Where each one falls short

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

Rust

  • Compile times significantly longer than languages like Go or C
  • Smaller ecosystem of libraries and frameworks compared to Python or JavaScript
  • Community still smaller than mainstream languages, reducing available third-party resources

Stytch

  • Free tier limited to 10,000 monthly active users; scaling beyond this requires custom pricing negotiation
  • Fraud prevention capabilities billed at $0.005 per fingerprint for usage exceeding 10,000 free checks
  • Additional SSO or SCIM connections beyond the 5 included in free tier cost $125 each
  • Brand customisation and email removal require one-time payment of $99
  • HIPAA and advanced fraud protection only available in Enterprise tier
  • No native UI builder; requires custom frontend development for fully-branded auth flows
