No.1 Best Syntax Highlighter WordPress Plugin Free

This post is really based on my experience. You will be surprised when you work with these 2 plugins. I use Gutenberg for my articles. I also have experienced with elementor page builder So here I’ll share 2 plugins. One is a free Prismatic Plugin and the second one is PRO (only for elementor) Coder – Syntax Highlighter for Elementor. I use Prismatic because it is free and compatible with Gutenberg. Prismatic Plugin has 2 major syntax highlighter libraries. (Prism.js and Highlight.js). PrismJS have 9k stars in GitHub while HighlightJS have 18.2k stars. Both libraries are used by major companies. I studied both syntax highlighter libraries and found the 2 best plugins based on these libraries.

My opinion about Prismatic is honest. First of all, it’s free and has positive reviews. As I mentioned above this plugin has 2 major syntax highlighter libraries ( and so, we have options to go with which syntax library we like and which theme we like.

Prismatic developers lunched monthly updates.

Regular Update is a great thing about a free theme/plugin and Prismatic Syntax highlighting for a WordPress plugin comes with monthly updates or something update comes twice a month. That’s why I have chosen this plugin as a No.1 Free Syntax Highlighting plugin.

How do you make a syntax highlighter?

Final words. If you are using Gutenberg then go with Prismatic Plugin (Prismatic WordPress) and if you are using Elementor page builder then go with Coder – Syntax Highlighter for Elementor. I personally like Prismatic and I use it for my regular posts to display code highlighted. Coder is paid plugin but trusts me it’s cool I test it out deeply, BUT WHY do I CURRENTLY USE PRISMATIC INSTEAD OF CODER? Well, the answer is simple I do not like using Elementor for writing articles and blogs because these plugins have their own js and CSS files which increases page load time, every page builder have js, CSS files like Elementor, WP Bakery Builder, Yellow Pencil, etc these plugins are best to design pages and I mostly use these Page builder plugins only for page designing but for articles I only go with WordPress default Page builder which is Gutenberg. Hope so you will understand why I prefer Prismatic Free Syntax Highlighter Plugin.

Did I use other free syntax or code highlighter plugins?
yes, I used many, and based on my experienced I choose Prismatic & it is the Best Syntax Highlighting Plugin.
