Where each one falls short

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

Backendless

  • Free tier limited to 50 API requests per minute and 20 database tables
  • Smaller community and integration ecosystem compared to Firebase or AWS
  • Customization beyond codeless tools requires developer expertise
  • Limited documentation for advanced use cases and edge cases

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.
