I develop this website, a guardian in Destiny 2 who is also a Computer Science student. I am lazy, so I created Xur Bot to manage this website for me and every guardian in this galaxy who wants to know where Xur is every weekend.
Xur Bot is linked to Bungie’s API, automatically generating and updating all the content you see on this website. When Xur arrives, Xur Bot immediately updates this website with Xur’s location and inventory. He also keeps this website’s list of all possible exotics Xur can sell up to date and was the first to report that Xur could sell exotics from Season Of the Drifter.
Xur Bot also manages a Twitter account that automatically tweets Xur’s location and inventory every time Xur arrives. @XurDestiny2
