I mean Trilium is fantastic app, lots of potential but the developer is struggling on his own, maybe it's because it's younger than logseq or maybe because is open source compared to obsidian. I think it's the best note-taking/knowledge-base/second-brain i know it virtually could link everything you posses toghter to create a gigantic wiki, so much potential. Plus it has its own self hostable syncing server and web app. Guys give it a look and tell me what you think
I can't compare, I never used Zim, sorry. If I remember correctly it is, I personally got it with flatpack.
Ah, if it's only available on flatpaks, that's why few people know about it.
Flatpak is a very insecure method to download software BTW, you probably should avoid it
Edit: It's curious that I'm getting downvoted for stating a fact. It seems a lot of flatpak users don't understand security. But that's kinda the point: even the flatpak developers don't understand the difference between integrity and authenticity
Flatpak currently does not provide authenticity, and one developer made it clear that he doesn't understand why that matters in the above ticket that requested signatures of packages back in 2016. It's been 7 years and still they haven't fixed this. I don't think the flatpak team understands or cares about security.
