The Vercel Toolbar now helps you investigate your site's Interaction to Next Paint (INP).

This new Core Web Vital, which impacts Google search ranking as of March 2024, is now available in the toolbar menu under Interaction Timing. As you interact with your site, this tool measures input delay, processing times, and rendering delay and allows you to inspect in detail how these are affecting each interaction's latency.

This tool can also notify you as you navigate your site of any interactions that take more than 200ms, the upper limit for a good INP score. These toasts can be configured in Preferences under the toolbar menu.
