Grow, and monetize your app with unified AI gateway

We built itdoc to eliminate the gap between API code and its documentation. As developers, we were constantly frustrated by outdated API docs and the hassle of maintaining them manually or with error-prone annotations. itdoc solves this by automatically generating OpenAPI documentation directly from your test code—ensuring your docs are always accurate, up-to-date, and reflective of real behavior. No more syncing Postman, no more outdated Swagger annotations. Just write tests (which you should be doing anyway!) and get beautiful, reliable docs as a result. We’re incredibly proud to ship this with a simple setup, seamless Jest/Mocha support, and gorgeous Redoc-based outputs. We hope itdoc helps your team communicate better and move faster. Would love to hear your thoughts or feedback 🙏

We've documented usage instructions for users of NestJS and Fastify in addition to Express.
