What is INP by Chrome version
INP by Chrome version shows the Interaction to Next Paint (INP) segmented by the version of Google Chrome used by real visitors. This lens helps you detect interaction performance regressions tied to specific browser updates — something that can be easy to miss until it's too late.
Only Chrome versions that generated traffic to your site during the selected period will appear. Both desktop and mobile Chrome users are included.
Why this matters: Chrome updates sometimes introduce changes to input event handling, rendering priorities, or thread scheduling — all of which can affect INP, even if your site code hasn’t changed.
Healthy INP by Chrome version sample
Should you worry
If all major Chrome versions show INP in the green zone, you’re in great shape. Minor differences between versions are normal due to subtle rendering or scheduling variations. The key is consistency — no unexpected spikes in delay across widely-used versions.
Unhealthy INP by Chrome version sample
If the newest Chrome version suddenly shows worse INP:
It could be due to changes in input prioritization or main thread scheduling.
A new feature or animation might conflict with Chrome’s rendering behavior.
Your own frontend update might behave poorly on that specific version.
A third-party script may be triggering interaction delays in certain builds.
Likewise, if older Chrome versions show bad INP and still receive meaningful traffic, check for lack of support for newer APIs like requestIdleCallback, long animation frames, or inefficient polyfills.
Resolving unhealthy INP by Chrome version
Go-to action plan to resolve an unhealthy INP by Chrome version:
Ask Uxi to analyze your INP by Chrome version values and suggest improvements.
Filter by version and use other lenses to locate which page areas cause slow interaction.
Simulate INP of the suspected lens to see if fixing it will resolve the INP by Chrome version. If yes, this is where the resolution focus should be.
Use an automated INP optimization tool like INProve to improve your INP by Chrome version values.
Once you’ve improved INP, set an alert to be the first to know if it starts worsening again.
