Tsundoku is a macOS menu bar app for quickly saving bookmarks to self-hosted and cloud-based bookmarking services. Press a global hotkey from anywhere to capture the URL and title from your active browser window. Tags auto-complete from your service, and duplicate URLs are flagged before submission. Supported services include Linkding, Raindrop.io, Wallabag, Shaarli, LinkAce, and Karakeep. Works with Safari, Chrome, Arc, Brave, Edge, Opera, Vivaldi, and more. No browser extension required. The entire workflow is keyboard-driven: hotkey to open, type tags, enter to submit. Under 2 MB.
