The most powerful alternative to Firebase
Spend less time on auth
Easy to maintain authentication and security, maximum flexibility with your backend stack, and more hands-on support than Google can provide.
AuthN and AuthZ infrastructure with unparalleled flexibility
Auth how you want it, with pre-built UI, headless frontend SDKs, and backend APIs and SDKs
Simplify your codebase with tailored data models for consumer and B2B auth, freeing you from complex middleware
Scale with ease. MFA, SSO, RBAC, and SCIM—your entire auth roadmap, just an API call away
Manage users, organizations, and auth settings directly in your dashboard with an embeddable admin portal
Lower friction UX. Higher-converting signups
Faster OAuth integration
Stytch normalizes data models and nomenclature across providers, making OAuth easy and intuitive to integrate.
Account de-duplication
If a user signs up with their email address and later signs in via social login, Stytch automatically links and safely de-duplicates the accounts.
Simplified org discovery and login flow
With opt-in just-in-time provisioning by validated email domain, self serve organization creation and surfacing of pending invites.
No building admin portals from scratch
Unlike Firebase, which forces you to build your own admin portal manually with their Admin SDK endpoints, Stytch provides a SDK and components to embed an admin portal directly into your application. This interface empowers admins to configure and manage enterprise auth features like SSO within your platform without needing to build it yourself.
Leading fraud and abuse protection, built-in
The world's most powerful fingerprint
Device intelligence built on a powerful combination of deterministic signals and supervised machine learning.
Hardened against the most sophisticated attackers.
Immutable and resistant to evasion or reverse engineering, all while preserving user privacy.
What engineering teams are saying
Short, precise docs make all the difference for a great integration experience. Stytch’s docs were a breeze, and their illustrations and code examples helped a lot. It took us only four days to switch from Firebase to Stytch, and we created a new front end for the integration.
