The short answer

Both tools are free, skip the signup, and hand you ready-to-paste fixes — so they are genuinely close. Pick LLCrawler if you want it to stay $0 forever with no paid tier, work in English or Spanish, and generate the actual files for you: llms.txt, a JSON-LD schema kit, a shareable badge, and a Markdown agent prompt you can drop into ChatGPT or Claude. Pick SiteTest.ai if you prefer its clean A–F grade and you are willing to pay $4.99–$24.99/mo for developer briefs and re-audit credits. SiteTest is English-only today. For most people who just want one fast, free, no-strings audit, LLCrawler is the simpler call.

Honest note: we build LLCrawler. We still think the answer above is fair. If you disagree, email us — we will update this page.

Frequently asked questions

Are both LLCrawler and SiteTest.ai really free?

Yes. LLCrawler is 100% free with no paid tier at all. SiteTest.ai has a free core audit (no signup, no card) but gates advanced features like developer briefs and re-audit credits behind paid tiers from $4.99 to $24.99/mo.

What is the biggest difference between them?

LLCrawler stays $0 forever, works in English and Spanish, and generates the actual files for you — llms.txt, a JSON-LD schema kit, a shareable badge, and an agent prompt. SiteTest.ai is English-only, uses an A–F grade, and reserves developer briefs and re-audits for paid plans.

Does either one require a signup?

No. Neither tool requires a signup or a credit card to run the free audit. You paste a URL and get your report.

Which one is better for non-English sites?

LLCrawler. It is fully bilingual in English and Spanish, so the audit and report come back in your language. SiteTest.ai is English-only today.

Do both actually give me fixes, not just a score?

Yes. Both ship ready-to-paste fixes rather than only a score. LLCrawler goes further by generating the files themselves and a Markdown agent prompt you can hand to ChatGPT or Claude; SiteTest.ai ships code fixes too but puts its deeper developer briefs behind paid tiers.
