Multi-agent terminal collaboration pane

Let coding agents in separate terminal panes message, coordinate, and span machines

Problem

Many devs now run several coding agents (Claude Code, Codex, Gemini) in separate terminal panes, but the panes are unaware of each other and coordination is manual copy-paste. Users report it is painful to make multiple agent panes cooperate, and cross-device control is even worse. Existing tools only show agent quotas in the menu bar and do not solve pane-to-pane communication or scheduling.

Solution

A terminal multiplexer (tmux-compatible shortcuts and config) where every pane has an inbox. You can send messages or commands to another pane, with three modes: manual, shell-execute, or hand off to an internal agent. Machines on the same LAN or Tailscale can pair once, and a phone can scan to observe and control. The goal is to make multi-agent collaboration a native terminal primitive.

Users

Developers running multiple coding agents, engineers working across machines, power tmux users

MVP

A tmux-compatible layer with an inbox per pane; three pane modes (manual, shell exec, internal agent); basic cross-machine pairing over Tailscale/LAN; a mobile read-only observer view via QR scan; preserves existing tmux shortcuts and config

Revenue

Open-source core with a subscription for cross-machine pairing and mobile access; a team tier with shared panes and centralized logs; optional one-time purchase for a personal pro license

Why now

Coding agents are exploding in number while multi-agent coordination is still manual. The terminal toolchain is mature and unclaimed by giants, so a solo dev can build on the tmux ecosystem quickly.
