1. PostHog
Best for autocapture plus flags and replay in one tool
What it does better than Heap
PostHog offers autocapture like Heap but bundles product analytics, session replay, feature flags, experiments, and surveys into a single open-source platform. You can self-host for full data ownership, its pricing is transparent and usage-based, and the free tier is generous. That combination replaces several tools at once.
Where Heap still wins
Heap's autocapture data model and governance tooling are more mature, and its UI is more approachable for non-technical analysts.
Best for: Engineering-led teams that want autocapture plus a full product stack with transparent pricing.
