Low-Code Platform for Java Developers.
Write just the domain classes in plain Java. Get a web application ready for production.
"I think OpenXava is an extraordinary tool, it makes reality a fantasy, that is MDD and at the same time works like a RAD, all this using Java."
"I've been developing software for close to 40 years and I am very impressed with OpenXava, not only with the ease in which I have rapidly developed a functional app, but with the extensive customizations that can be applied to achieve more complex behavior and desired look."
"I have worked before on Low-Code platforms like Mendix, Pega, OutSystems, etc. It seems easier to work without code only drag and drop and set properties, but still it is easier to work with OpenXava."
"The real catch about our experience while developing with OpenXava was the speed of development without compromising the quality."
"I must say: my compliments! ... I have actually quite a lot of experience in UI automation. So it takes a lot to impress me. And I am impressed."
"I've been able to put together more functionality in my initial 6 days of starting to learn OpenXava (and I know nothing about Java itself - yet) than I was able to accomplish in several weeks of either RoR or Laravel, and I know a bit of Ruby and PHP."
"We built a customizable and scalable ERP with OpenXava that rivals SAP. In fact, we even turned it into a hub for connecting ecommerce platforms. The implementations have been successful, and companies are satisfied thanks to its high stability and excellent performance — even with clients who have years of data and large volumes."
"I have been looking for a logical, understandable, simple approach to web tools for years now and OpenXava is the first thing I have found that fits that bill.A0Most tools like VisualStudio Web App are so extremely confusing and so many moving part that the learning curve is insurmountable."
"Openxava is brilliant. I used Wavemaker as a UI before, and that was really hard work."
"OpenXava for me is an exceptional tool, saving us time, made it standard interfaces, imposed a criterion of unique development in the organization."
High productivity
You only write the code for your data structure and business logic with Java. You do not write HTML, JavaScript, CSS, SQL, etc. The user interface and the database logic are automatically provided.
Short learning curve
If you know basic Java and JPA you're already an OpenXava developer, you don't need any more to create complete applications. The OpenXava bundle is prepared for a rapid startup.
Full-featured applications
Modern web Single-Page Applications (SPA). List mode with paging, ordering, filtering, adding / removing / moving columns, PDF reports, export/import to Excel, cards format, charts, etc. Detail mode with tabs, frames, dialogs, editors for references and collections, responsive layout, maps, discussion threads, photo gallery, file upload, dashboards, etc.
Flexibility
Flexible enough to solve any case you'll face developing a business application. For the user interface OpenXava has a bunch of annotations to define the layout of the view in a high abstraction level, this is enough for most cases. For the behavior it has a controller framework to define your own behavior for a certain part of the application, or even for overwriting the standard behavior of the whole application. Moreover, you can modify the way any part of the user interface is generated by defining your own editors for certain types or properties. Finally, you can program by hand the user interface of any module of your application using JSP, HTML or JavaScript.
Mobile user interface
In addition to the classic web user interface for desktop you can get a mobile user interface for your application from the same code.
Hot code reloading
Modify your Java code, JPA entities, configuration files, i18n messages, etc., and see the changes instantly without restarting the application. Just like paid external tools such as JRebel, OpenXava offers hot code reloading natively and for free, fully integrated into its framework. This eliminates the need for additional solutions and speeds up the development cycle, allowing fast iterations on business logic, user interfaces, or configurations while the application is running. Ideal for maintaining an agile workflow and saving many hours of waiting every day.
Use your favorite platform
Browsers: Chrome, Firefox, Edge and Safari. Databases: Any supported by Hibernate, that is Oracle, DB2, AS/400, Informix, PostgreSQL, MySQL, MS SQL Server and practically all relational databases. Operating systems: Any with Java 8 (or better) support, that is Windows, Linux, Mac, Unix, AS/400, z/OS, etc. Application servers: Any with support for Servlets 3.1 (or better), including Tomcat, JBoss, WebSphere, Glassfish, WebLogic, etc.
Security
OpenXava complies with OWASP Top Ten, which means it meets the highest security standards for web applications. In fact, OpenXava passes the OWASP ZAP web security test 100%, without any critical, medium, or low level alerts. In addition, we frequently release versions where we fix security bugs and update dependencies to avoid using vulnerable third-party libraries.
First class IBM i (AS/400) support
The first production applications developed with OpenXava were for AS/400, using the AS/400 as the database with the application server in Linux or Windows, or even running the OpenXava applications inside the AS/400 (using WebSphere). In all cases the OpenXava applications used the tables designed by the RPG programmers as is, so the RPG programs still could work against the same data. Currently, many public administrations and banks around the world use OpenXava applications against AS/400 in production. It means that OpenXava is optimized to work nicely against the AS/400, moreover the team behind OpenXava has the know-how to face mapping AS/400 databases with Java technology, not so easy because RPG programmers do not use foreign keys, nulls, they use overlapped fields to chain different tables, fixed-length fields, and many other non-relational style practiques.
Open source
LGPL license that allows you to develop commercial applications without paying any fees.
Multilingual
The standard labels and messages included in OpenXava are in English, Spanish, German, French, Chinese, Russian, Japanese, Portuguese, Catalan, Indonesian, Italian, Polish, Serbian and Swedish. Moreover, it's pretty easy to add a new language.

Quality support
Free support in community forums, though they have thousands of threads all questions are answered. Moreover, there is professional support available.
Based on Java standards
Thus you can migrate your current Java code easily to OpenXava, and vice versa. You can use any Java tool for OpenXava. Your Java developers are already OpenXava developers. OpenXava projects are Maven-based. You can use IntelliJ, NetBeans, Eclipse or Visual Studio Code as IDE. OpenXava works nicely with Java 8, 11, 17 and 21. OpenXava is based on Java Persistence API (JPA), Dependency Injection for Java and Bean Validation standards. OpenXava supports: JSR-338, JSR-317, JSR-303, JSR-330, JSR-220, JSR-153, JSR-311, JSR-339 and JSR-370.
Integration
Many developers have integrated their OpenXava applications with other enterprise technologies and tools such as Talend, Bonita Open Solution, Ehcache, Spring Framework, Spring Security, Spring Scheluding, Quartz, Groovy, IntelliJ, Grafana, Pentaho, Docker, etc.
20 Years of uninterrupted evolution
We release around 10 versions per year: 2 minor (with new features without breaking compatibility) and the rest maintenance (bug fixes and security patches). Every few years, we launch a new major version to stay at the forefront. We're currently on version 7. All this without pause from 2005 to 2025.
