Satty: Modern Screenshot Annotation.

Satty is a screenshot annotation tool inspired by Swappy and Flameshot.

Satty has been created to provide the following improvements over existing screenshot annotation tools:

• very simple and easy to understand toolset (like Swappy)
• fullscreen annotation mode and post shot cropping (like Flameshot)
• extremely smooth rendering thanks to HW acceleration (OpenGL)
• working on wlroots based compositors (Sway, Hyprland, River, ...)
• minimal, modern looking UI, thanks to GTK and Adwaita
• be a playground for new features (post window selection, post paint editing, ...)

Install

Thanks to our package maintainers, Satty is available for many distributions on Linux and BSD:

Arch Linux

You can get the official Arch Linux package from the AUR:

pacman -S satty

Gentoo

You can get the Gentoo package from the Guru overlay:

eselect repository enable guru

Satty is available in Alpine Community. You can install it by uncommenting the community repo in /etc/apk/repositories and then run:

apk add satty

Prebuilt Sources

You can download a prebuilt binary for x86-64 on the Satty Releases page.

Usage

Start by providing a filename or a screenshot via stdin and annotate using the available tools. Save to clipboard or file when finished. Tools and Interface have been kept simple.

All configuration is done either at the config file in XDG_CONFIG_DIR/.config/satty/config.toml or via the command line interface. In case both are specified, the command line options always override the configuration file.

Configuration File

[general]
# Start Satty in fullscreen mode
fullscreen = true
# Exit directly after copy/save action
early-exit = true
# Select the tool on startup [possible values: pointer, crop, line, arrow, rectangle, text, marker, blur, brush]
initial-tool = "brush"
# Configure the command to be called on copy, for example `wl-copy`
copy-command = "wl-copy"
# Increase or decrease the size of the annotations
annotation-size-factor = 2
# Filename to use for saving action. Omit to disable saving to file. Might contain format specifiers: https://docs.rs/chrono/latest/chrono/format/strftime/index.html
output-filename = "/tmp/test-%Y-%m-%d_%H:%M:%S.png"
# After copying the screenshot, save it to a file as well
save-after-copy = false
# Hide toolbars by default
default-hide-toolbars = false
# The primary highlighter to use, the other is accessible by holding CTRL at the start of a highlight [possible values: block, freehand]
primary-highlighter = "block"
disable-notifications = false

# Font to use for text annotations
[font]
family = "Roboto"
style = "Bold"

grim -g "$(slurp -o -r -c '#ff0000ff')" -t ppm - | satty --filename - --fullscreen --output-filename ~/Pictures/Screenshots/satty-$(date '+%Y%m%d-%H:%M:%S').png

Hyprland users must escape the # with another #:

grim -g "$(slurp -o -r -c '##ff0000ff')" -t ppm - | satty --filename - --fullscreen --output-filename ~/Pictures/Screenshots/satty-$(date '+%Y%m%d-%H:%M:%S').png
