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

Speakeasy

No self-serve pricing is published; every plan requires a sales conversation.
The product pivoted away from its original SDK-generation offering, so past documentation and customers built on that use case are no longer the focus.
Requires integration with an existing identity provider such as Okta or Entra ID to be useful, so it is not a standalone solution.
No published free tier or trial pricing was found.
