Pixelfed is a free and open-source image sharing social network service. It is decentralized, therefore user data is not stored on a central server, unlike other platforms. The fediverse is a large network of platforms that all speak a common language. Imagine if you could reply to Instagram posts from Twitter, or interact with your favorite Medium blogs from Facebook – federated alternatives like Pixelfed, Mastodon and WriteFreely enable you to do these types of things. In this step by step guide I will show you how to install Pixelfed on your Synology NAS using Docker & Portainer.

💡Note: This guide works perfectly with the latest Pixelfed v0.12.3 release.
