Optic is one of 10 APIs that [API Linting](https://apis.io/providers/linting/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include API Diff, API Linting, Breaking Changes, OpenAPI, and TypeScript. The published artifact set on APIs.io includes API documentation, a GitHub repository, and release notes.

Optic catches breaking changes and applies lint rules to OpenAPI specs, generating OpenAPI from real traffic and keeping it accurate with automatic schema testing and patches. The project was archived in January 2026 after Optic Labs was acquired by Atlassian, but the ruleset model remains in active use via sweater-comb and forks.
