mrkr vs Fathom.
Both are cookieless by default, so neither needs a banner as installed. Fathom counts pageviews on unlimited sites at a flat price. mrkr goes further into what those visits did and what they were worth.
In short
What is the difference between mrkr and Fathom Analytics?
Fathom is cookieless pageview analytics at a flat price, with unlimited sites and data retention that never expires. mrkr is cookieless-by-default analytics that also includes session replay, funnels, journeys, and revenue attribution. Fathom is cheaper for many small sites. mrkr answers deeper questions about a single one.
There is no privacy argument to have here. Both tools run without a banner by default, so the decision comes down to breadth against price, and to whether you are measuring one site or thirty.
What happens after the pageview.
Fathom tells you a page got two thousand views. mrkr tells you which source produced them, where they dropped out of the funnel, and what the ones who converted were worth. If that reads as noise, buy Fathom.

FAQ
Are Fathom and mrkr both cookieless?
Yes. Neither sets a cookie in its standard mode, so neither needs a consent banner for it. mrkr additionally offers an optional cookie mode per site for teams that want cross-session identity, and choosing it brings consent obligations back.
Does Fathom have session replay?
No. Fathom has no session replay, no heatmaps, and no funnels at any tier. That is a deliberate product decision on their side, not an oversight.
Which is better for an agency with many client sites?
Fathom, on price. Unlimited sites on a flat plan is hard to beat if each site only needs pageview reporting. mrkr limits sites by plan, so a portfolio of thirty small sites is cheaper on Fathom.
What about data retention?
Fathom keeps data forever on its plans, which is genuinely unusual. mrkr retention is set by plan, from one year on Starter up to three years on Business, and older rows are pruned after that.
Why choose mrkr over Fathom?
Because a pageview count stopped answering your question. Funnels, journeys, conversions, per-visitor detail, revenue attribution, and session replay are all things mrkr does and Fathom does not attempt.
Are the numbers comparable?
Roughly. Both filter bots and both count visitors without cookies by default, so trends line up, but the exact definitions differ and the totals will not match to the unit. Run both for a month if the difference matters to you.
