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

Vercel

  • Usage-based pricing can spike unexpectedly during traffic surges or DDoS attacks
  • No spending limit controls or automatic shutoff mechanisms
  • Bandwidth costs ($0.15/GB) quickly accumulate for high-traffic applications
