## What it is
RESTEasy is a Java framework implementing the Jakarta RESTful Web Services (JAX-RS) specification and the MicroProfile REST Client API for building RESTful web services and clients. It runs in any servlet container with tighter integrations for WildFly and Quarkus, and offers rich providers, caching, and async/reactive support.

## Use cases
- build RESTful web services in Java
- implement JAX-RS endpoints in a servlet container
- create REST clients with MicroProfile REST Client
- serve and consume JSON, XML, YAML, and multipart payloads
- embed a REST server in JUnit tests
- integrate REST endpoints with Spring Boot or CDI
- add HTTP caching and ETag support to REST APIs

## When to choose
- you need a spec-compliant Jakarta REST implementation on the JVM
- you deploy to WildFly, Quarkus, Tomcat, or other servlet containers
- you want broad provider support (JSON, XML, JAXB, multipart, GZIP) out of the box
- you need an embeddable server for testing REST resources

## When to avoid
- you are building non-JVM services
- you prefer a lightweight non-spec framework like Spring Web MVC or Micronaut
- you need gRPC-first or GraphQL APIs rather than REST
