About Dyad

Dyad is an open-source AI app builder that runs on your own machine rather than in a hosted sandbox. You bring your own model API keys, the generated code sits in a local folder you fully control, and there is no per-message credit meter on the free tier. A paid Pro plan adds bundled AI credits, Turbo Edits and Smart Context for larger codebases.

Key Features

Runs entirely locally — no cloud sandbox
Bring your own model keys (Anthropic, OpenAI, Google, local)
Full React + TypeScript codebase on disk
Supabase integration for auth and database
Open source under an permissive licence
Pro mode with Smart Context for large projects

Pros & Cons

Pros

Genuinely free at the core with no message caps
Your code and keys never leave your machine
Open source, so the project cannot rug-pull you

Cons

You manage your own model spend
No hosted preview URL — you deploy it yourself
Smaller ecosystem and fewer templates than Lovable or Bolt

Our verdict

The privacy-and-control pick. If bring-your-own-key and local files matter more than one-click hosting, Dyad is the obvious choice.
