A reverse-engineered, self-hosted replacement for the official Obsidian Sync and Publish servers, written in Go. It provides end-to-end encrypted note synchronization, file history, vault sharing, and basic markdown publishing via a companion Obsidian plugin.

Use cases

• self-host obsidian sync server
• sync obsidian notes across devices without subscription
• host my own obsidian vault sync with encryption
• share an obsidian vault between users
• publish obsidian markdown notes on my own server
• replace obsidian sync paid plan with self-hosted alternative

When to choose

• you want to avoid Obsidian Sync subscription fees and self-host your notes
• you need end-to-end encrypted sync across iOS, Android, Linux, macOS, and Windows
• you want control over storage limits, user accounts, and server location
• you need vault sharing or basic markdown publishing on your own infrastructure

When to avoid

• you use Obsidian 1.4.11 or newer, where the companion plugin is intentionally broken
• you want a zero-maintenance, officially supported sync solution
• you need full-featured publishing with rendering, themes, and graph search
• you are uncomfortable with a reverse-engineered protocol that the vendor actively opposes
