Posthog vs Google Analytics — For Builders Who Actually Ship
Posthog is for teams that need to understand user behavior to build better products. Google Analytics is for marketers who need to track traffic and conversions.
Posthog
Posthog gives you the data you need to make product decisions without needing a data scientist. Google Analytics gives you reports that look impressive but are often useless for product development.
Two Different Philosophies
Posthog is built for product teams that need to understand how users interact with their product. It's designed to answer questions like 'What features are users actually using?' and 'Where are they dropping off?' Google Analytics is built for marketers who need to track traffic sources, conversions, and ad performance. It's great for answering questions like 'How many people visited my site?' and 'Which ad campaign is driving the most sales?'
Where Posthog Wins
Posthog's autocapture feature automatically tracks every click, pageview, and form submission without you having to write any code. This means you can start getting insights immediately, without waiting for your engineering team to instrument your app. Posthog's funnels are also much more flexible than Google Analytics' conversion funnels. You can create funnels based on any event, not just pageviews, and you can see exactly where users drop off in real-time.
Where Google Analytics Holds Its Own
Google Analytics is still the king of traffic analysis. If you need to know where your visitors are coming from, what devices they're using, and how they're interacting with your marketing campaigns, Google Analytics is the tool for you. It's also free for most use cases, which is hard to beat. Posthog's free tier is limited to 1 million events per month, while Google Analytics is free for up to 10 million hits per month.
The Gotcha: Switching Costs
If you're already using Google Analytics, switching to Posthog will require you to re-instrument your entire app. Posthog's autocapture feature can help with this, but you'll still need to set up custom events for things like user sign-ups, purchases, and other key actions. This can be a significant time investment, especially if you have a large, complex app. On the other hand, if you're starting from scratch, Posthog is much easier to set up and maintain.
If You're Starting Today
If you're building a new product and you need to understand how users are interacting with it, start with Posthog. Its autocapture feature will give you immediate insights without any code changes, and its funnels will help you identify where users are dropping off. If you're already using Google Analytics and you're happy with it, stick with it. But if you're finding that Google Analytics isn't giving you the insights you need to make product decisions, it's time to switch to Posthog.
What Most Comparisons Get Wrong
Most comparisons focus on the fact that Google Analytics is free and Posthog is paid. But that's missing the point. The real question is: what are you trying to learn? If you're trying to learn how to improve your product, Posthog is the better tool. If you're trying to learn how to improve your marketing, Google Analytics is the better tool. It's not about price, it's about purpose.
