RESTEasy is a JBoss / Red Hat project that provides various frameworks to help you build RESTful Web Services and RESTful Java applications. It is an implementation of the Jakarta RESTful Web Services, an Eclipse Foundation specification that provides a Java API for RESTful Web Services over the HTTP protocol.
Moreover, RESTEasy also implements the MicroProfile REST Client specification API.

RESTEasy can run in any Servlet container, but tighter integration with WildFly Application Server and Quarkus is also available to make the user experience nicer in those environments.
