The best open-source Lovable alternative is Dyad, a local desktop app that builds full-stack web apps with your own AI keys, followed by bolt.diy, the official open-source Bolt.new. Both are free to run, but you pay your AI provider and handle setup. For most people, our pick is Leanfinit: free during the beta, with no setup.
We checked each project's GitHub page in October 2026 for its license, star count and setup needs. Star counts change daily, so treat them as a rough signal. For hosted tools too, see our full guide to Lovable alternatives.
Is Lovable open source?
No. Lovable is a hosted commercial product. The code it generates is yours: it syncs to GitHub on every plan, but .zip download needs a paid plan (Lovable FAQ).
Lovable grew out of GPT Engineer, an MIT-licensed command-line code generator that calls itself the "Precursor to" lovable.dev. Its repository was archived on April 22, 2026 and is now read-only (GPT Engineer on GitHub).
Lovable's Trustpilot score is 4.2/5 across 1,767 reviews, yet negative reviews focus on fast credit use and billing problems, a big reason people look at open source

The best open-source Lovable alternatives, ranked
1Our pick: Leanfinit, free with no setup
Leanfinit is not an open-source project. We rank it first because it delivers what most people want from open source, a free tool and code they own, without API keys, terminals or Docker. It is completely free during the beta, with no paid plans and no credit card (Leanfinit).
Describe an app in plain words and get a working app in seconds. There are no servers, databases or hosting to set up or pay for. Publish with one button, rebuild by describing changes, and export the code: "Your data, your code."
2Dyad: the closest open-source Lovable alternative
Dyad describes itself on GitHub as a local, open-source AI app builder and an alternative to Lovable, v0, Replit and Bolt, with about 21.6K stars (Dyad on GitHub). You bring keys for Anthropic, OpenAI or Google, or run local models through Ollama, and connect Supabase or Neon for data (Dyad).
Code outside src/pro is Apache 2.0, while src/pro uses the Functional Source License 1.1. Pro ($20 a month) and Max ($79 a month) are optional.
3bolt.diy: the official open-source Bolt.new
bolt.diy calls itself "the official open source version of Bolt.new." It is MIT-licensed with about 19.9K stars and supports 19+ AI providers, plus local models through Ollama and LM Studio (bolt.diy on GitHub). You run it with Docker, Node.js or as an Electron desktop app.
Hosted Bolt.new scores 1.6/5 on Trustpilot across 203 reviews, with complaints about tokens burned on error fixes (source). Self-hosting moves that cost to your own AI bill.
4Open Lovable: rebuild a website as a React app
Open Lovable from Firecrawl promises to "Clone and recreate any website as a modern React app in seconds." It is MIT-licensed with about 28.6K stars (Open Lovable on GitHub). Setup needs three services: a Firecrawl key, an AI key and a code sandbox (Vercel or E2B).
5Onlook: visual editing for React apps
Onlook calls itself "The Cursor for Designers," with a Figma-like canvas for Next.js and Tailwind projects (Onlook on GitHub). It is Apache 2.0 with about 26.8K stars, and its hosted version was in early access.
6LlamaCoder: small apps from one prompt
LlamaCoder bills itself as "An open source Claude Artifacts." It is MIT-licensed with about 7.1K stars and needs a Together AI key and a Neon database to self-host (LlamaCoder on GitHub).
7OpenHands: an agent platform for developers
OpenHands is an MIT-licensed, self-hosted control center for coding agents, including Claude Code, Codex and Gemini (OpenHands on GitHub). It is closer to Cursor than to Lovable; see Lovable vs Cursor.
What open source really costs
"Free and open source" rarely means zero cost:
For a non-developer, that adds up. Compare predictable options in cheaper Lovable alternatives or start with free Lovable alternatives.
Why Leanfinit is the better Lovable alternative to open source
Free without the hidden bills. Leanfinit is completely free during the beta: no AI keys to pay for, no sandbox, no hosting.
Your code, without lock-in. Code export is available, while Lovable Free has no .zip download and Bubble has no code export at all (Bubble support).
Zero setup. No terminal, Docker or Node.js. Sign in with Apple or Google and describe your app.
More is coming. The Leanfinit mobile app is in development and will generate offline apps that run on your device.
