Best data analytics tools for founders
What's working. What isn't. All 20 compared on what they actually cost, read from each vendor's own pricing page on 28 August 2026. 13 have a real free tier.
Ties traffic to revenue, so you see which posts brought paying customers rather than which brought visitors. It is what runs on this site.
If you only look at three
The rest of the data analytics table is worth reading, but these are the three most founders should be choosing between.
- 1
Plausible AnalyticsFrom $7.50/moThe privacy-first default at $7.50, open source, and you can host it yourself for nothing if you ever want to.
- 2
DataFastFrom $9/mo · our pick · we earn on thisTies traffic to revenue rather than counting visits, which is the question most founders actually have. We are paid on this one.
- 3
PostHogFreeProduct analytics with a free tier generous enough to carry a small company for a long time.
More specific questions
The short version
Eighteen tools, and the honest split is between knowing how many people came and knowing which of them paid. Plausible, Fathom, Pirsch, Umami and Simple Analytics are privacy-first replacements for Google Analytics, they all do roughly the same job for between $4 and $8, and choosing among them is mostly taste. Baremetrics and ChartMogul are revenue analytics answering a different question at $49. PostHog and Mixpanel are product analytics with free tiers generous enough to carry a small company for a long time. DataFast is our pick because it ties traffic to revenue in one place, which is the question most founders actually have. It is also a tool we earn commission on, and we would rather say that here than at the bottom of the page: judge the pick knowing it. If that bothers you, OpenPanel at $4.17 and Plausible at $7.50 do the traffic half well and we have no commercial relationship with either. Eleven of the eighteen have a free tier, so there is no reason to pay before you have traffic worth measuring.

Prices are the cheapest paid plan, annual rate where published. A price band counts a free tool as zero, and leaves out anything whose price is not published, because we cannot say an unknown price fits a budget.
