Raw HTML is a powerful WordPress plugin designed for users who need to utilize raw HTML, CSS, and JavaScript in their posts without interference from WordPress's automatic formatting. This plugin allows users to wrap content in [raw]…[/raw] tags, ensuring that formatting such as smart quotes or automatic paragraph breaks do not alter their custom code. Additionally, it introduces new checkboxes in the Edit Post screen, enabling users to disable specific WordPress filters on a post-by-post basis for greater control.

The plugin is particularly useful for developers and content creators who wish to integrate custom snippets into their posts seamlessly. While the free version restricts editing to the Text tab, upgrading to the Pro version allows for switching between the Text and Visual editors without losing formatting. Note that full compatibility with the Gutenberg editor is limited, and users may need to utilize the Classic Editor plugin to access all features effectively.
