MultiPane – Multi-agent coding session chat deck

Bring Claude, Codex and OpenCode into one window so they can review each other

Problem

Many developers already pair with a single coding agent, but trying to have one agent implement while another reviews means switching terminals and copy-pasting context manually. Someone even built a local tool to let Claude, Codex and OpenCode talk to each other, proving that multi-agent pair programming is a real workflow being explored.

Solution

A local desktop app that shows multiple CLI coding agents side by side as chat panes. You can assign one agent as driver and another as reviewer, and diffs plus review notes are relayed automatically between them. All conversations and code stay on your machine.

Users

Heavy developers already using Claude Code, Codex or OpenCode, tech leads, and pair-programming enthusiasts

MVP

Configure and launch multiple locally installed CLI agents; show each agent's session side by side; send the latest diff to another agent for review manually or automatically; keep all messages local; support macOS and Windows

Revenue

Free base app plus one-time Pro license for more agents, auto-review rules and team-shared configs; or a per-seat monthly subscription

Why now

CLI coding agents are exploding, yet multi-agent collaboration is still stuck in scripts and hacks with no friendly local UI; a solo dev can ship a lightweight wrapper fast
