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; Transmit Security pricing is not published, so it cannot be compared early against competitors that post per monthly active user rates, and the eventual quote often mixes per-user and per-transaction units.

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

Transmit Security

  • Pricing is not published, so it cannot be compared early against competitors that post per monthly active user rates, and the eventual quote often mixes per-user and per-transaction units.
  • Migrating a live consumer identity base is a high risk project, and credential migration constraints mean some users must re-register, which shows up as measurable churn.
  • The vendor is smaller than the identity incumbents, so the partner and systems integrator pool is thinner and staffing a large programme is harder.
  • Workforce identity is not the focus, so an organisation wanting one vendor for employees and customers will still run two platforms.
  • The fraud detection value depends on traffic volume feeding the models, so a smaller deployment gets less benefit from exactly the capability that justified choosing it over a plain identity provider.

No. The services are composable, so detection and response or verification can be adopted alongside an existing provider such as Okta or Entra ID.
