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.
