Introduction

vaultmd gives your Bun app a programmatic data layer over a folder of markdown notes. Your .md files on disk stay the single source of truth; vaultmd maintains a rebuildable bun:sqlite index alongside them so you can query notes by tag or frontmatter, walk backlinks, and run keyword search — all without an editor, sync engine, or background daemon.

It's the engine, not the app: generic vault mechanics only. Personas, domain schemas, and sync logic live in whatever you build on top.

When to use it

You want a queryable layer over plain markdown without adopting Obsidian.
You need backlinks / outbound-link resolution and full-text search over notes.
You're on Bun (≥ 1.1.0) — vaultmd uses bun:sqlite and does not run under Node.
