Biggest opportunity: Swap “block”, “php” and “code” for “beautiful”, “bloat” and “no bloat”. “block” isn't earning its slot: you're not in the first 24 results for its own search. “beautiful” sits at #9 untagged, close enough for a declared tag to move it up. “php” isn't earning its slot: you're not in the first 24 results for its own search. “bloat” sits at #14 untagged, close enough for a declared tag to move it up. “code” isn't earning its slot: it only gets you to #16. “no bloat” sits at #14 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

of downloads still active
At least 10K of 175.8K lifetime downloads are still running, above its category: the median Blocks plugin keeps 2.1%, across 1,578 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Blocks plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
This plugin shipped 1 release in the last 12 months, and every existing install that updated counted as another download. wp.org publishes no split between first installs and updates, so we show the raw rate rather than guess at one.

What to do about it
- Swap “block”, “php” and “code” for “beautiful”, “bloat” and “no bloat”. “block” isn't earning its slot: you're not in the first 24 results for its own search. “beautiful” sits at #9 untagged, close enough for a declared tag to move it up. “php” isn't earning its slot: you're not in the first 24 results for its own search. “bloat” sits at #14 untagged, close enough for a declared tag to move it up. “code” isn't earning its slot: it only gets you to #16. “no bloat” sits at #14 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.
- One page off on “code”. #16 puts you just past the first ten results, where almost all the clicks stop. The gap to close is small.

There’s a lot to like here, except that there is no way to set a site-wide syntax-highlighting theme – it’s done block-by-block, separately for every code block.

Code Block Pro is one of the best syntax highlighting plugins for WordPress. Clean, fast and very easy to use. Code snippets look great right away with almost no setup. Highly recommended for anyone publishing code on their site. Thank you very much!

Leaving a 5 star for the simplicity. Plenty of languages, themes and styles.

In 15 years of using and developing wordpress websites, I’ve never left a review for a plugin. But I’m compelled to do so for this one. There’s no bloat. No notices in the admin panel, no upselling, no ads, no nagging to upgrade to pro, nothing at all. Goes to show the author values and respects their users and not just see them as walking talking wallet. This is how all plugins should be. But that doesn’t mean the plugin is devoid of features. It has everything you would want from a syntax highlighter plugin and more. The code looks beautiful and it’s fast. Did I mention, there’s no bloat. What a breath of fresh air.

I had a problem with Shortcodes inside the code (so inside the block)I put the shortcode model in a comment of the code. And even if the plugin has an option that does not listen to shortcodes. Those with “options” added were still listened to. The programmer solved it on the fly in 2 hours, it’s super fast. A_So I can only say that it is a great plugin.B_Excellent free assistance.C_And I can assure you that I looked for a code block or code syntax plugin, and this is the only decent one. Others were also decent, but they have not been updated for years and unfortunately the last one died with wp 6.8 So yes, for now in 2025 I consider it the best, if not almost the only one. ___________________________________________The correct problem_________________________________________ Serious, some codes are read by the system and become critical errors. I chose it because it seemed good to me. I had an old plugin that they haven’t updated for 5 years and it ends up that with the new wp 6.8 it no longer shows the graphic template. I searched a bit and chose this one. But problem!it reads some codes anyway: ————————- I use a function loaded on the site with WPCode, and I created a guide on the code in question. When I open the article it gives me an error because WP sees the same function name, instead it shouldn’t even read it.So to test it I put CSS Editor, so that it doesn’t read the php anyway. But the problem remains. I have to rephrase this sentence:It is not the name of the function itself, but the shortcode comment code that is read.Fairly less serious, but problematic. // Add Shortcode - scrivi questo campo [aggiungi_subcategorie] [aggiungi_subcategorie category_data="product_brand"]// NOTA: in avada, usare il campo TESTO e non la sotto variante del campo testo SHORTCODE, altrimenti non vedeadd_shortcode( 'aggiungi_subcategorie', 'wpcode_subcategorie_inpag_archivi_shortcode', 7 );function wpcode_subcategorie_inpag_archivi_shortcode($atts = array(), $content = null) { [ aggiungi_subcategorie ] exists on the site and in fact it gives me an error. Not only that, I use Avada as a theme and I wanted to show a created Template, so I put the Avada code in the plugin block. the theme tries to read it and gives a critical error. If I put the same code in the guthenbergh CODE base, there are no problems. I find it very serious that this plugin allows the site to read codes. This topic was modified 1 year ago by yukiko-kawa.

I first tried another similar plugin from a dev I really trust. But it was garbage. Decided to try Code Block Pro and the free version rocks. It’s SO MUCH BETTER. So easy to use. Settings right there in the post editor where they belong…Love it so much just purchased the extra themes back. It was only $12. Crazy good deal.

Beautiful, many themes included, looks professional, includes copy button. All perfect!

This plugin does exactly what you’d hope, clean syntax highlighting, easy to use, and packed with thoughtful features. It’s really well-built and feels lightweight yet powerful. Honestly, it’s adding real value to the WordPress space. Great work!
