methodology scorecard from section one adjust the final pick.

SMB — under $1M GMV

The overwhelming majority of new commerce brands should start on Shopify Basic or Advanced. Time-to-launch is the dominant factor, and Shopify ships the shortest path from idea to first sale. BigCommerce is a credible alternative if zero transaction fees on a non-Shopify processor is a deal-breaker, or if B2B features matter from day one. Avoid WooCommerce at this stage unless the team already operates a WordPress site — the operational tax is disproportionate at SMB scale.

Mid-market — $1M to $10M GMV

This is the Shopify Plus crossover band. Around $2M GMV, checkout extensibility, Shopify Functions, and Shopify Markets Pro start paying back the higher license. BigCommerce Pro holds its own on B2B-heavy mid-market, and Adobe Commerce starts making sense for complex B2B or hybrid B2B/B2C manufacturers. This is also where a re-platform from WooCommerce or Wix typically becomes urgent — not because the current platform technically cannot serve the business, but because operational friction compounds.

Scale — $10M to $100M GMV

Scale merchants have outgrown one-size-fits-all SaaS but have not yet hit the complexity that demands pure MACH. Shopify Plus with Hydrogen covers the majority of scale B2C and DTC brands. CommerceTools and Commerce Layer start to appear for multi-brand, multi-market, or content-heavy operators. Adobe Commerce continues to dominate complex B2B. Decisions here are as much about organizational capability — can the team operate a composable stack — as about features.

Enterprise — $100M+ GMV

At enterprise scale the platform is one component of a broader stack that includes OMS, PIM, CDP, CMS, and loyalty. MACH-native options dominate — CommerceTools, Commerce Layer, Elastic Path — because they integrate cleanly with whatever OMS, PIM, and personalization layer the organization has already selected. Salesforce Commerce Cloud remains the default for Salesforce-native enterprises. The winning platform at this scale is usually the one with the strongest local partner ecosystem, not the one with the best feature list.

The two hardest parts of any re-platforming project sit on opposite ends of the timeline — protecting existing organic traffic on the way in, and future-proofing the stack against the agentic-commerce shift already underway in 2026. Both demand explicit planning. Treating either as a post-launch concern turns a nine-month project into an eighteen-month project.

Re-platforming cost and timeline

Mid-market re-platforming projects typically run six to twelve months end-to-end: one month on discovery and URL audit, two to three months on build, one month on data migration rehearsal, two months on testing and content migration, and a careful cutover window with a 48-hour war room. Enterprise MACH migrations run twelve to twenty-four months. Budget the full timeline before promising a launch date — compressed cutovers are the single biggest cause of re-platforming traffic losses.

SEO preservation

The non-negotiables on every migration: a complete URL export from Google Search Console and Ahrefs or Semrush, an explicit 1:1 301 redirect map to new URLs, preserved structured data (Organization, Product, Breadcrumb, Offer), canonical tag parity, XML sitemap resubmission, and a Screaming Frog crawl of staging against the old URL list. Skipping any of these produces a traffic dip that typically takes six-plus months to recover. Our eCommerce SEO checklist walks through the full pre-launch QA.

Data migration

Customers, orders, subscriptions, loyalty balances, store credit, product catalog, category tree, reviews, blog content, and historical analytics all need a migration plan. Most platforms offer native importers for Shopify-to-Shopify or Magento-to-Adobe Commerce. Cross-platform migrations (WooCommerce to Shopify, Magento to CommerceTools) usually require middleware such as LitExtension, Cart2Cart, or custom ETL work. Rehearse the full migration at least twice before cutover and validate order history completeness against source data.

2026 agentic-commerce readiness

Agentic commerce moved from speculation to measurable traffic in 2026. ChatGPT Checkout, Perplexity Shopping, and Amazon AI Shopping now drive real purchases, and platforms are differentiating on how well they expose product data, inventory, and checkout to these agents. The state of the art varies widely across platforms.

The practical conclusion: if agentic channels matter to your two-year roadmap, Shopify is the lowest-friction bet among hosted platforms and the MACH stack (CommerceTools, Commerce Layer, Saleor) gives you the API surface to implement agentic integrations on your own terms. Platforms without clean structured data will underperform in ChatGPT Checkout, Perplexity Shopping, and Amazon AI Shopping indexing through 2026 and 2027.
