Herdr
Teams that run more than one coding agent at a time — for example Claude Code and Codex working on separate tasks in parallel — typically end up with a pile of terminal tabs or tmux panes, one per agent. Keeping track of which agent is stuck waiting for input, which has finished, and which is still working becomes a manual, error-prone chore. herdr is a terminal application built specifically to solve this: it acts as a supervisor layer over multiple agent sessions, showing their status side by side in one interface instead of one plain terminal window per agent.
The tool is aimed at developers who have adopted agentic coding workflows and now juggle several concurrent agent sessions as a matter of course. Rather than replacing the agents themselves, it sits on top of them, giving a single place to launch, monitor, and switch between sessions.
herdr is written in Rust and has attracted substantial open-source traction: over 14,000 GitHub stars and more than 800 forks as of this assessment, with commits pushed within the last day, indicating active maintenance rather than an abandoned side project. It carries 45 open issues, a ratio consistent with a actively-used tool of this size rather than a sign of neglect.
The placement is Assess rather than Trial because the underlying need — supervising multiple concurrent coding agents from one terminal interface — is real and growing as agentic workflows spread, but the tool has not yet been used in the user's own production pipeline. The inner position reflects that the project's popularity and maintenance activity make it a strong first candidate to formally trial once a multi-agent workflow that would benefit from it exists.
