TabDesk vs scrcpy: which one should you use?

What is scrcpy?

scrcpy is an open-source command-line utility from Genymobile that mirrors an Android device on a desktop. You connect your phone over USB (or Wi-Fi), run scrcpy in a terminal, and a window opens showing the device's screen, with low latency, mouse and keyboard input forwarded to the phone.

Under the hood, scrcpy pushes a small Java server (scrcpy-server.jar) to the device, sets up an ADB reverse tunnel, and streams an H.264-encoded video feed back to the desktop client. The encoding happens directly on the device's hardware encoder, which is why it is so fast, typically under 70 ms of glass-to-glass latency.

scrcpy is excellent. It is fast, free, well-maintained and does one thing very well. But it is also a CLI tool: every option is a flag, every session is a new terminal command, and there is no concept of "multiple apps in parallel" out of the box.

What TabDesk adds on top of scrcpy

TabDesk uses the unmodified scrcpy-server.jar from Genymobile. Only the desktop client is replaced. What TabDesk adds:

• A tabbed interface. Every session is a tab. Switch between mirrored apps the same way you switch browser tabs.
• Multi-instance on a single device. TabDesk uses Android's virtual display API (--new-display) to launch each selected app on its own display, so several apps truly run side by side instead of stacking on top of each other.
• Multi-user Android detection. TabDesk scans every Android user account on your device and lists each app once per account. That includes Work Profile, Xiaomi Second Space, Samsung Secure Folder, Shelter and Island.
• Zero-install bundling. adb and scrcpy-server are bundled inside the app. No brew install, no scoop install, no PATH editing.
• Performance presets. Ultra (4K · 60 fps), High (1080p · 60 fps), Medium (720p · 45 fps), Low (540p · 30 fps), and a Custom preset to tune bit rate and i-frame interval per session.

When to stick with scrcpy CLI

• You only ever mirror one app or one screen at a time.
• You are comfortable with the command line and prefer scripts over GUIs.
• You need a flag that TabDesk does not yet expose (--lock-video-orientation, --turn-screen-off, etc.).
• You want a strictly free, open-source (Apache 2.0) tool.
• You are on Linux, TabDesk does not yet ship a Linux build, scrcpy does.

When to switch to TabDesk

• You want to run two or more Android apps in parallel on the same phone (think: dual WhatsApp, gaming + Discord, mirroring + remote control).
• You use a Work Profile, Samsung Secure Folder, Xiaomi Second Space, Shelter or Island and want to launch apps from those user spaces too.
• You do not want to install adb and scrcpy separately just to mirror your phone.
• You prefer clicking a tab over typing a new command.
• You want the same engine as scrcpy but with a polished GUI.

Latency and performance

• Identical to scrcpy CLI. Same scrcpy-server, same H.264 settings, same TCP-via-ADB-reverse transport.
• Hardware-accelerated decoding. WebCodecs uses VideoToolbox on macOS and Media Foundation on Windows.
• Sub-100 ms latency at 60 fps on a modern Mac or PC.
• Multi-instance scales linearly. Each active tab opens its own scrcpy-server pipe, bandwidth and device CPU add up. Inactive tabs drop frames to keep the foreground smooth.

Installation

scrcpy CLI

• macOS: brew install scrcpy (also pulls in Android platform-tools).
• Windows: scoop install scrcpy, or download the ZIP and add it to PATH.
• Java required for some advanced features.

TabDesk

• Download the .dmg (macOS) or .exe (Windows) from GitHub Releases and open it.
• adb and scrcpy-server are bundled inside the app.
• No PATH editing, no external dependency.
