According to this forum description this is the place to post announcements about regex tools. Hopefully I have understood the topic correct :-)
I have recently released a beta of my regex tool at http://regex.larsolavtorvik.com/. So far it supports PHP PCRE, PHP POSIX, JavaScript, Perl and Python. I plan to add more languages in the future if there is a demand. Feel free to drop by and test it and give me feedback on my blog (http://larsolavtorvik.com/) about bugs, feature requests and other things.
Hopefully it can be usefull for you!
