What is AppJars?

AppJars is a low-code development platform for Java teams building business applications with Spring Boot and Vaadin. Instead of an opinionated platform or a proprietary IDE, AppJars gives you a catalog of production-ready modules (“AppJars”) that you add to your own project as regular Maven dependencies.

Each module covers a common enterprise need end to end: data model, persistence, business logic and a ready-to-use Vaadin UI. Available modules include User Manager, User Profile, Activity Log, Configuration Manager, I18N Manager, Dynamic Menu, Email Manager, Process Manager, Data Query, Issue Tracker and AI Support.

Key features:

  • Composable: use one module or combine many, with no lock-in to a framework or IDE
  • Idiomatic Vaadin and Spring Boot code that your team can read, extend and debug
  • Runs on your own infrastructure; nothing is cloud-hosted
  • Agent-ready: an MCP server (mcp.appjars.com) helps AI coding assistants build apps on AppJars
  • Project generator (craft.appjars.com) to bootstrap new applications in minutes
  • Freemium model: free perpetual use in limited form, a license key unlocks full features

Built and maintained by Flowing Code, a software company specialized in enterprise Java and Vaadin applications.
