About

Bolt.diy is the community open-source version of Bolt.new, started by Cole Medin. It brings the same in-browser AI app-building experience — describe an app, watch the agent write the code, run it, and deploy — but you choose the language model for every prompt, from OpenAI and Anthropic to local models via Ollama.

The project is MIT-licensed on GitHub with an active contributor community and official docs covering local, Docker, and Cloudflare Pages deployment. The software itself is free; you pay only for your own LLM API usage, which makes it the cost-conscious alternative to hosted builders, at the price of setting up and hosting it yourself.

What it can do

  • In-browser AI agent that writes full-stack web apps from prompts
  • Choice of 19+ LLM providers per prompt, including local models
  • Live preview with run/edit/iterate loop
  • Supabase integration for backend features
  • One-click deploy to Netlify, Vercel, GitHub Pages
  • Docker and Cloudflare Pages self-hosting guides
  • MIT-licensed, community-maintained codebase

Setup

  1. Install Node.js (or Docker) on your machine.
  2. Clone the bolt.diy repository from GitHub.
  3. Install dependencies and start the app locally (see the official docs for OS-specific steps).
  4. Add your own LLM API key(s) in the settings (OpenAI, Anthropic, Ollama, OpenRouter, and others supported).
  5. Prompt the agent to build your app, preview it in the browser, and deploy to Netlify, Vercel, GitHub Pages, or Cloudflare Pages.

Prerequisites

Node.js or Docker; your own LLM provider API key(s) (or a local model via Ollama); a hosting target for deployment.

Trust score — 7/10

/10 trustVerified

Scored 7/10 (TIER verified, metrics-v1). Evidence: MIT-licensed open-source repo under coleam00 (bolt.new-any-llm, now bolt.diy) with documented 19+ LLM provider support and official docs at stackblitz-labs.github.io/bolt.diy; independent Medium comparison corroborates the feature and cost-model differences vs Bolt.new. Docs corroboration: README documents setup, provider configuration, and deployment paths. Strengths: fully open source (no lock-in); bring-your-own-model cost control; active community. Docked for: (1) requires meaningful technical setup (Node/Docker, API keys) — not no-code; (2) community project, so support and longevity depend on volunteer maintenance. License: MIT.
