An open source Java RAD framework for enterprise web applications

As you may know, Microsoft Lightswitch was (and I say WAS because Microsoft killed it) a language for LOB applications-oriented companies, allowing you to develop applications very simple and in record time.

After months and months of searching for an alternative, I decided to try Jmix. At first, like any language, it seemed a bit laborious to learn. As I progressed, I could see the examples of code, sample projects, and other materials which helped to learn JAVA, and also that specifically applied to LOB applications, the area which I think we all are most interested in.

I could make two applications for internal use of our company in record time, and now we are developing a billing application. I can tell you that in two weeks we had an application that many micro companies could use to make their bills.The reason for making this application is to learn and to migrate the applications we have in Lightswitch to Jmix, especially as now it has Multi Database support.

I want to thank for the work done by the entire team of Jmix and send a big hug from Spain and encouragement to make this project a success.

Like all platforms there is a bit of a learning curve, but once you get the general hang of it you can become very productive, quickly.

I'm quite impressed how well their entity designer updates the database with no drama whatsoever. I also experimented with .NET Core EF and migrations recently and very quickly found myself in a position where the migrations stopped working and I spent a couple of hours trying to reverse migrations and get the code and database back in sync. This may of course be due to my lack of experience with Core EF code migration, but still - I never had that situation with CUBA.

Jmix also provides support for Polymer out of the box for SPA type mobile apps, although I've only played with one of their samples to see how it works. I assume you can write an Angular app against the REST services as well if you wish.

Anyway, highly recommended for LS users looking for an alternative.
