with fake data.

Why SpamKill

You tried CAPTCHAs.
They made things worse.

CAPTCHAs punish your real visitors with puzzles while bots solve them for pennies. Cloudflare blocks entire visitors at the edge — you never know what business you lost. SpamKill works at the form level, invisibly, with zero conversion impact.

I had a web form giving me upwards of 20 spam submissions a day. I followed the instructions and immediately my spam went completely to zero. Probably the most no-brainer, easiest solution for spam I've ever seen.

Very simple and effective tool that eradicates all bot signups and spam signups. Acts as a really good perimeter defence. Since installing SpamKill, we haven't had a single bad contact added. Very cost effective — does exactly what it says on the tin.

SpamKill has been how we "got in the door" and converted several prospects into clients. We install it free for a month — if we stop the spam, they switch to us. 100% success rate. Truly one of the best tools we have for getting new clients.

Why us

Built by automation engineers who moved to security.

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.
