FusionAuth
FusionAuth is the authentication and authorization platform engineered for developers who demand flexibility and control. Built from the ground up to integrate with any stack, every feature — from user registration to MFA and SSO — is exposed via a modern, well-documented API.
Support for every major identity protocol is included out of the box: OIDC, SAML, OAuth2, JWT, passwordless login, social sign-on, and more. Whether you’re building a greenfield app or retrofitting auth into a legacy system, FusionAuth adapts to your use case — not the other way around.
Need compliance? FusionAuth helps you meet GDPR, HIPAA, and COPPA standards quickly and reliably.
Deploy it your way: install on Linux, Windows, macOS, Docker, or Kubernetes — or go with FusionAuth Cloud, our managed SaaS hosting. No black boxes. No vendor lock-in. Just powerful, customizable auth that works the way you do.

Frontegg
Frontegg is a modern Customer Identity and Access Management (CIAM) platform purpose-built for SaaS applications. It gives developers a robust, low-code toolkit to implement advanced identity features like multi-factor authentication (MFA), single sign-on (SSO), passwordless login, and role-based access control (RBAC) without spending weeks wiring up custom flows.
Designed with developers in mind, Frontegg supports rapid integration via SDKs and APIs for Node.js, React, Python, and more. It includes built-in support for OpenID Connect, SAML, OAuth2, and Webhooks, and ships with pre-configured components for login, signup, user management, and organization hierarchies. Whether you're building multi-tenant apps, complex subscription logic, or entitlement enforcement, Frontegg scales with you.
Beyond the initial integration, Frontegg offloads identity maintenance from engineering by enabling non-technical teams to manage identity-related tasks through a secure admin portal. Product, Infosec, and Customer Success teams can enforce security policies, manage users, configure auth flows, and respond to customer needs without dev involvement.
Security teams can monitor and enforce identity compliance standards through real-time dashboards and built-in audit trails. Frontegg also ensures continuous updates to identity protocols, so developers don't have to worry about chasing evolving standards.
Frontegg reduces developer toil, shortens go-to-market timelines, and keeps engineering focused on high-impact product work. All while maintaining the security, scalability, and flexibility required by modern SaaS platforms.
