Setup Guide

Get streaming in about 5 minutes.

Griffin Stream has two free pieces: the app on your phone or tablet, and a Windows server that runs on the PC you want to control. You pair them once, then it’s a single tap to reconnect from then on.

What you’ll need

An Android phone or tablet.
A Windows 10 or 11 (64-bit) PC.
Both on the same Wi‑Fi / local network for pairing and everyday use.

1. Install the app

Install free Griffin Stream from Google Play. You can install the Windows server on your PC first — the app and server are both free.

2. Download & run the Windows server

On your PC, download the server from the PC server page and run GriffinStreamServer-Setup.exe. Launch Griffin Stream Server after it installs — it opens a small window showing a pairing PIN and your PC’s local IP address.

3. First launch on Windows (SmartScreen)

Because the app is new and not yet code-signed, Windows may show a blue “Windows protected your PC” screen. This is expected while the app builds reputation — click More info, then Run anyway. The server is open and safe to run on your own PC.

4. Pair once

Open the app and enter your PC’s IP address (shown in the server window). The port is 8888 by default.
Tap Connect. The first time, the app will ask for the pairing PIN.
Type the PIN shown in the server window and confirm. Your device is now paired and the stream starts.

You only pair once. Your device is remembered securely, so future connections are a single tap — no PIN needed.

5. Reconnect & Wake-on-LAN

Next time, just tap your saved PC to reconnect. If your PC is asleep, add its MAC address in the app and use Wake PC to power it on over the network before connecting.

6. Network tip

Keep the phone and PC on the same local network. Use the local IP shown in the server window. Do not expose TCP port 8888 to the public internet. Traffic always goes directly to your own PC — there is no Griffin Stream cloud relay.

7. Free vs Pro

The Android app is completely free. Pro is a one-time license for the Windows PC server — not an in-app purchase. When your phone connects to a Pro server, higher-quality streaming options unlock automatically in Settings.

Free server: full mouse, keyboard & gamepad control; up to 1080p at 60fps (H.264); Auto, Performance & Balanced quality presets; Wake-on-LAN; and multiple paired PCs.
Pro server: 90/120fps, 1440p & native resolution, HEVC 10-bit for less banding, maximum bitrate, the Quality & Max presets, the full Advanced panel, premium cursor colors, and click feedback (show click rings).

Buy Pro on griffinstream.app/pro (checkout via Dodo Payments). Your license key is emailed after purchase. Paste it into the server dashboard under Activate, then reconnect the phone.

Seats & reinstalls: each key works on up to 3 PCs. Use Deactivate this PC on the server dashboard to free a seat. If a PC is gone, manage seats in your Dodo customer portal. When uninstalling the Windows server, choose to keep license data if you will reinstall on the same PC.

8. Manage or unpair devices

In the app, remove a saved PC from the connection list to forget it. On the PC, use the server dashboard (or debug log commands) to review or remove paired devices at any time.

Troubleshooting

Can’t connect: confirm the server is running, both devices are on the same network, and Windows Firewall allows Griffin Stream (the installer adds a rule).
Reconnect after a server update: just tap your saved PC — the app remembers it. No PIN needed unless you wiped pairing data on the PC during reinstall.
Wrong PIN: a fresh PIN is generated each time the server starts — use the one currently shown in the server window.
