ScudCloud: unofficial Linux Slack client

Update: Slack now has an official client for registered teams.

If you haven’t heard about it, Slack is an online collaboration service for running the daily activities in a company. It has messaging, chat rooms, tagging and other collaborative features to work as a team. Everything can be searched from a single search box. However, the strongest feature is the integration of third-party services like Dropbox, Google Drive, GitHub, Google+ Hangouts, Enchant, Twitter and so on. There are tons of them already!

Unfortunately, Slack doesn’t have an official client for Linux. But how could the OS developed by hackers be left behind? Developer Rael Gugelmin Cunha has written ScudCloud, an unofficial Linux client for Slack. ScudCloud is written in Qt & Webkit to render the web version of Slack, but adds desktop integration using  the QWebkit-Native bridge. ScudCloud integrates best with Unity at the time of writing.


  • Multiple teams support
  • Native system notifications
  • Count of unread direct mentions at launcher/sytray icon
  • Alert/wobbling on new messages
  • Channels quicklist (Unity only)
  • Optional “Close to Tray”


To install ScudCloud on Ubuntu, run:

$ sudo apt-add-repository -y ppa:rael-gc/scudcloud
$ sudo apt-get update
$ sudo apt-get install scudcloud
