Is the website checker free?

Yes. Scanning a site is the free front door: point the checker at any URL and get status, title, H1, canonical, and broken-link results. The paid side of Mira goes deeper — it learns your critical journeys and re-tests them after every change.

What does a website check cover?

A scan reports the essentials: HTTP status of the URL, page title, H1, canonical tag, and broken links across internal and external links, including 404s and redirect loops.

When should I check my website after a change?

After every deploy or content publish. Most changes are safe, but the failures are quiet: a link that 404s after a migration, a form that silently stops submitting, a canonical that points at the wrong page. A scan right after the change catches those before customers do.

Do checks run without breaking GDPR?

Yes. Mira keeps product-data processing and AI execution on its own EU infrastructure and never trains models on customer data. Your site content, screenshots, and test data stay on Mira-operated servers in the EU.

Free Tool · Website Checks After Every Change

Check your website after every change

Point a website scanner at your URL and get the essentials back in one report: HTTP status, page title, H1, canonical, and broken links. Run it after every deploy or content publish — before a quiet regression turns into a customer complaint.

The scan is the free front door. When a site needs more than the essentials — forms tested, journeys walked, layouts compared against the last known-good state — Mira Checks runs the deeper checks after every change automatically.

What a scan reports

Five essentials, one pass. Each answers a specific question about whether the change you just shipped is actually fine.

Sample scan output All checks passed

URL: https://example.com
HTTP status: 200 OK
Page title: Example — A website for your business
H1: Welcome to Example
Canonical: https://example.com/
Broken links: 0 of 124 links

HTTP status

Is the page actually reachable? 404, 500, redirect loops and mixed-content issues surface here.

Title, H1, canonical

Search favourability basics: does the page still title itself, name one message, and point search engines at the right URL after the change?

Broken links

A crawl of internal and external links flags 404s and redirect loops — the classic silent regression of a content migration or slug change.

Why scan after every change

Deploys touch code, config, and content — usually all three. Most changes are fine. The rest fail quietly, and a 30-second scan is the cheapest way to find out which kind you shipped.

Free, no setup
Enter a URL, get the report. No account, no script, nothing to install — it works from any device.
Catches silent regressions
Broken links and wrong canonicals don't crash anything — they just cost you visitors and rankings until someone notices.
The front door to deeper checks
Essentials first. When your site matters enough to re-test forms and journeys after every change, Mira automates that too.

A scan right after the change catches those before customers do.
How is this different from testing after a deploy?: The website checker is a quick scan of a single URL — status, metadata, links. Post-deploy testing is the fuller discipline: forms, journeys, console errors, and visual snapshots across your whole site. See the post-deploy view.
Do checks run without breaking GDPR?: Yes. Mira keeps product-data processing and AI execution on its own EU infrastructure and never trains models on customer data. Your site content, screenshots, and test data stay on Mira-operated servers in the EU.
