Really Simple CAPTCHA – Overall replacement

Really Simple CAPTCHA is a tiny CAPTCHA library from Takayuki Miyoshi, the author of Contact Form 7, that generates image challenges locally with no external calls. Against Simple Cloudflare Turnstile, it avoids any dependence on a third-party service and keeps everything on your server. What it does not do: it is not standalone protection and is designed to be used by other plugins like Contact Form 7 rather than dropped onto arbitrary forms.

Choose Really Simple CAPTCHA if you use Contact Form 7 and want a self-contained image CAPTCHA.

Advanced Google reCAPTCHA – Site-wide reCAPTCHA

Advanced Google reCAPTCHA applies Google reCAPTCHA to login, registration, comment, and lost-password forms across WordPress. Against Simple Cloudflare Turnstile, it focuses on protecting core WordPress forms rather than just contact forms. What it does not do: it ties you to Google reCAPTCHA specifically, which some visitors and privacy regimes prefer to avoid.

Choose Advanced Google reCAPTCHA if you want Google reCAPTCHA on all the default WordPress forms.

reCaptcha by BestWebSoft – Broad form coverage

reCaptcha by BestWebSoft from BestWebSoft adds Google reCAPTCHA to WordPress and many popular form and commerce plugins. Against Simple Cloudflare Turnstile, it integrates with a wide range of third-party forms out of the box. What it does not do: some integrations and reCAPTCHA versions are gated behind its Pro edition, and the admin pushes that upgrade.

Choose reCaptcha by BestWebSoft if you need reCAPTCHA wired into many different plugins.

CAPTCHA 4WP – Flexible placement

CAPTCHA 4WP, now known as CAPTCHA 4WP from Melapress, lets you place CAPTCHA on custom forms and supports multiple reCAPTCHA versions. Against Simple Cloudflare Turnstile, it gives finer control over where challenges appear. What it does not do: multisite support and some advanced placement features require the premium version.

Choose CAPTCHA 4WP if you need precise control over where CAPTCHA appears.

hCaptcha for WP – Privacy-friendly, free

hCaptcha for WP integrates hCaptcha, a privacy-focused alternative to Google, across WordPress and dozens of form plugins for free. Against Simple Cloudflare Turnstile, it offers a similar no-cost, privacy-minded challenge with very broad form support. What it does not do: hCaptcha still relies on an external service, and its interactive challenges can be more intrusive for visitors than Turnstile’s invisible checks.

Choose hCaptcha for WP if you want a free, privacy-focused CAPTCHA with wide integrations.
