I&#x27;m not sure I would consider it on the rise or a recent trend, considering we had a all sorts of these things over the past 6-7 years already (and more, if you include other JVM languages in the mix).<p>It sure is nice to see a bit of competition though. But I&#x27;m a bit afraid of too much fragmentation and proliferation, when sometimes fixing or improving good frameworks might be time better spent. It was (and still is) a bit annoying when every week brings about a dozen new web frameworks, a new UI toolkit, a new stack acronym, etc...<p>Oh well... I guess you can&#x27;t really tell what&#x27;s time well spent, and you can&#x27;t really product how frameworks will compete and improve evolutionarily.
