## What it is
Fast Note Sync is an Obsidian plugin that provides real-time, multi-device note synchronization with automatic backup, version history, and shareable links. It requires a companion self-hostable server (fast-note-sync-service) and supports Mac, Windows, Android, and iOS.

## Use cases
- sync obsidian notes across devices in real time
- privately host my own note sync server instead of obsidian sync
- automatically back up my obsidian vault
- restore previous versions of notes or recover deleted notes
- share an obsidian note with a friend via a link
- sync notes between pc and phone seamlessly
- build a personal knowledge base with sync and api access

## When to choose
- you use Obsidian and want real-time, low-friction sync across desktop and mobile
- you want to self-host your note sync for privacy or cost reasons
- you need attachment sync, version history, and trash recovery beyond basic sync
- you want shareable note links or REST/MCP access to build a personal knowledge base

## When to avoid
- you don't use Obsidian as your note-taking app
- you don't want to run or maintain your own server
- you need end-to-end encrypted sync specifically
- you only need occasional manual file sync rather than real-time
