Herdr
Herdr is a terminal-native multiplexer built specifically for running multiple AI coding agents at once — Claude Code, Codex, Cursor, and a dozen others — each in its own real PTY pane with automatic blocked/working/done/idle status, so a developer stops tabbing through terminals to find out which agent needs them.
Ogulcan Celik shipped v0.1.0 on March 27, 2026 as a small Rust binary, and by June 29 its Hacker News launch drew 164 points and 105 comments, pushing the ~10MB tool past 10,000 GitHub stars, to #1 trending on GitHub, and toward a fast-forming third-party plugin ecosystem within three months.
Think of it as tmux that actually knows which of your agents is stuck versus which one just finished.

Why is it emerging now?
Herdr crossed 10,000 GitHub stars and hit #1 trending after a 164-point, 105-comment Hacker News launch on June 29, 2026, as developers juggling Claude Code, Codex, and Cursor sessions in parallel started wanting a dedicated agent-state dashboard instead of plain tmux.
Outlook
6-month signal projection and commercial timeline.
Agent-state terminal multiplexing fills a real daily-driver gap for devs running parallel coding agents, and plugins are already shipping around it.
Risk · tmux/Zellij loyalists and GUI rivals like conductor.build and cmux crowd the same niche; no public security audit yet.

Herdr's sidebar doesn't just split panes — it tells you which of your six AI agents is stuck, and that turned tmux loyalists into converts inside a single 105-comment thread.
A three-month-old Rust binary just out-argued tmux on Hacker News — not on speed, but on knowing which of your agents is actually stuck.
Most terminal setups melt past four parallel agents — here's the one that didn't, and why its sidebar matters more than its speed.
