FortniteDB is an unofficial database and companion resource for Fortnite: Save the World. Created for players seeking detailed information and practical tools, the site brings together mission updates, game statistics, guides, leaderboards, and reference material in one place. Users can explore missions across Stonewood, Plankerton, Canny Valley, Twine Peaks, and Ventures, including alerts, rewards, and V-Bucks mission history. A mission finder and filters help players browse by zone, rarity, and reward.

The database covers schematics, ranged and melee weapons, traps, heroes, hero perks and abilities, survivors, and defenders. Players can also look up builds, quest lines, collection book rewards, commander rewards, and Venture rewards. Additional resources include an MSK guide, power-level and activity tools, and leaderboards. FortniteDB provides a Save the World store overview, support and help-ticket links, a Discord community, and an API. The site also features a creator-code promotion and states that it is not affiliated with Epic Games. Its purpose is to help players find current game information and organize their progression.
