Been using it for a while and really like it, just really wish it would get an option to combine edit and view mode to work on things directly.

As far as I know it’s not open source either, which I don’t mean to be the Stallman-type, but is kind of a deal breaker for me.

I wrote my own, if it ever gets to a point of not being terrible I will open source it as a not-as-pretty FOSS alternative.

I think the second brain notion is very powerful though, regardless of platform.

Another tool to look at might be Dendron[1]. It's a VS Code plugin with similar functionality to Obsidian (according to the docs, it actually evolved from being a standalone app like Obsidian into the plugin form). My understanding is the client/plugin are FOSS, and the developer plans to implement some (optional) server-side functionality to fund ongoing development.

Neither had I, and I’m excited to try Obsidian.

I was really looking for a local Roam Research equivalent and org-roam didn’t fit my style.
