Knocklog vs Cloudflare AI Crawl Control vs Known Agents
All three show which AI agents visit your site, but they were built for different situations. This comparison says where each one is best, including when the answer is not Knocklog.
Checked on 9 November 2026
In short
If your site already runs through Cloudflare and what you want is to block or charge AI crawlers, Cloudflare AI Crawl Control is the natural choice: it is free on every Cloudflare plan and acts at the edge, before requests reach your server.
If you run on a cloud (AWS, Google Cloud, Vercel, Fastly, Akamai) and want agent analytics with bad-bot blocking, Known Agents (formerly Dark Visitors) covers that well.
If your site is on any host, including cPanel and shared hosting, and you want to know which agents are genuine, with proof, how many visitors and leads AI assistants send you and, on Business, which companies visited, Knocklog was built for that, in English and Portuguese.

When to pick Cloudflare
Your domain is already proxied by Cloudflare, you want to decide at the edge which crawlers get in, and maybe charge for access. The console shows each crawler's activity and whether it follows robots.txt. What it does not show is what happens next: the people ChatGPT or Perplexity sent to your site and what they did.
When to pick Known Agents
Your infrastructure is on one of the clouds it connects to and you want agent analytics with bad-bot blocking and a robots.txt that updates itself. Its Startup plan costs less than Knocklog Pro.
When to pick Knocklog
Your site is on ordinary hosting with no Cloudflare in front: Knocklog reads cPanel logs, runs as a WordPress plugin or as middleware on your server.
You need proof: every visit that claims to be ChatGPT, Claude or Googlebot is checked, and impostors show up with the reason. And you want to tie agents to results: how many people each assistant sent, which became a form or WhatsApp lead and, on Business, which companies the visits came from.
Using them together
Yes. If you already use Cloudflare, keep AI Crawl Control to block, and install Knocklog in one click through Cloudflare to measure, verify and tie visits to leads.
