Powerful
Configuration in WildFly is centralized, simple, and user-focused. The configuration file is organized by subsystems that you can easily comprehend and no internal server wiring is exposed. All management capabilities are exposed in a unified manner across many forms of access. These include a CLI, a web based administration console, a native Java API, an HTTP/JSON based REST API, and a JMX gateway. These options allow for custom automation using the tools and languages that best fit your needs.
Modular
WildFly does classloading right. It uses JBoss Modules to provide true application isolation, hiding server implementation classes from the application and only linking with JARs your application needs. Visibility rules have sensible defaults, yet can be customized. The dependency resolution algorithm means that classloading performance is not affected by the number of versions of libraries you have installed.
Lightweight
WildFly takes an aggressive approach to memory management. The base runtime services were developed to minimize heap allocation by using common cached indexed metadata over duplicate full parses, which reduces heap and object churn. The administration console is 100% stateless and purely client driven. It starts instantly and requires zero memory on the server. These optimizations combined enable WildFly to run with stock JVM settings and also on small devices while leaving more headroom for application data and supports higher scalability.
Standards Based
WildFly implements the latest in enterprise Java standards from Jakarta EE and Eclipse MicroProfile. These improve developer productivity by providing rich enterprise capabilities in easy to consume frameworks that eliminate boilerplate and reduce technical burden. This allows your team to focus on the core business needs of your application. By building your application on standards you retain the flexibility to migrate between various vendor solutions.
Latest News
In this demonstration, we are using the Gemini CLI to get started with WildFly using its MCP server. By pointing the Gemini CLI to a war file and asking high-level questions, we can provision a server, deploy the application, run the server, and access the WildFly web console.
Watch Video >The new Agent2Agent (A2A) Protocol establishes an open standard for universal interoperability, allowing AI agents built by different vendors or on separate frameworks to communicate and collaborate effectively. By providing a standardized method for exchanging information and coordinating actions, A2A empowers businesses to create a unified, multi-agent ecosystem that breaks down data silos and automates complex workflows across their entire enterprise.The specifications of this protocol are available online, and you can find SDKs for...

The following issues were resolved in 36.0.1: Bugs [WFLY-19970] - Jakarta MVC from Wildfly 34 built with Galleon on stability level preview cannot find custom template engines in an EAR [WFLY-20564] - Deploying postgresql-42.7.5.jar causes NPE when upgrading from wildfly 35→36 [WFLY-20617] - Deployment fails due to NullPointerException in ExpirationMetaData.getLastAccessTime() Component Upgrades...
Read More >WebAssembly (WASM) has emerged as a powerful technology for running high-performance code in various environments. In this article, we’ll explore how to expose WASM binaries as Model Context Protocol (MCP) tools in WildFly. With WildFly AI Feature Pack 0.5.0 we have introduced a new subsystem to expose WASM WebAssembly System Interface (WASI) binaries via CDI, and since we also support MCP tools declaration via CDI, just exposing those binaries as MCP tools was a...
