Peek
Simple animated GIF screen recorder with an easy to use interface
...With Peek, you simply place the Peek window over the area you want to record and press "Record". Peek is optimized for generating animated GIFs, but you can also directly record to WebM or MP4 if you prefer. Peek is not a general purpose screencast app with extended features but rather focuses on the single task of creating small, silent screencasts of an area of the screen for creating GIF animations or silent WebM or MP4 videos. Peek runs on X11 or inside a GNOME Shell Wayland session using XWayland. Support for more Wayland desktops might be added in the future.
