tmux Alternatives
tmux alternatives come up when the prefix-key workflow gets old, when you want layouts and session restore without plugins, or when what you actually need is to run several coding agents at once, each isolated in its own worktree.
Last updated
What to look for in a tmux alternative
- Friendlier defaults and built-in layouts
- Sessions that survive restarts
- Agent-aware features: alerts, worktrees, and review
- A way to keep your existing tmux sessions
Recommended options
Agentastic
Our pickNative macOS workspace with 55 built-in agent definitions and a git worktree or container per task. Built-in editor, browser, diff viewer, and AI code review.
Zellij
MIT-licensed terminal workspace with layouts, floating panes, WebAssembly plugins, and session resurrection built in. Runs on Linux, macOS, and Windows.
cmux
Free, GPL-licensed Ghostty-based Mac terminal for coding agents, with vertical tabs, notification rings, a scriptable browser, and a diff viewer. You script the worktrees.
Warp
Open-source (AGPL-3.0) terminal turned agentic development environment, with local and cloud agents and an agent CLI, for macOS, Windows, and Linux.
How to switch from tmux cleanly
Zellij is the closest swap and adds layouts, floating panes, and session resurrection. cmux is a Mac terminal for agents that can mirror remote tmux sessions in a beta feature. Agentastic keeps tmux working: run tmux -CC inside it and each session opens as native tabs, locally or over SSH.
Common questions
Zellij vs tmux: what is the difference?
Both are terminal multiplexers. Zellij ships layouts, floating and stacked panes, WebAssembly plugins, and session resurrection out of the box. tmux is the long-established standard and runs on Linux, macOS, and the BSDs.
cmux vs tmux: which do I need?
tmux runs inside any terminal and keeps sessions alive on a server. cmux is a Mac terminal app with tabs, notification rings, and a browser for agents. Many people use both: tmux on the server and a GUI on the Mac.
Can I use Claude Code with tmux?
Yes. Claude Code runs inside tmux like any terminal program. In Agentastic, tmux -CC sessions open as native tabs, so you keep tmux's persistence with a GUI on top.
