Konode syncs your browser to storage you already own. Bookmarks, open tabs, history and your installed-extension list go straight from your browser to your own Google Drive, a private GitHub repository, or any WebDAV server. There is no Konode server in the middle, no account to create, and no telemetry. Optional end-to-end encryption is one choice away.

It works on any Chromium browser and on Firefox, and it is free and open source (MPL-2.0).

Konode is free and stays free. Support here goes toward the time that keeps it maintained: answering bug reports, testing new browser versions, and the store fees that come with publishing it.
