Where each one falls short

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

Istio

  • Licensed under Apache License 2.0 per the project's GitHub repository (istio/istio LICENSE); as a CNCF graduated project it has no paid tier or vendor price to compare
  • Layer 7 features require deploying the Envoy service proxy alongside the lighter zero-trust tunnel option, per istio.io, so full traffic management capability is not available from the lightweight mode alone

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
