Lovable
Lovable is an AI full-stack app builder from Lovable (lovable.dev) that turns natural-language prompts into production-ready apps with Supabase backends and GitHub sync. It's a web product - no CLI or VS Code extension - with chat, multi-file edit, and agent mode built in. Lovable is best paired with frontier coding models for complex multi-file refactors. Starter plans begin at $20/mo on a freemium tier.

Best LLMs for this agent
Lovable runs Claude Sonnet 4.6 by default for most app generation, and the model choice is managed inside Lovable rather than exposed as BYOK.
Claude Opus 4.6 is available for harder multi-file refactors where Lovable needs stronger planning and reasoning over the generated app.
Pricing and Provider Comparison
Hosted agents expose plan pricing. Bring-your-own-key agents pass the main cost through the model provider route you configure.
