Matomo vs PostHog

What Matomo is

Matomo is web analytics you can self-host, giving you the data without sending it to a third party. It covers most of what mainstream analytics does, with full data ownership. Self-hosting means the raw data never leaves your servers, which removes a whole class of consent and data-transfer questions. The price is that you now run and scale an analytics database, and reporting on high-traffic sites needs real hardware.

What PostHog is

PostHog is the 'all-in-one' product analytics suite for developers and modern startups. Unlike Google Analytics, which focuses on traffic, PostHog focuses on user behavior within your product. It combines powerful features like event tracking, session recordings, heatmaps, and feature flags into a single, open-source platform. It allows teams to build better products by understanding exactly how users interact with every feature, and even run A/B tests to see what works best.

What Matomo is built to do

Self-hosted or cloud

Runs on your own servers or as a managed instance, with the same reporting.

Keeps unsampled visit data in a database you control and can query directly.

Heatmaps and session recording

Adds behaviour tools alongside standard traffic reporting.

What PostHog is built to do

Session Replays

Watch real videos of users navigating your product to find bugs and friction.

Feature Flags

Funnels & Paths

Visualize exactly where users are dropping off in your sign-up or checkout flows.

Group Analytics

Analyze behavior at the company level, not just the individual user level.
