What it does

GreatCTO runs a coding agent as a pipeline—architecture, data model, backend, frontend, tests, and deploy—with a second model checking each stage. Three decisions stay yours: what gets built, how, and whether it ships. It is MIT-licensed, runs locally with no signup, and requires Claude Code or Codex for the skills and MCP server.

Evidence

Each bar is one request to the project's own site

This one is installed and run on your own machine, so what we re-check is the project’s site — whether it is still published and still reachable. We cannot tell you from here that the tool itself runs.
