Alexandrite looks like it requires Docker to run, which unfortunately causes conflicts with our hosting setup. I don't have the time to do a deep dive on it at the moment to see what other options there might be so that one will be on hold for now/indefinitely.
We're also now running the Voyager frontend which is more mobile focused. It can be found here: https://voyager.crazypeople.online/
Hopefully that takes care of your needs. Please let us know if you run into any problems.
