Browser Compatibility Report
Get a quick report of how your pages perform on each tested browser. With this report you'll never have to manually compare screenshots to look for rendering problems again. A green check mark means everything is good. A red cross means you should dig in further. Don't worry, we have more information as you drill down! Check out all of our Comparison Tool features for more information.
Comparison Tool: Drill-down Error Display
See each issue as it appears in your reference browser and where it appears broken in the tested browser. We give you as much information as possible, including CSS selector and element positions, to help your Web team find and fix the problem.
Comparison Tool: Side-By-Side View
Compare your page in two different browsers side-by-side.
Comparison Tool: Overlay View
View your page in two different browsers on top of each other. You can use the slide bar to fade between the two browsers.
Comparison Tool: Thumbnail View
Get a quick view of how your page looks (above-the-fold) in all of the different browsers at once.
Additional Image Features
- Quickly view larger image sizes by hovering over the thumbnail and choosing to either enlarge the thumbnail screenshot or view the full canvas screenshot.
Easily integrate with your existing testing and deployment tools using our ReST API.
Quickly learn about any site problems that could be affecting the way your site performs. With our Problems Report you'll be able to find problems with your site before your customers do. Read on for a brief description of all the problems we catch and how they can affect your site.
- HTML and CSS validation errors and warnings may unexpectedly change the way some browsers render your page. We'll give you a quick breakdown of how many errors and warnings are in your HTML and CSS files. You can dig into these issues even further with our Code Analysis feature.
- Making sure your site visitors can access all of the pages they're supposed to be able to is always a good thing. Unfortunately, sometimes server configurations get mangled and a public resource all of a sudden becomes password-protected. We'll let you know which pages require authentication and which ones are marked as forbidden when logged in.
- Few things are more annoying to a customer than a link that goes nowhere. As we test your site we'll check that all pages return something more useful than a Page Not Found message.
- Server errors in the 500 range indicate a serious server-side problem. We'll let you know which pages are raising these errors so you can dig in and fix them.
Empty Content Warnings
- Fetching a resource that has no content is an unnecessary performance hit. We'll alert you to any items we encounter with a zero length so you can either fix the resource or remove the link, speeding up your site for your visitors.
- Redirects, when done improperly, can be both a major usability and a major SEO problem. As we encounter redirects we follow the chain and show you what that looks like. Moreover, we show you the type of redirect (301 vs. 302) that we encounter each step along the way. This is a great way to get a snapshot of what your site is really doing.
We validate your HTML and CSS, with support for browser-specific extensions and inline errors so you can find and fix problems quickly.
We support both HTTP Basic and cookie-based login systems, so you can index and test protected content.
We track changes to your site as you run new tests, showing you how your code quality and UI change over time.
