About

This is still a work-in-progress, but it is made available since it is already helpful in debugging your regexes.

It is intended for (currently a subset of) .NET regexes, but it might work for other types of regexes, if no type specific constructs are used.

It is a first of its kind tool for debugging regexes, and we hope you will find it useful.
