Session replay, with no cookie banner by default.
Watch what actually happened in a session, then trace it back to the campaign that paid for it. Cookieless by default, masked by default, and bundled into a $5 plan rather than sold as a separate product.
In short
What is privacy-first session replay?
Session replay records how a visitor moved through your site, then plays it back as video. Privacy-first replay does it without a persistent cookie or a device fingerprint, and masks form input in the browser before anything is sent. mrkr records this way by default, so no consent banner is required.
The recording is not a screen capture. mrkr captures the structural changes to the page and replays them, which is why a session costs kilobytes rather than megabytes, and why text can be masked before it ever leaves the visitor’s browser.
The session behind the number.
A replay opens with its own timeline: every page view, click, scroll, and rage click in order, with the source and campaign that brought the visitor in sitting beside it.
Scrub to the moment a session went wrong instead of watching it end to end.
What replay is actually for.
Explain a funnel drop-off
A funnel says 38% leave at payment. Open the sessions that dropped and you see why.
Reproduce a bug you cannot reproduce
Watch the session instead of reading a support thread. Exact sequence, browser, viewport.
See whether the page reads
A timeline shows which pages and events happened. Replay helps explain whether visitors stalled, skimmed, or hunted.
Judge a campaign properly
Every replay carries its source, campaign, and landing page. Good numbers plus bad sessions is a warning.
Compared
Who else does privacy and replay together. Most privacy-focused analytics tools do not sell session replay at all, and most replay tools are not privacy-focused. This is the honest state of the field.

Competitor details checked against their own pricing and feature pages on 2026-08-24. mrkr has no heatmaps; if heatmaps are the job, Hotjar or Clarity is the better tool.
Live demo
Watch a real replay right now. The live demo carries recorded sessions on a real dataset. Open a visitor, pick a session, and play it back. No signup and no card.
Open the live demoHow the recording stays private.
Masked in the browser
Text inputs and password fields are replaced before the payload is built, so what was typed never reaches mrkr.
An identifier built to expire
The visitor signal is salted and rotates every 24 hours. Recordings are deleted on your plan's retention schedule.
What it cannot do
Cookieless mode cannot link one person's sessions across weeks. Cookie mode is a per-site switch, and it does need consent.
FAQ
Does session replay need a cookie banner?
Not in mrkr's default cookieless mode. Replays are keyed to a rotating, salted signal rather than a persistent cookie or a device fingerprint, so there is no persistent identifier to disclose and no consent banner required in the EU, UK, or California. Turning on cookie mode changes that, and then you do need consent.
What does mrkr mask in a replay?
All text inputs, password fields, and anything you mark are masked before the recording leaves the browser. The masking happens client side, so the unmasked values never reach mrkr's servers at all.
How is this different from Hotjar or Microsoft Clarity?
Both set cookies and both are built around heatmaps and qualitative research. mrkr is an analytics product first: replays sit next to your sources, funnels, and revenue, so you can jump from a drop-off in a funnel straight to the sessions that dropped.
Do Plausible or Fathom have session replay?
No. Neither Plausible, Fathom, Simple Analytics, nor Pirsch sells session replay at any price. If you want privacy-friendly analytics and replay in one tool, the field is small.
How long are replays kept?
As long as your plan's retention window: 1 year on Starter, 2 years on Pro, 3 years on Business. Replays are pruned automatically when they age out.
How much does session replay cost?
It is included on every paid plan, starting at $5 a month on Starter, which covers 100K pageviews. There is no per-session charge and no seat charge, and recordings are not metered at all.
