Other crosshair programs offer a single style or color option, and often don’t allow you to reposition them. CrossOver is a small, unintrusive crosshair overlay which has plenty of configuration options to assist with aiming and vision of your crosshair. CrossOver offers a huge improvement to many games’ default crosshairs for those with colorblindness or contrast issues.

Thanks to Reddit user /u/IrisFlame for the premade library of crosshairs!


macOS 10.10+, Linux, and Windows 7+ are supported.

Download the latest version of CrossOver from the releases page


Download the .exe file. (CrossOver-Setup-x.x.x.exe)


Download the .dmg file. (CrossOver-x.x.x.dmg)


Download the .AppImage or .deb file.

The AppImage needs to be made executable after download.

Because this app is Free and Open-Source, we cannot afford to sign our code. This means Chrome may warn about an untrusted download, this is normal. Click the arrow icon -> Keep to finish downloading. Windows Defender and Mac Gatekeeper will prevent you from running the app the first time.

Windows protected your PC.


“CrossOver” cannot be opened because the developer cannot be verified.

Hidden by fullscreen apps

Currently CrossOver only works with windowed applications, use Windowed Fullscreen mode if your game or application supports it. Windows - []

Sight is deformed or off by 1 pixel

Due to limitations in chrome we are unable to generate sub-pixel graphics, although there may be a way…

Transparency not working

Black window appears behind CrossOver. CrossOver will not hide settings when locked. Crosshair loses opacity (becomes opaque). Linux (debian) - []


An extra big thanks to the crosshair providers, as this wouldn’t be possible without them:
