Stoplight is a aPI design, documentation, and governance platform with OpenAPI support. It handles api design, mock servers, style guides, and docs, and it's best suited for api teams wanting design-first api development. It has been around since 2015, giving it a 11-year head start in building out integrations and refining the product.

The free plan is free for 1 project — enough for most people to evaluate whether it fits. It works well for mid-size teams that need more structure than a basic tool but less overhead than enterprise platforms.

Includes Mock Servers as a core feature, purpose-built for api development workflows
