Best open source ecommerce platforms 2026 compared

There is no single best open source ecommerce platform in 2026. WooCommerce suits a store built around WordPress, PrestaShop a European merchant wanting a complete shop, Shopware a growing business comfortable with paid tiers later, and Medusa a TypeScript team building its own storefront. The useful comparison is not a feature count but three questions: what the licence actually allows, which skills the stack demands, and who pays for what once the shop is live. All facts below were checked on official pages on 1 November 2026.

A disclosure: I build shops with Sylius and custom code, so I have an interest in this comparison, and Sylius appears in the table for that reason. I do not sell the other four. Treat my preferences accordingly and check the links.

The licence is not the whole story

MIT is permissive. GPL and OSL include conditions about redistributing and sharing modified code, which can matter if you plan to sell a product built on the platform rather than run your own shop. If that is your plan, ask a lawyer to read the exact licence text. For a merchant simply running a store, this rarely changes the decision.

The fine print of each vendor's commercial offer often matters more. Shopware is the clearest example. Its pricing page says the Community Edition core has no licence fee, but under its Fair Usage Policy, shops generating more than 1 million euros in gross merchandise value over the preceding 365 days need a paid plan to keep access to the Shopware Account and Store. You may keep using the software independently, yet you would lose the convenience those services provide. B2B quotes and purchasing approvals are listed from the Evolve plan, so check where your must have features sit before you choose.

Medusa has a similar boundary: its licence file excludes the Enterprise Edition materials from MIT. That does not disqualify it, but you should know which parts you are actually relying on.

Which stack can you keep alive?

The technology question is really a staffing question. WooCommerce extends WordPress, so it brings access to a very large pool of generalists, along with the need to keep WordPress, your theme and your plugins compatible with each other. PrestaShop and Shopware both rely on PHP and Symfony, though PrestaShop still carries a long history: my article on its performance and Symfony migration covers that in detail.

Medusa stands apart. It is headless, so your developers build or adapt a storefront, with a Next.js starter available. A TypeScript product team may find this natural, while a shop owner without developers will find it a poor fit. The same is true of Sylius in the PHP world, even though it does include a classic shop. My Sylius and Medusa comparison goes deeper into their architecture.

The real cost after the free download

Vendors say it themselves. WooCommerce's pricing page confirms no monthly subscription and no revenue share, and estimates hosting at roughly 25 to 350 dollars a month for most stores. PrestaShop's Classic edition is free to download, with hosting and domain excluded. Shopware says you arrange and pay for hosting, implementation and maintenance yourself on the Community Edition, and that extensions and payment processing may add fees.

Those are the visible lines. The expensive ones are harder to see: a developer who tests updates, a person who answers when checkout breaks on a Saturday, and the work required by each major version. PrestaShop itself warns that version 9 is a major version where some modules and themes may need updates. Ask every supplier for a three year estimate which includes at least one major upgrade.

A quick way to decide

Start from your situation. If your business already runs on WordPress and sells a modest catalog, WooCommerce is the natural first candidate. If you want a full store with many European modules and a hosted option as a safety net, consider PrestaShop. If you expect strong growth and accept the idea of a vendor plan, look at Shopware. If you have a TypeScript team and need a custom buying experience, look at Medusa. If your business rules are complex and you have or can hire PHP skills, Sylius deserves a look, and that is where I can help directly.

When open source is the wrong answer

Open source gives you control, and you pay for control with responsibility. If you have no technical person, a small catalog and no unusual process, a hosted platform such as Shopify will probably serve you better, at least in the beginning. Its monthly fee buys you freedom from updates and server work. Moving to open source can wait until you reach a real limit, such as transaction costs, a complicated B2B process or a need to own your data model.

Next step

Write down your catalog size, your sales channels, your must have integrations and the name of whoever will maintain the store. With that page, most of the options above eliminate themselves.

I reply within 24 working hours, you speak directly with the person who writes the code, and I will tell you if another platform or provider fits better.
