Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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
Envoy
- Licensed under Apache License 2.0 per the project's GitHub repository (envoyproxy/envoy LICENSE); as a CNCF graduated project it has no paid tier or vendor price to compare
- Envoy is a proxy that runs alongside each application instance, per envoyproxy.io, requiring a sidecar or edge deployment model rather than a single centralized install
