“Gutenberg” is the codename for the 2017 WordPress editor focus. The goal of this focus is to create a new post and page editing experience that makes it easy for anyone to create rich post layouts
Gutenberg is, in simplest terms, a replacement for the TinyMCE editor (aka the “default” WordPress editor). If you’ve ever used WordPress, you’ve almost certainly used TinyMCE.
Gutenberg uses “blocks” of content which can be arranged and customized to give users more control over how their posts and pages look. On the surface, it’s not unlike the editing experience of Wix, SquareSpace, and existing WordPress page-building plugins like Elementor.
Currently, Gutenberg has blocks that handle all of the features you’re used to in the WordPresss editor now: paragraphs, headings, lists, images, galleries, media embeds, etc. Plugin and theme authors can also create new blocks for different types of content, and some plugins are already “Gutenberg aware.”
Simply put, Gutenberg gives you more control over how your site looks than the current TinyMCE editor.
When Is Gutenberg Available?
As stated above, you can install Gutenberg as a plugin right now if you want to test it. Gutenberg is currently scheduled to be packaged as part of WordPress core starting with the 5.0 release. When is the 5.0 release? Well, we don’t know yet.
Why Not Use Gutenberg
At the time of this writing, there are some issues that could arise if you were to update your website to a version that includes Gutenberg instead of TinyMCE. Mainly, Gutenberg may break your editing experience if you are using a theme or any plugins which use custom fields to store and display content. It is up to each plugin and theme author to update their product to be compatible with Gutenberg. You could lose the ability to edit your content’s custom fields (because Gutenberg doesn’t use custom fields – it uses blocks).
How to Not Use Gutenberg
Install the Classic Editor plugin, which detects for the presence of Gutenberg on your site and circumvents it. Note: at the time of writing, this plugin is not ready for production so it would be better to make a note of it now and only install it if needed.
