As you already know, WordPress 5.0 is due for release on November, 19th, 2018. The new block-based Gutenberg editor and the Twenty Nineteen theme, which is fully based on Gutenberg, are just around the corner – they are planned to be included into the major release.
However, as Allan Cole stated recently, Twenty Nineteen remains a work in progress and it might not be ready to be rolled out along with WordPress 5.0.
We were eager to see it in the wild but failed to find a Twenty Nineteen demo. Though there are quite illustrative Twenty Nineteen theme mockups and InVision prototypes, unfortunately, we can’t so far get the feeling of how the theme operates in real time.
So why not run it ourselves? This idea brought the WordPress 2019 theme demo to life and it is now accessible to everyone for preview purposes.
