Best Open Source E-commerce Platforms in 2026
Self-hostable engines you fully own, with no license fee and no per-order cut to a SaaS vendor.
WooCommerce remains the most widely deployed open-source pick for merchants already running WordPress, while Medusa and Saleor are the strongest headless options for developers building a fully custom storefront. PrestaShop and Magento suit teams who want a working store front out of the box instead of assembling one from an API. Every platform here is free to self-host under a real open-source license, so the only recurring cost is your own hosting and dev time, not a platform fee.
Most "best e-commerce platform" roundups mix in hosted SaaS tools that only look free until you hit a transaction fee or a product cap, and a few even call a proprietary hosted API "open" because its client SDK is on GitHub. From the 10,000+ tools Toolradar tracks, these are the open-source e-commerce platforms you can self-host and fully own, no transaction cut to a SaaS. Every engine below publishes its full source code, runs on infrastructure you control, and can be forked or modified without asking anyone's permission.
We WebSearched each platform's current license and self-hosting terms directly, not the vendor's marketing page, and dropped several tools that showed up in Toolradar's own e-commerce category but turned out to be hosted APIs or closed SaaS wearing an open-source label. Every pick that made the final list still ships a free, self-hostable edition of its core software with no revenue cap, has a public repository under active development, and has a real community around it. We also confirmed each one is still alive and shipping releases in 2026, since open-source e-commerce has a long history of abandoned forks.

Other E-commerce Platforms worth considering
Beyond the editorial top picks, these are also strong choices we evaluated.
What Is an Open Source E-commerce Platform?
An open-source e-commerce platform is software you download, install, and run on your own server or cloud account, with the full source code available to read, modify, and redistribute. Unlike a hosted SaaS store builder, no vendor holds your catalog, there's no monthly platform fee, and a pricing change on the vendor's side can't lock you out of your own data. You pay for hosting and, usually, developer time, instead of a subscription.
Not everything marketed as "open" is fully self-hostable. Some vendors publish an SDK or client library as open source while keeping the actual commerce backend as a closed, hosted API, which is a different product entirely. Every platform on this list ships a complete, runnable backend under a real open-source license, meaning you can take the code, host it yourself, and never touch the vendor's servers if you choose not to.
Why Self-Hosting Your Commerce Stack Matters
A hosted platform can raise its transaction fee, change its terms, or shut down and take your storefront with it. That risk is easy to underestimate until it happens: pricing models change, companies get acquired, and free tiers get discontinued with little notice. Self-hosting an open-source engine means the software keeps running on your own server even if the company behind it disappears or pivots its business model, because you hold the code, not a subscription.
The tradeoff is real. You take on hosting, security patching, and version upgrades yourself, or you pay a developer or agency to do it. For a store with steady revenue and access to technical help, that tradeoff usually pays for itself within a year or two compared to an ongoing SaaS platform fee. For a brand-new store with no developer on staff, a hosted platform's simplicity can still be worth the fee.
Key Features to Look For
GPL, MIT, BSD, and OSL all let you self-host for free, but copyleft terms like GPLv3 affect what you owe the community if you redistribute modified code. Know which one you're building on.
Check the commit history and release notes before committing engineering time. Several open-source carts from the 2010s are effectively abandoned even though their websites still list pricing.
Confirm what the platform needs to run (PHP and MySQL, Node and PostgreSQL, Ruby, or .NET) before picking one. Fighting an unfamiliar stack costs more time than any feature saves.
A platform with thousands of themes and modules saves months of custom development compared to one where every feature is a from-scratch build.
Headless engines like Medusa and Saleor ship an API and expect you to build the storefront. Monolithic platforms like PrestaShop and WooCommerce ship a working frontend out of the box.
A few commercial open-core platforms cap free use once a store passes a certain revenue threshold. Confirm the core software you're building on has no such ceiling before you commit.
Mistakes to Avoid
- ×
Picking a headless engine like Medusa or Vendure and underestimating the frontend build, since neither ships a ready storefront theme the way PrestaShop or WooCommerce do.
