The INP metric measures how quickly your website responds to user input. For example, when a visitor clicks a button INP tells you how soon after the interaction the page updated visually.
Most lab tools like PageSpeed Insights don't simulate interactions with the page. Our INP checker automatically interacts with page elements and reports the interaction delay in milliseconds.

The Core Web Vitals are a set of three user experience metrics that Google uses as a ranking signal.
Google is replacing the old First Input Delay (FID) with Interaction to Next Paint in March 2024.
Our INP tester reports both real user data from Google and INP data from our custom lab test.
DebugBear real user monitoring (RUM) can report INP issues across your whole website and helps you identify what pages to optimize first.
DebugBear RUM tells you what page elements were most commonly interacted with and how long each interaction took.
DebugBear not only provides its own monitoring but also keeps track of Google data that impacts rankings.
