    From the README

    Ory Kratos is the developer-friendly, security-hardened and battle-tested Identity, User Management and Authentication system for the Cloud. Finally, it is no longer necessary to implement User Login for the umpteenth time!

    The Ory Network is the fastest, most secure and worry-free way to use Ory's Services. Ory Identities is powered by the Ory Kratos open source identity server, and it's fully API-compatible.

    The Ory Network provides the infrastructure for modern end-to-end security:

    It's fully managed, highly available, developer & compliance-friendly!
