Framework Comparison

The only framework that checks every box

TypeScript compiled to native code. Real platform widgets. No runtime overhead.

Framework	Language	Native Code	Native Widgets	Runtime Overhead
Perry	TypeScript	✓ Native compiled	✓ Real platform widgets	✓ Zero runtime overhead
React Native	JS / TS	JS bridge	Partial	JS engine + bridge
Flutter	Dart	AOT	No shared UI	Dart VM
Electron	JS / TS	Chromium runtime	HTML mimics	Chromium + Node

Write TypeScript, Ship Native

Use familiar TypeScript syntax and APIs. Perry handles the rest.
