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.
