Leaving Google Analytics (GA4)? Here’s an honest, up-to-date comparison of the leading open-source and privacy-friendly alternatives — what each is good at, whether you can self-host it, and what it costs. Including PVUV.ai, the only one built to tell real traffic from bots and protect your ad revenue.
Short answer: for a privacy-friendly, lightweight GA replacement, Plausible and Umami are great; for GA-level depth, Matomo. If your site runs on ad revenue and you need to catch invalid traffic and bots — something none of the others do — PVUV.ai is the one to look at, and it’s free (hosted or self-hosted).
Every tool here measures traffic. They differ on privacy, how much you self-host, and — crucially — whether they do anything about fake traffic.

Only PVUV.ai combines invalid-traffic detection and ad protection with a serverless, self-hostable, open-source core — while staying free to run.
Honest one-liners on where each tool fits.
Open-source, self-hosted or free hosted, running on Cloudflare Workers + D1. The only option here that scores every visit for authenticity, flags invalid traffic and bots, and can gate your ads. Best if you monetise with ads or care about traffic quality.
Open-source, privacy-first and very light (<1 KB script). Lovely simple dashboards. Cloud is paid; self-hosting needs your own server + Postgres. No bot/ad-fraud features.
The closest to GA in depth — heatmaps, funnels, goals, session recordings. Open-source and self-hostable, but heavier (PHP + MySQL) and needs maintenance. Cloud tier is paid.
Open-source, tiny and privacy-friendly, with clean dashboards. Self-host on your own server + database. Great for simple sites; no invalid-traffic or ad features.
Privacy-first and dead simple, but closed-source and cloud-only (paid) — you can’t self-host it. A good hands-off option if open-source isn’t a requirement.
Free, privacy-first and zero-setup if you’re already on Cloudflare — but basic (no custom events). Fine as a lightweight pageview counter, not a full analytics stack.
GA4 is free and powerful, but it comes with trade-offs that push many site owners to look for an alternative:
If traffic quality and ad revenue matter to you, that last point is usually the deciding one — and it’s the reason PVUV.ai exists.
It depends on your goal. For a lightweight, privacy-first replacement, Plausible or Umami; for GA-level depth, Matomo. If you need to detect invalid traffic and protect ad revenue, PVUV.ai is the only open-source option here that does it — and it’s free to self-host or use hosted.
PVUV.ai, Plausible, Matomo and Umami are all self-hostable. PVUV.ai is the lightest to run — it works on Cloudflare Workers + D1 with no separate database or server to maintain. Fathom and GA4 are cloud-only.
Yes. Umami and PVUV.ai are free to self-host, and PVUV.ai also has a free hosted version. Plausible and Matomo are free to self-host but charge for their managed cloud; Fathom is paid only.
All of them do web analytics. PVUV.ai adds a layer none of the others have: it scores every visit for authenticity, detects invalid traffic and bots that only show up in aggregate, and can load ad code only for traffic it trusts — while running serverless on your own Cloudflare account.
PVUV.ai is a free, open-source Google Analytics alternative with built-in invalid-traffic detection — use the hosted version or self-host it on your own Cloudflare account.
