Case Study: CodePen achieves personalized, scalable activity feeds with Stream Feeds

How Stream Activity Feeds Power CodePen’s Social Development Experience

CodePen, the social development community for front-end designers and developers, needed to overhaul its aging activity feed infrastructure to improve performance and add more personalized content discovery. The team wanted a more scalable way to support its Following, Trending, and Activity feeds while staying competitive in a fast-changing social media landscape, and turned to Stream and its Stream Feeds API for help.

Stream replaced CodePen’s slow, hard-to-maintain in-house feeds with a scalable, feature-rich solution that included personalized Following, Trending, and Notification feeds, plus AI-powered recommendations. As a result, CodePen gained a smoother, more modern discovery experience with customized trending content and “Interesting People to Follow” suggestions, helping boost engagement and deliver a social experience that rivals leading platforms.
