NewsBlur is an open-source, full-stack RSS news reader and social reading platform with a hosted service and native clients. The backend crawls and parses feeds at scale, stores stories, and pushes updates to users in near real time, while the web app and mobile apps provide rich reading experiences. Its hallmark is “training”: you can tell the system what you like or dislike—authors, keywords, tags—and it prioritizes stories accordingly, surfacing what matters most. Features like saved stories, tagging, full-text search, and offline reading make it practical for heavy information consumers. Social elements allow sharing to your own “blurblog,” following friends, and discovering curated content, which turns a solitary reader into a lightweight network. Architecturally, it demonstrates a production-ready aggregation pipeline, a multi-tenant web app, and cross-platform clients living in one coherent codebase.
