Where each one falls short

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

Parse Server

  • Deployment complexity and scaling challenges require operational expertise
  • Requires database management skills for MongoDB or PostgreSQL administration
  • Smaller community and ecosystem compared to Firebase or cloud alternatives
  • Query depth bypass vulnerability allowing denial-of-service attacks via complex REST/GraphQL queries
  • Stored XSS vulnerability through SVG file uploads requires patching

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.
