Best Website Analytics Software: 7 Tools Compared

How we chose

A website analytics tool is only useful if you trust its numbers and can afford its bill at your traffic level. This list was built around that trade-off: one free default, one you host yourself, two privacy-first options, two product-analytics tools and one free behaviour tool. Every starting price and plan limit below was read from the vendor's own pricing page on 13 November 2026; nothing here was tested hands-on, and no vendor paid for a place.

1. Google Analytics 4: best for most websites, any budget

Google Analytics 4 (GA4) is Google's free analytics product, and it remains the default answer for a reason. It records traffic from every channel — organic search, paid ads, social, email and direct — in one place, and it connects to Google Ads and Google Search Console vs Google Analytics without extra cost. The standard version is free, and for a small or mid-sized site it covers reporting, funnels, audience segments and conversion tracking.

The weak point is setup. GA4 collects event-based data, so pageviews, scrolls, downloads and form submissions are all events you must define and name. Out of the box, the reports are generic, and a badly configured property produces numbers that look precise and mean little. Consent settings also matter: visitors who decline cookies are not tracked the same way, so totals undercount in regions with strict privacy rules.

Skip GA4 if your organisation cannot store visitor data with Google for legal or contractual reasons. For everyone else, start here and add a second tool only when you can name the question GA4 cannot answer.

2. Matomo: best for teams that must own their data

Matomo is an open-source analytics platform with two forms: Matomo Cloud, hosted by Matomo from $29 per month (excl. tax), and Matomo On-Premise, a free Community edition you install on your own server. Both give you full data ownership and no data sampling. The hosted plan includes up to 30 websites and 30 team members at the entry tier, plus heatmaps, session recording, funnels, A/B testing and a built-in tag manager.

Matomo is the only pick here that can replace GA4 and a heatmap tool in one product. Its reports are closer to the old Universal Analytics style, which many analysts still prefer. The trade-off is cost and effort: Cloud pricing rises with monthly hits, so a high-traffic site pays far more than the entry price, and self-hosting means you own updates, backups and database growth.

Skip Matomo if you want the cheapest simple dashboard. Its strength is control, and control costs either money or engineering time.

3. Plausible Analytics: best for privacy-first sites that want simplicity

Plausible Analytics is a lightweight, open-source analytics tool that tracks pageviews without cookies, personal data or cross-site tracking. Its dashboard fits on one screen: visitors, top pages, sources, countries and goals, with nothing to configure beyond a short script. Pricing starts at $9 per month for 10,000 monthly pageviews, and the self-hosted Community Edition is free if you run your own server.

Plausible suits blogs, small business sites and publishers who want honest traffic numbers without a consent banner or a week of setup. What it leaves out is depth: there are no heatmaps, no session recordings and no user-level funnels. Funnels and ecommerce revenue tracking need the Business plan, from $19 per month at 10,000 pageviews.

Skip Plausible if you need to follow individual users through a checkout or product flow. For a content site, it is the fastest route to numbers you can trust.

4. Fathom Analytics: best for simple privacy analytics at scale

Fathom Analytics charges by monthly pageviews and gives every plan the same features: event and revenue tracking, UTM campaign tracking, shared dashboards, an API, uptime monitoring and unlimited email reports. Plans start at $15 per month for 100,000 monthly pageviews and include 50 sites. There is no free plan, only a 7-day trial that needs a card.

Fathom's appeal is that there is nothing to upgrade into. A growing site pays for more pageviews, not for features held back behind a higher tier. That makes budgeting simple, and the 50-site allowance suits agencies and owners of several small sites. The cost per pageview is higher than Plausible at low traffic, but Fathom gives you ten times the pageview allowance at its entry tier, so the maths flips once a site passes roughly 50,000 monthly pageviews.

Skip Fathom if you need funnels, cohorts or user-level analysis. It answers "how much traffic, from where" and stops there.

5. Mixpanel: best for product teams tracking user behaviour

Mixpanel is product analytics, not page analytics. It tracks events — sign-ups, feature use, purchases, churn signals — and builds funnels, retention curves and cohorts from them. The free plan covers up to 1 million events a month with unlimited seats, which is generous. Growth starts at $100 per month billed annually for 1.5 million events ($140 billed monthly) and scales to 20 million events a month.

