bolt.diy takes StackBlitz’s Bolt.new — an AI app builder that runs a full dev environment in the browser via WebContainers — and opens it up so anyone can plug in their own model, including local or open-weight ones, instead of being locked to a single provider.

Why it stands out

Provider-agnostic, letting you swap in Claude, GPT, local models, or others rather than one fixed backend.
In-browser full dev environment, inherited from Bolt.new’s WebContainer approach — no local setup needed to run the generated app.
Actively maintained community fork, with contributions extending the original Bolt.new feature set.

Good for

Developers who want Bolt.new’s in-browser app-building workflow with control over which model powers it.
