What is Gutenberg?

Johannes Gutenberg was a European who invented the printed press, revolutionizing the publishing industry. Aiming for a similar transformation in the digital publishing industry, WordPress named its new editor after the inventor, Gutenberg.

In December 2018, the Gutenberg Editor was made public. It was released to the public as part of the WordPress 5.0 update. Gutenberg is a way for WordPress to keep up with the DIY trend, which is growing quickly. Since the project’s goal was to alter the process of producing and modifying WordPress posts radically, the term Gutenberg was initially given to the project while the editor was still developing.

The Block Editor is an alternate term for Gutenberg. This is because the editor revolves around the concept of blocks to build a website. Blocks are separated into categories such as embeddable blocks, media elements, formatting blocks, etc. You can also customize them to build a visually appealing and content-rich webpage.

  • Makes content creation easy for beginners.
  • Helps you see how your content will look on the front end.
  • No need for separate shortcodes to make creating content more accessible.
  • You will get more options and specialized blocks to customize content.
  • No need to install a page builder plugin separately.


  • Even though the goal is to make the interface easy to use, complex things may be harder to learn.
  • There will be a lot of problems with themes and plugins already in use, and it may even break some sites. However, this issue is getting better with each update.

What is Classic Editor?

Classic Editor is the old default editor of WordPress, which later got replaced by the Gutenberg editor. It is a simple WYSIWYG text editor in which content creation was not so easy.

For years, customers who wanted to avoid complicated formatting and designs have considered the Classic Editor ideal, and it makes sense when you think about it.

The uncomplicated text-based Classic Editor may be your best choice if all you want is a quick, easy way to arrange multimedia content.

But is that all there is to it? Let’s examine the Classic Editor’s main advantages and disadvantages.


  • Looks like a plain rich-text editor.
  • You can add HTML tags.
  • Formatting and content creation are easy.
  • Code tag for displaying code snippets.
  • Familiar design.


  • Not the best way to make complicated pages like landing pages.
  • For any complicated editing, you need to know HTML.
  • It needs extra plugins to add more features.
  • Slow performance.

The most significant drawback, though, is how it compares to Gutenberg’s built-in features. Finding a benefit of the Classic Editor that Gutenberg does not provide is difficult. Also, the Classic Editor lacks various tools that improve the quality of life and the content.
