The best web analytics tools in 2026

Google Analytics 4 is the standard: free, complete, tied to Google Ads, Search Console and BigQuery. It tracks events (views, clicks, purchases), follows journeys across web and apps, and builds audiences for ads.

The downside: GA4 thinks in events and explorations, and finding a simple report takes some learning. Check the retention setting on day one: on the free version, user-level and event data used in explorations is kept for 2 or 14 months, and Large and XL properties are held to 2 months; standard reports are not affected. On privacy, France's CNIL excludes tools whose vendor reuses data for its own purposes from its consent exemption, so in Europe GA4 usually runs behind your consent banner. In the US, Google does not sign HIPAA business associate agreements for Google Analytics, which rules it out on pages that handle patient data.

For very large volumes, Google Analytics 360 is sold on quote.

Matomo (formerly Piwik) is a complete Google Analytics alternative. The self-hosted version is free, with unlimited users and hits: you install it on your server and your data goes nowhere. Matomo Cloud, hosted by the vendor in Europe, is priced on traffic, with a free trial.

Reports feel like the old Google Analytics, which many marketing teams like. Configured properly, it can run without consent where European regulators allow it.

The limit: self-hosting needs a server and someone to maintain it, and heatmaps and session recordings are paid plugins there. Matomo Cloud starts at $26 a month (excl. tax, billed monthly) for 50,000 hits, with 2 months free on annual billing, and that plan includes 1,500 heatmap pageviews and 150 session recordings a month. Matomo's own rule of thumb: 100 pageviews make about 110 to 120 hits, so a site at 45,000 pageviews sends 49,500 to 54,000 hits, at or past the 50,000-hit tier. Past your tier, each extra 5,000 hits costs $2.60 (excl. tax). Leaving Matomo later? See what to switch to from Matomo.

Mixpanel tracks user actions, not pageviews: signups, projects created, payments. Its funnels and retention reports take a few clicks to build. Our full Mixpanel review covers each plan.

The free plan includes unlimited seats, up to 1 million events a month and 10K session replays. Growth starts at $0 for the first million events, then jumps: 1.5 million events a month cost $100 a month billed yearly ($140 month to month), and 10 million cost $840 a month billed yearly. Startups under 5 years old with up to $8M raised, that haven't redeemed another offer, get their first year free.

The limit: for marketing acquisition (sources, campaigns), GA4 goes further. Its closest rival is Amplitude: our Amplitude vs Mixpanel comparison splits the two, and our product analytics ranking goes wider.

Plausible fits on one page: visitors, sources, pages, countries, goals. No cookies, a script Plausible puts at 54 times smaller than Google Analytics, data hosted in the European Union. The code is open: you can also self-host it for free (Community Edition).

Starter is $9 a month for up to 10k pageviews on one site, or $90 a year (2 months free), with a 30-day trial and no card. Growth ($14 a month) and Business ($19 a month) add saved, then shared, segments and annotations at the same traffic. The price rises with traffic.

The limit: no deep product analytics, few segments. By design.

PostHog bundles product analytics, web analytics, session replay, feature flags and experiments. Every month, 1 million events, 5K recordings and 1 million flag requests are free; beyond that each product is usage-based, with no annual contract.

PostHog says 97% of companies use it for free, and without a card on file usage simply stops at the free limits. Past the free million, watch which events you identify: an anonymous event costs $0.00005 and an identified one $0.000198, so a million extra identified events cost $198 against $50 anonymous. For a startup, it is often the fastest way to get everything in one place.

The limit: it is built for technical teams and harder for marketers to pick up.

Fathom is close to Plausible: a simple, cookieless, privacy-first dashboard. Every plan has the same features and includes 50 sites; the price follows traffic: $15 a month up to 100,000 pageviews, $25 up to 200,000, $60 up to a million.

There is a 7-day trial (card required), and 2 months free on yearly billing. Two details change the bill: pageviews and custom events share the same allowance across all your sites, and sites beyond the first 50 come in packs of 50 for $10 a month.

The limit: like Plausible, no product analytics.

Microsoft Clarity is not a full analytics suite: it shows behavior. Heatmaps show where visitors click, scroll and drop off, and session recordings replay real visits so you can see where people get stuck. Microsoft sells it as free forever, with no limits on traffic.

That makes it a natural partner for Google Analytics 4: GA4 tells you how many people convert, Clarity shows why the others did not. It does not replace a traffic and conversion tool, and recording sessions means your cookie and privacy notice must cover it. In the European Economic Area, the UK and Switzerland, Microsoft requires explicit consent before Clarity sets cookies; without it, funnels and session recordings can be affected.

Adobe Analytics is the tool of very large sites: fine-grained segmentation, real-time analysis, links with other Adobe tools.

Pricing is set on quote with Adobe.

The limit: a demanding tool that needs a trained team and a real budget; oversized for an SMB.
