A Wayland screenshot tool built for multi-monitor setups (Hyprland; partially sway), with Photoshop-like annotation layers and an editable history.
- Multi-monitor overlay: every screen freezes and dims; the one under the cursor glows. Pick an area, a window (click) or the whole screen (double click / Enter); a pixel loupe shows coordinates and color.
- Tools: brush, highlighter, line, arrow, rectangle, ellipse, text, blur/pixelate, numbered marks (circle/square/diamond; drag a mark away and its arrow stays pinned to the original spot) and a magnifier callout with leader lines.
- Layers: blend modes, opacity, visibility, reordering, multi-select, undo/redo.
- Editable history: every shot keeps the full capture plus its layers, so marks, text and even the crop can be changed later in the editor.
- Tray icon, live clipboard (re-copies the final image after every edit), pinned always-on-top shots, 9 interface languages.
Grab kadr-*.pkg.tar.zst from Releases and run
sudo pacman -U kadr-*.pkg.tar.zst, or build it yourself:
git clone https://github.com/sendement/kadr && cd kadr/packaging/arch
makepkg -si
kadr tray # tray icon: click — screenshot, middle click — history, right click — menu
kadr # select an area (overlay on every screen)
kadr -d 3 # same, after a 3 s delay
kadr screen # instant shot of the screen under the cursor -> clipboard + history
kadr history # history gallery
kadr edit [ID|last] # open a history item in the layer editor
kadr --lang de ... # override the interface language for one run

The system language is used automatically (LANGUAGE / LC_ALL / LC_MESSAGES / LANG);
unsupported languages fall back to English. Pick one explicitly from the tray menu
(Language) or set "language" in the config. Translations live in kadr/locales/<code>.json,
keyed by the English source string.
V pointer · P brush · H highlighter · L line · A arrow · R rectangle · E ellipse · T text · M numbered mark · B blur/pixelate · Z magnifier · Tab layers · wheel — tool width/size · Shift — 15° steps / square · Ctrl+Z / Ctrl+Shift+Z · Del · Ctrl+D duplicate · Ctrl+[ / ] order · arrows — nudge (Shift ×10) · Enter/Ctrl+C copy · Ctrl+S save · Ctrl+E editor · Esc cancel.
Selecting: drag — area, click — window, double click / Enter — whole screen. With a selection, a single click outside does nothing, double click outside selects the whole screen, drag outside starts a new selection.
Marks: click — place; click+drag — place and pull out with an arrow; dragging later moves the mark while the arrow stays pinned to the original spot (Ctrl+drag moves both).
Magnifier: select the area, drag the copy aside, resize it by its corners; dragging the source re-targets what is magnified.
