I also have experience 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). Prism.JS has 9k stars on GitHub while HighlightJS have 18.2k stars. Both libraries are used by major companies.

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 (prismjs.com and highlightjs.org). so, we have options to go with which syntax library we like and which theme we like.

Prismatic developers launched 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 the No.1 Free Syntax Highlighting plugin.

Conclusions

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 trust 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 has js, and 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 highlighting plugins?
yes, I used many, and based on my experience I choose Prismatic & it is the Best and top Syntax Highlighting Plugin for WordPress.
