SYNOPSIS

flameshot [subcommand] [options]

Flameshot is a powerful yet simple screenshot tool for Linux featuring an intuitive GUI for region selection and built-in annotation capabilities. It supports drawing shapes, adding text, arrows, and markers directly on screenshots before saving.
The tool integrates with the system tray for quick access and supports both X11 and Wayland display servers. Screenshots can be saved to files, copied to clipboard, or uploaded to image hosting services. A D-Bus interface enables scripting and integration with other applications.

HISTORY

Flameshot was created by lupoDharkael and first released in 2017. It was designed as a modern alternative to older screenshot tools, drawing inspiration from Greenshot (Windows). The project is written in C++ using the Qt framework and has become one of the most popular screenshot utilities in the Linux ecosystem.
