We discuss how to install Pixelfed on Ubuntu VPS! This article provides a guide for how to install Pixelfed on Ubuntu VPS. What is Pixelfed? PixelFed is a decentralized, open-source photo-sharing platform similar to Instagram but built on the Fediverse (federated social networks using the ActivityPub protocol). It allows users to host their own instances and interact with users across different servers, much like how Mastodon works for microblogging. For those desiring to switch from mainstream social media platforms for a more privacy-conscious scenario or desiring a personalized social media platform for their community, Pixelfed is a great solution. Key Features of PixelFed: Decentralized: No single company controls PixelFed. Multiple instances (servers) can operate independently but still communicate with each other. Privacy-Focused: Users have control over their data, with features like end-to-end encryption and no ads or tracking. Instagram-Like Interface: Features include photo posts, stories, albums, and filters. Federation: Users can follow and interact with accounts from other federated services like Mastodon, Pleroma, and PeerTube. Self-Hosting: Businesses or individuals can create and manage their own PixelFed instances. Why Use PixelFed? For Photographers & Artists: No algorithmic timeline—followers see posts in chronological order. For Privacy Advocates: No ads, tracking, or data harvesting. For Businesses & Creators: A unique platform to engage with audiences outside mainstream social media.
