Check every page of your website before launch.
Bugs hide on the pages nobody opens before launch. Paste the home page: UICheck finds your pages, tests each one on every screen size in Chrome, Safari or Firefox, and emails you one report.

Finding your pages
It finds the pages you forgot to test
<url>
<loc>/services</loc>
</url>01Sitemap first
Pages listed in sitemap.xml are queued first, so the pages you care about are checked even on large sites.
/blog → /blog/launch-checklist
/about → /careers02Then your links
Links on your pages fill in what the sitemap misses: blog posts, landing pages, forms.
✓ northwind.studio/contact
✕ instagram.com/northwind03Never off your site
Only your own domain is checked. Social links, payment pages and other sites are skipped.

Questions
How does UICheck find my pages?
It reads your sitemap first, then follows links from your pages. It never leaves your domain, so third-party pages are not checked.
How many pages can I check?
Lens checks up to 15 pages and Prism up to 50 in one check. Free checks one page at a time.
How long does it take?
A few minutes for most sites, depending on the number of pages and screen sizes. You can close the tab; we email you when the report is ready.
Can I check the whole site in Safari or Firefox?
Yes. Pick the browser when you start the check and every page is tested in it.
Does the breakpoint sweep run on every page?
It runs on the first 10 pages of a full-site check, after the screen sizes.
Can I hand the report to a client?
Yes. Share a read-only link, or export a PDF or Excel report with plain-language fixes. On Prism the exports can carry your agency’s logo and colours.
Test the pages nobody opens before launch
Lens is $5 a month: full-site checks up to 15 pages, every screen size, Safari and Firefox.
