OpenSquirrel
For people who get distracted by agents. A native Rust/GPUI control plane for running Claude Code, Codex, Cursor, and OpenCode side by side — because if you're going to be squirrely, you might as well optimize for it.

OpenSquirrel is a native desktop app that puts Codex, Cursor, and OpenCode in one window so you stop losing track of what each one is doing. A control plane for your AI coding agents, built in Rust with the GPUI framework.
What's free: Everything. MIT licensed, fully open source. No paid tier, no cloud service.
The pitch is honest: you're squirrely, you jump between agents, and you need a way to see them all at once without alt-tabbing through six terminal windows. The Rust/GPUI foundation means it's fast and native, not an Electron wrapper eating 2GB of RAM.
The catch: this is early, so it's not battle-tested yet. GPUI (Zed's UI framework) is relatively new itself, so you're building on new foundations. If you only use one AI coding tool, this adds zero value. It's specifically for the multi-agent workflow that a growing number of developers are adopting.
Free vs Self-Hosted vs Paid
fully freeWhat's Free
Everything. MIT license, no restrictions. The entire application is open source with no paid tier or hosted service.
Build Cost
You need Rust installed to compile from source. If you already have a Rust toolchain, it's a cargo build. If not, budget 15-20 minutes for setup.
The Real Cost
The AI coding tools you're running inside it. Claude Code Pro ($20/mo), Cursor Pro ($20/mo), Codex -- those subscriptions add up. OpenSquirrel is free but it's a window into expensive tools.
Value Proposition
If you're already paying for multiple AI coding tools and losing context switching between them, this costs $0 and saves real time. If you use just one tool, skip it.
Completely free -- the expensive part is the AI coding tools you're already paying for.
