Creating a SaaS... Looking for certain specification

Hello.
I actually have two very different Saas applications that I am trying to get off the ground.

  • I need a React JS front end that I can deploy in a Container and that can be hosted to any cloud provider (AWS, Azure, GCP, Digital Ocean, Heroku, etc).

  • I need to be able to access the code so that I can wire it up to my API backends. It would be nice if it supported webhooks.

  • I need to be able to customize to be used by two completely different (and not remotely similar) Saas Applications

  • I also need it to be relatively cheap.
    Is there anything on this site that is remotely like that?

Why do they call them “code scripts” on this page? And why are they all based off of PHP? PHP is an old technology that most modern web pages and SaaS applications have abandoned years ago.
The architecture of Uploading that to a web server along with your other HTML static assets is archaic. I was hoping for something more modern, that I can deploy in a container (for scalability). Anything like that?
