Forio Broadcast is a free service that allows you to create and host simulations online.

"Forio Broadcast provides everything you need to get a simulation running on the web." (Developer statement)

If you don't want to start from scratch, you can select a simulation model from the Forio library (e.g. "Epidemics", a model that simulates how a disease spreads through a population) and modify it according to your needs.

Alternatively you can import a model from another simulation software and build upon it. For the interface, you can also either select a premade one (and modify it if you want) or create your own one by coding it with HTML code.

When you sign up for your free account, a Web page for your simulation is created automatically. Everyone can access your simulation on the Web and you are provided with some basic usage statistics.

Forio Broadcast is easy to access and a set of well designed Wizards ensures that all of the basic features can be implemented in a guided and intuitive way. However, if you want to build a unique, customized simulation you need to be able to use the Forio equation language and/or HTML.

If you do not already have this knowledge, but are willing to acquire it, you are supported by Forio with detailed instructions and useful links to external learning resources (e.g. for HTML writing at:
http://www.pageresource.com/ html/index.html).

On the Forio Website you can also read articles on simulation (http://www.forio.com/ resources.htm) and get inspired by existing simulations
(http://www.forio.com/cgi-bin/ simcat/dclinks.cgi?action= view_ category& category=Simulation).

Be aware, that you can only host one simulation at a time since you are provided with just one web page in your free account.

If you want to get a whole domain to run different simulations or if you want to restrict access to your simulation, you have to sign up for a professional account ($350/month)(more info at:
