OakData vs Fathom
Fathom keeps it simple. OakData keeps the whole story.
Fathom is clean, private, aggregate website stats. OakData is what you graduate to when the questions get harder than "how many visitors?"
Fathom Analytics helped define simple, privacy-focused web stats: a lightweight script, a single elegant dashboard, cookie-free measurement, and EU data isolation for GDPR peace of mind. For a content site or portfolio that needs clean traffic numbers, it's a genuinely pleasant product.
The ceiling arrives when you need to act on the numbers. Fathom can tell you conversions dipped. It can't show you the sessions of the people who dropped, the element they rage-clicked, or the revenue each acquisition channel actually produced. OakData covers that entire layer, from replay to Stripe revenue, with the same single snippet.

Choose OakData if…
- You've outgrown counts and need to see sessions, journeys, and the people behind conversions.
- You want product-grade tooling like replay, funnels, heatmaps, and error monitoring without assembling a stack.
- Revenue questions matter. OakData ties Stripe MRR and lifetime value to real people and channels.
Choose Fathom if…
- You want simple aggregate stats with a strict minimal-collection privacy posture.
- EU data isolation is a specific compliance requirement for you.
- Your site is content-only and per-visitor depth would be unused weight.
Questions
The person-level layer: visitor profiles with identity stitching, session replay, heatmaps, multi-step funnels you can drill into, error monitoring, Core Web Vitals, and Stripe revenue analytics. Fathom intentionally stays at aggregate stats.
No, it's a one script tag swap. Autocapture starts recording pageviews, clicks, forms, and sessions immediately, so most of what you had in Fathom (and the layers it lacked) works from day one.
Yes. OakData identifies visitors through first-party signals and a hardware-derived fingerprint. No cookies, no local storage required.
Honestly? Fathom, if all you'll ever look at is traffic counts. OakData earns its keep when you have a product, signups, or revenue: anything where knowing who and why beats knowing how many.
