Akismet Anti-spam: Spam Protection vs Simple CAPTCHA with Cloudflare Turnstile (2026): PluginCheck
Quick Verdict
Pick Akismet if your main concern is comment spam on a blog or content site; it is the proven default for that job.

Privacy posture
Cloudflare Turnstile is privacy-preserving and does not track visitors the way a comment-filtering API can, making it a stronger fit for sites with strict GDPR or PIPEDA requirements.
Price and licensing
Turnstile is 100% free with no usage tiers, while Akismet requires a paid plan once monthly spam checks exceed the commercial allowance.
Coverage across non-comment forms
Turnstile integrates with login, registration, WooCommerce checkout, and contact forms out of the box, which is useful if your spam problem is bots hitting endpoints other than comments.

For the most common WordPress use case, blocking comment spam on a blog or content site, Akismet is the safer default and the one I would pick first.
