WildFly is a modular and lightweight application server designed for developers and companies aiming to build powerful applications. It features a centralized and user-friendly configuration system, organized by subsystems, ensuring ease of comprehension without exposing internal server wiring. Management capabilities are accessible through various interfaces, including a command line interface (CLI), a web-based console, and a REST API, allowing for automation with preferred tools and languages.

The application server utilizes JBoss Modules for application isolation, ensuring that only necessary JARs are linked to applications. This enhances classloading performance, regardless of the number of library versions installed. WildFly supports a wide range of users, from small businesses to enterprises, and integrates with numerous applications and services, catering to diverse organizational needs.
