Bundled	Executable WAR	❌	☑️	✅	✅

API Server

The API Server contains an embedded Jetty server and all server-side functionality, but excludes the frontend user interface. This variant is new as of Dependency-Track v4.0.

Frontend

The Frontend is the user interface that is accessible in a web browser. The Frontend is a Single Page Application (SPA) that can be deployed independently of the Dependency-Track API Server. This variant is new as of Dependency-Track v3.8.

Bundled

The Bundled variant combines the API Server and the Frontend user interface. This variant was previously referred to as the executable war and was the preferred distribution from Dependency-Track v3.0 - v3.8. This variant is supported but deprecated and will be discontinued in a future release.

Traditional

The Traditional variant combines the API Server and the Frontend user interface and must be deployed to a Servlet container. This variant is not supported, deprecated, and will be discontinued in a future release.
