Update in May 2021: Browser Plugin and DevTools Overlay for Chrome
To activate the overlay, enter developer tools and open the command menu (using Control/Command + Shift + P ) and type “show render” to see the render options drawer, where you can check “core web vitals” to make the overlay appear immediately.
This is basically the same as Addy Osmani's Web Vitals extension, which has been a free extension for the Chrome web browser, previewing what is now built-in to chrome dev tools as the new Core Web Vitals overlay.
