Metrivo vs Fathom Analytics
Fathom helped invent privacy-first analytics, and it's still one of the best at it: a ~2KB cookieless script, data kept forever, up to 50 sites on every plan, and a complete engine rebuild (V4) shipped in early 2026. Metrivo isn't trying to build a better Fathom. We built the layer Fathom deliberately doesn't: payment-provider ingestion, session-to-payment attribution, AI-search revenue, funnels, and a leak detector that tells you what to fix first. Here's the honest comparison, including where Fathom wins.

What Fathom genuinely does better
Forever data retention. Every Fathom plan keeps your data with no expiry. Metrivo retains 1, 2, or 5 years depending on plan. If a permanent traffic archive matters to you, Fathom is the clear winner here.
Many sites, one price. Up to 50 sites are included in every Fathom tier. Builders running a portfolio of small sites get enormous value from that.
Lightness and polish.Fathom's ~2KB script is lighter than ours, and the 2026 V4 rebuild added entry/exit pages, accurate time-on-page via departure pings, regex filters, and a Google Search Console integration. It is a mature, actively developed product.
What Fathom doesn't try to do
No funnels, by design.Fathom's model is single-step events and conversions. You can see that 40 people hit your "signed up" event, but not where the other 960 dropped out between landing, pricing, and checkout. Metrivo's funnels carry revenue at each step, and the Revenue Leak Detector ranks the drop-offs by what they cost.
Revenue is self-reported, not ingested.Fathom events can carry a value with per-event currencies — but your code assigns it at conversion time, and that's the end of the story. Renewals, failed payments, and refunds at Stripe never reach Fathom. Metrivo's revenue comes from your payment provider's webhooks (Stripe, Razorpay, Dodo, or the Manual Payment API), so the numbers reconcile and recurring revenue stays attributed.
AI traffic isn't a concept. As of June 2026, Fathom has no AI channel or labeling — notable now that Plausible and even GA4 have shipped one. AI visits show up as ordinary referrers, or vanish into Direct when the referrer is stripped. Metrivo detects 11 named AI sources with per-session evidence, honest confidence labels, and — uniquely — a connection to payments, so you see revenue per AI source rather than a referrer row.
Or run both
Keep Fathom as the permanent traffic record and add Metrivo as the revenue layer. Both trackers are async and cookieless, so they coexist cleanly. Read more on revenue attribution and AI-search attribution.
