+ Auto-capture tracks every click, pageview, and form interaction without manual instrumentation

+ Retroactive analytics — ask questions about past behavior without needing to set up tracking first

- Paid plan pricing is opaque — requires contacting sales

“Heap's auto-capture is a game-changer. Our PM asked 'how many users clicked the pricing toggle last quarter?' and we had the answer instantly — without ever setting up that event. That's impossible with other tools.”
