Open Source Windows Screen Capture Software

Ksnip is a Qt based cross-platform screenshot tool that provides many annotation features for your screenshots.

Dayon! is an open source remote desktop and assistance solution. It is easy to use, secure, requires no registration and is free for personal and commercial use!

Gladivs SC allows you to take screenshots from all monitors in your system. You can choose what monitors you want to capture from. You only have to select a destination folder for the captures and press the [Print Screen] button to perform captures. Now it's very simple. Also you can capture a region in your monitor. In this new version you can choose the destination of the capture directly from an options window that appear after screenshot is taken. Note that Oracle JRE 8 or higher is required. If you don't want to use Oracle JRE 8, you can use OpenJDK instead, but you need to install as a prerequisite the OpenJFX libraries from OpenJDK. You can install this library from the package manager of your system. In the official website https://gladivs.com you can find more information and a manual. Feel free to comment if you have any suggestion, bug, or any other question.
