We installed PostHog on documentation.ai through Google Tag Manager, and autocapture started recording clicks and pageviews straight away. We didn't have to tag anything first. What we use most is how it joins anonymous visits to the person who later signs in, so we can follow someone from a blog post through to the product. The capture() API is simple. We send all our custom events (CTA clicks, demo bookings, pricing toggles, video plays, chat opens) through one helper. Adding a data-attr attribute to an element gives its autocaptured clicks a readable name without writing any code.

I used PostHog from about 2021 to 2023 for analytics on client online stores, and it was fine and did the job back then. We're now in their startup programme and coming back to it for our own products, since we have a lot launching.

I like how easy it is to use with the MCP or their agent functionality. Session Replay is a game changer.
