Where each one falls short

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

Auth0

  • Free tier limited to 25,000 monthly active users, requiring upgrade for growth beyond that
  • Advanced features like MFA and RBAC only available on paid Essentials tier and above
  • Ownership by Okta introduces risk that independent product roadmap may change

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.
