Summary

Happo is a visual and accessibility regression testing platform for checking interface changes. A snapshot is one screenshot of a component variant in one browser, and a run usually takes place once per CI build. Teams can connect Storybook, Playwright, Cypress, or a custom setup through the API. Repository integrations include GitHub, GitHub Enterprise, Bitbucket, Azure DevOps, and GitLab; GitLab support is marked experimental and includes self-managed instances. The Happo CLI can detect CI providers including GitHub Actions, CircleCI, Travis CI, and Azure DevOps. Listed browser coverage includes Chrome, Firefox, Safari, Microsoft Edge, and iOS Safari, though availability depends on plan. Accessibility testing is included on every plan. The free plan includes 5,000 snapshots per month and has no credit card or time limit; when its quota is reached, the account pauses until the next cycle or an upgrade. Paid plans start at $149 per month, and paid tiers charge for additional snapshots. Happo began as a project in 2014; its commercial product launched in 2017.

Who it is for
