Ask HN: Solutions to count website visitors that's not blocked by ad-blockers?

I'm trying to weed off from Google Analytics and looking for alternatives. I don't need anything complex, I'm mainly looking for a reasonable guesstimate on the number of visitors per page. This is hindered by common use of ad-blockers, which understandably block many analytics scripts. Do I have to build my own solution to this or is there an existing product for counting visitors that is not blocked by ad-blockers?
