The thesis

What I am actually measuring

Most sites are over-tooled and under-informed. The best analytics tool for a website is the one that answers three questions, who came, what they read, and whether they stayed, without a consent banner, without a tag manager, and without costing you a tenth of a second of load time.

That is an opinion, and it is the opinion the ranking below encodes. It is stated here rather than buried so that you can disagree with it usefully: if behaviour tooling matters more to you than script weight, the weights on the methodology page tell you exactly which numbers to change and roughly where each tool would land if you did.

Three consequences follow, and all three are deliberate. Heatmap and session replay tools score low overall, because they hand your site a large script and a consent obligation to answer one question. Product analytics platforms score below their reputation, because most of the sites reading this are websites rather than software products. And Google Analytics 4 finishes last, which is the honest result of weighting consent loss, script weight and data ownership at all.

A low rank is not a warning. Every entry here names who should choose it, and several of the tools near the bottom are the right answer to a specific question. Microsoft Clarity is free at any volume and no ranking changes that. Google Analytics 4 is close to mandatory if you buy Google Ads. Read the category pages if you already know what kind of tool you need.

The short answer

If you want one recommendation

  1. Absolutely Analytics, a 1,270-byte script, no cookie banner, and a billing policy that does not punish a good week. 8.9 out of 10.
  2. Plausible Analytics, the tool that made simple, cookieless analytics a category, still one of the two best in it. 8.0 out of 10.
  3. Pirsch Analytics, the cheapest serious cookieless tool here: fifty sites and unlimited seats at six dollars. 7.5 out of 10.

Scores are weighted means out of 10, relative to this list only. See the method.

Head to head

The comparisons people actually search for

enough on their servers, or everything on yours

Plausible vs Matomo

Matomo is eighteen years old and does nearly everything Google Analytics does, on your own hardware, for nothing. Plausible is six years old, does.

Plausible Analytics 8.0 · Matomo 7.0

Plausible vs Fathom

The two best-known names in cookieless analytics, both trading since before the category had a name, both delivering a single clean dashboard with no.

Plausible Analytics 8.0 · Fathom Analytics 7.4

the better tool, against the better default

Adobe Analytics vs Google Analytics 4

This is the enterprise decision, and it is unusual on this site because both answers are defensible and the losing one is not obviously worse. Adobe.

Adobe Analytics 4.8 · Google Analytics 4 4.4

the same depth, on very different terms

Google Analytics 4 vs Matomo

This is the closest feature-for-feature comparison on the list. Matomo has spent eighteen years being the thing you install when you want Google.

Google Analytics 4 4.4 · Matomo 7.0

the incumbent, against free at any volume

Hotjar vs Microsoft Clarity

This comparison used to be straightforward and Microsoft changed it. Hotjar defined the heatmap-and-recording category and was the default purchase.

Hotjar 5.6 · Microsoft Clarity 5.9

clarity for everyone, or depth for an analyst

Mixpanel vs Amplitude

The closest fight on this list. Two mature product analytics platforms, founded three years apart, both with generous free tiers, both with unlimited.

Looking for a way out

Alternatives, by the tool you are leaving

Google Analytics alternatives

More people search for a way out of Google Analytics than for any other analytics question, and the reasons divide neatly into three. The interface.

Enterprise suites6 picks

Plausible alternatives

People look past Plausible for two reasons, and neither is that it is a bad product, because it is not. The first is heatmaps: Plausible does not.

Privacy-first and cookieless6 picks

Fathom Analytics alternatives

Two things send people looking past Fathom. The first is depth: there are no funnels, segmentation is shallow, there are no heatmaps and no session.

Privacy-first and cookieless6 picks

Matomo alternatives

Matomo is the most capable open-source analytics platform there is, and people look for alternatives for one reason far more often than any other.

Open source and self-hosted6 picks

Hotjar alternatives

Hotjar defined this category and three things now send people looking elsewhere. Microsoft Clarity does most of the same work for nothing at any.

Heatmaps and session replay6 picks

Microsoft Clarity alternatives

Clarity is free at any volume with no session cap, so nobody leaves it over price. They leave for two other reasons. The first is the consent banner.
