Social Feed Ranking Algorithm Simulator

Interactive 2D simulator of a mobile app's feed-ranking algorithm: tune recency, engagement and affinity weight sliders and watch the weighted score reorder a live feed, compared side by side against pure chronological order.

An interactive 2D simulator of a mobile app's feed-ranking pipeline: every post carries three real signals — recency (exponential time-decay), engagement (a saturating function of likes and comments) and affinity (relationship strength) — combined into one weighted score. Drag the weight sliders and watch the left-hand feed live-reorder, while the right-hand column holds the same posts in plain chronological order so you can see exactly which posts the algorithm promotes or demotes.

⚙ Under the hood

Adjust weights for recency, engagement, and affinity to see how they affect post ranking in a social feed.
