Biggest Movers
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 1.75M live sites, and the top five hold roughly 82% of them. Two tools take about 76% 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, three quarters of the market
Microsoft Clarity sits on roughly 55% of detected sites and Hotjar on about 21%. Crazy Egg follows near 3% and nothing else reaches 2%; Hotjar's and Crazy Egg's figures are the cleaned counts from their own profiles, which strip out for-sale and gambling pages. 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
Over 90 days TWIPLA added about 7,800 net on a base of about 12,000, most of its footprint, and Decibel and Beusable about 6,000 each on bases near 26,000, all far outside the top five. The latest 30 days tell you how to read that: Decibel and Beusable each added and dropped about 7,000 domains to finish nearly flat, and turnover that large in both directions usually means a tag we only catch some of the time. LogRocket's roughly 335 is the largest 30-day net gain anywhere in the category.
Hotjar is where the losses are
Hotjar shed roughly 21,800 more domains than it gained over the latest 30 days, the largest net loss in the category. Microsoft Clarity lost about 18,900 in the same month, so the 30-day drop is broad turnover; what marks Hotjar out is that it's also down about 22,900 over 90 days, while Clarity is up about 34,000. 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.
