Open Lovable

Point Open Lovable at an existing website and it hands back a React or Next.js app written in TypeScript with Tailwind CSS.

Open Lovable is a free, MIT-licensed AI code generator and website builder that clones and converts sites, then lets you refine the result through an AI chat.

Generated code runs in an E2B Sandbox, and you can swap prompts, frameworks and AI models, including Claude, GPT and Groq.

The tool itself costs nothing and has no usage cap, and you can self-host it to keep your data.

The catch is that it needs your own API keys for E2B, Firecrawl and the AI models, and those services may charge beyond their free tiers.

Visual accuracy typically lands at 80 to 95 percent, so expect some cleanup.

Basic React knowledge helps, and sites with heavy backend logic need extra work.
