Basalt turns your running Expo app into a clickable canvas inside VS Code or Cursor. Move text, resize views, tweak styles — real files, not a throwaway mock.
Free during beta · Expo / React Native · Not Flutter
Edit on the canvas → source updates in place
Built for React Native & Expo · Works in VS Code & Cursor
How it works
01
Click anything in your running app — text, a card, an image — the same as you'd click it in a design tool.
02
Drag it where you want, resize it, change color or spacing, right on the canvas.
03
Basalt edits your real source file in place — formatting and structure intact.
See it in action
Click any element in your running app and change its text, size, position, or style — directly on the canvas.
Hover any element to see exactly which component and source line it maps to, before you touch anything.
