Do you ever want to check a successful competitor’s websites to see where you can do better yourself?   Do you come across websites you like and wonder which theme it uses or what code or plugins achieve certain features? Would you like to look behind the scene to use the same on your own site?

Here are some web resources to help you do this easily (without any coding knowledge).

Check Competitors Themes

WP Theme Detector

If you come across a WordPress theme you’d like to use yourself, type it’s url at WP Theme Director and you’ll find out what it is.

What Software Does That Site Run On?

Although WordPress is the most popular software for blogs, websites are powered by many different kinds of platforms and scripts.


Wappalyzer is a browser extension that can find many blog and content management systems, eCommerce platforms, web servers, JavaScript frameworks and analytics tools. Here’s a list of what it can find. (Note: some of the scripts might be used by the web server and not installed by the website owner.)

What Color is That?

Do you like a particular color or the color scheme used by a website?

Upload any image to Pictaculous and this web-based tool will tell you which colors the image uses and suggests color palettes to match.

If you prefer to use downloadable software the post Best Color Tools For Web Designers gives you a good selection to choose from. I use a little software tool called MWSnap which captures parts of pages as images and includes a color tool and ruler.

Scrapbook Add-On for Firefox

With Scrapbook you can download individual webpages and pages linked to them. You can choose what type of files to include in the download (images, sound, movies, pdf, javascript …).

A sidebar list gives you links to pages you’ve downloaded allowing you to view them in your browser or access the files for editing. While viewing a downloaded page a bottom toolbar appears containing editing tools allowing you to erase parts of a page you don’t want, to highlight areas and then re-save.

It’s useful for keeping copies of pages you want to view again or to download a page full of free images.


Microsoft OneNote is my constant companion while browsing, for taking copies of snippets of information. Anything you copy and paste into OneNote includes the link to the page you copied it from. I’ve written detailed posts about OneNote starting with Productivity with OneNote.

Check Competitors website code

I won’t go into detail about this but as a web developer I find them really useful especially for problem solving. When I first started web building they were invaluable as learning tools.

Scrapbook as mentioned above

As well as a download tool, Scrapbook is excellent for checking html and CSS code.

Last but by no means least comes Nibbler. Enter an address of a competitor and it will score it out of 10 for key areas such as SEO, social media popularity, accessibility, and validity. Here’s a screenshot of the results for Social Media Examiner:

Each of the elements on the right come with details.

Now I need to go back over this post and add some keywords so that this posts scores well with some of these tools. Out go some of the catchy titles and in comes some repetition.

There are many more tools available but I only recommend those I’ve used myself. If you can recommend any others please let us know by leaving a comment.
