In their own words
Happo
Happo checks interface changes with visual and accessibility regression testing. It captures screenshots of component variants in browsers; a snapshot is one variant in one browser, and a run usually occurs once per CI build. Accessibility testing is included on every plan. Framework options include Storybook, Playwright, Cypress, and a generic API. Repository integrations include GitHub, GitHub Enterprise, Bitbucket, Azure DevOps, and GitLab, though GitLab support is experimental. Its CLI detects CI providers such as GitHub Actions, CircleCI, Travis CI, and Azure DevOps. Available browsers vary by plan: the listed options are Chrome, Firefox, Safari, Microsoft Edge, and iOS Safari. The free plan includes 5,000 snapshots per month; once the quota is reached, the account pauses until the next cycle or an upgrade. Paid plans start at $149/mo, with additional snapshots charged on paid tiers. Happo began as a project in 2014, and its commercial product launched in 2017.
SmartUI
SmartUI captures application UI screenshots and compares them with baselines to identify visual regressions across browsers, devices, apps, and PDFs. Its Visual AI filters rendering noise and explains meaningful differences, while Smart Ignore can mask dynamic regions and distinguish layout shifts from other changes. Root Cause Analysis compares screenshot differences with code changes and suggests fixes. The listed frameworks include Selenium, Playwright, Puppeteer, Cypress, Appium, Espresso, XCUITest, and Jest. SmartUI describes coverage across 3,000+ browser combinations and 10,000+ real devices, and supports Figma-to-live-UI comparison and PDF checks for text, layout, font, and graphic differences. Git branch-aware baselines work across branches and CI/CD pipelines; diffs and suggestions can be exported to Jira or Slack, with GitHub and GitLab integrations listed. The free plan includes 2,000 screenshots for lifetime use and one month of build history. SmartUI Visual Regression costs $199 a month, billed annually, and includes one year of build history; screenshot volume is selected with the plan.
