Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Heap

  • No built-in A/B testing or feature flags; requires integration with separate tools for experimentation
  • Group analytics and advanced features require a sales conversation, not self-serve
  • Cloud-only deployment; no self-hosted option for data security or compliance requirements
  • Session replay lacks developer debugging tools compared to PostHog
  • Pricing for Growth and Pro plans requires direct sales contact; no transparency on how pricing scales

Statsig

  • Pro plan is limited to a single project, requiring Enterprise for multi-project support.
  • Overage pricing on the Pro plan can become costly for high-event-volume products.
  • Warehouse-native deployment and advanced access controls are gated behind custom Enterprise contracts.
  • Free tier session replay and analytics retention are capped, pushing active teams toward paid tiers quickly.
