54 Quality Score
Active Installs
19/30

With 20,000 active installs the plugin has a respectable niche audience, far smaller than mainstream snippet tools but still meaningful for a specialised display utility.

Update Freshness
7/25

The plugin was last updated on 3 March 2025, but the maintenance score of 42 reflects a long gap between earlier releases and the fact that it has historically been updated in bursts rather than continuously.

User Rating
13/15

A rating of 86 out of 100 from 86 reviews is a strong user satisfaction score for a plugin in this category.

Support Health
8/15

Only one support thread exists in the record and it was resolved, giving a perfect resolution rate but a very thin sample that limits confidence.

WP Compatibility
8/15

The plugin is tested with WordPress 6.7.5 and requires PHP 7.0, which is broad coverage, though the compatibility score of 50 suggests some signals (such as WordPress version testing depth or PHP 8.x declarations) are not fully current.

What It Does

SyntaxHighlighter Evolved wraps code blocks posted in the WordPress editor with a syntax highlighter that renders languages like PHP, JavaScript, HTML, CSS, and many others in a colour-coded, line-numbered display. You paste raw code between shortcode tags and the plugin handles the styling, copy buttons, and client-side highlighting without modifying your snippets.

Who It's For

This plugin is a good fit for developers, technical bloggers, and educators who regularly publish code samples on WordPress and want a polished, readable display without manually formatting each block. It works best on sites where visitors are expected to read and study code rather than just glance at it.

Who Should Skip It

If you only post code occasionally or just want basic block formatting, the native WordPress code block or a lighter plugin will do the job without the extra scripts and styles this plugin loads. Site owners focused purely on snippet insertion for execution (rather than display) should look at WPCode or Code Snippets instead.

The Bottom Line

SyntaxHighlighter Evolved does one thing well: rendering code samples in posts with clean, familiar syntax highlighting, and its 86/100 user rating backs that up. The 57.69 overall score, modest 20,000 installs, and sparse support history mean it is a capable niche tool rather than a must-install. Use it if displaying code is central to your site; otherwise the higher-scoring snippet managers above will serve broader needs.
