80 Quality Score

The plugin was last updated in late June 2026 and is actively maintained, which is a strong signal for long-term reliability.

User Rating

15/15

It holds a perfect 100 out of 100 score, though this comes from a small pool of only 8 reviews, so the rating should be read with some caution.

Support Health

What It Does

DS CF7 Math Captcha adds a simple arithmetic challenge to any Contact Form 7 form, requiring visitors to solve a math problem before they can submit. It includes a refresh button so users can generate a new question if they find the current one too hard, helping block automated spam bots that cannot solve basic math.

Who It's For

This plugin is well suited to small site owners who already rely on Contact Form 7 and want a lightweight, low-friction spam barrier without adding third-party services or tracking scripts. It fits neatly into local business sites, portfolios, and contact pages where one or two forms need protection.

Who Should Skip It

Anyone running high-volume forms or sophisticated spam attacks should look elsewhere, since a static math puzzle is easier for modern bots to bypass than image-based or behavioural CAPTCHAs. Sites that do not use Contact Form 7 will get no value from this addon at all.

The Bottom Line

DS CF7 Math Captcha delivers a focused, narrowly useful feature with strong maintenance signals and a perfect, if thinly sampled, rating. Its overall quality score of 80.41 is solid for such a small utility, but the limited install base and minimal support history mean larger or higher-risk sites should consider proven alternatives like hCaptcha or Cloudflare Turnstile.

Choose CleanTalk when you need broad spam protection across comments, registrations, and forms rather than a CF7-only math puzzle.

hCaptcha for WP 91/100

Pick hCaptcha when you want stronger bot resistance and privacy-first image challenges covering more than just Contact Form 7.

Simple CAPTCHA with Cloudflare Turnstile 90/100

Go with Cloudflare Turnstile if you prefer invisible or frictionless bot detection backed by a major infrastructure provider.

CF7 Apps – Honeypot, Database, Redirection, Webhook, and Addons for Contact Form 7 90/100

Use this bundle when you want a CF7 honeypot plus several form addons in a single lightweight package.

Database Addon for Contact Form 7 – CFDB7 88/100

Pick CFDB7 when your main need is storing CF7 submissions in WordPress rather than adding a captcha layer.
