We just opened out our new cloud version and as part of that move we have started our journey towards open sourcing too. Mowbly has six different modules and we are open sourcing two of them the cross platform mobile SDK (iOS & Android) and coming up in May we will open source our cross platform mobile UI framework 'Juci' along with the Windows & Blackberry SDKs.
