# What is this web application built with?

This demo ([demo.techsoft3d.com](http://demo.techsoft3d.com/)) was built using the HOOPS Web Platform. The frontend UI comes from [Sanna](http://www.sanna.io/), a design firm that we partner with. The graphics are the web viewer from [HOOPS Communicator](https://www.techsoft3d.com/products/hoops/communicator/). The conversion service of HOOPS Communicator, powered by [HOOPS Exchange](https://www.techsoft3d.com/products/hoops/exchange/) to read CAD data, is also hosted on an AWS elastic beanstalk server. This allows you to upload CAD files and view them.
