Sherlo

Visual regression testing for React Native, integrated with Storybook. Capture screenshots on iOS and Android simulators in the cloud, detect visual changes, and ship UI updates with confidence.

▶️ Sherlo in 2 minutes

How It Works

1. 📸 Capture - Sherlo takes screenshots of your UI on iOS and Android devices in the cloud
2. 🔍 Detect - All visual changes are automatically detected by comparison with previous versions
3. 👍 Review - Your team reviews detected changes before they go live

Key Benefits

• 🖼️ Pixel Perfection - Your designs, implemented exactly as intended
• ✅ Ship with Confidence - See exactly what changed before release - no surprises in production
• ⏱️ Minutes Not Hours - Forget device-by-device checks - every UI update caught automatically
• 🤝 Review Together - One place where devs, designers, PMs, and QA collaborate
• 📱 Real Mobile Testing - Native iOS & Android testing - not web approximations like React Native Web
• ☁️ Visual Testing Cloud - You build, we test - on infrastructure built specifically for mobile UI testing
