Lovable

Lovable (formerly known as GPT Engineer) is an AI-powered full-stack web app builder that takes a natural language prompt and produces a complete, deployable application — React + Tailwind CSS frontend, Supabase backend with PostgreSQL database, authentication, file storage, and real-time capabilities — without requiring any coding experience.

The Supabase integration is Lovable's most significant differentiator in the AI builder category. When you describe an app that needs user accounts, data persistence, or file uploads, Lovable automatically provisions a Supabase project, generates the database schema, sets up row-level security policies, and wires up the authentication flow. The result is a genuinely production-capable backend, not a mock or placeholder.

Stripe integration allows adding payment processing and subscription models to generated apps directly from within Lovable, making it practical for launching SaaS products and paid services without code.

GitHub sync connects every Lovable project to a GitHub repository, enabling developers to clone the generated codebase, make manual edits in their own IDE, and push changes back — creating a hybrid AI-generation + manual coding workflow. Lovable reads commits from GitHub and incorporates them into its context.

Dev Mode (available to paid users) is a code-first editing layer directly within the Lovable interface — inspect the underlying React/TypeScript source, make targeted edits, and have Lovable understand and build on those changes in subsequent prompts.

Visual editing provides a floating combo-box interface for pixel-perfect tweaks — adjusting colors, spacing, fonts, and layout without writing CSS or prompting the AI.

Lovable hit $75M ARR with 2.3M monthly active users in mid-2025 and raised a $200M Series A at a $1.8B valuation, making it one of the fastest-growing AI builder products. The platform supports mobile-responsive output and includes a mobile-native builder for creating apps from a phone.
