Welcome to Gotcha!

Gotcha! is a small utility for OS/2, eComStation, and ArcaOS which allows for the capturing of windows, window interiors, parts of the screen, or the entire desktop, and saving such images to disk or to the clipboard (in several file formats).

It has options for serial capture (automatically taking a capture every n seconds) and batch mode (take a capture, save, and exit).

The original author, Thorsten Thielen, wrote Gotcha! mainly because all other screen capture programs for OS/2 that he found at the time were either quite outdated, part of another (usually large) program, buggy, and/or not free.

Current Status


  • Gotcha! (as available here) is open source software released under the GNU General Public License version 2.
