Expert Insight: Product Analytics Tools Market Share & Momentum
PostHog is pulling away from Amplitude on live-site counts.
PostHog is on about 47% of the 298K live sites where we detect a product analytics tool, Amplitude about 27% and Mixpanel about 9.5%. Both leaders lost domains over the latest 30 days, PostHog about 4,500 net and Amplitude about 4,100, but over 90 days PostHog is still up about 7,000 while Amplitude is down about 2,000.
Three tools, 84% of the category
PostHog (~47%), Amplitude (~27%), Mixpanel (~9.5%), then Pendo (~6.5%) and Heap (~3.5%). Only 16 tools register at all, one of the shortest lists we publish. The ranking is by websites detected, so it likely favours tools that also run on the marketing site, not only inside the logged-in product.
PostHog is the only large gainer, and only over 90 days
Over 90 days PostHog added about 7,000 net, the only large gain in the category; the next, a second Heap row at about 2,200, mostly arrived inside the window. The latest 30 days went the other way: about 11,700 adds against 16,200 drops for PostHog. OpenPanel (+155) and Countly (+10) are the only positive lines on the month, both small. Amplitude, Mixpanel, Pendo and Heap all lost domains net on both windows.
The two leaders churn at the same rate
Amplitude dropped from about 9,400 sites in 30 days and PostHog from about 16,200, each close to 12% of its base, against about 7.6% for Mixpanel. With nearly every row in the category down over the same month, read most of it as trial and free-tier tags coming off marketing sites and ordinary crawl turnover, not replacement. Amplitude's 90-day view (about -2,000) says its losses aren't a one-month blip, while PostHog is still up on the same window.
The open-source option is winning installs
The category grew about 4,100 net over 90 days despite a 30-day drop of about 14,800, and PostHog accounts for more than all of the 90-day gain. Mixpanel is now down on both windows (about -1,100 over 90 days), and Pendo lost about 2,900 over the quarter, all of it in the latest month. If you're tracking who product teams pick for new projects, the answer in this data is PostHog.

FAQ.
What is Product Analytics software?
Product Analytics covers the tools a site can load or configure to handle this part of its stack. We detect one of the 16 product analytics tools in this category on 297,586 live sites. A detection means we found the technology on the site, which is not the same as a paid account.

PostHog is the most widely detected product analytics tool at 46.98% share, on 139,813 sites. The largest share of those sites belongs to Software Development companies, and to businesses in the 1-10 employee band.
Which industries use product analytics software the most?
The industries with the most detected sites in this category are Software Development, Technology, Information and Internet, IT Services and IT Consulting, Real Estate, Financial Services.

Which countries have the highest adoption of product analytics tools?
We detect the most product analytics sites in United States, United Kingdom, Germany, India, Canada. 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.
How do I choose the right product analytics platform?
Start from your own size, industry and primary use case rather than from share. PostHog, Amplitude and Mixpanel are the three we detect most often in this category, which tells you what is common, not what fits you. Compare their integrations, pricing tiers and support commitments against the workflow you actually run, and check each vendor's own documentation for current capabilities.
