PostHog

PostHog is an open-source product analytics platform. Learn why product teams use it, who it's best for, when not to use it, and alternatives.

Why this tool?

The problem

Product analytics requires stitching together multiple tools: one for events, one for session replays, one for feature flags, and one for A/B testing.

The old way

Teams use separate tools for analytics, session recording, and experimentation. Data is fragmented, costs add up, and integration is painful.

The better way

PostHog combines product analytics, session replays, feature flags, and A/B testing in one platform. Open source with self-hosting for data control.

What makes it stand out

All-in-one product operating system with transparent pricing and self-hosting. No enterprise contracts required.

Tradeoffs to consider

It is overkill for simple web analytics. Marketing teams focused on attribution may prefer dedicated tools like Google Analytics.

When not to use it

If you only need basic web analytics, PostHog may be overkill. Marketing teams focused purely on attribution may prefer dedicated tools.
