README
Adopt OpenAPI. Start working API-first.
Optic's Open Source tools make OpenAPI and API-first practices easy for any team to adopt.
Installation
npm install -g @useoptic/optic
Diff OpenAPI specifications
Understand the API changes between two versions of an OpenAPI descriptions. Optic helps teams review proposed API changes:
diff current branch with base branch
optic diff openapi.yaml --base main
between two OpenAPI files
optic diff openapi.yaml openapi-changed.yaml
Catch breaking changes
API diffs containing breaking changes will be flagged so you do not break consumers. Optic helps you keep your promises.
optic diff openapi.yaml --base main --check
Read breaking change documentation
Easily adopt OpenAPI
Create new and update existing OpenAPI specifications straight from your services' traffic. Optic makes it easy to adopt OpenAPI in a day, without changing how you work.
Tracking changes with Optic:
Show Optic real API traffic using the oas capture
commands. Traffic can come from your development environment, tests, or the browser.
oas capture --proxy localhost:3000 traffic.har
Captured traffic is like working copy in Git. Use oas status
to see the difference between how your OpenAPI specification says your API works, and how it actually works.
oas openapi.yaml status --har traffic.har
Run oas add
and oas update
to update the spec. Optic precision patches your OpenAPI file with the same additions, updates, and removals you would manually write. This is faster and much less error-prone than writing OpenAPI by hand.
oas openapi.yaml add --har traffic.har GET /lists
oas openapi.yaml update --har traffic.har
A collaborator, not a generator
Using
oas
to update your spec is like working with a collaborator. It helps you write all the boilerplate OpenAPI and keep your spec in sync with the actual API's behavior.✅ Never overwrites changes developers make to the same OpenAPI file
✅ Respects $refs across multiple files
✅ Improves accuracy of your specification
✅ Speeds up your team
