I was looking for a Zettelkasten note taking app which would 1. work on laptop and phone 2. wouldn't have any vendor lock-in and 3. wouldn't go away if a single company folded - couldn't find one, so I started writing one. I'm writing it as a PWA to make it available ~everywhere and planning to use dropbox/google drive/whichever as the backend so users will have full control over their notes.

I'm amazed how much you can accomplish with modern web tech stack. I can literally bypass any need for a server by having the user connect to their cloud! I can just create a PWA and publish it as an app! On the downside I've learned that some features are hard to implement with above requirements using PWAs though. For example, only Chrome supports some level of filesystem access, so storing notes locally would mean discriminating by browser, which I don't feel great about.
