I really wish a country like China would launch a globally aimed social media site that has good multilingual support and allows anyone to sign up. Might just be a disaster or never take off, but it's so lame to just switch between American operated social media sites.
Telegram is the only non-US based one I know of. At least the only big one known for not being American.
I wish there was something nice like that too.
In the server world that would usually involve doing something like sending the journal data to Elasticsearch using an Elasticsearch integration. But that involves setting up an Elasticsearch server and Kibana and so on which is very unwieldy for a desktop computer. It does work pretty well though in terms of filtering. But it also stores the data internally in indexes to speed up search.
Of course journald has a seemingly simple C API but writing code is a lot of work. There are probably API bindings for various languages.
