SilverBullet is a free, minimalist open-source application for note-taking and information organization. It is available for Windows, macOS, Linux, Android, iOS, and as a web service.

Main Features of SilverBullet

SilverBullet is designed for those who want complete control over their own knowledge. It emphasizes locality, privacy, and flexible organization of information. The minimalist design directs the user’s focus to the content itself and serves as a simple version of a personal wiki.

SilverBullet is a self-hosted web application that can be installed as a local server or a cloud-based one. After installation, it is necessary to create or select a folder where the collection of notes will be stored. In SilverBullet terminology, this folder is called a Space. After an offline period, once the connection is re-established, notes are automatically synchronized.

SilverBullet uses Markdown syntax, so created files have the .md extension and can easily be used in other applications. Each note can have tags and headers. The created content can be quickly connected using internal wiki-style links. Linked terms are automatically indexed and displayed as part of a knowledge graph.

What makes SilverBullet special is its approach that treats each note as part of a larger database that can be queried and analyzed. The queries generate clean output, in tables or inline text, using templates. For advanced real-time search, users can filter by expressions, tags, content, and links.

Functionality can be extended by embedding blocks consisting of tables, to-do lists, calendars, or code snippets. Additional capabilities can be created through user-defined scripts in Lua and JavaScript programming languages. There is no dedicated mobile application, but it can be accessed through a mobile web browser, since SilverBullet is a progressive web app (PWA).

SilverBullet in Practice

The application is developed by an active community on the GitHub platform. Installation files are available on the page linked by the Download button below. There are two installation methods: using an executable file or via Docker. The application is then started with the following command:

./silverbullet /path/to/your/space

After launching, a local server opens, which can be accessed through a web browser by default at:

http://localhost:3000

Users should be aware of certain limitations that come with SilverBullet. It is not a replacement for comprehensive applications like Notion or Obsidian. It lacks automatic integration with commercial cloud services such as OneDrive or Google Drive. Basic knowledge of Markdown syntax is required to use it effectively. There is no rich GUI or true WYSIWYG mode.

SilverBullet has very modest hardware requirements and can run even on older computers. The application does not collect user data and does not require registration to start working. It is aimed at advanced users who make no compromises when it comes to privacy, such as developers and researchers of various fields, who prefer working in a text-based environment.
