StackMatch Editorial verdicts

Bylined · No vendor influence
PostHogBUY
The product analytics suite that ate three categories

PostHog has quietly become the default for product analytics, session replay, feature flags, and experiments in one tool. Each individual product is good enough, the bundle is undefeatable on price, and self-hosting is genuinely viable.

Choose PostHog if...

Engineering-led early-stage teams that want an all-in-one platform, or regulated/data-sovereign organizations that self-host.

Avoid PostHog if...

Non-technical teams (configuration is code-forward) or large enterprises that need mature SSO, governance, and dedicated support (Amplitude fits better).

Choose Heap if...

Product and growth teams that want product analytics without upfront event planning. Excellent when instrumentation is immature.

Avoid Heap if...

Teams already mature on Amplitude/Mixpanel with good event taxonomies — switching cost may not be worth it.
