Alternatives to Screaming Frog for AI visibility, and what a crawl of your own server does not contain

Screaming Frog SEO Spider is a desktop crawler, and the thing it returns is a record of what your own server sent back: status codes, titles, canonicals, directives, rendered HTML, structured data, internal links. If what you need is a record of what ChatGPT or Gemini said about your business to somebody who asked an unbranded question, that record is held somewhere else and no crawl of your own site produces it. So the alternatives worth shortlisting depend on which half of the work you are buying, and the split is clean: one half is your site, the other half is somebody else's answer. The licensed version does add an LLM feature, and it is worth knowing exactly what that feature does before you count it as AI visibility.

What the feature table published on 20 October 2026 actually contains

Read the same day, with HTTP 200 and identical bytes to a Chrome on Windows agent and a Safari on macOS agent, the vendor's pricing page publishes a complete line by line split between the free version and the licence. The free version crawls up to 500 URLs and covers broken links and redirects, titles and meta data, meta robots and directives, hreflang, exact duplicate pages, XML sitemap generation and the site visualisations.

The licence adds, in the vendor's own words: scheduling, crawl configuration, saving and reopening crawls, JavaScript rendering, crawl comparison, near duplicate content, custom robots.txt, mobile usability, AMP crawling and validation, structured data validation, spelling and grammar checks, custom source code search, custom extraction, custom JavaScript, crawl with OpenAI and Gemini, the Google Analytics, Search Console and PageSpeed Insights integrations, accessibility auditing, link metrics integration, forms based authentication, segmentation, the Looker Studio crawl report, and technical support. Licences are per user, last one year, and are sold in four volume bands at one to four, five to nine, ten to nineteen, and twenty or more. The crawl ceiling on the paid version is set by the memory and storage you allocate rather than by a number in the plan.

Setting the crawler up and reading its reports in a useful order is covered already in the SEO Spider setup and first crawl guide, including the free against licence split in table form and the published licence price. This page is about what to buy alongside it or instead of it.

Crawl with OpenAI and Gemini, described precisely

This is the line that gets mistaken for AI visibility monitoring, and the distinction is simple once stated. The feature lets the crawler call an OpenAI or Gemini API while it crawls and store the response as a column against each URL. You are asking a model to look at your page, on your instruction, with your prompt. That is genuinely useful: it classifies pages at scale, drafts missing descriptions, and flags content that does not answer its own title.

An AI visibility reading is the other direction. A buyer who has never heard of you asks a question with no brand name in it, an assistant assembles an answer from pages across the web, and the reading records whether you were named, who was named instead, and which sources the answer was built from. One measures your pages. The other measures somebody else's recommendation. Both are worth money and neither substitutes for the other.

Match the alternative to the job

The URL level version of this is worth doing before you buy anything, and the crawl, indexing and citation test for a single URL sets out the three checks in order, which is the cheapest way to find out whether your problem is access, indexing or absence from the answer.

One thing its own pricing document does, and we did the same thing first

Screaming Frog Ltd is a UK company. Its address in Henley on Thames and its VAT number are printed on the page. On 20 October 2026 the pricing page served four dollar figures and zero pound figures and zero euro figures in the document itself, under both user agents we tried. The pound and euro versions exist behind a currency switcher, which means a script has to run before they are in the page. An assistant asked what the licence costs in pounds is reading a document that answers in dollars.

We are naming it because we had the identical defect and it is on the record. Fetched as GPTBot, our own pricing page served rupee figures only. It was repaired on 16 October 2026 with a chapter that prints every plan in every region on every request. The lesson is the same for everybody: put every currency in the document, because the reader you most want has no browser.

What each vendor publishes, and where this one beats us

The only ranking we use is a stated criterion: what does the vendor publish that a buyer can verify without a sales call. On that measure Screaming Frog beats us outright on product documentation. It publishes a complete free against licence feature matrix, line by line, with 31 capabilities marked on each side, a running version number on the pricing page, the licence term, the volume bands, and a plain statement that the crawl ceiling depends on allocated memory. We do not publish a matrix at that granularity for our own plans, and we should.

What we publish that is checkable is the method behind a reading and our own failures with it: the question bank, the engines each reading used, the rule that keeps our own brand name out of every test prompt, and the result that 1,260 readings produced 6 citations of us, zero in the United States and zero on Gemini. Published failures are the part of this criterion almost nobody in either category offers, and the readings behind those numbers are on our proof page.

Questions buyers ask about Screaming Frog and AI search

Can Screaming Frog tell me if ChatGPT recommends my business?

No, and it does not claim to. It reports what your server returned and, with a licence, what an OpenAI or Gemini API said about a page you pointed it at. A recommendation reading comes from asking the assistants buying questions with your brand name absent and recording the answers.

Is the free version enough for AI search work?

For a site under 500 URLs it covers the access and indexability checks that matter most: directives, canonicals, redirects and duplicates. The two lines you will miss are JavaScript rendering, which tells you whether your content exists before a script runs, and saved crawls, which is how you compare this month with last.

What is the best free alternative?

Google Search Console plus a 500 URL crawl covers a surprising amount, because the crawler tells you what your site returns and Search Console tells you what Google did with it. For AI crawler access specifically, read your own robots.txt and your raw server logs before buying any tool.

Does it crawl like an AI crawler does?

You can set the user agent, which is how you check whether your server treats a named AI agent differently from a browser. That is a real and useful test, and it answers an access question rather than a recommendation question.

Should I buy a crawler or a monitoring tool first?

Crawl first, because an access or indexing fault makes every later reading meaningless, and the crawl is free up to 500 URLs. Then measure the answers, because once the pages are reachable the remaining gap is usually on third party pages rather than on yours.

The two exports that belong side by side

Put your crawl export next to a list of the pages assistants actually quoted when buyers asked about your category, and the comparison is immediate. Pages you consider central are often absent from the second list, and pages you forgot about are carrying the answer. That mismatch is the most actionable thing a technical team can be handed, because it reorders the backlog by what is already being read rather than by what you meant to be important. AI Knows Us produces the second list with the cited URLs attached, which is what makes the two exports comparable in a spreadsheet.
