wezmux

A fork of WezTerm that adds workspace management for multi-agent terminal workflows. Wezmux focuses on running multiple coding agents side-by-side and making each workspace's state visible at a glance.

Why ?

Because cmux was disappointing (and I don't need a browser in my terminal) and I mean WezTerm is just the dream

What's different from WezTerm

Persistent sidebar showing per-workspace metadata:

• Git branch and dirty status
• PR number and status (via gh CLI)
• Listening ports
• Agent status line (via OSC 7777)
• Unread notification badges

Notification tracking (on top of WezTerm's existing OSC 9 toasts):

• Blue ring on panes with unread notifications
• Unread badge counts in the sidebar
• Option+U to jump to the last unread notification

• Claude Code — hooks injected automatically via wrapper script (no setup needed)
• Codex — run make install-codex-hooks to set up hooks in ~/.codex/hooks.json
• Status, tool activity, and output previews shown in the sidebar for both

OSC 7777 agent status protocol for structured status reporting:

Session save/restore on quit and relaunch:

• Workspace layout and split pane structure preserved
• Per-pane CWDs restored
• Scrollback history with ANSI colors
• Sidebar metadata cache (no blank-state flash on relaunch)
