Sailtrix is a matrix client for SailfishOS supporting end-to-end encryption among many other features. Currently in beta state and is intended to become more feature-rich over time.


  • Logging in with username and password
  • Reading the past messages in a room (currently limited to loading 30 at a time)
  • Messages with basic formatting can be read (bold, italic, etc)
  • Sending messages
  • Sending messages in reply
  • Editing messages
  • Deleting messages
  • Starting direct messages
  • Ignoring and unignoring users
  • Viewing and downloading of images (New)
  • Sending files  (New)
  • Basic end-to-end encryption support (Late Alpha State - please do not use when security is important, it is more than a proof of concept but not in a beta state yet)
  • All sensitive information including messages are encrypted at rest with Sailfish Secrets (New)

Sailtrix features an encrypted message cache to load only the newest messages when you open a room, improving its performace significantly. However, it can corrupt at times, and may cause strange behavior, such as the wrong avatars being displayed. It is easy to clear this cache in the settings.

There are currently many features that are not implemented. Please see the GitLab issue tracker for an incomplete list. Feel free to add to it if you want a feature to be implemented.

Sailtrix has been tested to be working on Sailfish 3.4 and newer.

@lpr this was a little helpful, agter reboot I can start sailtrix. But cannot enter credentials, only cancel / Login are usable all other GUI elements are printef at top edge over each other and unusable. This piece of software maybe usable above 4.0 only.

still the same, added comment on gitlab at issue 'SFOS 3.4 show stoppers'. Problem with 'width: page.width', looks like page.width could not be referenced.

Issue open here:
In SFOS 4.0 libcrypto was updated to 1.1 and the packages were built with 4.1 sdk

Hi, with the 3.4 release of sailfishos i have got an error with libcrypt. Do you support this release ?

HengYeDev's picture

Best way is to try it :) It should work as libcrypt is not used, only libcrypto, and only one function as of now (RAND_bytes) is used now.
