Niche Software

Welcome to Niche Software, a MicroISV based in Wellington, New Zealand.

The primary goal of the site is as a host to my writing - mostly entries in my blog, but also including more detailed articles and the occasional highly opinionated editorial. A secondary, but still important, goal is to be a place to post some tools, utilities and toys that I have written. As I tend to develop applications that "scratch my own itch," most of these are fairly technical in nature. Please check out the license on any item you download - while many are free, some are not.