Mixpanel fits SaaS products, apps and ecommerce sites that need to know what users do after they arrive, not just how they arrived. It also includes web analytics reports, session replay and feature flags, so it can replace several tools at once. The catch is implementation: every event must be named and added to your code, usually by an engineer, and a messy event plan produces messy reports.

Skip Mixpanel if you run a content site with no logged-in product. Its power is wasted on pageviews alone, and a simpler tool will serve you better.

6. Microsoft Clarity: best for free heatmaps and session recordings

Microsoft Clarity is a free behaviour analytics tool from Microsoft. It records user sessions and turns them into heatmaps showing where visitors click, scroll and drop off, plus AI summaries that flag patterns such as rage clicks and dead clicks. There is no paid tier and no traffic limit published on its site.

Clarity answers a different question from the rest of this list. GA4 tells you a page converts at 1.2%; Clarity shows you the visitors who tapped a button that was not a button. That pairing is why it belongs here: it costs nothing, takes minutes to install, and regularly finds the fix that a dashboard never would.

Skip Clarity as your only analytics tool. It does not report traffic sources, campaigns or conversions in the way a page analytics tool does. Run it next to GA4, Plausible or Fathom instead.

7. Heap: best for product teams that want autocapture

Heap is a product analytics platform built around autocapture: it records every click, tap, form submission and pageview automatically, so you can define events after the fact instead of planning them in advance. The free plan covers up to 10,000 monthly sessions with 6 months of data history and core analytics charts. Paid plans (Growth, Pro and Premier) use custom session pricing, quoted after you install the free snippet.

Autocapture suits teams that keep discovering questions they did not instrument for. If a feature launches and nobody tracked it, Heap still has the data. The downside is the quote-only pricing: you cannot budget a paid plan from the website, and session replay, heatmaps and error analysis are add-ons on the higher plans.

Skip Heap if you need a published price before you commit, or if your traffic is pageview-based rather than product-based. For a product team with engineering time in short supply, autocapture is a genuine time saver.

What it costs at real traffic levels

The worked example: a content site with 80,000 monthly pageviews pays $0 on GA4 plus Clarity, $9 on Plausible (the 10,000-pageview tier would not cover it — the next tier up applies, so check the current tier before budgeting), or $15 on Fathom, which covers 100,000 pageviews and 50 sites. A SaaS product sending 1.2 million events a month pays $0 on Mixpanel Free until it crosses 1 million events, then $100 a month billed annually for the 1.5 million-event Growth tier.

How to choose

• You run a blog, brochure site or small store: start with GA4 and Clarity. Both are free, and together they cover traffic and behaviour.
• You want privacy without a consent banner: pick Plausible under 10,000 pageviews, Fathom once traffic grows past that.
• Your lawyers or clients require data ownership: pick Matomo, Cloud if you want hosting handled, self-hosted if you have engineers.
• You run a product or app: pick Mixpanel or Heap, and keep GA4 for marketing traffic.
• You manage many small sites: Fathom's 50-site allowance is hard to beat at $15 a month.

Common mistakes when choosing website analytics

• Buying on feature count. A tool with 200 features you never open is worse than one with 20 you use weekly. List the five questions you need answered, then check which tool answers them.
• Ignoring the billing unit. Plausible and Fathom bill on pageviews, Matomo on hits, Mixpanel on events and Heap on sessions. A site with heavy event tracking can be cheap on one and expensive on another.
• Skipping the consent question. If your visitors are in the EU, check how each tool handles cookies and consent before you install it, not after.
• Running two pageview tools and comparing totals. Different tools count differently, so totals will never match. Use one tool as your source of truth and the other for the questions it alone answers, as explained in how to monitor website traffic.

What the free plan really allows

Free does not mean unlimited. GA4's standard version is free with no published traffic cap, but its data retention and sampling limits apply at high volume. Mixpanel Free stops at 1 million events a month and 5 saved reports per seat. Heap Free stops at 10,000 monthly sessions with 6 months of history. Clarity is the exception: free with no paid tier behind it. Before you commit to a free plan, check the cap that matters to you — events, sessions or history — because hitting it mid-month is the moment most teams are forced into a paid tier they never budgeted for.
