Reach any service over your SIMSY connection
The SIMSY Proxy app turns your API key into a dial-tone for everything on your SIMSY network. Pick a device, pick a port, and the app makes the service available locally on your phone or laptop. No public exposure, no port forwarding, no firewall holes.
One paste, one tap, one local port
1. Paste your API key. The Proxy app authenticates against the SIMSY platform using your API key. The key is stored locally on the device running the app.
2. Pick the device and port. The app lists every SIM and connected device on your account. Select one, choose a port (8080, 22, 11434 — whatever the service is on), and the app opens a tunnel.
3. Connect locally. The tunnel surfaces the remote service on a localhost port. Your tools talk to localhost:8080. The traffic actually rides the SIMSY core to the SIM.

# Behind the scenes:
