Epic Games has launched the Fortnite Data API, making additional engagement and retention metrics for games like Fortnite Battle Royale available to third-party UEFN creators and companies.
The API provides access to data on individual island performance, including:
- Minutes Played: Total minutes played by all players
- Minutes per Player: Average total minutes per unique player
- Plays: Number of game sessions played
- Favourites: Number of times players favourited the island
- Recommends: Number of times players recommended the island (previously “Likes”)
- Peak CCU: Peak concurrent player count
- Unique Players: Number of distinct players
- Retention D1: Day-over-day retention
- Retention D7: Week-over-week retention
At present the only data available is for Epic-made experiences (that’s games like Fortnite Battle Royale, Fortnite Festival and LEGO Fortnite) but it will expand on June 9, 2025 to include all creator-made islands as well.
Epic says the hope is that making the ecosystem more open will help developers to “make data-driven decisions” as they “build, launch, and grow” their games, and has also confirmed that third-party platforms can also freely use the Fortnite Data API to develop their own visualizations and analytical insight tools for the game/platform as well.
