 Cozystack comes with a catalog of **managed applications** (services) that can be deployed on the platform with minimal effort.
-These include relational databases (PostgreSQL, MySQL/MariaDB), NoSQL/queues (Redis, NATS, Kafka, RabbitMQ), HTTP cache, load balancer, and others.

 They are created with the same user workflow and are managed with Helm and Flux, just as other applications.