- ×
Confusing an open-source SDK with a self-hostable platform. Several 'headless commerce' brands publish open-source client libraries while keeping the actual backend as closed, hosted SaaS.
- ×
Choosing Magento for a small catalog. It's built for enterprise scale and needs real hosting and DevOps investment that a fifty-product store doesn't require.
- ×
Ignoring the license type. GPL and GPLv3 platforms (WooCommerce, OpenCart, Vendure) require you to open-source your own modifications if you redistribute them; BSD and MIT platforms (Medusa, Saleor, Spree, Sylius) do not.
- ×
Underbudgeting for hosting and maintenance. Free software still needs a server, backups, security patches, and someone to apply them.
Expert Tips
- →
Match the stack to your team, not the feature list. A PHP team building on WooCommerce or PrestaShop ships faster than the same team fighting an unfamiliar Node or Ruby framework.
- →
Test the admin experience before committing. Leaner open-source carts like OpenCart or Bagisto have simpler admin panels than enterprise options like Magento, which matters for whoever runs the store day to day.
- →
Budget for a managed hosting or cloud tier even on open-source engines. Medusa, Saleor, and Vendure all offer optional managed hosting if self-hosting turns out to be more overhead than your team wants.
- →
Check the extension marketplace before picking a headless option. WooCommerce and PrestaShop's plugin ecosystems can replace months of custom development that a newer, smaller platform would require building from scratch.
- →
Read the exact license before redistributing modified code, not just the marketing page. GPLv3 platforms like Vendure require you to release your own modifications under the same license unless you buy a commercial exception.
The Bottom Line
WooCommerce is the safest default if you already run WordPress, Medusa and Saleor are the strongest picks for a fully custom headless build, and PrestaShop or Magento work best when you want a complete store out of the box. From the 10,000+ tools Toolradar tracks, these are the open-source e-commerce platforms you can self-host and fully own, no transaction cut to a SaaS, so the real decision is which license and stack fits your team, not which platform claims to be free.
Frequently Asked Questions
What is the best open-source e-commerce platform?
There's no single best option. WooCommerce is the most widely used because it runs on WordPress and has the largest plugin ecosystem, Medusa and Saleor are the strongest picks for a custom headless storefront, and PrestaShop or Magento work well if you want a complete store front out of the box. The right choice depends on your team's existing stack (PHP, Node.js, Python, Ruby, or .NET) more than any single feature.
Is WooCommerce really free?
The WooCommerce plugin itself is free and open source under the GPL, and it costs nothing to install on a WordPress site you already host. You'll still pay for WordPress hosting, a domain, and likely a handful of premium extensions for advanced shipping, subscriptions, or payment gateways, so the total cost isn't zero, but the core software carries no license fee or revenue cap.
What's the difference between open-source and free e-commerce platforms?
Free platforms include hosted SaaS tools that charge no monthly fee but usually take a transaction cut and don't give you the source code. Open-source platforms like WooCommerce, Medusa, and PrestaShop give you the full codebase to self-host, modify, and own outright, with hosting as your main ongoing cost instead of a per-sale fee. A few platforms, like Saleor, offer both paths: self-host the open-source core for free, or pay for a managed cloud version.
Can I use an open-source e-commerce platform without coding?
Monolithic platforms like PrestaShop, WooCommerce, OpenCart, and Magento ship a working storefront and admin panel out of the box, so a non-developer can install one and start selling with minimal customization. Headless engines like Medusa, Saleor, Vendure, and Sylius ship only the backend API, so you or a developer need to build or plug in a separate storefront before you can sell anything.
Which open-source e-commerce platform is best for developers?
Medusa and Vendure are the strongest picks for JavaScript and TypeScript developers who want a modern, modular headless backend. Saleor suits teams comfortable with Python and GraphQL, and Sylius and Spree Commerce fit better if your team already works in Symfony/PHP or Ruby on Rails. All four are built API-first, unlike WooCommerce or PrestaShop, which assume a traditional storefront.
