Download the latest version on the website or below.

Download the .dmg file.

Or with Homebrew: $ brew install caprine

• Download and install deb-get.
• Run deb-get install caprine.

Note: deb-get is 3rd party software, not to be associated with apt-get.

Run the following command to add it:

wget -q -O- https://raw.githubusercontent.com/sindresorhus/caprine/main/packages/deb/addRepo.sh | sudo bash

Alternatively (for advanced users):

# Add the repository
echo "deb [trusted=yes] https://apt.fury.io/lefterisgar/ * *" > \
/etc/apt/sources.list.d/caprine.list

# Update the package indexes
sudo apt update

# Install Caprine
sudo apt install caprine

For Fedora / RHEL:

sudo dnf copr enable dusansimic/caprine
sudo dnf install caprine

For openSUSE:

• Create a new file in /etc/zypp/repos.d/caprine.repo.
• Copy the contents of this file and paste them into the file you just created.

Alternatively use the following one-liner:

curl -s https://copr.fedorainfracloud.org/coprs/dusansimic/caprine/repo/opensuse-tumbleweed/dusansimic-caprine-opensuse-tumbleweed.repo | sudo tee /etc/zypp/repos.d/caprine.repo

Download the .AppImage file.

Make it executable:

chmod +x Caprine-2.xx.x.AppImage

Then run it!

Fedora Silverblue, Fedora Kinoite, EndlessOS, CarbonOS and other immutable distributions only support Flatpak and/or AppImage.*

Note: On some distributions Flatpak must be pre-configured manually.

For taskbar notification badges to work on Windows 10, you'll need to enable them in Taskbar Settings.

You can toggle dark mode in the View menu or with Command d / Control d.

You can prevent others from looking at who you're chatting with by enabling the “Hide Names and Avatars” feature in the “View” menu or with Command/Control Shift n.

On macOS, you can toggle the window vibrancy effect in the View menu.

You can choose to prevent people from knowing when you have seen a message and when you are currently typing. These settings are available under the Caprine/File menu.

You can quickly disable receiving notifications from the Caprine/File menu or the Dock on macOS.

You can toggle the Show Message Preview in Notification setting in the Caprine/File menu.

Links that you click on will not be tracked by Facebook.

You can switch conversations similar to how you switch browser tabs: Command/Control n (where n is 1 through 9).

The interface adapts when resized to a small size.

Desktop notifications can be turned on in Preferences.

You can toggle whether Caprine stays on top of other windows in the Window/View menu or with Command/Control Shift t.

Support for Work Chat: Messenger for Workplace. You can switch to it in the Caprine/File menu.

You can send code blocks by using Markdown syntax.

When closing the window, the app will by default continue running in the background, in the dock on macOS and the tray on Linux/Windows. Right-click the dock/tray icon and choose Quit to completely quit the app. On macOS, click the dock icon to show the window. On Linux, right-click the tray icon and choose Toggle to toggle the window. On Windows, click the tray icon to toggle the window.

Note that you can change the behavior of Caprine so that the app closes when the window is closed. For this, you'll need to go to the settings and click on Quit on Window Close.

Users can select supported languages from Conversation → Spell Checker Language.

macOS detects the language automatically.

Advanced users can modify the colors/styles of Caprine. Click the menu item Caprine/File → Caprine Settings → Advanced → Custom Styles and a CSS file will open up in your default editor.

You can enable Show Menu Bar Icon in the Caprine Preferences menu to have a Caprine icon in the menu bar. The icon will indicate when you have unread notifications and you can click it to toggle the Caprine window. You can also toggle the Caprine window with the global shortcut Command Shift y.

You can also remove Caprine from the Dock and task switcher by clicking Hide Dock Icon menu item from the menu bar icon. There will then no longer be any menus for the window, but you can access those from the Menu item in the menu bar icon menu.

On macOS, you can change these in the System Preferences and you can even add your own keyboard shortcuts for menu items without a predefined keyboard shortcut.

The main app interface is already localized by Facebook. The app menus are not localized, and we're not interested in localizing those.
