tmux or Hive for Claude Code and Codex?
An honest comparison of tmux and Hive for running AI coding agents: what tmux does well, what Hive adds, and when to use which (or both).
Most people who run Claude Code or Codex for long stretches end up in tmux, and for good reason. Hive borrows tmux's core idea and adds what agents need. Here is how they compare, and when to use which.
What tmux does well
- It is everywhere. Installed or one package away on nearly every server you will ever SSH into.
- Sessions survive. A server process owns the terminals, so closing the window or losing the connection doesn't kill your agent.
- It is endlessly scriptable. Decades of configs, plugins and scripts.
- It is general. Editors, logs, REPLs: tmux doesn't care what runs inside.
If you already live in tmux and run one or two agents, it may be all you need.
Where agents strain tmux
tmux treats every pane the same, so it can't tell you what an agent is doing. With several agents across projects the questions become: which one is waiting for me, which finished, and are two of them editing the same files? You can build answers with hooks and scripts; tmux doesn't ship them.
What Hive adds
| Need | tmux | Hive |
|---|---|---|
| Sessions survive closing the terminal | Yes | Yes |
| Agent status: working, needs input, done | Build it yourself | Built in, for 20+ agents |
| Every agent across projects in one list | Build it yourself | Built in |
| Group work by repository | Sessions, by hand | Spaces that follow your cd |
| Agent in its own git worktree | Scripts | One key |
| Warning when agents share a directory | No | Yes |
| Mouse menus, clickable sidebar and tabs | Partly | Yes |
| Native Windows | No (WSL) | Yes |
Hive also has optional integrations that tmux users usually script: lazygit review beside the agent, GitHub PR checks, project tasks, desktop notifications, an Obsidian journal of agent activity, git status per project and token usage.
Keys feel familiar
Hive uses a leader key like tmux's prefix: Ctrl+Space by default, then v or % to split right, - or " to split below, z to zoom, d to detach. Every key can be rebound in config.toml, and Ctrl+Space : opens a palette of every command.
Using both
They don't conflict. Hive is a terminal program, so it runs inside a tmux pane (we test it that way), and its default leader doesn't collide with tmux's Ctrl+b. A common setup on a remote machine: tmux for the SSH session, Hive inside it for the agents.
Which should you use?
- tmux if you run one agent at a time, already have a tmux setup you love, or work on machines where you can't install anything.
- Hive if you run several agents, across more than one repository, and want to know at a glance which one needs you.
Hive is free, MIT-licensed and installs with one command. Try it, or read the longer comparison with tmux, Zellij and herdr.
