Herdr
Ogulcan Celik
Herdr is a terminal-native agent multiplexer — every coding agent at a glance, real terminal views, detach and reattach anywhere without losing sessions.
Key features
- Agent Multiplexer: See every running coding agent at once with real terminal views — blocked, working, or done — instead of wrapped or interpreted output.
- Detach and Reattach Anywhere: Sessions survive restarts and can be reattached from any terminal or over SSH so long-running agents keep working in the background.
- Socket API for Agents: A pure socket API lets agents themselves spawn panes, read output, and wait on each other, with a documented agent-skill.
- Keyboard + Mouse First Class: tmux-style prefix keys plus click, drag, and split — pick whichever interaction fits the moment.
- Plugin Marketplace: Extend panes and workflows with plugins from the herdr.dev plugin marketplace.
- Single Rust Binary: Distributed as one Rust binary (no Electron), installable via curl script, Homebrew, or mise, with a Windows PowerShell beta.
Best for
- Coding Agent Fleet Management: Watch a swarm of Claude, Codex, or Cursor agents in one dashboard while they work on different repos.
- Long-Running Agent Jobs: Kick off multi-hour agent tasks, detach, and reattach from a laptop later to check status without losing progress.
- Remote Development: SSH into a workstation and reattach the exact multiplexer session, so agents keep running on the server between sessions.
- Agent-to-Agent Orchestration: Use the socket API so one agent can spawn sub-agents in new panes and wait on their output.
- Terminal-Centric Workflows: Replace ad-hoc tmux + shell tricks with a purpose-built multiplexer that understands agent lifecycles.

- Character + Message Scoring: 1 point per character and 10 per message — lowest total wins.
- Curated Rounds: Themed challenges like 'Hello World?', 'The Ultimate Answer', and 'The Jailbreak'.
- Constraint-Based Puzzles: Forbidden words and exact-output targets force creative prompting.
- Instant Feedback Loop: See the AI's reply and score after each attempt.
- No Signup Required: Play directly in the browser.
Best for
- Learning prompt engineering through hands-on practice
- Team building or icebreaker activity for AI-focused engineering teams
- Benchmarking your own prompt intuition against a scored objective
- Warm-up before designing production prompts or evals
- Teaching students the sensitivity of LLMs to phrasing
