Reviewers mostly see Medusa as a strong fit for developers who want an open-source, self-hosted alternative to Shopify with deep customization and control over the stack. Users repeatedly praise its flexibility, headless approach, and smooth fit with modern tools, saying it works well for building tailored stores and keeps improving over time. The main caveat is that it expects some coding knowledge, and one user calls out weak payment integrations, especially PayPal, as an area that still needs work.
