Best For
HeapMarketing teams who want to track every button click without needing developers to write custom tracking code
PostHogEngineering-heavy startups wanting an open-source, all-in-one product analytics suite
Pros
Heap
The "auto-capture" feature is magical — it tracks every click/form submission automatically, meaning if you realize 6 months later you want to track a specific button, the data is already there retroactively
less reliant on developers
PostHog
Combines Mixpanel (analytics), Hotjar (recordings), and LaunchDarkly (feature flags) into one open-source tool
highly developer-friendly
generous free tier
Cons
Heap
Auto-capture can lead to a messy, cluttered data environment if not governed strictly
expensive at higher tiers
PostHog
Requires engineering to set up and self-host (if choosing the open-source route)
