ZeroNote

ZeroNote is an open-source, offline-first unified app that replaces your password manager, bookmark manager, notes app, and 2FA authenticator with a single encrypted note-taking system powered by smart tags, where everything is stored locally on your device with zero-knowledge encryption and optional peer-to-peer or S3 sync. Maintained by besoeasy on GitHub, where it has earned 54 stars from the community.

It's actively developed around bookmark-manager, bookmarks, encryption, and is a solid reference for anyone building with these tools.
