AOSP for Xperia Z3
What is the Android Open Source Project?
The AOSP Project aims to allow developers to build Android for their own devices and to customize it to their own liking. With AOSP, many OEMs and self-lead development teams are able to modify and create their own versions of Android for their devices. As such Android ROMs such as AOKP and CyanogenMod are born.
Before proceeding;
Your device is bound to any type of risks if you are to flash any builds that are stated in this thread. This builds are EXPERIMENTAL and may not work! To flash this builds to your device, you need to have an UNLOCKED BOOT-LOADER on your Xperia Z3.
How is this version of AOSP built?
This version of AOSP is built from SOURCE on a Dedicated Server. Sources and build guides follow those that are posted alongside Sony's Developer World Webpage and GitHub. Find out more here: http://developer.sonymobile.com/knowledge-base/open-source/open-devices/aosp-build-instructions/how-to-build-aosp-kitkat-for-unlocked-xperia-devices/
How frequent do builds arrive?
Builds that come directly from my server follow the standard build schedules you might see on CyanogenMod's Jenkins. It is being operated by Build Bots that are constantly building AOSP Roms for the device specified in this case, the Xperia Z3 (Codenamed: LEO). The builds are not necessarily stable and require human-made modifications to improve the builds. Because of that, builds may arrive slower than CM's builds, typically, every week will have at least one build released. Builds are operated on my build server and published on the my Download Portal.
There is also this reason that is brought about by another developer:

To help with keeping my server running, do feel free to donate at my website!
Server costs are as follows: $8 for build servers, $5 for Bandwith. Other than that, you will be just helping to fund the servers for longer periods of times and allow me to donate to charities. You are strongly advised to donate if you ONLY have the money. If not, keep it for more important things in your life

" User: When is the next build coming?
Developer: Well, considering that I don't get paid and have to spend hours modifying codes and creating ROMs, then well I guess you can might as well build it yourself if you want it in 24 Hours?? "
