Session replay and product analytics

See where your website loses people, and why

Heatlytics records visits to your site, then shows where people clicked, scrolled, got stuck and gave up.

What do you want to know about your visitors?

Session replay

Watch a visit back, with every click, scroll and page change on one timeline. Rage clicks and dead clicks are already marked, so you can skip to what went wrong.

One stuck visitor, from start to fix

A short film of how it works on one visit: someone gets stuck, Heatlytics records it and marks the moment, you watch it, and you know what to fix.

  1. Record
  2. Spot the moment
  3. Watch
  4. Fix
40 seconds, no sound. A visitor gets stuck at checkout, Heatlytics records the visit and marks the moment, you watch it, and you fix it.

From a number to the person behind it

  1. A funnel report: fewer sessions reach each step, with a Dropped link beside every step.

    Spot the step

    A funnel shows how many people dropped out, and where.

  2. Recordings filtered to the sessions that dropped out at that funnel step.

    Open the people who dropped

    One click on Dropped lists exactly those sessions, with the filter already applied.

  3. A session’s journey on the checkout page, listing a rage click and a dead click on Apply code.

    Watch why it happened

    The timeline and journey take you straight to the moment it went wrong.

See how common it is

Everyone’s clicks, scrolling and attention on one page, so you can tell one person’s bad day from a button that fails for everybody.

The moments that tell you something’s wrong

Heatlytics spots these in the visitor’s browser and marks them on the replay, the session and the page. These are the default rules.

Quick exit
Leaving the site less than 3 seconds after a page opens.
Dead click
A click after which nothing on the page changes for a second.
Rage click
Three or more clicks in the same spot, less than 300 ms apart.
U-turn
Leaving a page and coming back to the previous one within 10 seconds.
Reload loop
Reloading the same page again and again.

What your visitor types, and what gets recorded

Masking runs in the visitor’s browser, so a masked value never reaches Heatlytics. Each character becomes an asterisk, which keeps the page’s layout in the replay.

Plain text is recorded as typed, unless you mask it.

[email protected]
******************

Masked by default. Only an explicit unmask rule can change that.

**** **** **** ****

Always masked. No setting can unmask it.

***************

Always masked, even after a “show password” toggle.

Check your own pages. Page text, plain text fields and text areas are recorded unless you mask them. Card and bank fields are recognised from their name or label, and long numbers are masked in any text field, but recognition is a best guess.

  • Mask

    Replace an element’s text and input values with asterisks. Images inside it become empty boxes.

    See the code
    <section data-hl="mask">Account details</section>

  • Block

    Replace a whole element with an empty box of the same size.

    See the code
    <div data-hl="block">…</div>

  • Wait for consent

    Recording starts straight away by default. Start in pending, and nothing is recorded or stored until the visitor agrees.

    See the code
    heatlytics.init({ key, host, consent: 'pending' })
heatlytics.optIn()

  • IP addresses

    Heatlytics doesn’t store them. Country and city come from location headers set by Cloudflare at the edge.

For the teams that look after your website

Two script tags, and you’re recording

  1. Copy the snippet with your environment’s key from Settings.
  2. Paste it before the closing head tag on your site.
  3. Open your site. The visit appears in Recordings.

Works with a strict Content Security Policy. For apps, a React Native SDK sends events and screens, without replay.

Read the install page

<script>
  (function (w, host, key) {
    w.heatlytics = w.heatlytics || { q: [] }
    ;['init', 'identify', 'setUserProperties', 'event', 'optIn', 'optOut', 'abort', 'getSessionId', 'setInternal'].forEach(function (n) {
      w.heatlytics[n] = w.heatlytics[n] || function () { w.heatlytics.q.push([n, [].slice.call(arguments)]) }
    })
    w.heatlytics.init({ key: key, host: host })
  })(window, 'https://app.heatlytics.io', 'hl_pub_YOUR_KEY')

Questions you’ll want answered first

Will it slow my site down?

The script loads asynchronously and stays under 40 KB gzipped; a test fails the build if it grows past that. It sends recordings in compressed batches rather than on every action.

What is recorded, and what isn’t?

Page structure and text, clicks, scrolling, page changes and typed input. Password, email, phone, hidden and number fields, and recognised card and bank fields, are replaced with asterisks in the browser, as are long numbers in any text field. Page text and plain text fields are recorded unless you mask them. Heatlytics doesn’t store IP addresses.

How do I keep a page or element out of recordings?

Add data-hl="mask" or data-hl="block" to an element, list selectors, or mask all text. To skip a page altogether, call abort() on it, which stops recording until the next page load.

Can recording wait for consent?

Yes. Start with consent set to pending and nothing is recorded or stored until you call optIn(). optOut() stops recording and clears what was stored in the browser.

Does it work with a strict Content Security Policy?

Yes. There’s a guide listing what to allow, and the script tag can carry a pinned integrity hash, so the browser refuses it if its bytes ever change.

Does it work on single-page apps?

Yes. Route changes made without a page load are tracked as page changes.

What doesn’t it do yet?

There’s no session replay for mobile apps, and there are no saved segments, retention reports, alerts, error tracking, AI analysis, integrations, single sign-on or two-factor sign-in yet. Each feature page says what’s missing there.
