Best Open Source E-commerce Platforms

E-commerce is where open source is least "free." The software costs nothing, and then you pay for hosting, a payment gateway, someone to maintain it, and your own time keeping the checkout working. Before comparing tools, accept that the ongoing costs are the product. The platform just decides how big those costs are.

WooCommerce (GPL)

WooCommerce is a plugin on WordPress, GPLv2, and it is the fastest path from zero to a working store that most teams will find. Themes and plugins cover every need, thousands of developers can maintain it, and a small store on good shared hosting plus a Razorpay or Cashfree plugin is live in a day. The cost is the long tail: plugin conflicts, performance decay, and a security patch routine that is non-negotiable on a store that handles payments. It suits the shop owner, less the engineering team.

Medusa (MIT)

Medusa is a headless commerce platform, MIT licensed, built in Node and TypeScript with an API-first design and a storefront you build yourself. Its strength is that the checkout, cart, inventory, and order logic are cleanly separated from the frontend, so you can ship a custom storefront on any stack. The cost is that there is no ready storefront to switch on. You are hiring for it. Medusa suits a team that already builds web apps and wants commerce as a service layer rather than a turnkey site.

Saleor (BSD-3)

Saleor is the GraphQL-first commerce platform, BSD-3-Clause, built on Python and Django. Its schema-first approach is its identity: the entire commerce API is generated from a GraphQL schema, which is powerful and exacting. For teams that want full control over the frontend and like GraphQL, it is the cleanest codebase in this list. The cost is the same as Medusa: you build the storefront, you own the operations, and Saleor's own hosted platform is where the polished parts live. A solo shopkeeper should not start here.

Sylius (MIT)

Sylius is a Symfony-based commerce framework for PHP, MIT licensed, aimed at developers building custom, mid-size commerce platforms. It has a solid admin, a strong plugin system, and a long history behind agencies that use it for client work. It is not a download-and-configure store. It is a foundation you extend, and the extension work is real engineering. Sylius makes sense when you are building a bespoke store with specific catalogue, pricing, or multi-vendor requirements, and you have PHP developers available.

PrestaShop (OSL 3.0)

PrestaShop is the PHP store platform that is huge in Europe and rare in India, licensed under OSL 3.0. It is more of a finished store than the frameworks above: themes, modules, a decent admin, multi-currency and multi-language support out of the box. The tradeoffs are the same as WooCommerce with a smaller ecosystem: module quality varies, and the community is lighter in Asia. It is a fine choice if your audience and integrations are European.

Bagisto (MIT)

Bagisto is a Laravel-based commerce platform built by Webkul, an Indian company, MIT licensed. That provenance matters in practice: it is the platform here with the most familiar learning path for Indian PHP and Laravel developers, with local payment gateways and tax configuration well documented. It is more finished than Sylius and less turnkey than WooCommerce. For an Indian team that wants Laravel rather than WordPress, and wants the core commerce features already built, Bagisto is the honest recommendation.

Magento Open Source (OSL 3.0)

Magento Open Source is the free layer of Adobe Commerce, licensed under OSL 3.0, and it is the most powerful and most demanding platform here. It handles huge catalogues, multi-store, complex pricing, and enterprise workflows, and it punishes you for the privilege: a real deployment needs serious hosting, Redis and Elasticsearch or OpenSearch in front, and a developer who knows the platform. Adobe's investment goes into the commercial product, so community updates are slower and the support burden is yours. Choose it only when your requirements are genuinely enterprise scale, and budget accordingly.

An Indian example

Take a small D2C brand in Jaipur selling home decor, a few hundred orders a month, one founder and a designer. The correct answer is almost always WooCommerce or Bagisto with Razorpay or Cashfree. The founder gets a working store in a week, UPI and cards work through the gateway plugin, and the maintenance bill is a few thousand rupees a month in hosting plus a developer on retainer for updates. The same brand with a two person engineering team, and a subscription model plus a custom app planned for next year, should be looking at Medusa or Saleor instead, because the storefront is the app and the commerce engine is the boring part they want under control.

The real costs

Payment gateways are where the money leaves: Razorpay, Cashfree, PayU, and Instamojo all charge per transaction, and integration is a plugin on WooCommerce and a project everywhere else. Hosting is cheap until it is not, a flash sale is the fastest way to learn this. Maintenance is the number everyone skips, platform updates, security patches, and gateway API changes add up to a standing monthly bill in developer time. Open source e-commerce saves you the licence fee and makes you the product owner. That is a good trade only if you are prepared to be one.
