How we measure things.

Every metric on this site comes from public Fortnite UEFN platform endpoints. We poll on a fixed schedule, store the raw response, and derive aggregate metrics from there. We do not estimate, model, or fill missing data points — if upstream is silent on a given day, our chart shows a gap.

The pipeline runs once daily at 02:00 UTC. That's a deliberate trade-off: faster cadence means more API pressure on the source platform; slower cadence means stale data. Daily is the sweet spot for the vast majority of decisions creators and brand teams make against this data.

Higher-frequency refresh is on the roadmap for paid tiers (Starter gets hourly where the upstream supports it; Full gets the same with better rate-limit headroom).

Peak CCU

The highest concurrent-user count observed during the metric window. This is a snapshot maximum, not an average. A map with 10 minutes at 5,000 CCU and 23 hours at 50 CCU shows 5,000.

Plays

Total session starts in the metric window. Includes returning players. Does not deduplicate by user.

Favorites

Cumulative count of unique players who have favorited the map on the platform. This is a lifetime number, not a window number.

• We don't currently track Roblox. Cross-platform support is on the post-launch roadmap.
• Per-session retention curves are inferred from aggregate metrics; we don't have access to per-player session logs.
• If a creator deletes a map, historical metrics persist in our store but the map disappears from public listings.
• Daily metrics for a given map only begin once we first observe it. Maps published before our pipeline started lack early-history data.
