Turn your phone — or any device with a web browser — into a mouse, keyboard, and remote control for a Windows PC over your local Wi-Fi.
Free. No ads, no accounts, no cloud. Everything stays on your network: the phone talks straight to a tiny server on your PC, PIN-protected, and nothing ever leaves your LAN. It's built to be firewall-friendly: the open port is scoped to your own subnet, so it works even on a "Public" Wi-Fi profile — a common reason phone-remote apps fail to connect on Windows 11.
Two ways to connect:
- Android app — the full-featured client (trackpad gestures, custom macros, file transfer, Wake-on-LAN, auto-discovery).
- Browser remote — open
http://<pc-ip>:8770/on any device on the Wi-Fi. Nothing to install. Scan the QR code in the server window to connect in one tap.
| Feature | App | Browser |
|---|---|---|
| Trackpad (move, tap, right/middle-click, scroll, drag-select) | ✅ | ✅ |
| Full keyboard — typing, shortcuts (Ctrl+C/V…), F-keys, modifiers | ✅ | ✅ |
| Media & volume keys | ✅ | ✅ |
| Presentation controls (start, next/prev, black, end) | ✅ | ✅ |
| App launcher (your own quick-launch tiles) | ✅ | ✅ |
| Clipboard sync (push/pull text between phone and PC) | ✅ | ✅ |
| Quick View — pull a screenshot of the PC, pinch-to-zoom, pick a monitor | ✅ | ✅ |
| Power (lock, sleep, restart, shut down, log off) | ✅ | ✅ |
| Custom macros — buttons that fire keystrokes or launch apps | ✅ | — |
| Gamepad — virtual Xbox 360 controller; on-screen pad or forward a real one | ✅ | — |
| File transfer (phone ↔ PC) | ✅ | — |
| Wake-on-LAN — turn the PC on from your phone | ✅ | — |
| Auto-discovery (finds your PC on the Wi-Fi) | ✅ | — |
| Browser client — zero install, QR scan-to-connect | — | ✅ |
Nothing is stored in the cloud; Quick View screenshots are never written to disk — they're streamed once and dropped when you close the viewer.
The Gamepad feature emulates an Xbox 360 controller through the ViGEmBus driver (an optional, opt-in component the PC installer offers) — drive it with the on-screen pad, or pair a real controller to your phone and forward it. Releasing or disconnecting always returns the pad to neutral, so nothing stays "held."
Grab the latest JawnRemote-Server-Setup.exe (PC) and JawnRemote.apk
(Android) from the Releases
page — or from jawnston.com/jawnremote.
PC server (Windows): run the installer. One UAC prompt, then Next → Install →
Finish. It drops a single self-contained JawnRemoteServer.exe (Python bundled in
— no install needed) and opens the firewall for TCP+UDP 8770, scoped to
localsubnet so the port is invisible to the internet. A small window shows your
PC's address, the PIN, and live status.
Phone: install the APK (enable "install unknown apps" when prompted), make sure it's on the same Wi-Fi, tap your PC under Discovered, and enter the PIN.
Browser: open http://<pc-ip>:8770/ on any device on the network, or scan the QR
code shown in the server window. Enter the PIN and you're in.
- Local-only. The phone/browser connects directly to your PC over the LAN. There is no cloud service, no account, no telemetry. JawnRemote never phones home.
- PIN handshake on every connection, with a brute-force lockout after repeated bad PINs.
- Firewall scoped to
localsubnet— the port is reachable from your own network only, not the internet. - Open source. The whole thing is in this repo — read it, audit it, build it
yourself. The PC server is ~zero-dependency Python standard library; you can run it
straight from source with
py server/server.pyif you'd rather not run the.exe. - SmartScreen note: the installer isn't code-signed yet, so Windows may show "Windows protected your PC / unknown publisher." Click More info → Run anyway, or build it yourself from source (below).
| Part | Folder | Tech |
|---|---|---|
| PC server | server/ |
Python 3 (standard library only) — injects input via the Win32 SendInput API; captures the screen via GDI; serves the browser client over a hand-rolled HTTP/WebSocket on the same port |
| Phone app | app/ |
Flutter (Dart) — gesture trackpad, keyboard, and the rest |
The app speaks a tiny newline-delimited JSON protocol over TCP (PIN handshake + UDP broadcast for auto-discovery). The browser speaks the same JSON schema over a WebSocket multiplexed onto the same port, so both clients share one server with one firewall rule.
pip install pyinstaller
cd server
py -m PyInstaller --noconfirm JawnRemoteServer.spec
cd ..
"C:\Program Files (x86)\Inno Setup 6\ISCC.exe" installer\JawnRemote.iss
Output: installer\Output\JawnRemote-Server-Setup.exe. For development, run the
console server directly — no build needed:
cd server
py server.py # --pin 1234 to set a PIN, --no-auth to disable auth, --port to change port
cd app
flutter run # on a connected device/emulator
flutter build apk --release # build/app/outputs/flutter-apk/app-release.apk
Release builds are signed with a local keystore referenced by
app/android/key.properties (git-ignored; create your own with keytool, e.g.
storeFile=%USERPROFILE%/jawnremote-release.jks). Debug builds need no signing.
Client → server (selected):
Server → client:
{"t":"welcome","ok":true,"server":"JawnPC"} // or ok:false, err:"bad_pin"
{"t":"clip","s":"..."} // clipboard contents
{"t":"displays","list":[{"index":0,"w":1920,"h":1080,"primary":true}, ...]}
{"t":"shot","w":1600,"h":900,"img":"<base64 png>"}UDP discovery: client broadcasts {"t":"discover","app":"JawnRemote"} to port 8770;
the server replies with its name and address.
- Can't connect / times out: the firewall isn't open, or your Wi-Fi is
Public. The installer opens the firewall for all profiles; if you're running from source, add the rule manually (TCP+UDP 8770) or runserver/setup_firewall_ADMIN.bat. Make sure phone and PC are on the same network (not a guest/IoT SSID). - "Wrong PIN": check the PIN in the server window (
server/pin.txt). - Discovery finds nothing, but manual IP works: the UDP rule is missing or the router blocks broadcast. Tap Add PC and type the IP shown in the server window.
- Cursor too fast/slow: Settings → Pointer speed. (Turning off Windows "Enhance pointer precision" makes movement perfectly linear.)
