Expert Insight: Product Analytics Tools Market Share & Momentum
PostHog is pulling away from Amplitude on live-site counts.
PostHog is on about 45% of the 236K live sites where we detect a product analytics tool, Amplitude about 31% and Mixpanel about 11%. PostHog added roughly 4,600 net domains in 30 days while Amplitude lost about 3,200; over 90 days the gap is +8,800 against -1,900.
Three tools, 86% of the category
PostHog (~45%), Amplitude (~31%), Mixpanel (~11%), then Pendo (~6%) and Heap (~4%). Only 12 tools register at all, which makes this one of the most concentrated categories we track. 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
PostHog: about 9,800 adds against 5,200 drops in 30 days. Sensors Data (+116) and OpenPanel (+45) are the other positive lines, both small. Amplitude, Mixpanel, Pendo and Heap all lost domains net.
Amplitude churns at 10% of its base a month
Amplitude dropped from about 7,300 sites in 30 days, 10% of its base, roughly double PostHog's 4.9% and Mixpanel's 4.9%. Some of that is trial and free-tier tags coming off marketing sites; some is real replacement. The 90-day view (-1,900) says the losses aren't a one-month blip.
The open-source option is winning installs
The category grew about 7,700 net over 90 days, and PostHog accounts for more than all of it. Mixpanel is slightly up over 90 days (+660) after a flat month, Pendo and Heap slightly down. If you're tracking who product teams pick for new projects, the answer in this data is PostHog.
