AppJars

What it does

Production-ready, drop-in modules for Java apps on Spring Boot and Vaadin. User management, audit logs, reporting, i18n, issue tracking, AI support and more. Each one is a complete feature you add with a dependency, UI included. Stop reinventing the infrastructure and focus on your business logic. Every module has a free mode you can use without a license, with source included and offline licensing.

Production-ready Java modules for Spring Boot and Vaadin. Add reporting, issue tracking, user management, AI support and more as Maven dependencies.

AppJars are enterprise-grade Java modules that plug into any Spring Boot and Vaadin app as Maven dependencies: a catalog that covers reporting, issue tracking, user management, AI support and more. Every AppJar ships the whole stack: JPA entities, DAOs, services and ready-made Vaadin views. Weeks of work become one dependency and a handful of properties. Native Maven dependencies for Spring Boot, JPA and Vaadin. Add the artifact to your pom.xml and Spring Boot auto-configuration wires the module at startup. No code generation, no manual wiring. Full source code included, for transparency and for debugging in your own IDE. Licenses are perpetual and validate offline, and one license file…from appjars.com
