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)

  • 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)
  • Favorite Rooms
  • View Source
  • Experimental emoji verification (New)
  • Rooms search (New)
  • 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.

Emoji verification instructions

Currently, emoji verification is highly experimental. It can only be started from another device, such as Element, and you must be on the Rooms list to receive the emoji verification flow.


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.

kempertom's picture

Are you planning further development of Sailtrix?

HengYeDev's picture

Yes, but slowly...

jetset's picture

works good on my 10ii. thanks

objectifnul's picture

Version 1.3.8 okay, except if I need to log in again: must downgrade to v1.3.7 to do so (Sfos v3.4.0.24)

zipotron's picture

Hello, the app is not starting anymore after last SFOS update.

HengYeDev's picture

4.4? if so, try adding:


to the /usr/share/applications/harbour-sailtrix.desktop

Patch will be released soon when I find out more about some other compatability issues in 4.4

zipotron's picture

Thanks for this amazing work!

huggymann's picture

app takes no changes anymore: I have a state in my app where the chats, invites and room will never change. When deleting they disappear until next app start, it is all there again. Also the invites, if accepted, do not go to poeple or rooms but stay as invite. Is there a way to do a clean install and remove all config files? i couldnt find anything for harbour-sailtrix

HengYeDev's picture

Please go into settings and click clear cache.

huggymann's picture

...the solution was right there :D Thanks!

With SFOS 4.3 (released in EA yesterday), `` is missing, as OpenSSL 1.0 was (finally) removed. A rebuild with newer SDK should fix it.

HengYeDev's picture

I have fixed it by statically linking but haven't merged yet. Download artifacts from

lpr's picture

that is bad practise, openSSL1.1.1 is available for all armv7 devices here on openrepos so you should use dynamic linking openssl1.1.1 while remaining SFOS3.4 compatible in respect to other parts GUI/silica/etc.

slava's picture

Yes, it's a bad practice, I absolutely agree with that but it's the only way to avoid non-standard dependencies, unfortunately. You download the rpm, tap on it and it gets installed, that's my personal requirement.

Breaking backward compatibility is a bad practice, that's what it boils down to. That's what created the problem in the first place, and the rest is a consequence of that.

lpr's picture

but it is as simple as that. Just tap install-button on storeman and install openssl1.1.1

slava's picture

That means dependency on storeman. Some people may be ok with that, but I don't want even that. When package has dependencies, removing the app leaves (by default) dependencies around, I don't like it. If nothing else it may mean trouble next time you upgrade the OS. I want removal to mean removal.

HengYeDev's picture

It is bad practice but imo for now it's the best way to go without adding confusion for anything...dynamic link builds will still be available on chum. Foil notes did it

lpr's picture

just tell openssl1.1.1 in requirements section , maybe with link or without but it is there

slava's picture

And make the build incompatible with systems which don't have

delocoyo's picture

Done. Thanks for the help. Keep rocking the app @HengYeDev

delocoyo's picture

Hello. Sorry for my little knowledge , but how and where can I find the homeserver url for element to be use in the app? Thanks

HengYeDev's picture

It's the second part of your matrix user id. For example, my matrix username is, so my homeserver URL would be

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.

meemorph's picture

@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.

HengYeDev's picture

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.
