Optic is dead. A 2026 migration guide for OpenAPI breaking changes
Optic, a tool for OpenAPI breaking-change detection, has been officially discontinued as of January 2026. Originally acquired by Atlassian in 2024, it failed to integrate into Atlassian Compass and has since been abandoned without support or updates. Users are encouraged to migrate to alternative tools like SpecShield or oasdiff for their OpenAPI needs.
- ▪Optic's GitHub repository was archived on January 12, 2026, marking its discontinuation.
- ▪The tool was acquired by Atlassian in April 2024 but was never integrated into Atlassian Compass.
- ▪Users who relied on Optic for spec-to-spec diffing can easily migrate to alternatives, while those using it for OpenAPI generation will need to change their workflow.
