How to Install Vaultwarden on Your Synology NAS

Vaultwarden is an unofficial Bitwarden server implementation written in Rust. Vaultwarden is compatible with the official Bitwarden clients, and is ideal for self-hosted deployments where running the official resource-heavy service is undesirable. In this step by step guide I will show you how to install Vaultwarden on your Synology NAS using Docker. If you are a more proficient user, I recommend the following installation for Vaultwarden: Install Vaultwarden With Portainer. Note: If you want to Install the official Bitwarden, check out my new article on How to Install Bitwarden on Your Synology NAS.

💡Note: This guide works perfectly with the latest version of Vaultwarden 1.30.5
