HOW IT WORKS

Three steps. No account.

Most audit tools make you sign up before showing a single result. Ours doesn't. Paste a URL, wait a few seconds, and read a report written in plain English, not a wall of technical jargon only an engineer could love.

1

Paste your URL

Drop in any web page, yours or a client's. Nothing to install.

2

We scan your pages

Our crawler checks your page and the internal pages linked from it against 10+ audit rules.

3

Get a fix-it report

A plain-English list of what's broken, ranked by priority.

SITE HEALTH TOOLS

Run each check separately or work through them like a pre-launch list.

CHROME EXTENSIONS

Take the audit into 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, wherever you're browsing.

BUILT FOR DEVELOPERS

Works with whatever you're already building

SiteAuditHub doesn't care what your site is built on. Point any tool at any URL, WordPress, Shopify, a static site, a React app, and get the same clean, honest report every time.

No API key required

Every tool works from a plain URL. Nothing to configure, no key to generate, no rate-limit dashboard to babysit before your first scan.

Readable output

Reports are structured so they're easy to scan visually or hand straight to a client, not raw JSON you have to format yourself.

Built with the same tools you use

The Chrome extensions run entirely in the browser. No server round-trip for things like color picking or font inspection.

THE OUTPUT

Every scan ends in one clear number

Dozens of technical checks, boiled down to a score and a ranked list of fixes.

WHY SITEAUDITHUB

Built to be used, not signed up for

We built SiteAuditHub because most "free" audit tools aren't really free, they ask for an email, a login, or a card before showing a single result. Ours doesn't, and that's on purpose.

Fast by default

Most scans return a full report in seconds. We don't queue your request behind a paywall or a waitlist, you paste a URL and the crawler starts immediately.

Nothing stored, nothing tracked

We don't create an account for you, we don't keep your scan history on our servers, and we don't email you about it later. The URL is fetched, analyzed, and forgotten.

Written for humans, not crawlers

Every report explains what's wrong in plain English and tells you what to fix first, not a raw dump of technical flags only a developer could decode.

One toolkit, not a dozen tabs

SEO, links, redirects, security, schema, headers, sitemaps and images, every tool shares the same design and the same report format, so nothing feels bolted on.
