does google need prerender?

NO! Do not use prerender for googlebot.

If you have angular app – do not use preredner for Google  – it will only slow down your crawl rate.

In my site.

  • By using prerender for google – request was send one by one, aprox 1 req per 2 sec (!)
  • When I disabled prerender for google (default setting) – few requests/sec,.
