What is Stoplight?

Stoplight is an API design-first platform that lets teams create, prototype and document OpenAPI descriptions and JSON Schemas through a visual editor, reducing the need to hand-write specs. It includes automatically generated interactive documentation, hosted mock servers for parallel frontend and backend development, and style guide tooling to enforce consistency and governance across many APIs. Stoplight integrates with Git-based workflows so design artifacts can live alongside source code.

Stoplight was acquired by SmartBear in 2023 and continues to operate as a distinct product with its own paid plans, while some of its open-source tools have been integrated into SmartBear's SwaggerHub. Plans range from a limited free tier through Basic, Startup and Pro Team tiers billed per user, up to custom Enterprise agreements with SSO and dedicated support.
