CAPTCHAs punish real users and let sophisticated bots through anyway. Bouncer scores every form submission on the server, catches disposable emails and bot patterns, and blocks the bad ones before they hit your inbox.

Keep your contact form clean without a "prove you're human" hurdle. Drop in one API call, keep your conversion rate.
