SilverBullet: A Programmable, Self-Hosted Knowledge Base
SilverBullet is for users who want a self-hosted Markdown knowledge base rather than a basic notes editor. It adds links, queries, tasks, and Lua extensibility, while requiring careful deployment and maintenance planning.
What it does
SilverBullet is an open source personal knowledge database built around Markdown. It runs in a browser and can be self-hosted. Content is kept as a collection of Markdown pages in a Space. Users can navigate with a page picker or connect pages through wiki-style bidirectional links.
This makes it more than a plain text editor. The project combines live-preview editing, bidirectional links, a built-in database, and the SLIQ query language. Its README also lists outlining tools, tasks, and Objects, so the same space can support everyday notes as well as more structured information management.
Who it suits
SilverBullet is a good candidate for people who prefer Markdown, want browser-based editing, and would rather control where their knowledge base is hosted. It is especially relevant to users who want to gradually automate personal workflows. Space Lua can dynamically generate content and can be used for custom commands, page templates, and widgets.
Programming is not required for the basic workflow. Markdown, live preview, links, and page navigation can be used on their own. Lua, queries, and extensions become more useful when a user wants deeper customization or automation.
Known capabilities and architecture
According to the repository README, the frontend is written in TypeScript. The editor is built on CodeMirror 6, additional UI uses Preact, and ESBuild is used for frontend builds. The backend is written in Rust and serves the pre-built client, the space/file HTTP API, authentication, and a headless Chrome runtime for server-side Lua.
The repository identifies the project as MIT-licensed and not archived. The official release page lists version 2.10.0 as published on July 28, 2026. That release date should not be treated as evidence of performance, security, or operational stability.
Limits and deployment considerations
Separate using a published build from building the project yourself. The README lists Node.js 24+, npm 10+, and stable Rust as build requirements. A source build therefore requires both JavaScript and Rust toolchains. The repository also includes a Dockerfile, but production deployment details, reverse-proxy configuration, backup procedures, and upgrade policies should be verified against the official installation documentation and the target environment.
The same extensibility that makes Space Lua, plugs, queries, and custom pages attractive also creates maintenance responsibilities. Before adoption, decide who will review scripts, manage extensions, back up the Markdown Space, and handle upgrades. The supplied sources do not establish minimum hardware requirements, a compatibility matrix, performance figures, or the results of a security audit.
The project describes browser access and self-hosting, but the supplied material does not fully document authentication settings, public-internet exposure boundaries, or multi-user behavior. For team use, sensitive data, or an internet-facing deployment, consult the official installation material and test access control, isolation, and recovery procedures before relying on it.
