About Jmix

Jmix is an open-source Java platform for enterprise software development with governed AI integration.

It extends Vaadin and Spring Boot with a data-centric architecture, built-in role-based security, and visual development tools, enabling Java teams to design, build, and scale enterprise web applications without rebuilding backend infrastructure from scratch.

AI in Jmix is integrated into the development workflow and operates on your domain model, helping generate Vaadin views, manage data interactions, and accelerate implementation while preserving architectural integrity. This approach ensures predictable development, maintainable code, and long-term system evolution without vendor lock-in or runtime fees.

Key features
for Vaadin
developers:

AI-assisted Vaadin UI development Use AI to generate and adapt Vaadin views and data bindings based on your domain model. Jmix AI Assistant understands Jmix and Vaadin architecture, producing code aligned with your application structure.
Declarative XML Layouts Jmix introduces a declarative approach to building Vaadin views. Use XML descriptors to define the layout and Java code to implement the logic.
Data-aware UI Components Extended Vaadin components can bind directly to entities for displaying, editing, filtering, and validating data. Custom Jmix components, such as the Generic Filter, make it easy to integrate business functionality into your views.
Entity-Centric Architecture Jmix uses entities as the central building blocks of the application. The same entity model is used across persistence, UI data binding, security rules, and business logic, reducing boilerplate and keeping the architecture consistent.
Security Out of the Box Jmix provides built-in security for your application. Access rules defined for entities and their attributes are automatically applied to UI components bound to that data. If a user does not have permission to view a field, the corresponding UI component will not be displayed.
Add-ons for Enterprise Features Jmix offers ready-made modules for common tasks, including report generation, business process management (BPM), audit, and more - all available through the marketplace.
Visual Development with Jmix Studio Jmix Studio is a visual development environment integrated into IntelliJ IDEA. It provides tools for designing the data model, generating Vaadin UI, managing database migrations, and configuring application features.
CRUD View Generation Jmix Studio can generate CRUD views for entities based on their metadata. These generated views serve as a starting point and can be fully customized using standard Vaadin development.
Hot Deploy Hot Deploy allows you to apply project changes to the running application instantly, without restarting the application server. Update the code and see the results immediately.
Native Vaadin Development Developers can use standard Vaadin components, community add-ons, and commercial Vaadin components without restrictions, because a Jmix application is a Vaadin application.

Enterprise-grade Security for Vaadin Applications

Vaadin works with Spring Security for authentication and route control, while Jmix adds enterprise-grade data-level security.
Rules are defined once and automatically enforced across the UI, data, and business logic.
