Lovable

Description

Lovable is a hosted prompt-to-app product: users describe what they want, Lovable generates an editable codebase with frontend, backend, database, authentication, and integrations. Plan mode brainstorms and decides before code is written; Agent mode is the autonomous execution mode that applies changes directly, inspects logs and runtime, and iterates until issues are resolved. Projects sync bidirectionally with GitHub. Lovable Cloud is the built-in backend (database, auth, storage, edge functions) running on a Supabase open-source foundation. Lovable is positioned as the commercial successor to gpt-engineer.

Solution

Two-mode loop. Plan mode is a read-only brainstorming/decision surface — ask questions, debug, compare approaches — with no code changes. Once a plan is approved, Agent mode takes ownership end-to-end: applies file diffs, runs the app, inspects logs/runtime/network, iterates until resolved or clarification is needed. All changes flow through an editable code tree that can be synced to GitHub.

Primary use cases

• chat-driven full-stack app generation with editable code
• Plan-then-Agent execution loop with autonomous iteration
• GitHub-synced projects for downstream engineering workflows
• Lovable Cloud backend (Supabase) with database, auth, storage, edge functions
