Welcome to Limelight

Limelight is a powerful debugging tool designed specifically for React Native applications. Debug your React Native app like a web app — see exactly what’s happening, when it’s happening, and why.

​
Why Limelight?

React Native debugging has been extremely painful compared to web development. Limelight fixes that with:
  • Zero Config Setup — Add one line of code and start debugging immediately
  • Privacy-First — Desktop app keeps all debugging data local to your machine
  • Re-render Tracking — Identify unnecessary component re-renders that slow screens and cause bugs
  • Network Monitoring — Inspect all fetch and XHR requests in real time
  • Console Integration — Capture, filter, and search console logs with full context
  • React Native Optimized — Built specifically for mobile debugging workflows
  • GraphQL Intelligence — Automatic complexity scoring, query analysis, and performance insights. Works out of the box with Apollo, Relay, and custom GraphQL clients_
Built by a React Native developer frustrated with existing debugging tools.

​
Key Features
