Lovable
AI full-stack app builder with built-in Supabase backend and GitHub sync
Lovable (formerly GPT Engineer) is an AI-powered platform that builds complete web applications from natural language descriptions. Unlike tools that only generate UI, Lovable creates the entire stack — frontend with React and Tailwind CSS, backend with Supabase for authentication and database, and automatic GitHub sync for version control. Describe your app, and Lovable delivers a working, deployable product with real user accounts and persistent data.
Visit LovableWhat is Lovable?
Lovable is an AI-powered full-stack application builder that evolved from the open-source GPT Engineer project. Originally launched in 2023 as an experiment in AI code generation, the team rebranded to Lovable in late 2024 as the product matured into a comprehensive app building platform. The core mission is simple but ambitious: let anyone describe a software application in natural language and get a working, production-ready product — complete with user authentication, database, and deployment — without writing a single line of code manually.
What distinguishes Lovable from other AI code generation tools is its deep integration with Supabase, the open-source Firebase alternative. When you describe an app that needs user accounts, data storage, real-time updates, or file uploads, Lovable automatically configures a Supabase project with the appropriate database schema, authentication flows, row-level security policies, and API endpoints. This means you get a genuine production backend — not just a frontend mockup — from a natural language description. The result is an app where users can actually sign up, log in, create data, and interact with persistent storage.
The development experience in Lovable is conversational and iterative. You start by describing your app in broad strokes — "build a project management tool with task boards, team members, and deadline tracking" — and Lovable generates an initial version. From there, you refine through follow-up prompts: "add a Kanban view," "make the sidebar collapsible," "add email notifications when a task is assigned." Each iteration updates the live preview and commits the changes to your GitHub repository, giving you full version control and the ability to revert changes if needed.
Lovable offers four pricing tiers to match different needs. The free tier provides limited monthly messages for experimentation and basic app creation. The Starter plan at $20/month unlocks Supabase integration and GitHub sync with more messages. The Launch plan at $50/month provides increased capacity and priority support for serious builders. The Scale plan at $100/month offers maximum message capacity and team features for organizations building multiple applications. All generated code is standard React, TypeScript, and Tailwind CSS — fully portable and not locked into Lovable's platform.

Frequently Asked Questions
What is Lovable?
Lovable (formerly known as GPT Engineer) is an AI-powered full-stack application builder that creates complete web applications from natural language descriptions. You describe what you want to build in plain English, and Lovable generates a working application with a React/TypeScript frontend, Supabase backend for authentication and database, and automatic GitHub synchronization for version control. It's designed to make software development accessible to everyone, from non-programmers building their first app to experienced developers who want to prototype faster.
Is Lovable free to use?
Yes, Lovable offers a free tier with a limited number of monthly messages for experimentation and basic app creation. Paid plans start at $20/month (Starter) with more messages and full Supabase integration, $50/month (Launch) with increased limits and priority support, and $100/month (Scale) with maximum capacity and team features. The free tier is enough to explore the platform and build simple apps, but serious projects typically require a paid plan for the additional message capacity.
What happened to GPT Engineer?
GPT Engineer rebranded to Lovable in late 2024. The project started as an open-source experiment in AI code generation and evolved into a full commercial platform for building complete web applications. The rebrand reflected the product's expanded scope — from generating code snippets to building entire applications with backend integration, authentication, and deployment. The core team, technology, and mission remained the same; the new name better represented the product's goal of making software development lovable for everyone.
How does Lovable integrate with Supabase?
Lovable has a deep, built-in integration with Supabase that automatically handles backend configuration. When you describe an app needing user accounts, Lovable sets up Supabase Auth with email/password and social login. When you need data storage, it creates appropriate database tables with row-level security policies. It also configures real-time subscriptions, file storage, and edge functions as needed. The integration is seamless — you describe what your app should do, and Lovable handles the entire Supabase setup automatically.
Can I export code from Lovable?
