The short version

  • Only Stytch has a free tier, so it costs nothing to try first.
  • Each has a real cost: Stytch free tier limited to 10,000 monthly active users; scaling beyond this requires custom pricing negotiation; ThetaRay unsupervised models are harder to justify to an examiner than explicit rules, and some regulators still expect documented threshold logic, which can force you to run both systems.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

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

ThetaRay

  • Unsupervised models are harder to justify to an examiner than explicit rules, and some regulators still expect documented threshold logic, which can force you to run both systems.
  • The alert reduction claim depends heavily on your data, so a parallel run is essential and adds months and cost before you can decommission the incumbent.
  • Coverage is strongest in cross-border and correspondent flows; institutions whose risk is domestic retail fraud will find the fit weaker than a general-purpose monitoring platform.
  • It is a smaller vendor than the incumbents, so integration connectors into legacy core banking systems are often bespoke work rather than a supported adapter.
  • Model retraining and tuning are vendor-led, which means changing detection behaviour is a support conversation rather than something your own analysts can do that afternoon.
