PostHog has all, or almost all, the features needed for user analytics. I particularly appreciate their very generous free plan. It's developer-friendly with good documentation and customer support. The initial setup is pretty easy, which is a big plus.

I use PostHog for analytics and I really appreciate that it's very developer-friendly. The dashboard UI is very nice, and I love that it has session replay natively integrated, so there's no need to install another package. The initial setup was very easy, which was a big plus for us.

As a founder, PostHog gives me day-to-day insights into issues users would never tell me about themselves. I can see where people struggle and act on it before it becomes a complaint. Feature flags have also been hugely valuable even when I'm not running big experiments, I use them to toggle features on and off or push status messages to users. It's a simple but powerful way to stay in control of what's live.
