Summary

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