This program works in several browsers (chrome, firefox) without any problems and it's free! It has helped me with my work as SEO Analyst at an online portal. The only thing I dislike about this software is its interface. Sometimes you need to click multiple times before getting what you want and sometimes some options are difficult to find. But overall everything seems fine for now, so no complaints. We use this software to monitor our web pages from time to time, especially when we have something new out there. If you're looking for some help with your web monitoring or if you just like graphs and data visualization, this one will do the trick!
