I currently use primarily Logseq with a little Obsidian because it’s just a really pleasant text editor and Zettlr for long form writing and research. The nice think about keeping it all Makrdown is that I can use any of them depending on what features/UI I need.

Logseq does have the web editor but it’s more of a demo (it’s literally called demo.logseq.com) but it gives you the full vanilla feature set as long as you connect a local directory. I use Logseq Sync just because I was paying to support the team anyway, and it’s worked very well so far. Just ran into an issue where my laptop with most of my notes broke and so I made a portable version of the app to put on a USB and work on a library computer and it ran and connected to my Logseq Sync remote graph surprisingly seamlessly.
