Briefkasten

Briefkasten is an open-source, self-hosted bookmarking application that stores bookmarks in any Prisma-compatible database. It provides a modern web UI and tools to save, organize and search bookmarks while supporting OAuth and email magic-link authentication.

Key Features

• Save bookmarks via a browser extension, drag-and-drop, or REST API
• Automatic title and description extraction when saving URLs
• Organize bookmarks by categories and tags with multiple list/views
• Import and export bookmarks in standard HTML format
• Background job to fetch bookmark images and enrich metadata
• Keyboard shortcuts and multiple UI views for fast navigation
• Full-text search across saved bookmarks
• OAuth and email magic link authentication support
• Works with any Prisma-compatible database (Postgres, MySQL, SQLite)
• Docker and docker-compose support for easy local deployment

Use Cases

• Personal bookmark vault for managing links, articles and resources across devices
• Team or small-group shared collection of reference links and documentation
• Migrating and consolidating bookmarks from browser exports into a searchable database

Limitations and Considerations

• The project provides a v2 beta; the maintainer has warned that beta database instances may be reset during migration from v1 to v2
• Image storage is not built into the database; an external object store (S3-compatible or provider SDK) is recommended for bookmark images
• OAuth requires configuring provider credentials; initial setup requires a Prisma-compatible database and appropriate environment variables

Briefkasten is a straightforward, developer-friendly bookmarking solution focused on portability, searchability and extensibility. It is suitable for individuals and small teams who prefer a self-hosted bookmark manager with integrations for modern deployment workflows.
