What is it?

Flameshot is a screenshot application for Linux, Windows and macOS. Running the flameshot command starts a background instance, and commands such as flameshot gui open an interactive capture overlay where you select an area and draw on it before saving or copying the result.

The in-capture editor offers tools for pencil, line, arrow, rectangle, circle, marker, text, selection and pixelation, along with undo and redo. Captures can be saved to a chosen path, copied to the clipboard, opened in another app, or uploaded to Imgur. Full-screen, single-screen and delayed captures are available from the command line.

Settings can be changed through a graphical configuration window, the flameshot config command, or the flameshot.ini file. Global hotkeys are set up per desktop environment, with documented steps for KDE Plasma, GNOME, XFCE and Fluxbox, and Wayland compositors and minimal X11 window managers have separate setup guides.
