Most web analytics comparisons skip the hard parts: what the free plan actually collects, what it withholds, and whether a free tool can replace a paid one for a real-world site. This guide cuts through that.
The tools below are compared for small websites, blogs, affiliate sites, and side projects. The focus is on what free gives you in practice — traffic volume, data retention, setup complexity, and privacy trade-offs.
Where to start
Google Analytics 4 remains the most capable free analytics tool for most websites, with deep traffic, acquisition, and conversion data — but it requires cookie consent in most regions and is not suitable for privacy-first deployments. Google Search Console is not general-purpose analytics, but it is the definitive free tool for understanding how your site performs in Google Search specifically; use it alongside analytics, not instead of it. Microsoft Clarity is the best free option for heatmaps and session recordings and pairs well with GA4 at no cost. Umami is the strongest self-hosted option for teams that want privacy-friendly analytics without paying for a third-party SaaS tool. Matomo On-Premise is more powerful but significantly more complex to run.
For a beginner setup, start with the question you need answered. Search visibility points to Search Console. Traffic sources and conversion events point to GA4. Layout confusion points to Clarity. Privacy-friendly dashboards point to Umami, and full self-hosted reporting depth points to Matomo if you can maintain it.
| Tool | Best for | Free plan includes | Main limitation |
|---|---|---|---|
| Google Analytics 4 | Full-featured traffic and conversion analytics | Unlimited pageviews, events, acquisition and behaviour reports | Requires cookie consent; limited raw data export on free tier |
| Google Search Console | Search traffic and keyword performance only | Query, impressions, clicks, CTR, Core Web Vitals — unlimited | Search data only; no direct-traffic, social, or referral data |
| Microsoft Clarity | Heatmaps and session recordings alongside GA4 | Unlimited heatmaps, session replays, rage-click and scroll data | No traffic acquisition data; not a standalone analytics tool |
| Umami (self-hosted) | Privacy-friendly analytics without a third-party SaaS dependency | Full open-source platform; all data stays on your server | Requires a server or hosting to run; ongoing maintenance overhead |
| Matomo On-Premise | GA4-equivalent depth with full data control | All core features when self-hosted; no data caps or seat limits | Significantly more complex setup and server requirements than Umami |
Why web analytics still matters in 2026
Organic search has become harder to read. Zero-click results, AI-generated answers, and increased SERP features mean raw traffic numbers tell less of the story than they used to. But web analytics is still the primary way to answer questions that matter for a small site: which pages are landing pages, where visitors drop off, which sources actually convert, and whether a publishing push led to a measurable change in behaviour.
The good news is that the free tier of major analytics platforms is genuinely capable. A small website can get years of useful data without paying anything — provided you choose the right tool for your use case and understand the trade-offs around data collection and compliance.
For most small sites, the practical stack is two or three tools rather than one. Search Console tells you what Google searchers saw before they clicked. GA4 or Umami tells you what happened after visitors arrived. Clarity explains page-level behavior when the numbers alone do not show why users are stuck. Keeping those jobs separate makes setup easier and avoids expecting one free tool to answer every analytics question, especially on a new site with limited traffic and few conversions during the early launch stage.
The best free web analytics tools in 2026
Google Analytics 4
GA4 is Google’s current analytics platform, and the free version has no pageview cap, no seat limit on reporting, and no hard data retention wall for standard reports. The standard data retention window for event data is set to two months by default but can be changed to fourteen months in the admin settings — do this immediately after setup if you want longer historical comparison.
GA4’s free value is breadth: unlimited traffic, acquisition, engagement, and conversion tracking; up to 500 distinct event types per property; Looker Studio integration; Search Console integration; and basic audience and funnel reports. It is the broadest free dashboard for understanding where visitors come from and what they do after they arrive.
The limits are complexity and compliance. Raw event-level export requires BigQuery, which is free within quota limits but adds setup work. Some advanced predictive audiences and modelled conversion features depend on higher data volumes, and there is no SLA or guaranteed support on the free tier. If you are in the EU or targeting EU visitors, cookie consent and consent mode need to be handled correctly.
GA4 fits any small-to-medium site that needs full-funnel traffic and conversion data and is comfortable managing the setup. No other free tool gives you the same acquisition, behaviour, and conversion reporting in one interface, but it is not the easiest or most privacy-light starting point.
Google Search Console
Search Console is not a general-purpose analytics tool — it does not track pageviews, sessions, referrals, or time on page. What it tracks is how Google sees and ranks your site, and that is valuable enough to treat as a required complement to any analytics setup.
Search Console is free search intelligence rather than whole-site analytics. It gives query-level clicks, impressions, CTR, and average position for up to 16 months; page-level search performance; index coverage; crawl error reporting; Core Web Vitals field data; and structured data or rich-result validation.
