USKO Live is an independent fan project that brings together character and item information from Knight Online private servers. Players can select a server and search for a character to view details such as level, class, clan, equipment, and stats in one place. Character pages include a 3D model that can be rotated and zoomed, allowing visitors to inspect armor, weapons, wings, and cosmetic items.

Item details show defense, stat bonuses, resistances, and upgrade levels, while an item search helps users find which characters on a server have a particular item. The site also offers an AP calculator for building and comparing character setups. Users can choose a class and level, equip items, include buffs, and see totals for AP, AC, HP, MP, resistances, and stats; setups can be saved and shared by link.

Additional features include recently archived characters and lists of top-level characters and highly upgraded weapons and armor for each server. Information is compiled from publicly visible in-game data and refreshed regularly
