Unofficial opensource Slack client for Sailfish.

SailSlack is a fork of Slackfish by Markuss Sammallahti. It has been fixed to work with the current Slack API and improved to handle larger teams, support multiple teams and various other smaller fixes and enhancements.

This is still an alpha-quality software, do NOT rely on it for work!


  • multiple teams support
  • channels, private chats and multi-user chats
  • real-time messaging and notifications
  • sending messages and images
  • display sender's detailed profile

Currently not implemented/broken

  • joining channels and chats from the app
  • viewing and replying to threads (you see all the messages but as a flat list)
  • reacting to messages
  • starring channels, messages etc.
  • creating reminders
  • search
  • message deletion or editing from the app

Is there anything I can do to help get this app Slack-approved? The Blackberry app is still going (and it's very rudimentary), so presumably the bar isn't very high. It would be great to be able to use this app instead of having to install the Android version which doesn't integrate very well.

Running the latest SailfishOS ( on Sony Xperia X. Sailslack doesn't render the login page correctly. The text fields and buttons are there, but text is missing. This is the same problem as in Slackfish.

Its impossible to login using this app. Can I request the developer to fix this issue?

Can't allow Sailslack to access my slack information. It says that: "This app hasn't been reviewed or approved by Slack"

Do you plan to add a deamon?

Eventually, yes. No roadmap yet, though.

Image upload isn't working. It loads forever and never completes.
