CDN and edge control

AI Crawler Check vs Cloudflare AI Crawl Control

Cloudflare AI Crawl Control is an enforcement layer: it sits in front of your site and can allow, block or charge AI crawlers. AI Crawler Check is a verification layer: it stands outside and reports what the world can actually see. If you use Cloudflare, you want both, because enforcement without independent verification is how sites end up blocking crawlers they meant to welcome.

Short answer

Cloudflare AI Crawl Control is the better tool for controlling AI crawler access, and it is free on all Cloudflare plans. AI Crawler Check is the better tool for verifying the result from outside, on any site, including sites not on Cloudflare. Use Cloudflare to set the policy and AI Crawler Check to confirm the policy does what you intended.

Choose Cloudflare AI Crawl Control when

You need to actually block or allow AI crawlers, not just find out what they can reach. Enforcement is their job, not ours.
Your site is already on Cloudflare, where it is available on all plans with no configuration.
You want per-crawler allow and block policies managed from one dashboard.
You want to see which crawlers ignore your robots.txt and enforce against them at the edge.
You are exploring paid access to your content, such as pay per crawl.

Choose AI Crawler Check when

Your site is not on Cloudflare, so an edge dashboard is not available to you at all.
You want an independent, outside-in check that your policy behaves as you intended, rather than the dashboard reporting on itself.
You are auditing a site you do not control, or do not have dashboard access to.
You want the wider GEO picture as well: llms.txt, schema, HTTPS and the rest of the 58 checks in one report.
You need to audit many sites quickly, up to 20 at a time.

Side by side

AI Crawler Check compared with Cloudflare AI Crawl Control
What you are comparing	AI Crawler Check	Cloudflare AI Crawl Control
Comparable. Primary function	Verify and explain what AI crawlers can currently reach	Enforce what AI crawlers are allowed to reach
Advantage Cloudflare AI Crawl Control. Can it block a crawler	No. It is a read-only audit and never changes your site	Yes. Allow and block rules per crawler at the edge
Advantage AI Crawler Check. Requires your site on a specific platform	No. Any public URL on any host	Yes. The site must be a Cloudflare zone
Advantage AI Crawler Check. Requires dashboard access	No	Yes, you must own or be granted access to the zone
Comparable. Vantage point	Outside in. Sees what a crawler sees, including your WAF turning it away	Inside out. Sees requests that reached the edge
Advantage Cloudflare AI Crawl Control. Live traffic analytics	None. Point-in-time configuration snapshot	Yes. Request volumes and patterns per crawler
Comparable. robots.txt compliance tracking	Parses your robots.txt and shows which rule applies to each bot, and why	Tracks which crawlers violate your directives and can enforce against them
Advantage Cloudflare AI Crawl Control. Monetisation of crawler access	Not offered	Pay per crawl, with 402 Payment Required responses
Advantage AI Crawler Check. Detects a WAF blocking robots.txt itself	Yes, and reports it as a WAF block instead of a missing file	The WAF is theirs, so this failure mode is not a surprise to the dashboard
Advantage AI Crawler Check. Wider GEO and AI readiness checks	58 checks across 5 categories with a 0 to 100 score	Out of scope
Advantage AI Crawler Check. Bot reference documentation	297 directory pages covering 196 bots and 91 operators	Crawler list within the dashboard
Comparable. Cost	Free, no sign-up	Free on all Cloudflare plans, but requires being a Cloudflare customer

Enforcement and verification are not the same job

This comparison is unusual because the honest answer is that Cloudflare wins the headline capability. If your goal is to stop GPTBot from reading your archive, Cloudflare AI Crawl Control can do that and AI Crawler Check cannot. We are a read-only audit. We never change your site.

So why compare them at all? Because a control panel and an independent check are different instruments, and control without verification is where the expensive mistakes live.

The failure mode nobody plans for The most common serious problem we see is not a site that blocks too little. It is a site that blocks far more than the owner believes. A broad bot rule, a security preset, or a managed ruleset intended to stop scrapers also turns away the retrieval crawlers that fetch pages to cite in AI answers. The dashboard reports the rule working exactly as written. Nobody notices, because a rule doing its job does not look like an incident.

An outside-in audit catches this because it does not read your configuration, it reads your site the way a crawler does. If a crawler cannot get in, that shows up regardless of which layer stopped it: robots.txt, a firewall rule, a managed ruleset, or a bot-fighting mode nobody remembers switching on.

Training crawlers and retrieval crawlers deserve different answers

The strategic point that gets lost in the blocking conversation: not all AI crawlers do the same thing, and blanket rules cannot tell them apart.

Training crawlers collect text to train future models. Blocking them is a legitimate content and licensing decision, and plenty of publishers make it deliberately.
Retrieval crawlers fetch a page because a user just asked a question it might answer. Blocking these removes you from AI answers. For most commercial sites this is self-harm, not protection.

Some operators run both, under user-agents that differ by a suffix. This is why we sort every one of the 196 bots we track into 8 categories and 6 priority tiers rather than reporting a single allowed or blocked count. The score guide explains how the distinction is weighted, and training bots vs search bots covers the strategy.

If you are not on Cloudflare

Worth stating plainly, because it decides the question for a lot of readers: AI Crawl Control requires your site to be a Cloudflare zone. If you are on another CDN, a managed platform, or no CDN, the comparison ends there. A URL-based audit works regardless of what is in front of your origin.

The recommended combination

Decide policy deliberately. Which crawlers do you want reading your content, and for what purpose? Answer this before touching any dashboard.
Enforce it where enforcement belongs. On Cloudflare, that is AI Crawl Control. Elsewhere, robots.txt plus your own WAF. Our robots.txt generator produces rules that follow the standard correctly.
Verify from outside. Run the free AI crawler check and confirm the result matches the intent. This is the step most teams skip, and it is the only one that catches a rule that is working perfectly at doing the wrong thing.
Re-verify after any infrastructure change. New WAF rules, plan changes and security presets all move the line.

Where we would send you elsewhere If you need to block crawlers, monetise crawler access, or see live per-crawler request volumes, use Cloudflare AI Crawl Control. Those are its jobs and it does them well. Come back for the independent verification pass.

Frequently asked questions

Can AI Crawler Check block AI crawlers for me?

No, and it never will. It is a read-only audit that fetches public files and reports what it finds. Blocking belongs at your edge or in your robots.txt. We show you what to change and the robots.txt generator writes correct rules, but you apply them.

I already use Cloudflare AI Crawl Control. Why run an external check?

Because the dashboard reports on its own rules, and the common failure is a rule working correctly while doing something you did not intend. An outside-in check sees the combined effect of robots.txt, your WAF, managed rulesets and bot modes together, which is what a crawler actually experiences.

Does AI Crawler Check work if my site is not on Cloudflare?

Yes. Any publicly reachable URL on any host. That is the main practical difference: AI Crawl Control needs your site to be a Cloudflare zone, we only need a URL.

Will Cloudflare bot protection make my site look blocked in your report?

It can, and we report that honestly rather than guessing. If a WAF blocks our fetch of your robots.txt, the report says the request was blocked by a firewall instead of claiming the file is missing. Those are different problems with different fixes, and conflating them sends you off to solve the wrong one.

Should I block all AI crawlers to protect my content?

Rarely the right call as a blanket policy. Training crawlers and retrieval crawlers do different things: blocking training is a licensing decision, while blocking retrieval removes you from AI answers entirely. Decide per category. The score guide and training vs search bots explain the trade-off.
