Frequently Asked Questions

1Are these technical SEO tools free?

Yes. Every tool is free, needs no signup, and has no usage limits.

2Do the tools crawl or fetch my website?

No. You paste your file, list or tags and everything is checked inside your browser. That also means the tools work on staging sites that are not public yet.

3Is my data safe?

Yes. Nothing you paste is uploaded or stored. URLs, robots.txt files and sitemaps stay on your device.
