herdr
CLITerminal multiplexer built for coding agents: run Claude Code, Codex and others in split panes, each marked working, blocked or idle, with sessions surviving disconnects. Agents can also create panes and message each other through the CLI.

the runtime your coding agents live on.
- detach without stopping work — herdr keeps terminals running in a background server when you close the client or lose your SSH connection. after a server or machine restart, herdr restores the saved layout and can resume supported agent sessions; the original processes do not survive. session state →
- several machines, one window — keep local work and saved ssh machines together, with a combined agent list and independent reconnects. remote machines →
- never hunt for the stuck one — every pane is marked working, blocked, or idle. when an agent stops and needs an answer, herdr says so.
- agent-native — agents drive herdr through the cli and socket api: they can spawn panes, prompt each other, and wait until another agent is genuinely blocked. agent skill →
- runs what you already run — claude code, codex, cursor, opencode, grok and the rest. herdr doesn't wrap or replace them; it owns their terminals. building an agent? add herdr support →
- keyboard and mouse, both first-class — tmux-style prefix keys and click, drag, split. pick per moment, not per tool.
- plugins — extend panes and workflows. browse the marketplace →
- one rust binary, no electron — runs in whatever terminal you already use.

Zellij
CLITerminal multiplexer written in Rust, an alternative to tmux, with layout files, floating and stacked panes, WebAssembly plugins and a built-in web client. Handy for running several agent sessions at once.

Codex CLI
CLIOpenAI's coding agent that runs locally, written in Rust: reads and writes code and runs commands inside an OS-level sandbox. Sign in with a ChatGPT plan or use an API key.

RTK (Rust Token Killer)
CLIRust CLI proxy that filters and compresses command output before it reaches the agent's context, covering git, tests, grep, ls and 100+ other commands and cutting bash output by up to about 90%. Hooks automatically rewrite commands run by Claude Code, Codex and others.

ripgrep
CLIFast regex search across directories (command rg) that respects .gitignore, skips hidden and binary files by default and filters by file type. A go-to command for coding agents searching a codebase.

tmux
CLITerminal multiplexer: run multiple sessions and panes in one terminal, with processes surviving disconnects. Agents use it to host long-running tasks and drive interactive programs, and many parallel multi-agent session tools build on it.
tmux/tmux49.9k
fd
CLISimple, fast alternative to find with intuitive syntax and regex and glob matching, skipping hidden and .gitignored paths by default. Can run commands on results in parallel; handy for agents locating files quickly.
