About
All-in-one Syntax Highlighting solution. Full Gutenberg and Classic Editor integration. Graphical theme customizer. Based on EnlighterJS.
What It Does
Enlighter is a syntax highlighting plugin that adds colour-coded code blocks to WordPress posts and pages, with built-in support for both the block editor and the classic editor. It includes a graphical theme customizer so you can tweak colours, fonts, and token styles without writing CSS. Under the hood it uses the EnlighterJS library to render a wide range of programming languages and markup formats.
Who It's For
This plugin is a strong fit for developers, technical writers, educators, and publishers who regularly embed code snippets in tutorials, documentation, or blog posts and want them to look polished and readable. It also suits small teams that maintain a knowledge base or training portal and need a consistent, theme-able code presentation across many articles.
Who Should Skip It
If your site rarely shows code or only needs the occasional unstyled snippet, a lighter solution such as the built-in code block or a single-purpose highlighter will be enough. Users on outdated PHP versions below 7.4 or WordPress installations older than 6.8 should also skip it, as it will not run on those environments.
The Bottom Line
Enlighter earns a 79.81 out of 100 and delivers exactly what its small but enthusiastic user base wants: reliable, theme-able syntax highlighting with solid modern WordPress compatibility. The main caveat is the absence of public support activity, so buyers should be comfortable relying on documentation rather than forum responses. If code presentation matters to your site and you meet the PHP 7.4 and WordPress 6.8 minimums, it is a safe pick.
Related Plugins
Pick this instead if your only concern is reverting to the classic editor rather than highlighting code, since it is a far more popular plugin with 500,000 installs.
Choose this if you want broader classic editor enhancements beyond highlighting, given its 1,000,000 installs and broader editing feature set.
Reach for this when you simply need to disable the block editor site-wide, with 9,000,000 installs making it the de facto standard for that purpose.
Use this if you want classic editor restoration plus extra toolbar customisation, rather than a dedicated syntax highlighting tool.
Select this if reverting both the editor and widget screens is the priority, since it bundles both roles into a single 20,000 install plugin.
