Know what every agent is doing.
Seedmux recognizes Claude Code, Codex, Grok, OpenCode, Kimi, Pi and Antigravity in any pane and puts their real state right on the tab.
Agents in your other spaces stay listed in the Agents panel, so nothing finishes unnoticed.
When an agent needs you, the notch lights up.
Permission prompts and questions surface in the notch the moment they happen — with the agent, the project and the exact command.
Allow a Bash command right there, or jump straight to the pane. No more prompts buried three splits deep.
⌘Q is no longer a threat.
Every pane lives in a tmux session owned by the system, not by the app. Quit, crash or update Seedmux mid-task and your agents keep working.
Reopen it and every space, tab, split and scrollback is exactly where it was — plus whatever they finished while you were away.
A space for every project.
Group tabs into spaces, give each its own colour, and swipe between them.
The Agents panel comes with you: a job finishing in Research still shows up while you're heads-down in Work.
One prompt. Many hands.
Ask the agent you're talking to for help and Seedmux becomes the control plane: it opens worker panes, hands subtasks to codex, grok, opencode or another claude, and collects a receipt from each when the work lands.
Your terminal stops being a stack of tabs and starts being a team you can watch.
It's also just a very good terminal.
