Pixelfed

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. Pixelfed uses the ActivityPub protocol which allows users to interact with other social networks within the protocol, such as Mastodon, PeerTube, and Friendica. Using this protocol makes Pixelfed a part of the Fediverse. The network is made up of several independent sites that communicate with one another, which is roughly comparable to e-mail providers. The parties involved do not all have to be registered with the same provider, but can still communicate with each other. Thus, users are able to sign up on any server and follow others on the other instances. Much like Mastodon, Pixelfed implements chronological timelines without content manipulation algorithms. It also aims to be privacy-focused with no third party analytics or tracking.
