## What it is
SilverBullet is a self-hosted, browser-based personal knowledge management app that stores notes as Markdown pages with wiki-style bidirectional linking, tasks, and a built-in query language. It is programmable via an embedded Lua dialect (Space Lua) for custom commands, templates, widgets, and dynamically generated content.

## Use cases
- self-hosted markdown note-taking app
- personal knowledge base with wiki-style backlinks
- programmable notes with Lua scripting
- manage tasks and outlines in plain markdown files
- run a notes server on a Raspberry Pi
- query and organize notes like a database
- replace Notion or Obsidian with an open-source self-hosted alternative

## When to choose
- you want your notes as plain Markdown files you fully own and self-host
- you want to extend your note system with scripting, custom commands, and queries
- you need a lightweight server that runs on modest hardware like a Raspberry Pi
- you prefer browser-based access across devices from your own server

## When to avoid
- you want a polished offline-first desktop or mobile app without hosting anything
- you need real-time multi-user collaborative editing
- you prefer a no-code tool and don't want to touch Lua or configuration
- you need a hosted managed service with zero setup
