Expert Insight: Heatmap & Session Recording Tools Market Share & Momentum
The paid incumbent is losing entry-level ground to a tool Microsoft gives away.
We detect a heatmap or session-replay tool on about 1.6M live sites, and the top five hold roughly 92% of them. Two tools take about 81% between them, and both lead with a free tier, which is most of why this category is more concentrated than the number of vendors suggests.
Two tools, four fifths of the market
Microsoft Clarity sits on roughly 54% of detected sites and Hotjar on about 27%. Crazy Egg follows near 7% and nothing else clears 2%. The concentration is real, but read the second name carefully: Contentsquare acquired Hotjar in 2021, so two of the top four rows belong to one company, and their combined footprint is larger than the table makes it look.
The fastest growth is well down the table
Decibel and Beusable each added roughly 4,000 domains over the latest 30 days on bases near 16,000, which is close to a quarter of their size and the strongest relative growth here. Both sit outside the top five. Six of the 34 tools are excluded from this reading because we only began detecting them inside the window, so we cannot separate growth from a first sighting.
Hotjar is where the losses are
Hotjar shed roughly 8,900 more domains than it gained over the latest 30 days, the largest net loss in the category and several times Microsoft Clarity's. Our switching data points the same way: we see more than twice as many domains moving from Hotjar to Clarity as the other way. Dropped means the tag stopped appearing in our crawl, not a cancelled contract, and a site can run both at once.
Free changes what a share means here
Session replay runs in the browser, so unlike server-side tooling this category is genuinely visible to a crawl and the shares compare like with like. What a detection does not tell you is whether anyone is paying. The two tools at the top have free tiers with generous or unlimited traffic allowances, so their counts include a long tail of small sites that would never appear on a paid vendor's customer list. Read the ranking as reach, and the tools below the top five as the better guide to where money is spent.

Country here is the company's registered location in our enriched data rather than where the site is served from, so read it as a ranking of markets rather than a measure of any single one.

Start from your own size, industry and primary use case rather than from share.
