From a URL to every layout bug, on every screen, with the fix. Then the follow-up until it’s really fixed.

What it finds

The layout bugs clients notice first

Every check runs in a real browser and shows each problem on a screenshot, with what to fix.

Responsive bugs

Sideways scrolling, cut-off text, overlaps, uneven padding, tiny tap targets and broken forms.

Breakpoint sweep

Every width from 320 to 1920px, so a layout that only breaks at 853px can’t hide.

Figma comparison

Fonts, colours, spacing and missing text compared with the approved design.

Live site on every screen

Click, scroll and type on the real site in four sizes at once, mirrored across all of them.

Reports your client can read

Plain-language fixes, a share link that needs no login, PDF and Excel exports.

Cross-browser testing

The same checks in Chrome, Safari and Firefox, so you catch the Safari-only bugs clients find on their iPhones.

Mark it and move on

Intentional? Mark it by design. Fixed? UICheck checks the page again and confirms it, or flags it again. Select many and do it in one go.

See what changed since you approved it

Approve how a project looks; every later run shows what moved, grew or disappeared, side by side.

QA as a team

Shared projects, roles and an activity log. Clients join free to comment and approve.

Every deploy, checked

One step in GitHub Actions, GitLab or Bitbucket. The build fails when a deploy breaks the layout.

Review it like a prototype

The site on phone, tablet and desktop side by side. Click through it; every page you open is checked, with problems marked on the page.

Client feedback, one To fix list

Clients comment on the page and approve it; visitors report from the live site with a picture or a recording. It all sits with the bugs UICheck finds.

Know when a page changes

Monitoring checks your pages daily or every 6 hours and tells you when text, look or problems change, with before and after.

In every check

More than a quick screenshot

One check covers what a tester would spend an afternoon clicking through.

Integrations

Follow up every bug until it’s fixed

Send one finding, or fifty at once, to Linear, Jira, GitHub or Worksynk with the screenshot and the fix. Each site goes to its own project. When the task is closed there, UICheck checks the page again and tells you whether it’s really gone.

  1. Step 1

    Send it

    One click creates the issue, or select many and send them together. No screenshots to copy.

  2. Step 2

    Track it

    The finding keeps a link to its issue, so everyone sees it’s being handled. Sent to the wrong place? Remove the link and send it again.

  3. Step 3

    Confirm the fix

    Closed in the tracker? UICheck re-checks the page at the sizes it broke and emails whether it’s fixed or still there. Monitoring catches it if it ever comes back.

Fix verification

“Fixed” means fixed. UICheck checks.

No more “can you look again?”. The moment a bug is marked fixed, here or in your tracker, UICheck re-checks that page and tells you whether it really is.

  1. Someone says it’s fixed

    Mark a finding fixed, resolve a comment, or just close the task in Linear, Jira, GitHub or Worksynk.

  2. UICheck checks again, by itself

    That page is re-checked at the screen sizes where it broke. It doesn’t use your daily checks (Lens and Prism).

  3. Before and now, side by side

    Gone? The fix is confirmed. Still there? It’s reopened. Comments show their spot then and now, ready to confirm.

  4. One email with the answer

    Whoever marked it, or made the task, hears what’s fixed and what’s still there, with a link to the report.

How fix verification works

How it works

From URL to fix list in three steps

No install, no scripts. A free account and a public URL is all it takes.

FAQ

Questions, answered

What does UICheck test?

UICheck loads your page on up to 7 screen sizes, from a 360px phone to Full HD, and checks for horizontal overflow, spacing and alignment problems, cut-off or tiny text, overlapping elements, small tap targets, form field issues, broken images, JavaScript errors and accessibility (WCAG) problems.

Is UICheck free?

Yes. A free account gets 5 checks every day on 5 common screen sizes, one saved project and checks from CI. No card is needed. Lens adds every screen size, Safari and Firefox, full-site checks, Figma comparison and visual baselines; Prism adds a team of 5, unlimited checks and the live site.

Does it work with WordPress, Next.js or Shopify?

Yes. UICheck tests the rendered page in a real browser, so it works with any platform or framework, including WordPress, Next.js, React, Angular, Shopify, Webflow and plain HTML.

Do I need to install anything?

No. Create a free account, paste a public URL and run the check in your browser. Teams can also run it from CI before every release.

Can I share results with my developer or client?

Yes. Make a report public with a private share link that works without an account, or download it as a PDF book or an Excel sheet with a screenshot of every issue.

Can my team use UICheck together?

Yes, on Prism: invite up to 5 people into one workspace (more for $10 a month each) and clients as free read-only viewers. Everyone shares the projects, checks and integrations, and the activity log shows who did what.

What if an issue is intentional?

Mark it as “by design” and UICheck stops counting it on that page in future checks. Mark real problems as fixed, or close their task in your tracker: UICheck checks the page again (on Lens and Prism right away, on Free with your next check), confirms the fix or flags it again, and emails you the result.
