Has anyone audited/read their code. I found it very suspicous that a company as small as them would be able to deliver software as complex as it was on the face of it. But when I last checked, I guess it hadn't been open sourced yet. Being Latvian, I am skeptical of other Latvians, but in this case, I'm skeptical of running potentialy Kremlin aligned source.
For what it's worth, their server can be hosted on Windows and Linux, so somebody could make a Dockerfile for it. But yeah, in any case I'd double check for any log4j like known vulnerabilities.
