About Flameshot

Flameshot is screenshot software with a customizable look and an in-app editor, so you can capture an area of the screen and mark it up before saving or sharing. It is built with Qt in C++, runs on Linux, Windows and macOS, and is released under the GPL-3.0 license. The project aims to be easy to use while still offering configuration options.

Running the flameshot command starts a background instance, with a tray icon on desktops that have a tray, and further commands trigger captures. Examples in the README cover GUI captures, delayed captures for hover tooltips, full-screen captures to a custom path, copying to the clipboard, and printing PNG data. A DBus interface and the ability to upload to Imgur are included. The documentation has setup notes for Windows, Hyprland, Sway, minimal X11 window managers and keyboard shortcuts on KDE, GNOME, XFCE and Fluxbox.
