Session replay is one of the easiest tools in the stack to buy: a script on the site, often a free plan, and recordings of real visitors getting stuck almost at once. About one in five interviewed companies that list their stack runs one. The buyers using it describe a tool that earns its place in single moments — the recording that explains a drop in conversion, the bug nobody could reproduce — and then sits unwatched, because the recordings pile up faster than anyone can look at them.
What is session replay software?
Session replay software captures visitor interactions on a website or app — clicks, scrolls, taps and errors — and reconstructs them into a playback that shows how someone navigated a page or ran into a problem. It typically records interaction data rather than conventional screen video, and sensitive information can be masked or excluded. Most tools also produce heatmaps, which add up where many visitors click and how far they scroll.
Buyers name Hotjar, Contentsquare, FullStory, Microsoft Clarity and Quantum Metric most, and they use them beside a web analytics tool rather than instead of one. One buyer puts the split simply: “Google Analytics is the what, and then Contentsquare would be the why.”
What the interviews add is how those tools are actually bought and used:
In these interviews session replay is bought mainly to find friction and fix bugs, and the market splits by company size: free and self-serve tools at smaller companies, enterprise digital-experience platforms at large ones, and very few companies running both.
The complaint buyers raise most, slightly ahead of cost, is recordings nobody has time to watch. AI that summarizes sessions is the answer vendors are offering; a small number of companies use it, others say they want it, and experiences so far are mixed.
What is the difference between session replay, heatmaps and digital experience analytics?
Session replay shows one visit; a heatmap adds up many; digital experience analytics adds scoring and alerting on top. Most tools now do the first two, and the enterprise platforms do all three.
Session replay is rarely a company's only behavioral data. Companies running a replay tool are half as likely again as the companies interviewed overall to run GA4, and nearly twice as likely to run an experimentation tool such as Optimizely, AB Tasty or Adobe Target — replay explains what the analytics shows and supplies the ideas the testing tool tries.
Replay also arrives bundled. Several buyers get it inside an experimentation tool or a product analytics platform such as Amplitude, and a few say the bundled version is sold as an upgrade rather than included.
Session replay
A reconstructed playback of one visitor's interactions — clicks, scrolls, taps and errors — used to investigate where they ran into friction.
Heatmaps
Many visits added up into one picture of where people click, move and stop scrolling on a page.
Digital experience analytics
Replay and heatmaps plus friction scoring, error detail and alerting, from enterprise platforms such as Contentsquare, Quantum Metric and Glassbox.
Who uses session replay software?
Ecommerce, digital and product teams, with design and engineering close behind. Buyers in market for these tools are nearly twice as likely as the companies interviewed overall to hold ecommerce or digital titles, and about three times as likely to hold product or UX titles. The contract usually sits with one team while several use the recordings: designers checking layouts, developers chasing errors, support looking up a complaint.
Which tool a company runs follows its size. Among interviewed companies using a free or self-serve tool such as Microsoft Clarity or Hotjar, more than half have under $250 million in revenue; among those using an enterprise platform such as Contentsquare, Quantum Metric or Glassbox, about two-thirds have more than a billion, against fewer than half of all interviewed companies.
What do companies use session replay for?
Five main jobs, led by finding friction. Among companies that describe what they use it for, these appear in this order, and the same recordings often serve several:
- Finding friction and conversion problems
- Reproducing and fixing bugs
- Looking up a customer's visit for support
- Generating and checking A/B test ideas
- Design research and proving a problem to colleagues
Mobile app replay and merchandising reads are smaller, separate jobs.
Finding friction and conversion problems
Where visitors hesitate, rage-click, abandon a form or drop out of checkout, usually owned by ecommerce and digital teams.
One buyer describes the payoff: “you can see friction points and where people are running into dead ends or rage clicking.”
Reproducing and fixing bugs
Watching the visit that produced an error, so developers can see the steps rather than guess them.
As one puts it: “sometimes I can't reproduce myself, so it's super nice to be able to watch their session.”
Looking up a customer's visit for support
Pulling up the session behind a complaint, sometimes straight from the help desk.
One buyer on the support use: “customers will complain to customer service and we can watch what they did.”
Generating and checking A/B test ideas
Recordings as the source of hypotheses for the experimentation tool. A sporting-goods brand watched a shopper leave with a cart just under the free-shipping line and built an add-on offer for exactly that gap: “I came up with that idea after looking at a screen recording.”
Design research and proving a problem
Checking how visitors engage with new designs, and showing colleagues the recording instead of arguing about the numbers. A consumer-finance company could not explain a drop in click-through until the replay showed why: “we noticed through Glassbox that that banner was covering up a CTA.”
The trouble starts after the first insight. The complaint buyers raise most often is that the recordings go unwatched — “it ended up being a software that we're paying that no one was looking at,” says one — and the volume is the reason: “There's no way it's humanly possible to go through those recordings each month.” AI is the answer vendors are offering. A small number of companies use features that summarize recordings or flag friction — “Now we can see the summary of all 50 sessions per page within one minute,” one says — and others say they want them. Experiences are mixed: one buyer who praised an AI summarizer found months later that “it breaks like half of the time.”
Which session replay tools do buyers rate highest?
Glassbox rates around 8 and Quantum Metric 7.8; Hotjar, Microsoft Clarity and Contentsquare all sit at 7.4, FullStory at 7.2 and Crazy Egg around 7. The free tool rates level with the paid ones, which says as much about expectations as about features — “If we were paying for it, I think the rating would be lower,” one Microsoft Clarity user admits.
| Tool | Rating | What it means here |
|---|---|---|
| Glassbox | around 8 | Too few buyers for a decimal. Enterprise replay, concentrated in banks, insurers and other regulated businesses. |
| Quantum Metric | 7.8 | Enterprise replay with error detail and alerting, praised for the depth of its replay and an easy setup. |
| Hotjar | 7.4 | The most-named tool; affordable heatmaps and recordings a marketer can run, now owned by Contentsquare. |
| Microsoft Clarity | 7.4 | Free; several companies dropped a paid tool for it, and its complaints are about limits beyond basic use. |
| Contentsquare | 7.4 | Enterprise digital-experience analytics, praised for journey visualization; cost is what pushes buyers away. |
| FullStory | 7.2 | Enterprise replay and analytics for product and digital teams, praised for reproducing issues; priced at a premium. |
| Crazy Egg | around 7 | Too few buyers for a decimal. Low-cost heatmaps with light testing. |

