What running it takes

ZITADEL binary/container

Hover or focus an icon for its name. Dashed means not established; struck through means no; grouped icons are alternatives.

Current docs require PostgreSQL; no historical CockroachDB dependency inferred. Container stable tag is production release. Kubernetes/Helm instructions are manual deployment, not browser one-click. Infrastructure and staff time are not priced here; this page does not compare total cost.
