What is sloth?
Sloth is a Chrome extension that slows down page loading by throttling network speed and CPU performance. It helps developers simulate real-world user conditions with slow devices and connections to identify performance issues before deployment.
Frontend developers and performance engineers who need to test web applications under realistic slow network and device conditions.
Developers choose Sloth because it provides one-click throttling across all same-origin URLs, making performance testing faster and more convenient than manual Chrome DevTools configuration.
