The terminal
your agents live in.

Seedmux is a native macOS terminal built for the agent era. Sessions survive quits and crashes, every pane knows when Claude or Codex needs you, and one prompt can put a whole team to work.

v0.1.2 · macOS 13+ · native AppKit, zero Electron

Processes outlive the app. ⌘Q with agents mid-task. Agent-aware panes. Claude, Codex, Grok, OpenCode. Native AppKit + GPU. Ghostty renderer. No web views.
// sessions

⌘Q is no longer a threat.

Every pane runs inside a detached tmux session owned by the system — not by the app. Quit, crash, update Seedmux mid-build: your shells and agents keep working in the background.

Relaunch, and every workspace, tab, split and scrollback comes back exactly where it was. The agent that was thinking is still thinking.

Stop babysitting terminals.

Seedmux detects Claude Code, Codex, Grok and OpenCode running inside any pane and surfaces their real state — working, waiting for your approval, finished — right on the tab.

Glance at the sidebar instead of cycling through windows. Come back exactly when you're needed, and never miss a permission prompt buried three splits deep.

// agent team

One prompt. Many hands.

Ask the agent you're talking to for help, and Seedmux becomes the control plane: it opens worker panes, dispatches 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.
