Building or modernizing a Java enterprise web app has always been a long process, historically. Not even remotely quick.

That's the main goal of Jmix is to make the process quick without losing flexibility - with the open-source RAD platform enabling fast development of business applications.

Critically, it has very minimal impact on your server's performance, with most of the profiling work done separately - so it needs no server changes, agents or separate services.

Simply put, a single Java or Kotlin developer can now quickly implement an entire modular feature, from DB schema, data model, fine-grained access control, business logic, BPM, all the way to the UI.

Jmix supports both developer experiences – visual tools and coding, and a host of super useful plugins as well:

Slow MySQL query performance is all too common. Of course it is. A good way to go is, naturally, a dedicated profiler that actually understands the ins and outs of MySQL.

The Jet Profiler was built for MySQL only, so it can do things like real-time query performance, focus on most used tables or most frequent queries, quickly identify performance issues and basically help you optimize your queries.

Critically, it has very minimal impact on your server's performance, with most of the profiling work done separately - so it needs no server changes, agents or separate services.

Basically, you install the desktop application, connect to your MySQL server, hit the record button, and you'll have results within minutes:
