# Open-source alternatives to Bolt.new

> Open-source alternatives to Bolt.new that run locally, allow commercial use and need no paid API include sandboxd (build a full-stack web app from a chat prompt and run and preview the app in the browser (WebContainers); MIT; runs on CPU). None of the 8 projects we track covers all 6 Bolt.new jobs, so most people combine two or more.

Bolt.new: StackBlitz's hosted AI app builder. You prompt it in the browser and it writes, installs and runs a full-stack JavaScript app in an in-browser WebContainer, with hosting, a database, Expo mobile apps and Figma import. Usage is metered in tokens on paid plans. Pricing: See pricing page (checked 2026-10-15). Facts checked 2026-10-16.

## Projects

| Project | Jobs | Runs locally | Commercial use | Paid services | Hardware |
|---|---|---|---|---|---|
| [Screenshot to Code](https://repoquarry.dev/projects/screenshot-to-code) | design-to-app | Yes, backend and frontend run on your machine (or Docker); models are cloud APIs | Yes, MIT | Normally needs an OpenAI, Anthropic or Gemini key (Replicate recommended); Ollama is possible but not recommended | Not documented |
| [Dyad](https://repoquarry.dev/projects/dyad) | prompt-to-web-app, live-app-preview, app-backend-setup | Yes, desktop app; your app code stays in a folder on your computer | Core is Apache-2.0; the src/pro folder is under FSL-1.1, which restricts competing commercial use | Not required with local models (Ollama, LM Studio) or free API tiers; cloud model APIs and Dyad Pro are optional | Any machine that can run Node.js; local models need much more, and the docs suggest cloud models on weaker machines |
| [bolt.diy](https://repoquarry.dev/projects/bolt-diy) | prompt-to-web-app, live-app-preview, app-backend-setup, one-click-app-publish, mobile-app-from-prompt | Yes, local dev server, Docker or Electron desktop app | MIT code, but the WebContainers API it relies on has separate commercial terms for enterprise deployment | Not required with local models (Ollama, LM Studio); cloud model APIs and hosting accounts are optional | Not documented beyond Node.js 22.12+ and pnpm |
| [Chef](https://repoquarry.dev/projects/chef) | prompt-to-web-app, live-app-preview, app-backend-setup | The Chef UI runs locally, but it provisions projects through Convex's hosted control plane | Yes, Apache-2.0; production forks must replace Convex's internal authentication setup | A cloud model API key (Anthropic, Google, OpenAI or xAI) and a Convex account are required | Not documented |
| [sandboxd](https://repoquarry.dev/projects/sandboxd) | prompt-to-web-app, live-app-preview | Yes, self-hosted on your own Linux server or machine with Docker | Yes, MIT | None required; the default OpenCode agent uses OpenCode Zen's free hosted models. Paid model keys and sandboxd Cloud are optional | A Linux server with Docker; 2 vCPU and 4 GB RAM to start; amd64 or arm64 |
| [Onlook](https://repoquarry.dev/projects/onlook) | prompt-to-web-app, live-app-preview, visual-ui-editing, one-click-app-publish | The editor and its Supabase backend can be self-hosted, but user apps run in CodeSandbox's cloud | Yes, Apache-2.0 | CodeSandbox (hosts user apps) and OpenRouter (AI chat) API keys are required; local models not documented | Not documented |
| [Fragments](https://repoquarry.dev/projects/fragments) | prompt-to-web-app, live-app-preview | The web app runs on your machine, but generated code runs in E2B's cloud sandboxes | Yes, Apache-2.0 | An E2B API key (hosted sandbox service) is required; the LLM can be local via Ollama | Not documented |
| [Claudable](https://repoquarry.dev/projects/claudable) | prompt-to-web-app, live-app-preview, app-backend-setup, one-click-app-publish | Yes, Node.js app on your machine (Electron build optional) | Yes, MIT; agent CLIs and models follow their own terms | Needs a logged-in agent CLI; most are paid plans (Claude, ChatGPT, Cursor, Z.AI), but Qwen Code is listed as free | Not documented |

## Common questions

### Is there a free, open-source alternative to Bolt.new?

Yes. bolt.diy, Dyad, Claudable, sandboxd and Screenshot to Code are free to download and run on your own computer without paid API keys. Each covers only part of what Bolt.new does, so check which job you need.

### Can I do build a full-stack web app from a chat prompt locally without a Bolt.new subscription?

Yes, with Dyad (Apache-2.0), sandboxd (MIT) and bolt.diy (MIT). Check the hardware notes and licence conditions on each page before you start.

### Can I do run and preview the app in the browser (WebContainers) locally without a Bolt.new subscription?

Yes, with Dyad (Apache-2.0), sandboxd (MIT) and bolt.diy (MIT). Check the hardware notes and licence conditions on each page before you start.

### Which Bolt.new alternatives can I use commercially?

Confirmed: Chef, Claudable, Fragments, Onlook, sandboxd and Screenshot to Code. With conditions: bolt.diy and Dyad. This is not legal advice; read each licence.

### Does any open-source project replace all of Bolt.new?

Not as of 2026-10-16. Build a full-stack web app from a chat prompt, run and preview the app in the browser (WebContainers), add a database and login (Bolt Database / Supabase), publish the app to a live URL (Bolt hosting / Netlify), build a mobile app from a prompt (Expo) and turn a screenshot or design into an app (image or Figma import) are covered by different projects.
