If you run a small site and you've decided Google Analytics 4 is more reporting overhead than your traffic deserves, the shortlist of cookieless alternatives gets narrow fast. Two names keep surfacing: Fathom and Plausible. Both drop a sub-2KB script on your page, both skip cookies entirely so you can drop the consent banner, and both bill a flat monthly fee instead of harvesting your visitors. The interesting question isn't whether either one works — they both do — it's which trade-offs you're signing up for when you pick one.
We set up both on a low-traffic personal site, pointed real traffic at them for a couple of weeks, and compared the numbers and the day-to-day feel. Here's what actually separates them.
What "privacy-first" actually buys you
The shared baseline matters before the differences do. Neither tool sets cookies, neither stores IP addresses, and neither builds a cross-site profile of a visitor. In practical terms that's what lets you skip the cookie consent banner under GDPR, PECR, and CCPA — there's no personal data being processed, so there's nothing to consent to. That alone is the reason most indie builders switch: the banner is a conversion tax, and removing it is a real, measurable win.
Both also host visitor data in the EU. Plausible runs on infrastructure in Germany; Fathom routes EU visitor data through EU-isolated infrastructure as well. If your concern is keeping data out of US-controlled servers, either one clears that bar.
The scripts are tiny in both cases — a fraction of the weight of the GA4 tag, which routinely pushes 40KB+ before it loads its dependencies. On a site where you're fighting for a good Lighthouse score, swapping GA4 for either of these is one of the cheapest performance wins available.
Neither tool gives you the granular, session-level, cross-domain user journeys that GA4 does. That's the deliberate cost of being cookieless. If your business depends on stitching one visitor across multiple sessions and devices, you want a different category of tool — not Fathom, not Plausible.
Where Fathom and Plausible diverge
The single biggest fork is licensing. Plausible is open source under AGPL, and you can self-host the whole thing for the cost of a small VPS. That's a genuine escape hatch: if the hosted pricing ever stops making sense, your data and your setup move with you. Fathom is proprietary. You get a polished hosted product, but there's no self-host path and no source to fork.
The second fork is how the pricing tiers are shaped. Plausible's entry plan starts around \$9/month (billed annually) for roughly 10,000 monthly pageviews. Fathom's entry plan sits around \$15/month and starts you at 100,000 pageviews. So for a brand-new site with almost no traffic, Plausible is cheaper to start; for a site that already pulls tens of thousands of views, Fathom often gives you more headroom per dollar at the bottom rung.
Feature-for-feature on the dashboard, they're closer than the marketing suggests. Both give you top pages, referrers, countries, devices, UTM breakdowns, and custom goal/event tracking. Both let you proxy the script through your own domain to dodge ad blockers, which meaningfully closes the undercount gap that all client-side analytics suffer from. Both send clean email summaries and offer public dashboards you can share.
The texture differences are small but real. Plausible's filtering and segmentation felt slightly faster to slice during testing, and the self-host story is a category Fathom simply doesn't compete in. Fathom's onboarding is marginally more hand-held, and its pageview allotments scale in a way that suits a site already past the hobby stage. Neither difference is large enough to override the licensing and pricing decision above.
Which one fits your site
Pick Plausible if open source matters to you, if you might want to self-host later, or if you're starting from near-zero traffic and want the cheapest hosted entry point. The AGPL license is the deciding factor for a lot of developers — it's an insurance policy against pricing changes you don't control.
Pick Fathom if you'd rather not think about licensing at all, you want a hosted product with generous pageview tiers from the first paid plan, and your site already has enough traffic that the 100,000-pageview entry tier is useful rather than wasted.
For most indie builders the honest answer is that you won't regret either. The decision that actually moves your numbers is leaving GA4 behind — both of these remove the consent banner, both shave page weight, and both stop turning your visitors into someone else's data product.
Pricing and pageview tiers for both tools have moved more than once. Treat the figures here as a snapshot from mid-2026 and check each vendor's current pricing page before you commit to an annual plan — the entry thresholds in particular tend to shift.
If you're still standing up the site itself, the analytics choice is downstream of the platform. A no-code builder gets you to a publishable, fast page where either script is a one-line paste in the head — no build pipeline required.
