> - visitor counters

I've kept those alive at w3counter.com since 2004 (before Google acquired Urchin and turned it into Google Analytics). It's not exactly an in-demand feature so I don't think it's even mentioned on the homepage, but after signing up, you can choose from a couple dozen counter styles, or the standard invisible tracking tag. Been working on redoing that site to re-launch it as a cookieless, zero-personal-data tracker later this year.

Actually I still host https://www.websitegoodies.com/ which I originally made in 1999, and that has a simple hit counter service too. So there are some counters I've been hosting for over 20 years.
