Best Open-Source E-Commerce Platforms

Open-source platforms give you complete control and zero licensing fees, but demand technical chops to customize and deploy. WooCommerce dominates this space by sheer gravity—it powers 39% of all online stores—making it the obvious choice if you're already in WordPress. PrestaShop and OpenCart work standalone but lack WooCommerce's ecosystem advantage.

Final Thoughts

WooCommerce is the only real choice unless you need to avoid WordPress entirely. If you do, PrestaShop's European community and extension marketplace make it the stronger alternative.
