I was pretty disappointed that FireFox integrated a service that was proprietary and not even one that was GDPR-compliant.
I have been looking for a hackable alternative to Google Keep. In the past, Pinboard.io had served me well, but now I am looking for something more. I want not just to store bookmarks, not just to archive web pages, but really to have all these at my fingertips for analysis. I want to shift the balance I have between consuming new information and munging on the information that's already come my way.
Polar seems to be a great alternative because it's a computer application that's 100% self-hosted. I would like something that could be run in a federated way, like Mastodon, but this is still _very_ nice. Since I own the data, I'm not worried about any limitations. I especially like that various forms of cloud sync are supported (looking at you, Syncthing).
I see Electron bashed on HN from time to time. I have no opinion about it personally. Even if there were some noticeable overhead, the capabilities this offers are probably worth it.
Super exciting. I'll give it a go.
