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

Proton Mail

  • Free tier limited to 1 GB storage
  • Free tier limited to single email address

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.
