Lovable (formerly GPT Engineer) is the world's first AI Full Stack Engineer, enabling developers and non-developers alike to build software products using only a chat interface. The platform evolved from the wildly successful open-source gpt-engineer project that became the fastest-growing code repository on GitHub with over 50,000 stars. In 2024, the commercial platform was rebranded from gptengineer.app to Lovable to avoid confusion and better represent the broader mission of creating software that creates other software. Lovable generates real, working code with functional frontends, backends, and database logic within minutes. The platform uses React, Tailwind CSS, and Vite for front-end development, with native Supabase integration for backend database management and authentication. Users can manage both UI and database through the same chat interface, with Supabase providing real-time features, authentication systems supporting multiple providers, and edge functions for custom backend logic. The platform's GitHub integration is particularly powerful – every change in your Lovable app is backed up in a Git repository in real-time, providing complete version history, team collaboration capabilities, and the freedom to host or deploy your app outside of Lovable. Users can import designs from Figma, connect to OpenAPI backends, and deploy with one click. Lovable offers custom domain support, role-based workspace access, and private project capabilities on paid plans. With a 4.9/5 rating from 151 users on Product Hunt, Lovable earns strong praise for rapid prototyping and polished UIs, with many non-developers shipping MVPs quickly. However, users note reliability issues at scale, with problems including infinite loops when fixing bugs, unexpected overwrites, slow edits, and costly credit consumption. The platform is excellent for demos, landing pages, and early MVPs, but less reliable for complex production applications today.
