Happo is a visual and accessibility regression testing platform for checking interface changes. A snapshot captures one component variant in one browser, and a Happo 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 CLI can detect CI providers such as GitHub Actions, CircleCI, Travis CI and Azure DevOps. Listed browser coverage includes Chrome, Firefox, Safari, Microsoft Edge and iOS Safari, with availability varying by plan. Accessibility testing is included on every plan. The free plan includes 5,000 snapshots per month and no credit card or time limit, but an account pauses when it reaches quota until the next cycle or an upgrade. Paid plans start at 149.00 USD per month, with charges for additional snapshots. Happo says data is encrypted in transit and at rest and customer screenshots are treated as confidential with account-level access controls.
