Single binary in your existing terminal (Ghostty/Alacritty/Kitty/WezTerm/tmux). Detects Claude Code, Codex, Pi, OpenCode, Droid, Amp, and more. Agents spawn panes, prompt peers, and wait on real blocked state via CLI/socket. Multi-machine window, plugins marketplace, brew/curl install. Docs at herdr.dev/docs.","theCatch":"Vs Thurbox / Zellij / ECC: Thurbox is a lighter MIT tmux TUI orchestrator; Zellij is a general multiplexer; ECC is skills/memory/security on host agents — Herdr’s catch is agent-aware runtime + socket API, not another bare multiplexer and not an ecosystem pack. Agent state heuristics vary by harness; after machine restart, layout restores but original processes do not survive.","verdict":"Apache agent-terminal runtime when you herd many CLIs and need blocked/idle signals — not Thurbox-lite tmux, not Zellij alone.","addedAt":"2026-09-30","featured":false,"domain":"AI Agents","subSpecialty":"Orchestration","subcategory":"Orchestration","tags":["api","self-host","permissive","coding-agents","active","fast-stars"],"capabilities":["terminal","multiplexer","agents"],"surfaces":["API","Self-host"],"ecosystem":["Rust","Multi-platform"],"licenseModel":"Apache-2.0","githubStars":44680,"starsPerWeek":1514,"access":"free","archived":false,"repo":{"createdAt":"2026-03-27","pushedAt":"2026-10-18","license":"Apache-2.0","archived":false,"checkedAt":"2026-10-19"}},"related":[{"slug":"claude-code","name":"Claude Code","tagline":"Terminal-first coding agent with deep repository context"},{"slug":"cursor","name":"Cursor","tagline":"The AI-first code editor that understands your codebase"},{"slug":"devin","name":"Devin","tagline":"Autonomous AI engineer for defined engineering tasks"},{"slug":"stagehand","name":"Stagehand","tagline":"AI-native browser automation that mixes code and natural language"},{"slug":"browser-use","name":"Browser Use","tagline":"Open-source framework for LLM-driven browser agents"}],"links":{"self":"/api/gems/herdr","html":"/gems/herdr","markdown":"/gems/herdr.md","category":"/api/gems?category=agents","categoryPage":"/stacks/agents"}}
