tmux alternative for Claude Code and Codex: Agentty vs tmux
By LEE YONGBEOM · Creator of Agentty · Checked
TL;DR
- Pick tmux if you live on remote servers over SSH, want sessions that survive closing the terminal, and are happy to script the rest yourself.
- Pick Agentty if you run several Claude Code or Codex sessions on your own machine and want to see which one is waiting for you, with a git worktree per session.
- They are different kinds of tool: tmux is a terminal multiplexer that knows nothing about what runs in its panes; Agentty is a terminal app built around AI coding agents.

Where tmux is the better pick
- Servers and SSH. tmux runs on the remote machine itself, so a session keeps going when your connection drops and you reattach from anywhere. Agentty runs on your own computer.
- Everywhere already. tmux is in nearly every package manager, works inside any terminal you already use, and has decades of configuration and plugins written for it.
- Scripting. Every tmux action is a command, so layouts and workflows can be scripted completely.
Where Agentty goes further
- It knows what the agent is doing. Each pane shows whether its agent is working, done, waiting for you or asking for permission, and the pane that needs you is highlighted.
- A git worktree per session. A new AI session in a busy project gets its own worktree and branch, so two agents do not edit the same files.
- Sessions you can find again. Search Claude Code and Codex sessions by title, message or folder, resume them, and move one between the two agents.
- Context between agents. Link two sessions so context flows live between Claude Code and Codex, one way or both.
- Windows without WSL. Agentty runs natively on Windows and Linux as well as macOS.
How this was checked
Every line about tmux was read off its own README, repository or site on . A “not documented” means the project does not describe the feature, not that it cannot do it. This is a comparison of what each project documents, not a benchmark. If something here is out of date, tell us and it will be corrected.
Frequently asked
- Can I keep using tmux inside Agentty?
- Agentty is a real terminal, so tmux runs in its panes like any other program. Agentty's own splits, tabs and workspaces cover what most people use tmux for on their own machine.
- Is Agentty a tmux replacement on a server?
- No. Agentty is a desktop app that runs on your own computer. For long-running sessions on a remote machine over SSH, tmux is the right tool.
- Is Agentty free like tmux?
- Yes. Agentty is free, with no account or paid tier, and its source is public under the Apache License 2.0.
