Purpose and Context

Sustainable Softworks is a Macintosh software developer inspired by building tools to make technology more accessible and improve the Mac user experience.

The company was founded in 1996 by Peter Sichel to build a software IP router for the Mac, and was instrumental in ushering in the era of reliable network connectivity and Internet sharing with IPNetRouter (NAT router), IPNetMonitor (network diagnostic toolkit), and IPNetTuner (TCP/IP tuner for improving network performance and compatibility). IPNetRouter received a 1999 Macworld Editor's Choice Award for Best Network Utility and was licensed to Apple Computer as part of the original AirPort Software Base Station.

Sustainable Softworks' dedication to customer support and continuous improvement has attracted many delighted customers as it adds new products and features to extend the Mac in areas that have otherwise been neglected.
