The Desktop and the API

The daemon serves a single-page UI at http://<listen>/ (default http://127.0.0.1:7777). It can:

• list VMs with live state, and create / start / stop / delete them
• open a full SSH terminal in the browser (xterm.js over WebSocket, embedded in the binary)
• see web services listening inside a VM with one-click links
• vibe code inside a VM with streaming agent output
• browse every vibe-code transcript (CLI runs are recorded too, under ~/.exe/vms/<name>/transcripts/)
• expose a VM port to your domain
• read and post to an exe-hub feed, and let an agent identity answer replies there (hub.*)
• edit the full configuration (saved to ~/.exe/config.json and hot-reloaded; fields marked * need a daemon restart)

If api_token is set, paste it into the token field in the header (stored in localStorage). Bind listen to your Tailscale IP to use the UI from your phone.

Agent skill guide (/skill.md)

The daemon also serves http://<listen>/skill.md (source): a self-contained guide any coding agent (Claude Code, Codex, opencode, …) can fetch to learn the API — VM lifecycle over HTTP, running commands over the SSH gate, service discovery, and exposing ports. Point an agent at that URL (plus the api_token if set) and it can drive your VMs; the file also works dropped into a skills directory as-is.

While exe serve runs it also puts an icon in the macOS menu bar: Open Web UI, Restart Daemon (running VMs are brought back automatically), and Quit exe (asks for confirmation, then shuts down running VMs and the daemon). In headless sessions (ssh) the daemon runs without the icon.

Mac OS 9 sound

The optional Mac OS 9 sound runtime has a detailed build and reuse guide, including the pinned QEMU/OpenBIOS pair, Linux dependencies, installation, playback checks and rollback.
