Mrkr vs Amplitude.
Amplitude is built for an analytics practice with a data team behind it. Mrkr is built for the team that wants funnels, retention, and replay working by lunchtime.
What is the difference between Mrkr and Amplitude?
Amplitude is enterprise product analytics: deep behavioural cohorting, governed event taxonomies, and analysis across very large event volumes. Mrkr is privacy-first web analytics with funnels, cohorts, retention, and session replay that work from a single script tag. Amplitude is cookie-based. Mrkr is cookieless by default.
Amplitude answers questions a product organisation asks over quarters. Mrkr answers questions a small team asks on a Tuesday: which channel brought this signup, where did the funnel leak, what did that session look like. Different questions, and the tools follow from them.
Retention on the first day.
Mrkr groups visitors by the week they first arrived and shows how many returned. Without a cookie, a return visit resolves within a rolling daily window, so a twelve-week curve is directional rather than exact. Cookie mode is available per site when exactness matters more than the banner.
Where Mrkr is better.
Useful before instrumenting
Amplitude with no events is an empty workspace. Mrkr is already a full dashboard.
No banner by default
Amplitude sets a persistent identifier. Mrkr counts people without storing anything.
Acquisition is built in
Referrers, campaigns, AI assistants, and bots, uninstrumented. Amplitude knows only what you send.
Replay in the same dataset
Recordings carry their source and revenue, so you can watch a campaign that did not convert.

Judge it on real data
Funnels, cohorts, journeys, and replay all run on the live demo dataset. If the depth is not enough for your question, you will know in two minutes.

Where Amplitude is genuinely better.
Behavioural cohorting
Everyone who did A then B but not C, tracked forever. Mrkr has nothing approaching it.
Analysis depth
Pathfinding and statistical tooling for analysts. Mrkr stops at funnels, cohorts, retention.
Governance at scale
Taxonomy enforcement and event approval across a large org. Mrkr has workspaces and roles.
Cross-platform identity
One user across web, iOS, and Android. Mrkr is web only and does not follow across days.
