With nearly 7,000 GitHub stars and instances spanning hundreds of federated servers, Pixelfed has become the leading open-source alternative to Instagram — delivering ad-free, algorithm-free photo sharing across the Fediverse. Built on Laravel with a Vue.js frontend, Pixelfed provides a polished, mobile-responsive interface where users upload photos and videos, apply built-in filters, create multi-image posts with alt text, share ephemeral stories, organize content into curated collections, and exchange direct messages — all without tracking, algorithmic manipulation, or targeted advertising. Federation through the ActivityPub protocol means Mastodon, Pleroma, and other Fediverse users can follow Pixelfed accounts, view photo posts in their timelines, and interact through likes, boosts, and replies, while Pixelfed users can discover content through both local and federated timelines. Instance administrators control registration policies, content moderation rules, federation blocklists and allowlists, storage backends including local or S3-compatible options, and server-wide settings. The Mastodon-compatible API enables third-party mobile app support alongside the built-in Progressive Web App experience. Advanced features include blurhash image placeholders for smooth loading, federated groups for community building through FEP-400e and FEP-1b12 extensions, HTTP Signatures with Authorized Fetch for secure federation, and comprehensive data export for full portability. Deployment requires PHP 8.1+, MySQL or PostgreSQL, Redis, and a reverse proxy, with Docker Compose configurations available for streamlined setup. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.
