ZITADEL is a "Cloud Native Identity and Access Management" solution built for the cloud era. ZITADEL uses a modern software stack consisting of Golang, Angular and CockroachDB as sole storage and follows an event sourced pattern.

We built ZITADEL not only with the vision of becoming a great open source project but also as a superb platform to support developers building their applications, without need to handle secure user login and account management themselves.

How Does It Work

We built ZITADEL around the idea that the IAM should be easy to deploy and scale. That's why we tried to reduce external systems as much as possible. For example, ZITADEL is event sourced but it does not rely on a pub/sub system to function. Instead we built all the functionality right into one binary. ZITADEL only needs Kubernetes for orchestration and CockroachDB as storage.
