Where each one falls short

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

ESLint

Slow performance on large codebases compared to newer tools like Oxlint and Biome
Complexity in configuration from scratch, particularly for TypeScript support
Limited built-in TypeScript support, requiring separate parsers and coordination with new TypeScript features

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.
