Build amazing APIs and collaborate at scale
Optic accurately documents your team's APIs, prevents breaking changes, and helps internal teams work together more effectively.
Verified Accurate API Documentation
Optic's open source tools check the accuracy of your OpenAPI specifications and makes it easy to share validated documentation with consumers.
Prevent Breaking Changes
Optic protects your consumers from breaking changes. Every month Optic stops thousands of breaking changes from reaching production.
Keep your specs up-to-date
Optic's CLI is like git for APIs. Instead of writing YAML, show Optic traffic, and it will accurately patch the OpenAPI for you. It is so easy developers use Optic to track API changes as they work.
Go API-firstAdopting OpenAPI and working API-first are good ideas but they have been hard to put into practice. Optic's tools make OpenAPI easier for developers to use so teams can start working API-first.
Get notified when internal APIs change
Subscribe to the APIs your team depends on, and get notified when they change. Most apps are built on dozens of APIs, Optic helps teams coordinate changes and work more effectively at scale.
API Change Review
Optic adds visual API changelogs to GitHub/GitLab Code so everyone on your team understands exactly what API changes are being considered. Breaking changes and changes that do not follow your team's style guide are flagged.
