OUR VALUES

What we hold ourselves to

Six things that shape every tool we build, not just what we say on this page.

Transparency

No hidden charges, no login walls, and no surprise upsells.

Speed

Most scans finish in seconds, and even the full site audit takes about a minute.

Privacy

We do not collect or save any URLs or scan data. What you scan stays yours.

Accuracy

Every check is built to catch the common technical, SEO and security problems that actually cost sites traffic, and each result tells you how to fix it.

No Signup

Every tool and both extensions work the moment you land on the page, no account, ever.

Works Everywhere

WordPress, Shopify, React or static HTML: if it has a URL, our tools can check it.

OUR STORY

How SiteAuditHub came together

From a single script to a full toolkit, built one tool at a time, based on what site owners kept asking for.

1

It started with one problem

A simple broken-link scanner, built to solve one recurring headache: finding dead pages before visitors did.

2

The toolkit grew

SEO, redirects, malware, hidden elements and sitemaps followed, each one added because someone asked for it.

3

Now: 15 tools, 2 extensions

What began as one script is now a full audit system, used for thousands of scans every month, still free, still no signup.

CHROME EXTENSIONS

We also live in your browser

Some checks are easier to run right on the page you're looking at, instead of pasting a URL into a separate tab. That's what these two extensions are for, same audit logic, one click away.
