abtop
Like htop, but for AI coding agents. Monitor Claude Code & Codex CLI
...It is read-only, so it does not require API keys or authentication and does not control the agents it observes. abtop is especially useful for developers running several agents across projects who need quick visibility into cost, quota pressure, context growth, and orphaned processes. Its main value is bringing operational observability to AI coding-agent workflows directly inside the terminal.
