flameshot-org/flameshot

Overview\nFlameshot is a C++/Qt screenshot application for Linux, Windows and macOS. It opens a capture window where you drag a selection, then annotate with pencil, line, arrow, rectangle, circle, marker, text and pixelate tools before copying or saving. It also exposes a CLI and a DBus interface, plus an optional Imgur upload action. It targets desktop users who want a lightweight, scriptable screenshot workflow rather than a full image editor.\n\n## Quick Start\nInstall from your system package manager where available. For Debian/Ubuntu:\n\nshell\nsudo apt install flameshot\n\n\nArch and Fedora users can use pacman -S flameshot or dnf install flameshot. Windows users can use scoop install flameshot, and macOS users have MacPorts and a Homebrew tap. Prebuilt packages are also on the release page.\n\nOnce installed, take a GUI capture:\n\nshell\nflameshot gui\n\n\nSelect an area, annotate it, then press Ctrl+C to copy or Ctrl+S to save. For full-screen capture with a custom path and delay:\n\nshell\nflameshot full -p ~/myStuff/captures -d 5000\n\n\nThe README suggests binding flameshot gui to a keyboard shortcut in your desktop environment.\n\n## Usage Constraints\nFlameshot works best in a desktop environment with D-Bus; minimal window managers may need extra portal or legacy X11 configuration. Wayland support for GNOME and Plasma is described as experimental, and Hyprland/Sway/wlroots users have a separate setup document. On GNOME, the tray icon requires the AppIndicator extension. On Windows, flameshot.exe does not print console output; use flameshot-cli.exe for CLI output. macOS builds may need a first-launch approval or quarantine removal step. The main code is GPL-3.0, and the project states it does not transfer data unless the user requests it.\n\n## HotRepo's take\nFlameshot has a long-running footprint: a 2021 Hacker News thread called it a “Superb Screenshot Tool” with 335 points, and a January 2026 thread drew 281 points and 113 comments. In the 2026 discussion, one user reported that Flameshot does not capture HDR brightness on modern HDR displays, while another replied that the app is Linux-first and HDR support on Linux is limited. On the daily C++ list for 2026-11-10 it ranked third with 23 new stars. The recurring discussion shows an established desktop utility with active users, but HDR capture remains a documented gap for some hardware.
