OpenCloud is a modern, open-source, self-hosted platform for file management, secure sharing, and team collaboration. It prioritizes simplicity and data sovereignty, giving users full control without unnecessary complexity. In this step by step guide I will show you how to install OpenCloud on your Synology NAS using Docker and Portainer.
This guide works perfectly with the latest OpenCloud v5.0.2Ā release.
