Login and signup pages cause 100% CPU usage and heavy browser lag

Hi Netlify team,

I want to report a performance issue with the Netlify login and signup pages.

When I open the login page or signup page, my browser starts lagging heavily and my PC CPU usage jumps to 100%. The page becomes very slow to interact with, and sometimes the browser feels almost frozen.

This seems to happen specifically on the Netlify authentication pages. Other pages work normally until I open those pages.

My setup:

  • OS: Windows 11
  • Browser: Brave Browser
  • Device: Desktop PC

I tried reloading the page and opening it again later, but the issue still happens.

It feels like something on the frontend may be causing unusually high CPU usage, possibly an animation, script, or client-side process on the auth pages.

Can someone from Netlify check this?

Thanks.
