FlyCode (YC S22) makes React web apps editable in minutes so Product and UX teams can iterate and release products faster, so they don't have to wait on (or consume) developer time.

Saves development time
No code integration, it just reads your code!
GitHub based, a bot is scanning the code and creates pull requests
Use your own stack and components
Retain codebase ownership
