PostHog

What it is.

PostHog answers the question that starts after signup: what did this account do, and did they come back. Analytics, session replay, feature flags, experiments, surveys, plus error tracking sit in one workspace.

Each product has a free monthly allowance that resets: 1 million analytics events, 5,000 session recordings, 1 million feature flag requests, 1500 survey responses and 100,000 tracked exceptions. Past those you pay per unit, and the rate drops as volume climbs.

What you get.

  • 1 million analytics events a month, tied to a person and not a browser.
  • 5,000 session recordings a month, filtered by the same properties as your events.
  • 1 million feature flag requests, so a percentage rollout costs nothing.
  • 1500 survey responses and 100,000 tracked exceptions on the same free tier.
HOW TO USE IT

How to set it up.

1

Install the JavaScript snippet or the SDK for your stack, then identify logged-in users so events attach to a person.

2

Agree your event names before you send the first one, since renaming later splits the history.

3

Build one funnel for signup and one for the core action, and leave everything else until those two are trusted.

4

Turn on session replay and link it to the funnel, so a drop-off step opens the recordings behind it.

5

Put your first feature flag behind a percentage rollout, and read the funnel by flag variant.

6

Watch the billing page in month two, because 5,000 recordings a month is the allowance most teams pass first.

Use cases

Did they reach the value moment

Define the event that means activation, then see which accounts hit it.

Test a change on a slice

Wrap the change in a flag, expose it to some users, and read the result on the same events.

Replay the drop-off

Watch recordings for the users who left before activation.

Best for

Early-stage B2B products

1 million events and 5,000 recordings a month covers a product with a few thousand active users, at no cost.

Replacing three tools

Analytics and session replay on one install removes the identity mismatch you get when three tools track the same user.

Product-led growth measurement

Person-level events let you see which accounts reached the value moment, which session analytics cannot answer.

Questions about Analytics & Attribution

Is product analytics worth it before product-market fit?
How is session analytics different from person analytics?
Before you start
  • A developer to install the snippet or the SDK for your stack.
  • An agreed event list, since renaming later splits the history.
Strengths
  • 1 million events, 5,000 recordings and 1 million flag requests a month on the free tier, with each product metered separately.
  • Flags and experiments are included, so an A/B test needs no second vendor.
  • Per-unit rates are published in full, including the price at every volume band.
Limitations
  • Session replay is usually the first allowance to run out, at 5,000 recordings a month.
  • Usage-based pricing means a traffic spike shows up on the bill, so set a billing limit while you are still free.
  • Autocapture collects a lot of events by default, which burns the analytics allowance faster than a planned event scheme.
Skip this if
  • You already pay for product analytics and a separate flagging tool, and both are wired in.
Ideal for
  • Product-led growth teams
  • Product marketers
  • Engineering-adjacent marketers
