What does Optic do for me?

Optic helps automate important tasks throughout the API Lifecycle

Documentation & Testing

Optic is the developer friendly way to document your APIs. After you add Optic to an API, the tool takes responsibility for:

  • Writing an accurate OpenAPI specification
  • Updating the specification when the API changes
  • Detecting when the API is not following its contract
  • Writing an API changelog and sharing it with your team
