Amplitude vs PostHog

What Amplitude is

Amplitude is the world's #1 ranked product analytics platform, trusted by massive brands like Ford, Walmart, and Burger King. It goes beyond simple traffic tracking to provide deep insights into the 'behavioral' patterns that drive growth and retention. With its 'Digital Analytics Platform' approach, it combines analytics, A/B testing, and a customer data platform into one powerhouse. It is designed for teams that want to turn every user interaction into an opportunity for product-led growth.

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 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.
