PostHog is great at product analytics. What about your revenue?

PostHog shows what people do in your product, and lets you build revenue views yourself from Stripe and other sources. Sumly gives you the revenue side ready: MRR, churn and fees from billing, every payment tied to the visit or install that brought it, across all your projects.

Where PostHog is the better choice

PostHog suits a product team that wants to see what people do inside the product, test changes with flags and experiments, and build its own revenue views with SQL.

  • Session replay with console and network logs.
  • Feature flags, experiments and surveys.
  • A data warehouse: Stripe, RevenueCat, the stores and your databases in one place, queried with SQL.
  • Heatmaps, error tracking and PostHog AI across all of it.
  • A free tier on every product.

Where Sumly fits

Sumly suits a founder who wants the revenue picture without building it: MRR, churn and fees, which visits and installs paid, for several products at once.

  • You want MRR, churn, refunds and fees on one screen, without writing SQL.
  • You sell on the web and in the App Store or Google Play, and want both added up.
  • You run several products or companies and want each apart and all of them together.
  • You want each payment tied to the visit or app install that brought it, by first touch, last touch or linear.
  • You want a monthly package for your accountant.

Using Sumly next to PostHog

Nothing has to be switched off. PostHog keeps product analytics, replay and flags; Sumly reads your billing with its own read-only key and counts visits with its own script.

Sumly has no PostHog connection: the two run side by side, each with its own script.

  1. 1Create a project in Sumly and add its script next to PostHog's.
  2. 2Connect Stripe, Paddle, RevenueCat, the App Store or Google Play with a key that can only read. The first read takes up to three years of payments.
  3. 3Stripe Payment Links, pricing tables and buy buttons carry the visitor by themselves; checkouts your server makes link through the buyer's return.
  4. 4Keep using PostHog for what people do in the product, and Sumly for where the money comes from.

Sumly and PostHog: questions

Does PostHog have revenue analytics?

Yes, in beta. It works out MRR, churn and LTV from Stripe, or from revenue events your code sends, and you use them in insights, SQL or PostHog AI. Stripe customers are tied to people by adding the PostHog id to their metadata. Chargebee, Polar and RevenueCat are marked coming soon.

Does Sumly replace PostHog?

No. Sumly has no session replay, feature flags, experiments or surveys. It covers revenue and where it comes from, and runs next to PostHog.

Can Sumly read my PostHog data?

Not today. Sumly counts visits with its own script and reads payments from your billing providers.

What does each cost?

Sumly starts at $9 a month, and Growth is $19 for 500k visits a month, each with a 14-day trial and no card. PostHog has a free tier on every product each month and then charges per unit, as its pricing page said on 9 November 2026.
