Stytch
Stytch gives developers one API for login, authorization, and fraud checks in B2B and consumer apps. You add passkeys, SSO, SCIM, MFA, and machine-to-machine tokens without stitching Auth0-style add-ons to a separate risk vendor.
Where many auth platforms gate enterprise features behind sales calls, Stytch includes SSO, RBAC, and multi-tenancy in its pay-as-you-go tier with 10,000 monthly active users included. It also ships an embeddable admin portal so customers configure SAML and SCIM themselves.
Backend engineers, platform teams, and AI product builders use Stytch after Twilio acquired it to cover human users and agent identities in the same stack.
