Where each one falls short

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

Stainless

Starter and Pro plan prices are not published and require contacting the company.
The free plan caps APIs at 25 endpoints, which excludes larger production APIs.
Overage charges apply per SDK/endpoint/month once limits are exceeded, which can make costs unpredictable at scale.

Moesif

Free tier is aimed at hobbyists and small projects, limiting scale before paid usage-based pricing applies.
Usage-based pricing on the Growth tier can make costs less predictable at high event volumes.
Requires instrumenting APIs with SDKs, adding setup overhead compared to zero-config tools.
Focused specifically on API analytics rather than full API gateway or design functionality.
