AppJars are modular, production-ready building blocks for enterprise Java applications, built on Spring Boot and Vaadin. Each AppJar covers one functional area — users, permissions, configuration, translations, email, activity logging, reporting — and drops into your own application instead of being rebuilt from scratch.
Every AppJar can be used free of charge with limited functionality. A paid subscription unlocks the full feature set and includes every update released during the subscription period. Individual AppJars and the Full Bundle are in the catalog.
The AppJars themselves are a commercial product and their source lives in private repositories. What is public here is the issue tracker, the community forum, and — for every AppJar — a runnable demo, open source and yours to keep.

Every AppJar has a public demo repository: a runnable application with sample data and the AppJar's
features on display. Clone it, run mvn, click around. It runs with the AppJar in free mode, so you
can try it without a license.
Demos are open source, under Apache 2.0.

Free and paid users report bugs in the same tracker, under the same rules. Fixing defects is part of the product, not a paid service. The full explanation of every channel is in SUPPORT.md.
The AppJars themselves are closed-source, so there is nothing public to open a pull request against. Bug reports and feature requests for them go to AppJars/appjars — a reproducible report is the single most useful thing you can send us.
The demos are a different matter. They are open source, and we take issues and pull requests on them directly. If one does not build, the wiring is out of date, a README describes something the code does not do, or you know a cleaner way to wire an AppJar in, open it on that repository. Details in CONTRIBUTING.md.
Artifacts are published under the com.appjars group ID to the AppJars Maven repository at
https://maven.appjars.com. The repository declaration and the module coordinates for each AppJar
are in the getting started guides.
AppJars is developed by Flowing Code S.A. (Argentina), which owns all intellectual property in
the products, and distributed internationally by Flowing Code LLC (Florida, USA), the licensor
of record.
