Automattic announced that they have launched Gutenberg Block Kit on Glitch.
We are hoping this experiment will help anyone with an idea for a Gutenberg block to quickly prototype and build their block, company stated in the official press release.
When you click the Remix button on the Gutenberg Block Kit project, you get a full JavaScript development environment right in your browser. Nothing to install, just edit and see your changes in the live preview, they have explained.
