Great resource

I often refer others to this site for testing their regular expressions or learning a bit more about how the engine parses them. The site is user-friendly,with no intrusive advertising and the tools work reliably. I have similar tools bookmarked, but this is the only one I'm aware of that also parses the Python, Go, and Java flavours of regex (as well as PCRE & ECMA). It doesn't currently support the .NET/Perl 5 flavour, and I'd love to see this added in future. However, as far as free dev tools go, this is a must in your bookmarks if you work with regex.
