## What it is
CrossOver is a free, open-source desktop application that displays a customizable crosshair overlay on top of any windowed game or application. It offers 530+ built-in sights plus custom image support, multi-monitor duplication, and hotkey controls, using only an external window overlay with no game injection.

## Use cases
- add a crosshair to games that lack one
- use a consistent crosshair across multiple FPS games
- display a custom crosshair image on screen
- show crosshairs on multiple monitors at once
- auto-hide the crosshair when aiming down sights
- get a free alternative to paid crosshair overlay tools

## When to choose
- you want a free, open-source crosshair overlay on Windows, macOS, or Linux
- you need many built-in reticle styles or custom image crosshairs
- you want multi-monitor support and per-display crosshair positions
- you need an overlay that doesn't touch game files or trigger anti-cheat

## When to avoid
- you need full-screen exclusive mode overlays rather than windowed/borderless
- you want aim assistance or game modification rather than a visual overlay
- you require a license-permissive dependency (it uses FSL-1.1-MIT, not pure OSI licensing)
