Reviewers largely see Medusa as a strong open-source, self-hosted alternative to Shopify for teams that want control and customization. Users repeatedly praise its flexibility, headless approach, and smooth fit with modern stacks, saying it works well for building tailored ecommerce projects and keeps improving over time. The tradeoff is that it is more developer-oriented: some coding knowledge helps, and one user specifically calls out weak payment integrations, noting PayPal does not work as expected.
