SmallRye Config

SmallRye Config is a library that provides a way to configure applications, frameworks and containers. It is used in applications servers like WildFly and Open Liberty, or frameworks like Quarkus. It can also be used completely standalone in any Java application, which makes it a very flexible library.

It follows the MicroProfile Config specification to provide the initial config foundations and expands with it own concepts to cover a wide range of use cases observed in the configuration space.
