Mrkr vs Umami.
Umami is MIT-licensed and free on your own server. Mrkr is hosted, proprietary, and does more once it is running. The honest question is whether you want to operate an analytics server at all.
What is the difference between Mrkr and Umami?
Umami is MIT-licensed cookieless analytics you can self-host for free, covering pageviews, sources, events, and funnels. Mrkr is a hosted proprietary product that adds session replay, cohorts, retention, and revenue attribution, cookieless by default. Umami gives you ownership of the software. Mrkr gives you capability without operations.
If the licence is the point, this comparison is already decided. Umami is MIT, Mrkr is closed source and hosted only, and no feature list changes that. What follows is for readers who are weighing the running cost against what the extra features are worth.
What the subscription actually buys.
Session replay, cohorts and retention, per-visitor timelines, revenue attribution, Core Web Vitals, a managed first-party proxy, and the absence of a database to back up. Whether that is worth a monthly fee is a genuine judgement call.

Where Mrkr is better.
Replay, cohorts, revenue
Umami counts and segments well. It records no sessions and attributes no revenue.
Nothing to keep alive
No Postgres, no upgrades, no outage that leaves a gap you cannot backfill.
Adblock resistance, managed
The tracker serves from your own subdomain. On Umami that is a reverse proxy to maintain.
Bots separated and shown
One live Mrkr site logged 2,946 human pageviews against 12,146 filtered bot hits.
