Free website tool

Find the bugs your visitors hit before they leave

The Website Bug Checker is a free tool from Ergora for small business owners that opens your site in a real browser on a laptop and a phone and lists what is broken or slow in plain English.

Enter your website and a real browser visits it like a first-time customer, on a laptop and a phone. In about a minute you get a plain-English list of what is broken, what is slow and what to fix first.

Free, no sign-up. Read-only: we visit public pages and never fill in forms.

What this checks

  • JavaScript errors that can break buttons, menus and forms
  • Your own scripts, styles, images and fonts that fail to load
  • Links on your homepage that lead to error pages
  • Phone layout: sideways scrolling, missing mobile setup and buttons too small to tap
  • How long the main content takes to appear (Largest Contentful Paint)
  • Serious accessibility problems found by axe-core, plus unlabelled form fields and nameless buttons
  • Insecure files on secure pages and certificate problems

Most visitors never tell you something is broken

A checkout button that does nothing or a menu that will not open on a phone does not send you an error report. People just leave. Testing the way a stranger arrives catches the problems you stopped noticing because you always use the site the same way.

Read-only, so it is safe on a live site

The checker only looks. It loads up to five public pages, never fills in or submits forms, never logs in and never places orders. It runs in a sealed browser with no access to anything private.

Questions

What pages does it check?

Your homepage on a laptop and a phone, then up to four key pages it finds in your navigation, such as pricing, products, contact and sign-up. It also checks up to 25 of the links on your homepage.

Does it test my checkout or sign-up form?

It opens those pages and checks them for errors, but it never types into forms or submits them, so it cannot create fake accounts, orders or enquiries on your site.

Why is the speed result different from PageSpeed Insights?

This check loads your site once, through a real browser on one of our servers, so timings vary with network conditions. Use it to spot pages that are clearly slow, and PageSpeed Insights for a repeatable lab score.

How often can I run it?

Each site gets one fresh scan a day. Running it again the same day shows the same report, which keeps the checker quick for everyone.

How do I fix what it finds?

Every issue comes with a plain-English fix you can pass to whoever looks after your site. Most fall into a few groups: a broken plugin or tracking script, missing files after a redesign, old links, and theme settings for phones.

Is anything stored?

The report is kept for seven days so the link keeps working, then deleted. The screenshots show only your public pages.

Developer pack

Want this done for you, continuously?

A one-off scan shows today's problems. In Ergora the developer specialist keeps watch on your site, ties errors to the deploy that caused them, and tracks each fix in the repo and issue tracker you already use.
