Live already hosted website wanting to add CMS

Hello. I have a website that is already hosted (not on Netlify) and I would like to use netlify-cms so my client can update a JSON file. I use as a place for my client to approve changes before i move the change to the hosted site. Is it possible to have my own domain and hosting elsewhere than netlify for production and be able to use netlify-cms?

Netlify CMS is now Decap CMS (see: [Support Guide] Understanding how DecapCMS (formerly NetlifyCMS) connects to your content on Netlify).

As for using Decap CMS without Netlify see the link in this post that may still hold relevance

Or check out the Decap CMS community


Thank you very much. I appreciate it.
