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.

Made for Matrix


  • 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)
  • Timestamps of messages are displayed
  • Sending messages
  • Sending messages in reply
  • Editing messages
  • Deleting messages
  • Starting direct messages
  • Ignoring and unignoring users
  • Viewing and downloading of images
  • Viewing of audio and video
  • Display of member events
  • Downloading files
  • Sending files
  • Accepting invites
  • Public room directory
  • Creating Rooms
  • Sorting by Activity or Alphabetically
  • Launching and matrix:// links (at present, you need to use the "Nheko" button at
  • Notifications
  • 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

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 or a bug to be fixed.

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

A note on notifications

Sailtrix >= 1.3 supports notifications. They may eat battery as it causes the phone to wake up every 30 seconds - you can change this interval in the settings. You can also disable them there. Every time you restart your device, you will need to launch Sailtrix to start the notifications. Then, you can close the app.


Pipeline status

Development status and source code are available on GitLab ( - feel free to fork and submit merge requests.


I'm not always available for support and it may take a few hours or days for me to respond. Discussion will take place in the Sailtrix matrix room:


Please note that to prevent strange occurrences, one should execute "killall harbour-sailtrix" to stop the daemons before updating.

Wow, this evolves. What a fantastic job.
Small bug I noticed: If I edit my msg in Elements app f.e. 4 times, it shows uo 4 times in sailtrix.

@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.

Please try the new build from the artifacts here:

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.

Does not work on 3.4: harbour-sailtrix: error while loading shared libraries: cannot open shared ob
ject file: No such file or directory

HengYeDev's picture

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.
