Versions:
OpenWebStart 1.13.0, released by Karakun AG as the fourteenth iteration of the software, is a cross-platform deployment technology designed to keep Java Web Start applications executable after Oracle discontinued Web Start support with Java 11. Acting as a drop-in replacement for the abandoned Oracle implementation, the program parses JNLP (Java Network Launch Protocol) files, downloads the required resources, verifies digital signatures, and launches the specified Java Runtime Environment in a sandboxed or unrestricted security context depending on the application descriptor. Typical use cases include corporate environments that continue to rely on legacy ERP, CRM, or in-house rich-client tools originally distributed via Web Start, educational institutions that launch interactive courseware, and governmental agencies that access secure forms or data-entry clients without rewriting them for standalone installation. Administrators can centrally configure proxy settings, whitelist servers, pre-approve certificates, and enforce version-specific JRE provisioning through the OpenWebStart management console, ensuring that end-users receive a one-click launch experience comparable to the former Oracle workflow while remaining compatible with current Java 8, 11, 17, or 21 runtimes. The software is classified under the “Java & JVM” category of development utilities and is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
