What it is

A desktop app for macOS and Windows that builds full-stack JavaScript apps locally using your own OpenAI, Anthropic, Google or local model keys. Supabase integration covers database, auth and functions; deploy to GitHub, Vercel or your own cloud. Apache 2.0 apart from src/pro, with 21K+ GitHub stars.

Why it earns a slot

The zero-lock-in answer: no signup, no per-token platform markup, and your source and prompts never leave the machine. The obvious pick for client work under NDA, or for anyone tired of credit meters.

Know before you commit

You pay model providers directly, so a runaway agent loop hits your API bill with no platform-side cap. There is no hosted preview URL or built-in deploy target — you wire hosting yourself.

Getting started

Download the macOS or Windows build from dyad.sh; no account required.
