Help me view who is visiting a website

Hello,

I wanted to see if it is possible for someone on here to help me see who is visiting a competitors website. Is there a way to view the source so that I can contact them myself.

Please let me know if there's a better place to post this or if you know someone who can help me thanks!

Don't think so, you could try https://www.similarweb.com/
But I don't know how good it is

You can get a estimate of their monthly traffic but you can't see who is actually visiting them
