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.

Strapi

  • Cloud pricing is per project, not per account, so a second project doubles the bill
  • Starter at $35 a month allows 100,000 API requests, and overage is $1.50 per 25,000
  • Extra bandwidth is $30 per 100 GB and extra asset storage $0.60 per GB
  • Backups start at the Pro plan, weekly, and only become daily at Business
  • An uptime SLA is Business only, at $450 a month per project
  • Additional environments cost $60 a month on Pro and $300 a month on Business
