OpenSquirrel

OpenSquirrel is a GPU-rendered control plane for running Claude Code, Codex, Cursor, and OpenCode side by side — built in Rust with GPUI (same engine as Zed editor). If you're juggling multiple agents, this gives you a native tiled layout instead of four terminal tabs.

The coordinator/worker delegation is the standout feature: a primary Opus agent can spawn focused sub-agents, with workers returning condensed results. Sessions persist through restarts. Remote machine targeting via SSH + tmux means your local Mac can orchestrate cloud GPUs. No Electron, no web views — pure Metal rendering.

Use this when you're a multi-agent power user who wants visual control without Electron overhead. Skip this on Linux or Windows — macOS-only (Metal GPU required).

The catch: very early stage from a solo developer (Elliot Arledge). The GPUI dependency ties it to Zed's rendering stack, and macOS-only limits the audience significantly. Cool demo, uncertain maintenance trajectory.
