Why Orbit

• Direct and private. Data moves only between your two devices, over mutual TLS with certificates pinned at pairing. There is no Orbit server, no account and no analytics.
• Connects over whatever is available. A USB cable, USB tethering, your phone's hotspot or a shared Wi-Fi network. Orbit tries every route at once and keeps the first one that answers, with no firewall rules or setup.
• Free and open source. Licensed under AGPL-3.0, with no ads, subscriptions or in-app purchases.

Features

Universal clipboard	Copy on your PC and paste on your phone, automatically. Send text from your phone with one tap: a button, a Quick Settings tile, a notification action, or by sharing text to Orbit. Copies marked private by password managers are never synced
Notifications	Phone notifications appear as native Windows notifications with app icons. Dismiss one on your PC and it clears on your phone. Choose which apps forward, hide message text, pause, or silence alerts while your PC is locked
File transfer	Drag and drop files onto Orbit, or choose Share → Orbit on your phone. Transfers show progress and resume automatically if the connection drops
Screen mirroring	View and control your phone from your PC with mouse, keyboard and audio, in a window or full screen. Show the phone's camera instead of its screen. Capture screenshots and recordings. Works over USB, or over Wi-Fi after a one-time setup
Media controls	See what's playing on either device, then play, pause, skip or seek from the other. Phone audio appears in the Windows media controls, and PC playback in the phone's media player
Links	Share a link to Open on your PC and it opens in the PC's browser. Copy a link on the PC and send it to the phone from the tray or with Ctrl+Alt+L
Phone remote	Use the phone as a touchpad, keyboard or slides clicker for the PC, change or mute its volume, lock it, put it to sleep or shut it down, and run your own commands. The PC decides which buttons the phone gets, and every action shows a notification there
Phone battery	Charge level, charging state and time to full in the app, the system tray and the tray flyout, with a low-battery alert
USB modes	Choose what the cable does: charging only, USB tethering (your laptop goes online through your phone) or file sharing (your phone opens in File Explorer). Switch at any time from either device
Earbuds	Battery and Play Here for any Bluetooth earbuds. Noise control (Off / Transparency / ANC), sound settings and tap actions for supported realme, OnePlus and OPPO models, on both devices
Pairing	Scan a QR code, or plug in your phone and select Pair over USB

Requirements by feature

Feature	Requires
Clipboard, notifications, files, battery, media controls, links, phone remote	Nothing extra: USB tethering, a hotspot or a shared Wi-Fi network
Pair over USB, USB modes, mirroring over USB	USB debugging on the phone (how to enable it)
Mirroring over Wi-Fi	Wireless debugging (a one-time QR setup in Orbit) and both devices on the same Wi-Fi network
Showing the phone's camera	Android 12 or later, and mirroring working (USB debugging, or wireless mirroring set up)

Install

System requirements: Windows 10 (1809) or Windows 11, x64 · Android 10 or later.

1. Install on Windows. Download OrbitSetup-<version>.exe from Releases and run it. Orbit runs in the system tray.

2. Install on Android. The simplest way: turn on USB debugging, connect your phone and select Install on phone on the PC's pairing screen. Orbit installs the Android app and pairs both devices in one step.

   Alternatively, download Orbit-<version>-android.apk from the same release and install it, allowing installs from your browser or file manager when prompted. Some phones block this with "App blocked to protect your device"; in that case, install over USB (why).

3. Grant permissions. Open Orbit on your phone and allow the permissions it requests. Notification access and "stay connected" are the most important.

4. Pair (if you didn't install over USB). Connect with USB debugging on and select Pair over USB on your PC, or tap Scan QR code on your phone and point it at your PC.

To verify your download, compare its SHA-256 against SHA256SUMS.txt in the release.

Privacy and security

Orbit has no servers, no account and no analytics. Your data travels only between your own two devices, encrypted with TLS using keys pinned when you pair. Read the privacy policy for details, and report vulnerabilities as described in SECURITY.md.

Build from source

Requires Windows with the .NET 8 SDK and JDK 17–21:

.\tools\fetch-thirdparty.ps1   # scrcpy server, FFmpeg and adb binaries (checksum-verified)
.\build.ps1                    # both apps into .\dist
dotnet test windows\Orbit.Tests
cd android; .\gradlew.bat testDebugUnitTest

docs/ARCHITECTURE.md explains how Orbit works, and docs/PROTOCOL.md documents the wire protocol. Contributions are welcome; please read CONTRIBUTING.md first.

Known limitations

• Clipboard sync supports text only.
• Android only lets the app in the foreground read the clipboard, so sending from phone to PC takes a tap. PC to phone is automatic.
• Orbit connects one phone to one PC at a time.
• The phone's touchpad and keyboard can't control administrator windows or the Windows lock screen.
• Orbit can't turn on your phone's hotspot (Android doesn't allow apps to), but it connects as soon as your laptop joins it.
• The QR scanner uses Google Play services, so this build isn't on F-Droid yet. Pair over USB works without it.
