About This Tool

The Website Feature Load Estimator helps developers and site owners understand the "weight" of third-party tools. It uses industry-standard performance metrics to estimate how much a feature (like a Live Chat or Video) might slow down your Largest Contentful Paint (LCP) and increase Total Blocking Time (TBT).
