Bolt.diy
Open-source fork of Bolt.new supporting any LLM including local Ollama models, with 40k+ GitHub stars and no vendor lock-in for full-stack app generation.
Bolt.diy is a community-maintained open-source fork of StackBlitz's Bolt.new that removes the requirement to use StackBlitz's LLM backend, letting developers bring their own API key from OpenAI, Anthropic, Groq, OpenRouter, or any Ollama-hosted local model. It provides the same browser-based full-stack code generation experience - including a live preview, in-browser terminal, and npm package management - while allowing complete model flexibility. The project attracted 40,000+ GitHub stars within weeks of launch in December 2024, driven by demand from developers who wanted local or self-hosted model support for privacy-sensitive codebases. Teams can also self-host the entire Bolt.diy environment via Docker for air-gapped or enterprise deployments.
Key Features
- Browser-based full-stack app generation from natural language prompts with live preview
- Support for 20+ LLM providers including OpenAI, Anthropic, Groq, and OpenRouter
- Local model support via Ollama for completely private full-stack code generation
- In-browser terminal, package manager, and file explorer in a single unified workspace

- Self-hostable via Docker for air-gapped deployments and enterprise use cases
Use Cases
- Developers wanting Bolt.new functionality with their preferred LLM without StackBlitz lock-in
