A terminal multiplexer that keeps many shells in one window, survives disconnect so you can reattach later, and splits panes. It is the session-management foundation that agent multiplexers like herdr build on, though tmux itself does not know what an agent is.
Strengths
- Persistent sessions survive disconnect; reattach later
- Split one window into many panes and shells
- Runs anywhere, including over SSH, as a single binary
- Battle-tested and ubiquitous
Tradeoffs
- Not agent-aware; no notion of what an agent is doing
- Keyboard-driven with a real learning curve
- No built-in state or status for agents
