The short version

  • Each has a real cost: Kubernetes complex initial setup and configuration with multiple interdependent components; PostHog the free tier covers 1M events, 5K web session recordings and 2.5K mobile recordings per month before usage-based billing starts
  • They diverge on capability: Kubernetes covers Container orchestration, PostHog covers Product analytics.

Where each one falls short

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

Kubernetes

  • Complex initial setup and configuration with multiple interdependent components
  • Significant resource requirements for both hardware infrastructure and specialized human expertise
  • Expensive specialized talent in Kubernetes domain; hiring costs prohibitive for many organizations
  • New security challenges around container isolation and network security requiring robust measures
  • Requires continuous maintenance and updates to stay current with releases and security patches

PostHog

  • The free tier covers 1M events, 5K web session recordings and 2.5K mobile recordings per month before usage-based billing starts
  • Accounts without a card on file are limited to 1 project; adding one raises it to 6
  • Data retention is 1 year until a card is added, which extends it to 7 years
  • Support is community-only until the account is on a paid plan
  • Error tracking is capped at 100K exceptions and surveys at 1500 responses per month on the free tier
