WooCommerce is the answer for Shopify merchants whose real grievance is fees and lock-in. As an open-source WordPress plugin, the core is free — there's no monthly platform fee and no forced transaction cut — and you own your store and data outright. The catch is that responsibility shifts to you: hosting, security, updates and premium extensions become your cost and your job, and setup is more technical than Shopify's turnkey experience. For a merchant with some technical comfort who wants control and to escape platform fees, WooCommerce is the classic destination. Migration tools exist but plan for real setup work.
