Keep your promises

APIs are promises. If you have not documented your API, you do not know what promises you have made. Optic helps rapidly documents all your APIs and prevents breaking changes.

Optic looks at traffic and patches your OpenAPI file to keep it accurate and complete.

Optic tracks how your API changes over time and catches breaking changes in CI.

Optic detects and helps resolve any drift between your API and its documentation.

Raise your standards

Many API programs struggle to set high APIs standards, without getting in the way of developers. Today's API linters are noisy and will ask developers to make breaking changes. Optic has a smart API linter that is compatible with Spectral. Since Optic understands the history of your API, it can apply your latest standards to new APIs, and a different set of standards to your legacy APIs.
