Best Headless Ecommerces of 2026

BigCommerce Catalyst is the BigCommerce-bundled headless framework for merchants whose evaluation centers on BigCommerce ecosystem plus Next.js framework. Launched 2024 by BigCommerce (NASDAQ: BIGC), Catalyst built around the thesis that BigCommerce merchants should have a first-party Next.js storefront framework parallel to Shopify Hydrogen, eliminating the choose-a-framework decision for headless rebuilds.

Four tiers. Catalyst OSS is MIT-licensed Next.js storefront framework with BigCommerce Storefront API and free hosting on Vercel or Netlify with paid BigCommerce. BigCommerce Standard at $39 monthly with $50K annual sales cap covers Catalyst plus Storefront API and standard apps. BigCommerce Plus at $105 monthly with $180K cap adds customer groups and abandoned cart. BigCommerce Pro at $399 monthly with $400K cap covers premium support, multi-store, and custom SSL.

The load-bearing wedge is the BigCommerce ecosystem bundle plus the Next.js framework. Where Hydrogen requires Shopify and standalone headless platforms require full custom integration, Catalyst ships into existing BigCommerce subscriptions with admin, apps, and integrations preserved; for BigCommerce merchants going headless, Catalyst eliminates the migration overhead. The catch is the BigCommerce ecosystem lock-in and annual sales caps that force tier upgrades as GMV grows.

Vendure is the TypeScript modular open-source headless commerce engine for TypeScript-first engineering teams whose evaluation overlaps Medusa on Node.js stack but adds GraphQL-first admin and shop API. Founded 2018 in the UK and community-maintained, Vendure built around the thesis that headless commerce should ship as TypeScript-first modular framework with GraphQL admin out of the box.

Four tiers. Open Source is free under MIT license with TypeScript headless commerce and GraphQL admin plus shop API. Cloud Starter at €49 monthly hosts single-region with standard plugins. Cloud Pro at €199 monthly opens multi-region plus auto-scale with premium plugins and Slack. Enterprise is custom-quoted around $2K monthly with dedicated cluster, SSO, custom plugins, and dedicated CSM.

The load-bearing wedge is the TypeScript-first modular plus GraphQL admin. Where Medusa ships JavaScript-first modular and Saleor ships GraphQL-first Python, Vendure overlaps both with TypeScript-first modular plus GraphQL admin in one platform; for TypeScript-first teams wanting GraphQL admin, Vendure covers both wedges. The catch is the smaller mainstream brand recognition than Medusa and the absence of US enterprise reference base.

Swell is the SaaS bundled headless commerce platform for merchants whose evaluation requires B2C plus B2B plus subscriptions in one platform without OSS-self-host or enterprise procurement complexity. Founded 2015 in San Francisco and bootstrapped, Swell built around the thesis that SaaS headless commerce should ship all three commerce channels (B2C retail, B2B wholesale, subscriptions) in one platform rather than requiring separate vendors per channel.

Four tiers. Free trial covers 30 days with hosted headless commerce. Standard at $299 monthly plus 1 percent transaction fee covers B2C plus B2B plus subscriptions with standard apps and GraphQL. Plus at $1,499 monthly plus 0.3 percent fee adds multi-store and multi-currency with premium apps and Slack. Enterprise is custom-quoted around $5K monthly with dedicated cluster, SLA, SSO, and custom integrations.

The load-bearing wedge is the three-channel bundle plus the SaaS managed hosting. Where Saleor and Medusa require self-host plus separate subscriptions plugin and commercetools requires enterprise procurement, Swell ships all three channels in one SaaS subscription; for merchants whose business spans retail plus wholesale plus subscriptions, Swell eliminates the multi-vendor split. The catch is the transaction fee on top of monthly subscription and the smaller reference base than Saleor or Medusa.

Medusa is the Node.js modular open-source headless commerce engine for JavaScript-first engineering teams whose evaluation centers on MIT licensing plus Node.js plus Postgres stack. Founded 2019 in Copenhagen and backed by Y Combinator, Medusa built around the thesis that headless commerce should ship as a modular Node.js engine that JavaScript developers can extend with TypeScript modules rather than learning a new platform language.

Four tiers. Open Source is free under MIT license with Node.js plus Postgres plus Redis stack and headless API plus admin UI. Cloud Starter is custom-quoted around $200 monthly with hosted Medusa Cloud and standard plugins. Cloud Pro is custom-quoted around $1K monthly with multi-region, auto-scaling, plugin store, and Slack support. Enterprise is custom-quoted around $4K monthly with dedicated cluster, SSO, custom plugins, and dedicated CSM.

