+### Web Frontend (VulnApp)
+
+[VulnApp](https://github.com/CrowdStrike/vulnapp) wraps this detection container in a Go web application, giving you a graphical, browser-based way to trigger detections instead of the TUI. It ships deployment manifests for both generic Kubernetes and OpenShift. See the [vulnapp project](https://github.com/CrowdStrike/vulnapp) for setup and deployment instructions.
