"I can't recall when I was so excited about a framework, specially for web development. I have been in the field since 1983 and I am hard to impress. With OpenXava I am impress!"
"This is like a dream come true, as I have been wanting something like that since the day I programmed my first user interface."
"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."
"Honestly, OpenXava has changed the way rapid Application Development should be. We are happy developers since then."
"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."
"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. Most 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."
"The real catch about our experience while developing with OpenXava was the speed of development without compromising the quality."
"OpenXava for me is an exceptional tool, saving us time, made it standard interfaces, imposed a criterion of unique development in the organization."
"Good tools with good support. Developer utopia!"
"I'm very excited. I have many flight hours as programmer and I didn't find something so good for a long time."
"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."
"Excellent framework. Easy implementation, pretty simple yet very powerful."
"Great for Rapid Development."
"I am using OpenXava and finding it wonderfully refreshing, as someone who needs to program in Java with no Java knowledge it is a wonderful tool so thanks!"
"This framework never ceases to surprise me, the best development framework you've never seen, without a doubt. Speechless."
"OpenXava is a high quality framework for Java. Very productive."

ZX-Ed: Open source database editor
ZX-Ed is a database editor and script generator for ZXDB. ZXDB is an open database containing historical information of software, hardware, magazines and books about ZX-Spectrum and related machines. It's currently the most widely used Sinclair related database, feeding several Spectrum websites, an open API at ZXInfo, and the mobile application Zx App that uses this API. It's also used as index reference by a dozen different websites and services. ZX-Ed is open source and available on GitHub. It was created by Einar Saukas using OpenXava.
When we asked Einar why he chose OpenXava he tells us:
"I needed a CRUD for an already existing, fairly complex database. However most existing tools and frameworks impose severe restrictions on the database structure they can handle, so they are not much viable in practice. After comparing several CRUD design solutions, I believe that OpenXava provides the best tradeoff between flexibility and productivity. You only need to generate and maintain entity code (that can match any database model), and everything else is optional (OpenXava provides an appropriate default behavior for everything else)."
