How do I test my website after a deploy?

Run the checks that catch the regressions deploys cause: load key pages, submit every form, walk critical journeys, verify links, watch for console errors, and compare visual snapshots against the last known-good state. Mira Checks runs this checklist automatically after every change — no scripts, no recordings.

What is post-deploy testing vs continuous monitoring?

Post-deploy testing verifies a specific change right after it ships — did this deploy break anything? Continuous monitoring runs the same checks on a schedule in between deployments, so regressions from third-party changes or infrastructure drift are caught too. Mira does both from one setup.

How fast does Mira Checks find regressions?

Mira learns your site and its critical journeys up front, so a post-deploy run typically returns a pass or fail result within minutes — with visible evidence your team can act on before customers find the problem.

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.

What checks should run after every change?

At minimum: links resolve, forms submit, requests and API calls succeed, the console stays free of errors, layouts match the known-good state, and checkout or booking journeys complete end to end. That mapping — scenario to the check that catches it — is exactly what Mira automates after every deploy.

Website QA · After Every Change

Test your website after every deploy

Every deployment is a small bet that nothing you didn't touch also changed. Most of the time it pays off — but the failures are quiet: a form that no longer submits, a checkout step that 500s on mobile, a link that 404s after a content migration.

Mira Checks re-runs your post-deployment checklist automatically: broken links, forms, requests, console errors, layout regressions, and checkout or booking flows — caught within minutes of the change, with visible evidence.

What can break after a deploy — and the check that catches it

A deployment touches code, config, content, or all three. Each failure mode maps to one check. Run them all, and the silent regressions stop being silent. To spot-check a single URL before committing to the full pass, start with the free website checker.

Broken links and 404s after a migration or slug change	Link check: crawl the site's internal and external links, flag 404s and redirect loops.	change validation
Forms that silently stop submitting	Form check: submit contact, lead, and newsletter forms end to end; verify the confirmation and where the data lands.	change validation
Failed requests and API errors on key pages	Request check: validate the HTTP status of every loaded resource and capture failing API calls.	scheduled monitoring
Console errors that break interactions	Console check: capture JavaScript errors on every page load during the run.	CMS testing
Layout regressions, shifted elements, missing assets	Visual snapshot check: compare key pages against the last known-good screenshot.	CMS testing
Checkout or booking flows failing mid-step	Journey test: run the full flow to the business result — purchase or reservation confirmed.	checkout testing · booking testing

The checklist after every change

A thorough post-deploy pass covers six things. Done manually it takes 30–60 minutes per release and depends on someone remembering every critical path — which is exactly when it gets skipped. That risk grows when the code itself is generated: the guide to testing AI-generated code explains why a clean diff does not prove a working site.

Load key pages
Homepage, landing pages, and everything this deploy touched.
Submit every form
Confirm submissions succeed and the confirmation fires.
Walk critical journeys
Checkout, booking, signup — on desktop and mobile.
Check links and console
404s, broken anchors, and JavaScript errors.
Compare snapshots
Layout shifts and missing assets against known-good. WordPress sites shift most often after theme and plugin updates, so the WordPress visual regression testing guide covers what to compare.
Verify third-party scripts
Tracking, chat widgets, payment embeds still load.

How Mira runs this checklist after every change

Mira learns your site's pages and critical journeys, then re-runs the whole mapping above automatically after every change: submitting forms, walking journeys, comparing against the last known-good state for visual regressions. No scripts, no recordings, no test maintenance.

Learns your site automatically

Discovers pages, recognises forms, and learns critical journeys without configuration.

Runs after every change

Re-checks the journeys your business depends on whenever you deploy or publish a change.

Keeps watching between deploys

Third-party changes and infrastructure drift can break a site with no deploy at all — continuous checks catch those too.
