Captcha Code

82 Quality Score

Active Installs

23/30

With 100,000 active installs, the plugin has meaningful adoption but sits behind the 200,000 to 300,000 install leaders in this category.

Update Freshness

25/25

A full maintenance score reflects a very recent update on 2026-04-14 and declared compatibility with WordPress 7.0.

User Rating

12/15

A 78 out of 100 rating from 35 reviewers is acceptable but not outstanding, and the small sample size limits confidence in the trend.

Support Health

8/15

Support health is the weak link: zero support threads and zero resolved cases, so there is no public track record of the developer responding to issues.

WP Compatibility

15/15

The plugin works with PHP 5.2 and WordPress 3.0 or newer, giving it one of the broadest compatibility ranges available.

What It Does

Captcha Code adds a captcha challenge to the WordPress login, registration, comments, and lost password forms to block automated submissions. It uses a simple image-based code rather than third-party services, which helps with GDPR compliance and keeps site traffic private. The plugin is aimed squarely at reducing spam on standard WordPress forms rather than contact forms built with plugins like Contact Form 7 or WPForms.

Who It's For

This plugin is a sensible fit for site owners running standard WordPress installations who want a lightweight, no-external-API solution to stop comment and registration spam. It works well on blogs, membership sites, and small communities that do not rely on third-party form builders. Older sites still running PHP 5.2 will also appreciate its low minimum requirements.

Who Should Skip It

If your site relies on Contact Form 7, WPForms, Elementor forms, or WooCommerce checkout forms, this plugin will not protect those surfaces. Anyone needing advanced bot detection, analytics, or honeypot plus captcha combinations should look at a more full-featured alternative.

The Bottom Line

Captcha Code is a competent, well-maintained, and broadly compatible solution for stopping spam on WordPress core forms, and its overall score of 81.59 reflects solid engineering with a thin support track record. The lack of public support threads and the narrow coverage of third-party forms are real drawbacks. It is a reasonable choice for traditional blogs and membership sites, but operators of complex form stacks will likely need a broader tool.

Pick CleanTalk when you want an all-in-one spam firewall that also protects contact forms, WooCommerce, and trackbacks, not just core WordPress forms.

hCaptcha for WP 91/100

Choose hCaptcha if you prefer a privacy-friendly external service that covers many more forms and integrations than Captcha Code.

Simple CAPTCHA with Cloudflare Turnstile 90/100

Go with Cloudflare Turnstile for an invisible, modern captcha that reduces user friction across a wider range of plugins.

CF7 Apps 90/100

Use CF7 Apps when your primary spam concern is Contact Form 7 submissions rather than the core WordPress login and comment forms.

ReCaptcha v2 for Contact Form 7 86/100

Pick this if you specifically need Google reCAPTCHA on Contact Form 7 forms and do not need protection on native WordPress forms.
