SpamKill analyzes behavior, not content. Bots fill forms differently than humans — we block them at 99.9% accuracy. And the rare real person we're unsure about always has a path through, so nothing is silently lost. No CAPTCHAs. No friction.
Different businesses feel bot attacks differently. Pick the one that sounds like your morning, and we'll show you exactly how to fix it.

SpamKill creates two versions of every form. Humans see a clean experience. Bots see an incomprehensible maze. No CAPTCHAs. No friction.
Checkbox CAPTCHAs punish real visitors while solver farms pass them for pennies. The invisible generation — reCAPTCHA v3, Turnstile, edge bot protection — dropped the puzzles but kept the failure mode: they decide before a submission exists, so a mistake means a lead that was never captured and no record it was ever there. SpamKill decides after capture, at the form level. Worst case with us is a review. Worst case with a gate is a lead you'll never know you lost.
Works with any form, any platform, any tech stack. No backend changes required.
The Form Transformer runs your actual HTML through the same API that protects forms in production — and hands back the protected version. No signup, no card, nothing to install.
Two realities, generated from your own markup.
We know how bots evade detection because we've spent years inside the automation ecosystem — understanding the tools, techniques, and patterns from the engineering level, not from a security textbook. That depth of expertise is our competitive edge — and the foundation of patent-pending form transformation technology nobody else has.
SpamKill doesn't bolt security onto your forms as an afterthought. We transform them at the DNA level — randomizing fields, injecting intelligent honeypots, analyzing behavioral signals — all invisibly.
Whether you're a small business owner or running million-dollar funnels, the first step is the same — find out what's real and what's not.
