Our free SEO toolkit
SERP Simulator
Preview how your title and meta description render on Google Desktop, Google Mobile, and Perplexity AI Overview before you hit publish. Live character counters and truncation warnings. It's the only free simulator that covers Google and Perplexity in one view.
Sitemap Finder & Checker
Paste your domain or sitemap URL and we validate every URL for status codes, broken links, redirect chains and XML structure errors. Catches issues before Google does. Up to 100 URLs per check.
Schema Validator
Audit any page's JSON-LD against schema.org specs and Google Rich Results requirements. Errors, warnings and rich result eligibility in one report. No account, instant results.
llms.txt Generator
Paste your domain, and we generate a ready-to-host llms.txt file with categorized sections, title, and meta extraction from your top pages. Tell ChatGPT, Claude, and Perplexity what to read on your site.
How our free SEO tools work
No dashboards, no onboarding, no setup. Every tool is built around a single input and a single output.

SERP preview, sitemap validation, schema audit, or llms.txt generation. Each tool solves a specific problem.
Paste your URL or content.
No login screen, no email form, no credit card. Just the input you'd actually use.
Get the answer.
Results are clean, copy-paste ready, and built around the next action you'll take.
Built by SEOs, for SEOs
Every tool on this page came from a real problem we hit while doing SEO work. And they are a small piece of our work.
We built these free tools for the same reason SEOcrawl exists: because good SEO shouldn't require stitching together eight different tools and three browser tabs.

FAQs
Are these SEO tools really free?
Yes. These tools include no trial period, no freemium wall, and no “upgrade to see your results.” Every tool is free to use as many times as you need. No account required at any step.
Do I need to sign up or give my email?
No. You do not need to sign up to use the tools, not to see the results, not to copy the output. If you want to monitor your site continuously or save results over time, that's what the SEOcrawl platform is for.
How are SEOcrawl's free tools different from Ahrefs or Semrush?
Ahrefs and Semrush gate most free tools behind an account. SEOcrawl doesn't. Two tools here also don't exist in their free tiers at all: the SERP simulator with Perplexity preview and the llms.txt generator.
Can I use these tools for client work?
Yes. All tools are free with no account required. The only limit is one URL per check. For more extensive use, continuous monitoring or site-wide audits, the SEOcrawl platform has you covered.
What's the SERP Simulator and when should I use it?
It's a free tool that shows how your title and meta description render across Google Desktop, Google Mobile and Perplexity AI Overview before you publish. Use it before any new page goes live, after updating meta tags, or when testing title variations for CTR.
What is llms.txt and why does it matter for SEO?
llms.txt is a plain text file that tells AI crawlers (ChatGPT, Claude, Perplexity, Gemini) which pages on your site are worth reading and how your content is organised. Think of it as robots.txt for AI search. Early adopters are getting cited more often in AI-generated answers.
Will more free tools be added?
Yes. An AI Visibility Checker and Hreflang Generator are already in the roadmap. Follow the changelog to see what ships next.
What happens if I want more than the free tools?
The full SEOcrawl platform includes continuous monitoring, rank tracking, AI visibility across ChatGPT, Claude, Perplexity, and Gemini, a GSC connector, and automated alerts. 14-day free trial, no credit card.
