GPT Engineer alternatives

One of the original 'agent writes a whole codebase from a prompt' CLI experiments; precursor to the commercial Lovable (lovable.dev / gptengineer.app). Repository archived (read-only) on 2026-04-22. Full GPT Engineer record →

Official migration path

gpt-engineer was archived read-only on 2026-04-22; its README points managed-service users to gptengineer.app (Lovable) and CLI users to aider.

Move to: Lovable (gptengineer.app) or Aider

  1. For a managed service, move to gptengineer.app, which the README calls the opinionated, managed evolution (repo About says precursor to lovable.dev)
  2. For a maintained hackable CLI, install aider with python -m pip install aider-install then aider-install
  3. Run aider from your project directory, e.g. aider --model sonnet --api-key anthropic=<key>
