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.

Run ZITADEL anywhere


You can run an automatically operated ZITADEL instance on a CNCF compliant Kubernetes cluster of your choice:


  • ZITADEL Cloud: is our shared cloud service hosted in Switzerland. Get started and try the free tier, including already unlimited users and all necessary security features.
  • ZITADEL Dedicated: We operate and support a dedicated instance of ZITADEL for you. Get in touch!

Usage Data

ZITADEL components send errors and usage data to CAOS Ltd., so that we are able to identify code improvement potential. If you don't want to send this data or don't have an internet connection, pass the global flag --disable-analytics when using zitadelctl. For disabling ingestion for already-running components, execute the takeoff command again with the --disable-analytics flag.

We try to distinguishing the environments from which events come from. As environment identifier, we enrich the events by the domain you have configured in zitadel.yml, as soon as it's available. When it's not available and you passed the --gitops flag, we defer the environment identifier from your git repository URL.

Besides from errors that don't clearly come from misconfiguration or cli misuage, we send an inital event when any binary is started. This is a " invoked" event along with the flags that are passed to it, except secret values of course.

We only ingest operational data. Your ZITADEL workload data from the IAM application itself is never sent anywhere unless you chose to integrate other systems yourself.
