I have put together a blog using Nift where you can modify the posts and add new posts using Netlify CMS, all without Nift being on Netlify’s build image yet.
The link to the blog is here and the admin portal is here. I am leaving registrations open for the next few days so that people can have a play, then I’m going to make it invite only so that I can add it as a template to the Nift website.