The load-bearing wedge is the modular Node.js architecture plus the MIT licensing. Where Saleor ships GraphQL-first Python and commercetools ships enterprise Java, Medusa ships modular TypeScript modules that JavaScript developers can extend without learning new languages; for JavaScript-first teams already running Node.js services, Medusa fits the existing toolchain. The catch is the smaller mainstream brand recognition than commercetools and the absence of GraphQL-first design that Saleor ships.

commercetools is the enterprise MACH-architecture headless commerce platform for Fortune 500 organizations whose evaluation centers on procurement-grade vendor relationship plus deepest enterprise feature surface. Founded 2006 in Munich and backed by Insight Partners, commercetools built around the thesis that enterprise commerce should ship as Microservices, API-first, Cloud-native, Headless (MACH) architecture rather than monolithic storefronts.

Four tiers. Free trial covers GraphQL plus REST headless API with multi-language and multi-currency. Composable is custom-quoted around $10K monthly ($120K annual) with Frontend Studio, Studio editor, multi-channel, and multi-store. Enterprise is custom-quoted around $25K monthly ($300K annual) with dedicated multi-tenant, SLA, SOC 2, audit, and RBAC. Premium is custom-quoted around $50K+ monthly ($600K+ annual) with on-prem and private cloud.

The load-bearing wedge is the enterprise reference base plus the MACH architecture. Where Saleor, Medusa, Vendure ship OSS modular and Hydrogen plus Catalyst bundle with existing storefront platforms, commercetools ships the enterprise procurement-grade vendor relationship that Fortune 500 companies need; for organizations replacing legacy SAP Commerce or Oracle ATG, commercetools is the safe migration choice. The catch is the Composable $96K annual entry tier excludes SMB and lower mid-market entirely.

Saleor is the GraphQL-first open-source headless commerce platform for engineering teams whose evaluation centers on GraphQL-API ergonomics plus permissive BSD-3 licensing. Founded 2012 in Wroclaw by Mirumee Software, Saleor built around the thesis that headless commerce should ship as GraphQL-first API design (matching modern frontend tooling like Apollo and Relay) rather than REST plus optional GraphQL.

Four tiers. Open Source is free under BSD-3 license with GraphQL-first headless commerce self-hosted on Postgres plus Redis. Cloud Free Trial covers 30 days with hosted Saleor Cloud. Cloud Pro is custom-quoted around $3.5K monthly with hosted multi-channel and apps. Enterprise is custom-quoted around $8K monthly with multi-region, dedicated CSM, and SOC 2.

The load-bearing wedge is the GraphQL-first design plus the BSD-3 license. Where commercetools ships REST plus GraphQL and Medusa plus Vendure focus on REST or both, Saleor ships GraphQL as the primary API; for engineering teams whose frontend uses Apollo, Relay, or urql, Saleor's GraphQL-first design eliminates the REST-to-GraphQL adapter overhead. The catch is the smaller US enterprise reference base than commercetools and the Cloud Pro $3.5K monthly minimum for managed Cloud.

Shopify Hydrogen is the Shopify-bundled headless framework for merchants whose evaluation centers on Shopify ecosystem integration rather than standalone headless platforms. Launched 2021 by Shopify (NYSE: SHOP), Hydrogen built around the thesis that Shopify merchants should not have to leave the Shopify ecosystem to ship a custom storefront; the framework plus Oxygen hosting bundle into existing Shopify subscriptions.

Four tiers. Hydrogen OSS is MIT-licensed Remix-based framework with Storefront API access and free hosting on Oxygen with paid Shopify. Shopify Basic at $39 monthly plus transaction fees ships Storefront API, Hydrogen, and Oxygen hosting. Shopify Plus at around $2,300 monthly annual covers multi-store, scripts, Flow, wholesale, B2B, and Launchpad. Shopify Plus Enterprise is custom-quoted around $8K monthly with dedicated cluster, SLA, and Merchant Success.

The load-bearing wedge is the Shopify ecosystem bundle. Where commercetools, Saleor, Medusa, and Vendure are standalone headless platforms requiring full custom development, Hydrogen ships into existing Shopify subscriptions with admin, payments, apps, and integrations preserved; for Shopify merchants going headless, Hydrogen eliminates the migration overhead of leaving Shopify. The catch is the Shopify ecosystem lock-in and the Plus $2,300 monthly minimum for advanced features that smaller commercial alternatives ship at lower entry pricing.