What does session replay cost, and what gets in the way?
Many plans limit recorded sessions or charge by usage, and pricing also varies by features and service level. Buyers on capped plans sometimes capture only a small share of their traffic. No prices are published here.
Session limits can mean a lower-tier plan captures only a sample of a site's traffic: “So we were basically capturing 1.6% of our site,” one buyer says of a capped plan, and another describes enterprise replay running “only for a percentage of traffic. And that's obviously budgetary things.” That is part of why several companies have moved to free Microsoft Clarity — moves toward it far outnumber moves away — while some buyers in market for a replacement want more depth or reliability than it gives.
Three other things slow it down. A few buyers say the script slows their site. Privacy is raised rarely but decisively: it contributed to one company not renewing, and at another the approval went to IT to check “potential information that could be leaked,” a review that took months. And several treat the output as a guide rather than evidence — “It's good to see which way the wind is blowing, but I would not use it to make decisions,” says one, which is why replay sits beside an analytics tool rather than replacing it.

Get my review →Should you buy session replay software?
Start by identifying who will review sessions and what problems they need to solve. For straightforward usability and conversion questions, a free or self-serve tool may be enough. Enterprise platforms become more attractive when teams need deeper error analysis, automated alerts, more integrations or broader support.
Three things follow from the interviews; the recommendations are ours, not practices buyers describe. First, make reviewing the recordings someone's job, with time set aside, since unwatched recordings are the complaint buyers raise most. Second, check what share of traffic a plan actually records, because a sampled plan can miss the visit you need. Third, get privacy and security review started before the trial, and confirm how personal data is masked, since that review is where purchases stall.

Common questions
What is session replay software?
Session replay software captures visitor interactions on a website or app, including clicks, scrolls, taps and errors, and reconstructs them into a playback that shows how someone navigated a page or ran into a problem. It typically records interaction data rather than conventional screen video, and sensitive information can be masked or excluded. Most tools also produce heatmaps, which add up where many visitors click and how far they scroll. In buyer interviews it is used mainly to find where visitors struggle and to reproduce bugs, alongside a web analytics tool such as GA4 or Adobe Analytics.
What is the difference between session replay and heatmaps?
Session replay shows one visitor's visit as a recording; a heatmap aggregates many visits into a picture of where people click, move and stop scrolling. Most tools offer both. Enterprise digital-experience analytics platforms such as Contentsquare, Quantum Metric and Glassbox add friction scoring, error detail and alerting on top.
What is session replay used for?
Mostly for finding friction. Among companies that describe what they use it for, more than half use it to see where visitors struggle or drop off, about three in ten to reproduce and fix bugs, and smaller groups to look up a customer's visit for support, to generate A/B test ideas and to check designs. Several also use the recordings to convince colleagues that a problem is real.
Which session replay tools do companies use?
Buyers name Hotjar, Contentsquare, FullStory, Microsoft Clarity and Quantum Metric most, then Glassbox, Crazy Egg and Heatmap.com. Use follows company size: free and self-serve tools such as Microsoft Clarity and Hotjar are used mostly by smaller companies, and enterprise platforms such as Contentsquare, Quantum Metric and Glassbox, used mostly by companies over a billion dollars in revenue. Few companies run one of each.
Is Microsoft Clarity as good as paid session replay tools?
For many smaller teams it is enough. Buyers rate Microsoft Clarity 7.4, level with Hotjar and Contentsquare, and several companies dropped a paid tool for it on cost, far more than moved the other way. Its complaints are about limits beyond basic use, and some buyers in market for a replacement want more depth or reliability than it gives.
Can AI watch session recordings for you?
It is starting to. A small number of companies in these interviews use AI features that summarize recordings or flag friction, in tools including Microsoft Clarity, Quantum Metric, FullStory and Contentsquare, and others say they want it, because watching recordings is the work nobody has time for. Experiences are mixed, and some buyers who tried it found it unreliable.
Is session replay a privacy risk?
Few buyers raise it, but where they do it can block or delay a purchase. In these interviews privacy concerns contributed to one company not renewing a replay tool, and another company's approval went through an IT review of what data could leak that took months. Masking personal data and getting security review early are our recommendations, not practices buyers describe.
