A tiny digital signage stack for places where you can't install software as admin. Three pieces:
- catstage — fullscreen viewer (Tauri / WebView2). Drop the EXE on a machine, point it at a broker, walk away.
- catsocks — dumb WebSocket relay. Runs on Cloudflare Workers' free tier. Sees only opaque ciphertext.
- catc — the CLI. Drives one or many stages from your laptop.
End-to-end encrypted. No accounts, no master server, no telemetry. Stage state survives reboots and broker outages.
Early. v1 targets Windows x64 only — macOS / Linux / ARM distribution may follow. Auto-update is not in v1 (corp proxies block executable downloads in our test environment); updating a stage is a manual EXE swap. WSL/Linux is the recommended dev path.
# 1. Deploy the broker (once per deployment)
cd crates/catsocks && wrangler deploy
# -> wss://catsocks.<your-acct>.workers.dev/r/<your-room>
# 2. On each stage machine
catstage.exe --install-autostart --socks wss://.../r/<room> --name kitchen --screen 2
# Optional: --screen is 1-based. If unavailable, catstage falls back to primary monitor.
# 3. On your laptop
catc init --socks wss://.../r/<room>
catc stage add kitchen # the name shows on the stage's catcast://about page
catc config import config.yaml --name kitchen
catc nav https://example.com --for 5mSee examples/ for config.yaml, aliases.yaml, and a default Rhai logic.
