Generate an API Changelog

Optic automatically generates a Stripe-style changelog and adds to it whenever you push new API changes.

Publish an accurate changelog

Optic understands the entire history of your API. Now you can publish accurate API changelogs without writing them yourself.

The open source history command walks your Git history and generates a markdown changelog:

optic history openapi.yml

Create an interactive changelog, and subscribe to API changes with Optic Cloud:

optic api add openapi.yml --history-depth=0
"To deliver a high quality API we need to be working API-first, and keeping track of the promises we have made to consumers. API-first has always been hard, Optic is the first tool we have found that makes it easy to quickly build and safety extend our APIs. "
