There are two ways we can understand the word demo in the IT development. It may be a meeting with the team and the stakeholders to review the sprint in the Scrum methodology. It may also be understood as an example of the product given to a potential customer to attract their attention and check if they need the product and ready to pay for it. In both meanings we talk about some small result of the development process that is used as an example and that can show what the future solution will be capable of.  

Using demos in the development process is an effective idea for several reasons: 

* customers see the future product, they know what to expect; 
* the time for the design customization is saved; 
* demos teach customers how to interact with the future application. 

In this review, we will focus on the most common types of web apps and resources to find suitable demos for them.
