About

SilverBullet is an open-source, self-hosted, browser-based personal knowledge management platform built on Markdown, local-first principles, and powerful Lua scripting.

SilverBullet is one of the more distinctive PKM products in the current landscape. The official site describes it as a programmable, private, browser-based, self-hosted personal knowledge management platform. It combines Markdown pages, wiki-style linking, local-first PWA behavior, task handling, outlines, tags, queries, and Lua-based programmability. That makes it a strong fit for technical users who want note-taking and knowledge management with more automation and extensibility than mainstream tools provide.
