Courier is a simple, secure, self-hosted, open-source sync solution for Obsidian.
Why Courier
Section titled “Why Courier”Real-time sync. Save on one device and the others see the latest content almost immediately.
End-to-end encryption. Notes are encrypted before they leave your device and only you can decrypt them; the server only ever holds ciphertext.
Open source and free. The whole sync solution — the server, the Obsidian plugin and the command-line tool — is open source and free.
Fast. It syncs quickly whether you have a large number of notes or very large files.
Easy to maintain. The optional desktop app handles deployment, upgrades, backups and keys, so you do not have to look after the server day to day.
