Like it or not, a huge part of modern web development involves the use of third-party providers: fonts, analytics, ads, tracking, and more all have an impact of performance, and can leave us (or, more worryingly, our visitors) susceptible to performance degradation.
In this talk, we'll take a look at unruly or uninvited (third-)party guests: how to detect them, how to audit them, and how to manage them. We'll also look at the different tools available to help us stress-test and quantify the overhead these third parties bring, and what that means for users and businesses alike.
