Hey Product Hunt 👋 I'm Berkcan, the maker of IPScanner.

IPScanner started with one question: who is on the other end of this visit? A customer, Googlebot, an AI crawler, or a script on a cloud server behind a VPN?

It answers that for every visitor to the site you already run, and you decide what happens to each kind:

• People get in. They never see a puzzle or a challenge

• Verified crawlers like Googlebot always get in. A fake Googlebot does not

• AI crawlers like GPTBot are your call: allow, flag or block

• Headless browsers, Tor exits and card testers are stopped. On WooCommerce that happens before the charge is attempted

• On signup forms it checks the email too: throwaway inboxes, typos like gmial.com, domains with no mail server

The part I care most about: it starts in monitor mode. At first it blocks nothing and shows you who it would stop, with the reason for each decision. You turn on blocking one kind at a time, and the change reaches your site within a minute. If IPScanner is ever slow or down, your visitors are let in.

It runs on Cloudflare, WordPress, WooCommerce, Traefik, Caddy and nginx, and on any signup form. It sets no cookies on your visitors.

Pricing is prepaid credits with no subscription. Monitoring is free. Blocking costs one credit per visitor check, packs start at $5, and new accounts can claim 25,000 free credits.

I'd love your help with two things. Run it on your own traffic and tell me what it gets wrong. And tell me which platform I should support next.

I'll be in the comments all day.
