Seer Alternatives
Seer is described as 'This is a quick look tool for Windows. Acts just like the one in OS X , but Seer is more powerful and faster' and is an app in the os & utilities category. There are more than 10 alternatives to Seer for Linux, Mac, Windows and Linux Mint. The best alternative is QuickLook, which is both free and Open Source. Other great apps like Seer are Preview, Eye of GNOME, Xviewer and Viso.
Seer alternatives are mainly Image Viewers but may also be PDF Readers. Filter by these if you want a narrower list of alternatives or looking for a specific functionality of Seer.
