What is gritz?

gritz is an orchestrator for coding agents. It runs agents such as Claude Code, Codex, Cursor and Copilot in parallel, each in its own sandbox, and keeps track of their work in one place.

  • Tasks are the unit of work. A task gives an agent its instructions and runs it in a sandbox built from a workspace: the image, repositories, agent and MCP servers it needs.
  • Runners start the sandboxes, on Docker or Lambda MicroVMs, and stream each agent’s log back to the gritz server, where the Web UI shows it live.
  • Events keep a task going after its first run. When an agent opens a pull request or comments on an issue, it links the resource to its task, and a review comment on that pull request wakes the task up with the new event.

Agents and users drive gritz the same way: from the Web UI, the gritz CLI, or any MCP client.
