Hi Product Hunt 👋 I'm Martín, from Flowing Code. We've spent years building enterprise Java apps for clients and maintaining 30+ open-source Vaadin add-ons, and we kept hitting the same wall: every project starts by rebuilding the same foundations before you get to the part that actually matters. AppJars is our answer. Production-ready, drop-in modules for Spring Boot and Vaadin apps: user management, audit logs, reporting, internationalization, issue tracking, AI support and more. Add a dependency, register a layout, and the feature is there, UI included. A few things we care about: - Every module has a free mode you can use without a license, even in production within some limits. - The source is included, so you can read and debug what runs in your app. - License validation runs fully offline, no phone-home. - Licenses are perpetual: you own the version you buy forever, and each purchase includes a year of updates and support. We built this over years, at our own pace, and today we finally get to share it. I'll be around all day to answer questions. What's the part of your enterprise apps you're most tired of rebuilding?
