Social network is important, especially facebook, IAP. We need revenue (to buy coffee and continue to work )
As an indie developer, I won’t consider EziSocial due to limited budget/feature. \$50 should be spent on other areas and not on the social network for single app, which could be terminated anytime because no one download/play the app.
Soomla looks good but does not support 3.x yet.
Avalon is free and you may get a trial.
Anyway I don’t think it is possible to debug/work on my development environment for those API because we are using Windows 7.
