About the developer

Checkbot was developed by freelance app developer Sean Wilson from Edinburgh, UK . While working as a consultant on web projects over several years, Sean built up a collection of small tools to automate away tedious and unreliable manual testing that had to be done day-to-day to identify and fix website issues. These tools were eventually combined and expanded upon to create the Checkbot browser extension. Checkbot aims to be a comprehensive and user-friendly web development tool that makes it easy to follow current SEO, speed and security best practices for websites.
