I built a HUD for running many Claude Code sessions on a Mac

#showdev #claude #opensource #ai

I run several Claude Code sessions at once, often with subagents, and I kept losing track of which one was working, which one was waiting for me and which one wanted approval. So I built a native Mac app around them: Atalay's Terminal.

Claude Code sessions orbiting live, with their subagents, tool calls, files, web research and spend

What it does

  • Every Claude Code session sits on a live orbit map, coloured by state: working, waiting for you, asking for approval.
  • Subagents, tool calls, the files they touch, web research, tokens and spend update as they happen.
  • Each chat has its own window, but the session lives in the background: close the window or quit the app and Claude keeps working. The window comes back with its history.
  • Dev servers and test watchers fly around the orbit as cars and park when they're idle.
  • Friends, messages, and XP for the time you actively work, from Academy Student up to Kage, with a weekly leaderboard.

A chat in its own window

How it's built

  • Swift (SwiftPM) and AppKit, with SwiftTerm for the terminals.
  • Every chat and terminal runs in a detached /usr/bin/screen session, which is why they survive the app quitting.
  • The dashboard is a web page in a WKWebView; the orbit map is three.js.
  • It reads Claude Code's own files in ~/.claude, read only. None of it leaves your Mac; the README lists exactly what the small server behind friends and levels receives.

Try it

Free and open source (MIT), macOS 13+, Apple Silicon and Intel.

I'd love your feedback, especially if you run a lot of sessions in parallel. If you try it, add me as a friend: click the logo at the top left, then FRIENDS, then owen watts#8049.
