A React Native library that provides fast, low-overhead multithreading via JSI, letting developers offload blocking JavaScript calls or expensive calculations to separate threads. It is explicitly a proof of concept and not intended for production use.

Use cases

• run blocking JS calls off the main React Native thread
• offload expensive calculations to a background thread in React Native
• avoid UI freezes from slow JSI calls like storage or SQLite operations
• run JavaScript functions on a separate thread with low overhead
• compute CPU-heavy tasks like Fibonacci in React Native without blocking the JS thread

When to choose

• you are experimenting with JSI-based threading in React Native
• you need to prototype offloading blocking JS work to another thread
• you want a lightweight alternative to native module bridges for background work

When to avoid

• you need a production-ready solution - the README explicitly warns against production use
• you need camera frame processing - use react-native-vision-camera frame processors instead
• you need long-term maintenance or broad React Native version support
• you want to avoid manual native file edits during setup
