Four small things are worth doing while this chapter is fresh — together they take about ten minutes:
- Create a PostHog account on the right region for your users (US or EU) — it's the one decision here that's hard to undo (see the US-or-EU piece).
- Create one project, keeping your marketing site and your app in the same one — the payoff is seeing the whole journey, from first visit to paying user, in one place.
- Find your project API key (it starts with
phc_) — you'll want it in the instrumentation chapter, and it's safe to expose publicly: it can write events but not read your data. - If you evaluated alternatives, consider writing one line on why you chose PostHog (or didn't). A growth team can always answer "why this tool" — and the note earns its keep when someone asks in six months.
That's all the setup for now. The next chapter is the part most teams skip and later wish they hadn't: deciding what to measure before wiring anything up.

- PostHog — Product analytics docs — the reference for the half of the tool this course lives in.
- PostHog — the product analytics overview — the shorter framing of the same, with the current feature surface.
- PostHog vs GA4 — the candid side-by-side; useful ammunition for the "we already have GA" conversation.
- Google — the GA4 event model — read Google's own docs to see the difference from a product-analytics event model first-hand.
- PostHog vs Mixpanel — the all-in-one vs point-tool trade, feature by feature.
- PostHog — Session replay docs — setup and the debugging workflow you'll use in the daily-dashboard chapter.
- PostHog — Feature flags docs and Experiments docs — the ship-behind-a-flag half of the loop, and the instrument behind the experimentation program.
- posthog.com/pricing — the current free-tier numbers; verify before you rely on the table above.

Why PostHog vs the alternatives
A growth team should be able to say why it chose its tools. PostHog is this course's default but not the only honest choice — the real landscape (Mixpanel, Amplitude, GA4, Segment, Heap, Statsig, Plausible, build-your-own) and where PostHog wins and loses.

The five numbers that matter, the order to fix them in, the one metric that predicts whether a user stays, how to find yours, and the other frameworks worth knowing — in six short pieces.
