SilverBullet

An extensible open-source alternative to Obsidian and Roam Research for building a personal knowledge base with live preview and plug-in support.

About SilverBullet

SilverBullet is a note-taking and personal knowledge management tool that runs as a self-hosted web application on Deno. It uses plain markdown files stored on disk and offers a live preview editor with automatic indexing and bi-directional links. The system lets you query your notes dynamically using a built-in expression language, making it more like a local database for your thoughts than a static wiki.

The editor supports syntax highlighting, slash commands, and a plug-in system written in TypeScript that can extend functionality through Deno. SilverBullet works on Linux, macOS, and Windows via Docker or direct Deno deployment. It integrates with Git for version control and can be used through any modern web browser, including mobile devices.

Founded by Zef Hemel, SilverBullet is released under the MIT license and is free for anyone to use or modify. It is best suited for developers and technical users who want full control over their personal knowledge base without relying on a hosted service. The project is relatively new but has gained attention for its speed and extensibility.
