websites and application development

HI there guys I have a strange question regarding websites and application development. I seen websites are starting to dwindle a but online but the space for online application development is massive. There are many developers around the world that used to do websites now doing apps. Some of them i know personally as my competition and while i would be very surprised they learnt how to develop large scale application in a few months im somewhat sketipcal.

My question is thus are there frameworks akin to laravel or even drag and drop type systems for apps out there? that are open source.

I know the quality of such apps may not be the best, but its a starting point whilst learning the real deal or maybe im even wrong about that.

Web application development is the creation of application programs that reside on remote servers and are delivered to the user's device over the Internet. ... Front-end development for web applications is accomplished through client-side programming. Client refers to a computer application such as a web browser.
