Amazon Cognito
Amazon Cognito lets you add user sign-up, sign-in, and access control to your web and mobile apps quickly and easily.

Keycloak
Keycloak is an open source identity and access management solution for modern Applications and Services. Add authentication to applications and secure services with minimum fuss.

Amazon Cognito and Keycloak are both in the business of keeping your digital identity in check, but they go about it in very different ways—like a meticulously organized robot versus an eccentric, slightly unpredictable inventor. Amazon Cognito is the robot: a fully managed service that exists in the sprawling, cloud-filled halls of AWS. It takes care of your user authentication, sign-ups, sign-ins and all the other things you didn’t know you needed until it suddenly reminded you. With its friendly support for social logins, multi-factor authentication and seamless connection to everything else in the AWS universe, Cognito is like the concierge at a very exclusive, very virtual hotel—if the hotel also handled your deepest secrets.

Keycloak, on the other hand, is the inventor tinkering away in the corner, open-source and self-hosted. It can live wherever you want it to—on-premises, in the cloud, or perhaps in the broom cupboard. It’s all about flexibility, offering a dazzling array of authentication protocols like OpenID Connect and SAML and it loves to federate users from different realms (as one does). Customization is Keycloak's middle name; it practically begs you to tweak, extend and mold it to your will, much like the inventor’s latest contraption that may or may not be a time machine.

The key difference? Amazon Cognito is the reliable but rigid butler, who’s excellent with AWS but not so keen on stepping outside. Keycloak, on the other hand, is the mad scientist—brilliantly flexible but requiring a bit more care, feeding and occasional fire-extinguishing. Both will manage your users, but one does it with corporate precision while the other does it with open-source flair and an occasional puff of smoke.
