About
No account, no analytics, no catch worth hiding
There is a commercial reason this exists, and it is better to state it than to make you wonder what it is.
What this is
5 free tools for SEO and AI-visibility work, running entirely in your browser, published by Visibility100x and hosted on GitHub Pages. The source is one public repository under the MIT licence. Fork it, host it yourself, strip our name off it — that is what the licence permits and we mean it.
What it collects
Nothing. There is no analytics script, no tag manager, no error reporter, no cookie, no local storage, and no font or stylesheet loaded from anyone else's domain. The typeface files are served from this repository for exactly that reason: a page whose argument is that your data stays put should not be making a request to a font CDN on every visit.
You do not have to believe any of that. The meter in the header counts every fetch, XHR and beacon the page makes after it loads, and it reads zero on every page. Open the network tab and check it, or disconnect and keep working — the tools do not notice.
GitHub serves the files and, like any web host, sees the request. We have no access to those logs and no way to associate them with anything. That is the honest boundary of the claim: we collect nothing, and the host does what hosts do.
How it is paid for
By the main site. Visibility100x sells a managed AI-visibility service and a subscription product, and this site exists partly because it is genuinely useful and partly because some of the people who find it useful will later need something that needs a server behind it. That is the whole funnel, and it does not require your email address to work.
Nothing here is crippled to sell an upgrade. There is no row limit, no watermark on the exports and no locked feature. If a tool could reasonably do something in a browser, it does it.
Why it is a separate site
Because github.io is on the Public Suffix List, which means search engines treat this address as its own site rather than as part of visibility100x.com. It builds its own reputation and lends the main site nothing automatically. The upside of that separation is the part that matters: these pages are written here, for the jobs the main site does not cover, so neither site is competing with a near-copy of itself.
The checkers page explains the technical half of the split — why the URL-fetching tools cannot run on a static host, and what to use instead.
Corrections
These tools embed opinions about click-through rates, truncation widths and how much of the web serves a real llms.txt. Some of those numbers will drift and some may simply be wrong. If you can show that one is, we would rather fix it than defend it: open an issue on the repository or write tohello@visibility100x.com.
