Doorman vs the alternatives
Captchas check whether a visitor is human. Spam filters match what they've seen before. Fraud platforms need a sales call. Doorman reads what each submission says. Here's how it compares, including when something else is the better fit.
Captchas and bot checks
Doorman vs reCAPTCHA
reCAPTCHA scores whether a visitor behaves like a human. Doorman reads what they sent, so a person pasting pitches is kept out too.
Compare →Doorman vs hCaptcha
hCaptcha scores visitor behaviour and may show a challenge. Doorman reads the message, so paid human pitches are caught too.
Compare →Doorman vs Cloudflare Turnstile
Turnstile is a free, mostly invisible bot check. It doesn't read the message, so typed pitches and scams get through.
Compare →Doorman vs Friendly Captcha
Friendly Captcha is a privacy-first, invisible proof-of-work captcha. It slows bots but doesn't read what people type.
Compare →Spam filters
Doorman vs Akismet
Akismet is the long-standing WordPress spam filter. Doorman works on any stack, explains every decision and costs less at volume.
Compare →Doorman vs CleanTalk
CleanTalk is a cheap, unlimited CMS plugin built on blacklists and bot tests. Doorman reads what a first-time sender actually asks.
Compare →Doorman vs OOPSpam
