Where each one falls short

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

Ory

Production and Growth plans are billed annually ($770/year and $9,350/year), which is a larger upfront commitment than monthly-only competitors.
SAML SSO and multi-region deployments are reserved for the custom-priced Enterprise tier.
Usage-based pricing across aDAU, M2M tokens, and permission checks makes cost estimation more complex than flat per-MAU billing.

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.
