Simpla.io CMS for Webflow

Hi there, I have a scenario.

My clients wants new a website with CMS and it should be hosted on their on-prem server. So I can’t use Webflow CMS, I have to develop the front-end on Webflow and export the code to develop CMS elsewhere. Can I use Simpla.io? Or any other suggestions?

Maybe you can have a look at this:
