# Is there an easy resource to find and compare version differences? Throughout the whole time we used Vaadin, we could not find a clear resource that just laid out the major differences. We would have to find articales posted about the updates and then read through multiple forum posts to kind of piece together what was really going on with each update. On top of figuring out if we upgraded, what all we would break in the process and then how to fix it. It was a migraine to say the least. ##### Post Metadata - Net upvotes: 1

# Why are people calling Vaadin a high cost solution? I have been considering using the free version to port 4 games written entirely in Java to Progressive Web Apps to reach customers on Windows, Macintosh, Android, and iOS. Would the free version be insufficient to accomplish my goals? Is the free version ever not free? Is the process as seamless as it sounds? As a developer, I suspect that it isn't seamless. I'd appreciate hearing a response from anyone who can give me an idea of how much work might be involved. Any comparisons to TeaVM, CheerpJ etc would be appreciated as well? ##### Post Metadata - Net upvotes: 1

# Do you feel that the documentation of Vaadin is lacking? At the vaadin website I feel at odds with the documentation of its components API's or its classes API's and also it is very difficult to get insights into vaadins abstraction. How do you overcome this problem? ##### Post Metadata
