ApiNotes turns OpenAPI and Swagger specifications into hosted interactive API documentation and changelogs that flag breaking changes. It supports OpenAPI 3.0, 3.1, and 3.2, as well as Swagger 2.0, in YAML or JSON. Generated documentation can show endpoint parameters, response schemas, code examples in 10+ programming languages, and a Try-It-Now console. Users can paste, upload, or link a specification and publish the documentation on an ApiNotes subdomain. A GitHub Action can publish updated specifications on merge; the Team plan also lists pull request comments about breaking changes. The free Starter plan supports one public API, retains the last 10 changelog releases, and allows up to 25 subscribers and one team member. Team costs 19.00 USD per month and includes five APIs, private docs, full changelog history, unlimited subscribers, a custom domain, and five team members. Additional APIs are listed at £5/API. Team has a 14-day trial with no credit card required. Postman, Bruno, and Insomnia integrations are marked as coming soon.

Who it is for

ApiNotes suits developers who publish API references from OpenAPI or Swagger specifications and want changelog tracking. The free plan fits a single public API; teams needing private docs or more APIs can consider Team.
