We make software that measures how good websites are, and how to make them better.

This sounds simple, but it masks a tonne of interesting problems that we solve every day. How does a computer determine what is ‘good’? How do we keep up with the constantly changing nature of the Internet? How do we test millions of pages globally every day as efficiently as possible?

Our clients include household names and over a thousand small businesses. For the first ten years of our life we used to be successful web designers, but two years ago we gave that up to make our own products. Since then we’ve been doing pretty great.


We make two tools for testing websites: Sitebeam (the paid one) and Nibbler (the free one). We have some ludicrously exciting things planned for 2014, but for now our plans for world domination must remain a secret.
