termcast — Build TUIs with a Raycast-like React API

termcast is a framework for building terminal user interfaces using React. It implements the Raycast extension API (@raycast/api) but renders to the terminal via opentui. If you know Raycast, you know termcast.

bun install -g termcast
termcast new my-extension    # scaffold
cd my-extension && termcast dev   # hot-reload dev mode

IMPORTANT: before starting every task ALWAYS read opentui docs:
