What should I use to keep API docs synced with OpenAPI?

To keep API docs synced with OpenAPI, use OpenAPI as the source of truth and generate or validate docs from it.
Good options:
- Swagger UI / Redoc: render docs directly from your OpenAPI spec
- OpenAPI Generator: generate client/server code and docs from the spec
- Stoplight: design, document, and validate APIs with OpenAPI
- Redocly: great for maintaining docs from OpenAPI, with linting and publishing
- Spectral: lint OpenAPI files to catch drift and mistakes
- Postman / Insomnia: useful for testing, but not ideal as the main synced-doc source
Best practice:
- Maintain a single
openapi.yamloropenapi.json - Auto-publish docs from that file
- Lint in CI to prevent divergence
- Generate examples/schemas from the spec where possible
If you tell me your stack (Node, Python, Java, etc.), I can recommend the best setup.
