About SilverBullet

SilverBullet is a personal knowledge base that runs in the browser and is hosted on your own server. Your content is stored as Markdown pages grouped into a Space, which you can open from a page picker as in a classic notes app, or reach through two-way wiki-style links. The project describes itself with a tongue-in-cheek phrase as a notes app on steroids.

What sets it apart is that notes can be programmed. A live-preview editor is paired with an integrated database and query syntax, and a Lua scripting environment called Space Lua lets you extend the system, build custom views and automate tasks. Repository topics highlight knowledge management, personal knowledge management, note taking and end-user programming.

SilverBullet is written in TypeScript and licensed under MIT. Because it is designed for self-hosting and plain Markdown files, it suits individuals and small teams who want a private, hackable wiki and are comfortable with a little scripting. There is no hosted service from the project.
