HUBzero™ is a platform used to create dynamic web sites for scientific research and educational activities. With HUBzero, you can easily publish your research software and related educational materials on the web.

A hub combines unique middleware with Web 2.0 functionality, providing a platform that is much more powerful than an ordinary website. Users will not only be able to network and share information, but also create, publish and access interactive visualization tools powered by a rendering farm and other cluster computing resources, as well as engage in online collaboration fostering the development of an educational community. HUBzero was created by the NSF-funded Network for Computational Nanotechnology starting in 2002 with the development of their hub at Since then, usage of has grown exponentially. In 2009, served 274,000 visitors from 172 countries worldwide. Of these, a core audience of more than 100,000 users watched seminars, downloaded podcasts and other educational materials, and accessed more than 160 nanotechnology simulation tools. While accessing the tools, users launched a total of 369,000 simulation runs via their web browser and spent 7,286 days collectively interacting with tools and plotting results. To date, there are more than 430 citations to, its simulation tools, and other resources, in academic literature.

In 2007, HUBzero was spun out from as a separate project and software package to power new hubs. The first three were,, and, commissioned as NSF engineering virtual organizations (EVOs). Today, HUBzero supports more than 20 hubs with a combined audience of 380,000 visitors each year. One of these, the NSF Network for Earthquake Engineering Simulation (NEES), a $105M award connecting 14 institutions, is a particularly large project using the HUBzero platform not only for simulation, but also for experimental data collection. Communities can rely on HUBzero: uptime for in the most recent year was 99.8% and has been above 99% for the past four years.
