After teasing a free version of Appmethod at AnDevCon last week, Embarcadero released a new version of Appmethod today, which includes the "Free Forever" SKU. The download link and FAQ are available on the pricing page.
While the previous version was based on XE5, the new one is based on Rad Studio XE6, Update 1, which was also released today.
I was hoping that the free version would include Delphi. Sadly (for me), it seems that only C++ is supported.
If you want to take a look at what's new, including the free version, Embarcadero has a webinar on June 25th.
