PostHog
Product analytics suite with session replay, experiments, feature flags and surveys.
Disclosure: some links on this page are affiliate links. If you buy through one, ROAScal may earn a commission at no extra cost to you. It never decides what we recommend or what we say about it. How this works.
PostHog bundles product analytics, session replay, feature flags, experiments, error tracking, surveys and a data warehouse. It has a free tier that resets monthly, including 1M analytics events and 5K session recordings, with no credit card needed. Usage beyond that is billed per product.
Best for
SaaS founders who want to see what paid traffic does after sign-up, including activation and retention.
Not for
Media buyers wanting ad-level attribution and ROAS dashboards, as it is a product analytics tool.
How to get your money’s worth
- 01Capture UTM parameters at sign-up so you can compare activation and retention by campaign.
- 02Watch session replays of paid landing page visitors who bounce, to find friction before changing ads.
- 03Set billing limits per product so a traffic spike does not push you beyond the free allowance unnoticed.
