Sherlo is a visual regression testing tool built specifically for React Native. On every build it renders your app on real iOS and Android simulators in the cloud - native rendering, not React Native Web - screenshots every screen, and compares each against the previous version pixel by pixel....

As answered by people managing Codegres.org and Sherlo.
Sherlo's answer:
Sherlo is the visual regression testing tool built specifically for React Native. It renders your app on real iOS and Android simulators in the cloud - native rendering, not React Native Web - and diffs every screen pixel by pixel. Web-first tools like Percy, Chromatic, and Applitools can't test how a React Native app actually looks on a device; Sherlo does.
Sherlo's answer:
Because it's the React Native specialist. Percy, Applitools, and Chromatic are multi-platform generalists that test web-framework Storybook in a browser, not native iOS/Android rendering. Sherlo runs your app on real iOS and Android simulators, covers both platforms in one run, plugs into CI, and includes the cloud simulators from a free plan - no device farm, no credit card.
Sherlo's answer:
React Native teams that ship UI frequently - developers, designers, PMs, and QA who want to catch visual regressions before release. It fits teams already using Storybook and anyone shipping to many devices, themes, and languages who can't check them all by hand.
Sherlo's answer:
Sherlo was built by React Native developers who kept shipping UI bugs that slipped past functional tests and were painful to catch by hand across devices. Existing tools were web-first and didn't test native mobile rendering - so they built the visual testing tool they wanted for React Native.
Sherlo's answer:
React Native, TypeScript, an open-source SDK/CLI (github.com/sherlo-io/sherlo), cloud-hosted iOS and Android simulators, and a web app for reviewing diffs. Integrates with Storybook and any CI pipeline.
