Regex Hero Professional is Now Free

Regex Hero is now completely free!  I've been working on this tool off and on for the past 8 years. I spent a lot of time making it very powerful and easy for developers to create efficient regular expressions. Throughout most of this time it's been a paid product. However, with the added pressure of other free tools out there getting better all the time, I've finally decided to make Regex Hero free as well. Enjoy! Try Regex Hero at http://regexhero.net/tester/