The restriction is scope. Data is aggregated, low-volume queries may be grouped as “other,” and there is no user-level or session-level view. It cannot explain direct, social, referral, or email traffic because it only covers Google Search.
Every website should use Search Console alongside GA4, Umami, or another analytics tool. It is the only free source for Google-reported impressions and CTR at the query level.
Microsoft Clarity
Clarity is a free behaviour analytics tool from Microsoft. It does not replace traffic analytics — it augments it by showing what users actually do on a page: where they click, how far they scroll, where they rage-click, and recordings of individual sessions.
Clarity gives behaviour data that traffic dashboards do not: heatmaps, session recordings, rage-click, dead-click, and excessive-scroll detection, basic funnel analysis, GA4 integration, and a dashboard with behavioural insights. Microsoft does not state a session or recording cap, and the product has remained free since launch.
The limitation is that Clarity does not report acquisition sources, pageview counts by channel, or traditional conversion data in the way GA4 does. It is a companion to analytics, not a replacement. Session recordings may also auto-expire over time.
Clarity fits sites that need to understand layout and UX performance without paying for Hotjar or FullStory. It pairs naturally with GA4 because you can move between session recordings and traffic data when diagnosing why a page underperforms.
Umami (self-hosted)
Umami is an open-source, privacy-focused analytics platform. It is cookieless by default, collects no personally identifiable information, and stores all data on your own server. The self-hosted version is free to run; there is also a paid Umami Cloud option for teams that do not want to manage infrastructure.
Umami’s self-hosted free value is simple privacy-friendly traffic reporting: unlimited websites, unlimited pageviews, event tracking, referral and source data, real-time visitor view, multi-user access, custom domains, and no external data sharing.
The cost is infrastructure. You need a server or hosting environment, and ongoing maintenance such as upgrades, backups, and uptime is your responsibility. Reporting depth is lighter than GA4, with no built-in funnel analysis or session recording.
Umami fits developers and technically confident site owners who prioritise privacy compliance and do not want to use Google’s infrastructure. Cookieless tracking may reduce consent-banner complexity depending on your legal context, and the interface is easier to read than GA4 for basic traffic patterns.
Matomo On-Premise
Matomo is the most feature-complete open-source analytics platform available. The self-hosted version (On-Premise) provides everything in the paid Matomo Cloud plan — including ecommerce tracking, goal conversions, custom reports, and full raw data access — at no licensing cost.
Matomo On-Premise is the heavyweight self-hosted option. The free self-hosted setup includes a full analytics suite comparable to GA4 depth, ecommerce and goal tracking, funnels, cohort analysis, a tag manager, heatmaps and session recordings through on-premise plugins, complete data ownership, and built-in GDPR tools.
The setup is meaningfully more complex than Umami. Matomo requires PHP, a MySQL or MariaDB database, and a capable server. Some premium plugins are technically free in the self-hosted version but listed as paid plugins that require separate download and licence handling for cloud users, so plugin terms should be read carefully. Maintenance overhead is higher than any cloud tool here.
Matomo fits teams that need GA4-equivalent depth plus full data sovereignty and have someone comfortable maintaining it. It is not the right starting point for a small site with no server administration experience; GA4 or Umami will be easier.

Decision guide — when is free analytics enough?
Free analytics is enough when:
- You run a blog, affiliate site, content site, or small business website with under a few million pageviews per month
- You need traffic source, page performance, and basic conversion data
- You are comfortable with GA4’s setup complexity and cookie consent management
- Or you want privacy-friendly analytics and have the technical ability to self-host Umami
When to consider a paid option:
- You need guaranteed data retention beyond what the free tier provides without configuration
- You need customer-level analytics or CRM-linked attribution (requires paid tools like Mixpanel or Amplitude)
- You run a SaaS product where you need event-stream analytics at scale (product analytics, not website analytics)
- You need formal SLA, dedicated support, or compliance certifications your legal team requires
Product analytics versus website analytics: Tools like Mixpanel, Amplitude, and PostHog target SaaS and app teams tracking feature usage within a logged-in product. They are a different category from the website analytics tools above. PostHog has a generous free tier for product analytics if that is your context.
The takeaway
For most small websites, the combination of Google Analytics 4 and Google Search Console covers everything you need to understand your traffic and improve it — and both are free with no meaningful cap for sites at this scale. Add Microsoft Clarity if you want heatmaps and session recordings without paying for Hotjar.
If cookie consent or privacy compliance is a significant concern for your audience, Umami self-hosted is the most practical starting point: it is lighter to run than Matomo, faster to set up, and genuinely free as long as you have hosting.
Matomo On-Premise is worth the effort if you need GA4-depth reporting without relying on Google infrastructure, and you have someone comfortable managing a PHP application long-term.
