Mrkr vs Microsoft Clarity.

Clarity is free, unlimited, and good. It also needs a consent banner, tells you nothing about where your traffic came from, and makes Microsoft the controller of your visitors' data. Here is the honest trade.

Should I use Microsoft Clarity or Mrkr?

Use Clarity if your budget is zero and you want unlimited session replay and heatmaps. Use Mrkr if you need analytics rather than only behaviour, want to skip the consent banner, or cannot hand your visitors' data to Microsoft. Clarity wins on price. Mrkr wins on consent, attribution, and ownership.

This is not a close feature comparison dressed up as a hard choice. Clarity is a strong free product and pretending otherwise would waste your time. The question is whether the three things it costs you are things you care about.

The question Clarity cannot answer.

Clarity shows you what a visitor did. It has no traffic sources, no referrers, and no UTM campaign reporting, so it cannot tell you which channel produced the person you just watched.

What free actually costs.

The consent tax

Clarity needs a banner, and the people who decline are not a random sample of your traffic.

No answer to where they came from

No campaign, referrer, or landing page, so behaviour never connects to spend.

Microsoft is the controller

Interaction data sits on Microsoft's infrastructure under Microsoft's terms.

Not the system of record

Nobody reports monthly numbers out of Clarity, so it runs beside a second tool.

Side by side.

When Clarity is the right answer.

Solo founder, no budget, no EU traffic, no procurement process? Clarity is an excellent tool and you should use it.

Unlimited replay for nothing

There is no session cap and no bill. That is a real offer, not a trial.

Heatmaps Mrkr does not have

Click and scroll maps are included. Mrkr ships no heatmaps at any tier.

Nothing to evaluate

No plan to pick and no procurement call. It is running in ten minutes.
