Stytch

About Stytch

Stytch is an identity platform providing authentication, authorization, and security through a single integration for web and mobile applications. It supports enterprise-grade authentication methods including passkeys, breach-resistant passwords, and SAML/OIDC-based SSO, along with multi-factor authentication, role-based access control, and JIT provisioning. The platform offers turnkey multi-tenancy with per-organization auth policies, SCIM support, and an embeddable admin portal that lets customers self-serve SSO and organization settings without involving the engineering team.

The platform also addresses machine-to-machine authentication and AI agent identity, including authorization and consent management for AI agents and tooling built on MCP (Model Context Protocol). It includes bot and fraud protection with device fingerprinting, invisible CAPTCHA, intelligent rate limiting, and stated 99.99% bot detection accuracy, along with SMS and email provider failover for delivery of login and authentication messages.

Stytch provides pre-built web and mobile UI components, headless SDKs, and backend APIs, allowing developers to control how much of the login experience they build versus offload. It is aimed at engineering teams building consumer or B2B applications that need to scale authentication from initial users to large enterprise customers, and includes example apps and quickstarts for Next.js and React in both B2B and consumer contexts.
