I am pretty sure that he is using dotnetnuke. There is some custom programming that has been implemented also, but there are a number of plugins available to make it pretty much what you want it to be. It is an easy install and can be hosted really easy by some providers. I can recommend PowerDNN.com. They are really easy to work with.

DJ mentioned in the past that the website is all bespoke and custom made. By building a website from scratch you can be pretty sure it wont fall foul to many of the usual security flaws associated with other, pre-made backends such as wordpress, phpbb etc.

That said, I always use pre-made backends now. They are easier and faster to set up, security is pretty good and they do the job. Some, such as Wordpress, have a huge community also which always helps.

Thank you for the compliments

The website is entirely custom with no third party components, not that anyone wanting to develop their own wants to hear that, ha. I started making my own "blogging" software for my personal website in 2006 and the ez-robot website is a branch of that. The back end is .Net 4.5 and the database is MySql.

As for the html, it was modified to be "responsive" by our talented ex-employee Chrissi.

I've always been the main developer at ez-robot, and that includes both the website and ARC software, mobile apps, firmware, etc..

If you're looking at making a website - the number of features which we provide are custom and therefore a little difficult and expensive to have programmed. I would recommend starting with limited features, such as an online store. I don't know what web framework is available, so i'm not going to be very useful for recommendations. If you are hoping to have many tutorials and information, ensure the framework that you select is the easiest to edit and manage
