The server waits. Keycloak stands ready, but the test data is empty. You need synthetic data fast—accurate, realistic, and safe for development.
Keycloak synthetic data generation solves this by creating users, roles, and realms without touching production. It lets you validate authentication flows, stress-test token issuance, and benchmark API performance with zero risk to sensitive information.
Synthetic data for Keycloak must meet several requirements. It must replicate the structure of production data, follow the same schema constraints, and maintain referential logic. Generating it requires scripts or specialized tools that can hit the Keycloak Admin REST API, create entities in bulk, and configure role mappings so your authorization checks are realistic.
One method is direct API automation. Using curl or HTTP clients, you can create hundreds or thousands of test users, assign them roles, and seed custom attributes. This approach works well for CI/CD pipelines, where ephemeral Keycloak instances spin up for integration tests. Another method is using synthetic data platforms with built-in Keycloak connectors. These can read your existing configuration, clone it, and fill it with fake identities that match your schema exactly.
