Show HN: Cetus – A macOS App for Claude Code, Codex, OpenCode, and More

Hi HN - I built Cetus after using different agent runtimes together in my terminal (which was totally a chaos!).

I use Claude Code, Codex and OpenCode together, but I wanted a desktop workflow that wasn’t tied to one of them. I kept coming back to my terminal and keep forgetting which agent had finished what. Especially, I want to manage different cron jobs together (Claude Code is better at frontend so I want it to write SEO pages, while Codex is better at logic so I want it to review PRs).

So I built Cetus, with support for different runtimes, and many other stuff(quick launcher allowing you to use it using a global shortcut, cron jobs for different runtime, and kanban view). Under the hood it's a Tauri app with a Rust host.

I’d especially like to know: Do you also switch between multiple agent runtimes, or have you mostly settled on one? Does Cetus make sense to you?
