Endrel
What it is
Endrel is a hosted workspace for API documentation, bringing specifications into a searchable space and using AI review to flag documentation drift. It imports OpenAPI, Swagger, and Postman collections and rechecks specifications when they change. The reviewer can flag schema drift, missing endpoints or examples, inconsistent conventions, and breaking changes. Front-end, back-end, and QA teammates can comment on endpoints, identify mismatches, and resolve them inline. Workspace- and service-level permissions support public references or restricted internal APIs. Endrel also provides a REST API. Its free Sandbox plan includes one workspace, three projects per workspace, four members per workspace, and one environment per workspace; GraphQL support, live API testing, and global search are not included. Localhost costs ₹1,499/mo, or ₹14,990/yr, and adds GraphQL support and live API testing, but not global search. Founding Access is free for the first 10 teams; long-term pricing and lifetime-free access have not been promised. Endrel advises against importing secrets or production credentials during Founding Access.
