Comps

tmux · github.com · Herdr is described as a competitor to tmux tailored for coding agents, using the same client-server PTY model but adding agent status states.[3][8]

Claude Code · anthropic.com · Herdr does not replace agents like Claude Code; it hosts them, so a developer choosing how to run Claude Code across projects weighs Herdr against the agent's own terminal workflow.[3][10]

Codex · openai.com · Codex is one of the agents Herdr is built to host and coordinate, so the same buyer decides whether to run it bare or inside Herdr.[10][13]
