The short version

If you like Lovable but not the credit limits (5 build credits a day, up to 30 a month on Free, then Pro from $25/mo), these open-source tools give you the same chat-to-app loop for the price of your model usage. Dyad is the closest match: a desktop app that builds full-stack web apps on your computer. bolt.diy is the open-source version of Bolt with any model you like. Open Lovable is Firecrawl’s example app for turning an existing website into a React app. When you outgrow app builders, OpenCode, Kilo Code and Cline are open-source coding agents that work on a real repository.

Dyad: the closest open-source Lovable

Dyad (78) is a free desktop app for macOS, Windows and Linux (Apache 2.0 outside its Pro folder, about 22k GitHub stars). It builds full-stack apps on your machine with your own API keys, local models or a ChatGPT subscription, and connects to Supabase, Neon and GitHub. It is free forever with your own key (Basic Agent, 20 messages a day); Dyad Pro is $20/mo with 200 AI credits if you’d rather not manage keys.

bolt.diy: Bolt, self-hosted, with any model

bolt.diy (74) is the official open-source (MIT) version of Bolt from StackBlitz Labs, with about 20k GitHub stars and a v1.0.1 release on Oct 12, 2026. It runs a full Node.js workspace in the browser with an editor, terminal and live preview, and lets you pick from 22+ model providers per prompt, including local Ollama and LM Studio. Run it from source (Node.js 22.12+ and pnpm), with Docker or as a desktop app, then push to Git or deploy to Netlify, Vercel or GitHub Pages.

Open Lovable: rebuild any website as a React app

Open Lovable (63) is an MIT-licensed example app from the Firecrawl team, with about 28.7k GitHub stars. Chat to build a React app, or give it a URL and it recreates the site in React. You run it yourself and need three keys first: Firecrawl (the Free plan gives 1,000 credits a month, no card), a model provider (Gemini, Anthropic, OpenAI or Groq) and a code sandbox (Vercel Sandbox or E2B). It has no hosting, database or sign-in built in, so treat it as a fast starting point rather than a full Lovable replacement.

Ready for real code: open-source coding agents

Once your app lives in a GitHub repo (Lovable can sync there too), an open-source coding agent can keep building it with any model. OpenCode (87, MIT, about 215k stars) works in the terminal, desktop and IDE and includes free models. Kilo Code (83, MIT) runs in VS Code, JetBrains and the CLI with an Auto Free option for free models. Cline (81, Apache 2.0) is a VS Code agent where you bring your own keys. All three are free; you pay only for inference.

What open source doesn’t give you

Lovable bundles hosting, a database (Lovable Cloud), sign-in and a one-click publish. With the open-source tools you set those up yourself: host on Vercel, Netlify, Cloudflare or a server running Coolify, and add Supabase, Neon or Nhost for data and auth. Model costs move to your own provider bill, which can be cheaper or pricier than Lovable credits depending on the model and how much you build.

How are these tools ranked?
Each tool is scored out of 100 on fit, vibe-coder friendliness, output quality, pricing, ecosystem, momentum and code ownership, using desk research of official docs and pricing pages. Affiliate status never affects scores.
Is there an open-source version of Lovable?
Lovable itself is not open source. The closest open-source alternatives are Dyad, a free desktop app builder, and bolt.diy, the open-source version of Bolt. Firecrawl’s Open Lovable is an MIT example app that builds React apps from chat or from an existing website.
What is the best free Lovable alternative?
Dyad scores highest among open-source app builders at 78: it is free with your own API key or a local model and keeps the code on your computer. Among hosted builders with free plans, Bolt (1M tokens a month) and Replit are the usual picks.
Is bolt.diy the same as Bolt.new?
No. Bolt.new is StackBlitz’s hosted product with plans (Free 1M tokens a month, Pro $25/mo). bolt.diy is the official open-source (MIT) version you run yourself with any model provider, including local models, and you handle hosting.
Can I run a Lovable alternative with a local model?
Yes. Dyad and bolt.diy both work with local models through Ollama or LM Studio, so the app builder costs nothing to run. Expect weaker results than top cloud models on bigger apps.
Do I need to code to use these?
Dyad and bolt.diy are chat-first like Lovable, but you install them and paste in a model key. Open Lovable and the coding agents (OpenCode, Kilo Code, Cline) assume you’re comfortable with a terminal or code editor.
