Run any of these tools against your own page — or a competitor's — to preview search results, audit meta tags, render social cards, and check your sitemap and robots.txt. No signup, no extension, no API key.

Audit every meta tag on a page: title, description, robots, canonical, Open Graph, Twitter Card, hreflang, and more.
Open Graph Preview

Sitemap & Robots.txt Checker
/tools/sitemap-checker
Fetch and validate /sitemap.xml and /robots.txt, surface URL counts, lastmod, and any parser errors.
Submit your SaaS

After you audit your page, list it on ListMySaaS to get a dofollow backlink, a verified badge, and a profile page indexed by Google.
Why we built these
ListMySaaS is a free directory for SaaS founders. Most founders we talk to don't have an SEO stack on day one — they have a Notion checklist and good intentions. These tools cover the five checks we run on every listing before it goes live: does the title fit in Google, are the meta tags complete, do social cards render, is the heading structure sound, and can Google actually find the sitemap. Run them on your own listing or your own homepage to see how you score.
FAQ
- Are these SEO tools really free?
- Yes — every tool is free, requires no signup, and runs on demand from your browser. We do not log the URLs you submit.
- Do I need to give you access to my site?
- No. You paste a public URL; we fetch the public HTML the same way a search engine crawler would. You never share credentials.
- Can I use these tools on any website?
- Yes — any public http(s) URL. We refuse to fetch private or internal addresses for security reasons.
