Move fast, break nothing

Your business is built on a foundation of APIs. Optic helps you document all of them and prevent breaking changes so that everything can ship faster.

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.
Kostas Petrakis Lead API Engineer

Your team's API toolkit

Don't build your own OpenAPI tooling. Optic fills in the gaps and makes OpenAPI usable by developers and their teams. We have built-in support for generating specs, testing implementations, API governance, and lifecycle management.

We are set up to provide a great API and an amazing developer experience to our consumers. Realizing the promise of OpenAPI has always been hard. Optic's tools made it easier to get developers on-board and start fulfilling the promises of working API-first.
