Elegant Facebook Messenger desktop app

Caprine is an unofficial and privacy-focused Facebook Messenger app with many useful features.

Caprine is feature complete. However, we welcome contributions for improvements and bug fixes.



*macOS only


macOS 10.10+, Linux, and Windows 7+ are supported (64-bit only).

Download the latest version on the website or below.


Download the .dmg file.

Or with Homebrew: $ brew install caprine


Download the .AppImage or .deb file.

Arch Linux: pacman -S caprine


sudo dnf copr enable dusansimic/caprine
sudo dnf install caprine

Also available as a snap.

The AppImage needs to be made executable after download.


Download the .exe file.

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


Dark mode

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

Hide Names and Avatars

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.

Mute desktop notifications

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

Hide notification message preview

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

Prevents link tracking

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

Jump to conversation hotkey

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

Compact mode

The interface adapts when resized to a small size.

Desktop notifications

Desktop notifications can be turned on in Preferences.

Always on Top

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

Work Chat support

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

Code blocks

You can send code blocks by using Markdown syntax.

Background behavior

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.

Quick access to conversations from the Dock menu (macOS only)

Touch Bar support (macOS only)

Custom languages for spell-check (Not for macOS)

Users can select supported languages from Conversation Spell Checker Language.

macOS detects the language automatically.

Custom styles

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.

Menu Bar Mode (macOS only)

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.
