About

Cezar is an open-source orchestrator that runs Claude Code, Codex, OpenCode, Pi and other coding agents in parallel, with each task in its own git worktree and extra tasks queued. It runs locally or on a VPS, has an Autonomous mode that does not stop to ask, and defines multi-step workflows as YAML graphs of agents, checks and gates. It can launch tasks from Jira, Linear and GitHub issues and stores its state as plain files with no database.

Use cases: coding, agent-orchestration, workflow-automation
