About Redocly
Redocly builds API reference documentation from an OpenAPI description. Its tools also check whether that description is clear enough for developers and AI agents to use correctly.
What it does
You keep your API description in your repository, and Redocly turns it into a reference site with try-it features. Its checks can run on every pull request and report gaps, such as missing examples or undocumented error responses. The platform also offers an MCP server built from your docs, along with SDKs and workflow tests, some of which are still in early access.
Key features
- Reference docs generated from an OpenAPI file
- Lint checks that run on each pull request
- Try-it requests inside the reference docs
- An MCP server built from your API docs
- Typed SDKs in several languages, in early access
Who it's for
Redocly suits API teams that publish public or partner APIs and want their documentation checked as part of normal development. It is a good match for companies that already write OpenAPI descriptions and want those files to drive the docs.
Pricing and good to know
The Redocly CLI is open source under the MIT license, and the platform offers a 30-day free trial. The site says every plan includes unlimited seats. Some newer features are early access, so check which parts are available on your plan before you rely on them.
