Accessible enterprise grade analytics

PostHog has been a fantastic surprise. I initially expected it to be a heavy and complex analytics tool, but it turned out to be incredibly accessible—especially for early-stage projects. The setup was straightforward and fast, and it integrated seamlessly with my Next.js app, performing far better than expected. What really stands out is how complete the platform is. It has every feature I could need—from product analytics to session replays, feature flags, A/B testing, and more—all in one place. Usually, you need to string together multiple tools to get this level of insight, but PostHog just delivers everything out of the box without feeling bloated. It’s rare to find a tool this powerful that still feels lightweight and developer-friendly. Highly recommended for startups and scale-ups alike.

If I had to pick something, it would be the documentation. It’s not bad by any means, but I think it could be a bit better organized and more detailed in some areas—especially for edge cases or advanced use. That said, this is really just nitpicking.

PostHog helps us cover multiple crucial areas in one place—product analytics, web analytics, and session replays. Instead of juggling separate tools, we get a unified view of how users interact with our app. The ability to replay sessions has been especially valuable for understanding UX issues and refining the user journey. Overall, it’s helped us make more informed product decisions and build a better experience based on real user behavior.

Very easy to set up Session Replay

Very easy to set up Session Replay. It generally just works, autofilling the session key in documentation was a nice touch. Pricing seemed fair. Overall a great experience.

Seems like filtering Replays is not as easy as it could be since the UI is cramped as a left sidebar The other concern is very niche: There was slowness with Angular 8 but I found a workaround for it

When a user complains about a bug but was hard to reproduce (or actually their own fault) it is super helpful to see what they clicked to lead into that bug.

Great tool, great company

I fell in love with PostHog (the tool AND the company) on one of my personal side projects. As technology leader responsible for Architecture and Engineering, I am now rolling this out into my enterprise globally. I love things that have been built well, with love. It is very friendly for developers (good documentation), but also for product management. PostHog enables us to track performance and UX much better than we have been able to do through other tools. Communication with team has been good (as far as I needed it) and I've been showing their Handbook and Careers site around internally as inspiration.

Nothing signification - it is a product that is continuously evolving so we'll jus t Few smaller items: - Would love to have access to more of the tracked/consumed data - the PostHog data that is made available in the SQL editor is still limited. Right now, we are still using Azure Application Insights in addition - On Session Replay, would be nice to be able to filter out console messages. Already implemented filter on events, but I find that the logs (which we use quite a bit) to be too polluted. - On Session Replay, the search box on network requests doesn't seem to work well. - We find that not all events are properly tracked (e.g., on Session Replay, the network traffic). This might be due to the client? - Being a client-side tool, we still need to correlate manually to server-side logs. There are some options around data pipelines, but this is not yet usable in our setup. From vision: would be interesting how far they will take things like feature flags / experiments. Can do a lot more there to for instance compete with LaunchDarkly
