Where each one falls short

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

Gravitee

  • The entry paid API management tier is $2,500 a month and includes a single production gateway
  • Event management is priced separately, starting at $1,250 a month for the Comet tier
  • Tiers are gated on gateway and broker counts, so scaling horizontally means moving tier rather than paying incrementally
  • Data logging masking and other enterprise features are withheld from the lowest paid tier
  • 24/7 support requires the top Universe tier

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
