Briefkasten

Briefkasten is a self-hosted bookmark manager for saving, organising, and retrieving web content. Users can add bookmarks through a browser extension, drag-and-drop, or the Android share menu, with the app automatically extracting titles, descriptions, and preview images. Bookmarks can be grouped with tags and categories, and a full-text search makes it easy to retrieve saved content across a large collection.

The platform supports REST API access, import and export in standard HTML format, and authentication through OAuth providers or email magic links. Data is stored entirely on your own infrastructure, giving you complete ownership and privacy over your reading list.

Briefkasten is aimed at developers and technically-minded users who want a private, customisable alternative to commercial bookmarking services like Pocket and Pinboard, and who are comfortable self-hosting their own applications.
