I like the app, but cannot commit to a closed source solution.

I do appreciate the local-data first approach, but that is table stakes, especially for something as personal and sensitive as a knowledge base.

The "free for personal use" is a rug that can be yanked anytime without warning. After having a number of closed source but otherwise free pieces of software do this, I do not want to climb the learning curve, nor do I suggest anyone else do so.

I've recently played with an open source alternative called foam, which builds a similar experience to Obsidian but inside a VSCode workspace. It's a new project, but under active development, and is already pretty close to the base Obsidian experience of notes + backlinks + graphing https://github.com/foambubble/foam/
