Logseq is at the top of the list and would be the most similar/robust in terms of linking, visualizations and plugins [0]. It’s also open source, and I think a lot of development would shift in this direction if Obsidian ever angered the community.
Roam Research is also conceptually similar but I’ve spent less time digging into the tooling.
I’ve also been keeping an eye on Zettlr and Joplin, but these are not as flexible and their usefulness would depend on how you’re using Obsidian.
I misplaced the link to the repo right, but there was a “universal markdown notes migrator” project I found on GH back when I was evaluating Obsidian that looked promising and the goal was to facilitate movement between tools.
