🆚 Akismet vs. Cloudflare Turnstile

Akismet is a comment spam filtering service originally developed for WordPress that can also be integrated with other CMS and forums.

Cloudflare Turnstile is a user-friendly CAPTCHA alternative that verifies human visitors without requiring them to solve interactive puzzles or identify objects.

It works by running invisible background tests such as proof-of-work calculations and checks for browser quirks to analyze the visitor's environment and behavior, supports Private Access Tokens (PATs) to validate devices without tracking, and offers a free API.
