scrcpy is Apache-2.0 open source from Genymobile/scrcpy. Prefer GitHub Releases, enable USB debugging knowingly, and skip random mirror sites.
What the project states
The README focuses on lightness, low latency, no account, no ads, and nothing left installed on the device after a session. USB mirroring does not require root.
Download safety
The README warns that the GitHub repo is the only official source. Random sites that reuse the project name are not trusted download doors for screen mirroring installs.
What you still decide
USB debugging is powerful. Authorize only computers you trust. Lab phones should clear authorize lists when hardware changes hands. Security contacts live on the GitHub security tab.
Licence: Apache-2.0. Pillar: screen mirroring. Safe download: download safe.
Desk notes
Write the Releases URL and the exact archive name on the machine ticket. Shared labs that skip that note rediscover Softonic bookmarks under pressure and lose an afternoon to the wrong screen mirroring binary.
Travel kits
Travel kits should copy a fully extracted folder only after one local proof. A lone scrcpy.exe without companions fails in confusing ways that look like cable problems.
Family and classroom desks
Family PCs benefit from one extract path and a ban on mystery shortcuts in Downloads. Contractors should receive a machine they control plus a phone they can authorize for USB debugging.
Classroom images should re-prove one mirrored frame after every reimage. That habit catches vanished portable folders before a demo starts.
Filename checks
When a colleague pastes a random best-download link, compare the filename to scrcpy-win64 zip or the matching tarball. Mismatch means stop and reopen GitHub Releases.
Optional power features
Audio forwarding, camera mirroring, and OTG mode remain optional until basic screen mirroring works. Recording flags can wait until the first click reaches the phone.
Phrase and filenames
Cast Quill keeps the write phrase on screen mirroring so searchers who typed the job land on a named zip. Product filenames still appear in commands and release tables where accuracy matters.
Upstream docs
Upstream docs on Genymobile/scrcpy remain the source for new flags. This guide maps install doors and first-hour habits, not every experimental option in the help text.
Update doors
Prefer returning to the same update door you documented: zip, winget Genymobile.scrcpy, brew formula scrcpy, or the linux tarball. Mixing doors without notes creates duplicate PATH entries.
OS prompts
If SmartScreen or Gatekeeper prompts appear on first launch of a portable path, read the publisher text carefully and prefer assets that came from the Genymobile/scrcpy Releases list you opened yourself.

Frequently asked questions
Where do I download?
Prefer GitHub Releases for Genymobile/scrcpy when you need screen mirroring archives today. Use scrcpy-win64 zip on Windows, brew install scrcpy on macOS, or the linux x86_64 tarball when you want the current tag on Linux desktops.
Is it free?
Yes. scrcpy is Apache-2.0 open source software. GitHub Releases assets for the client have no paywall at all. Paid phone-to-PC suites from other vendors stay separate products with their own commercial seats.
Do I need USB debugging?
Yes for USB screen mirroring on Android. Enable Developer options and USB debugging on the phone, unlock the screen, and accept the authorize prompt when the cable connects to your computer.
