Overview
Description

Authentik is an open-source authentication server that provides a comprehensive solution for identity and access management. It offers a wide range of features, including multi-factor authentication, single sign-on, and user management.

Frontegg is a customer identity and access management (CIAM) platform that secures the entry points into SaaS applications, describing itself as "the identity layer for every SaaS entry point." It provides a low-code approach to identity management so engineering teams can offload authentication, SSO, and multi-tenant user management instead of building it in-house. Beyond traditional CIAM, Frontegg also offers Agen.co, an enterprise-grade agentic layer that lets users interact with SaaS products safely through generative AI interfaces. The platform uses usage-based pricing tied to monthly active users, enterprise SSO/SCIM connections, and machine-to-machine token exchanges.
