PS4:OpenOrbis SDK

OpenOrbis PS4 Toolchain is in BETA. Some functionality may not be implemented. Please make sure you are using the latest version of the SDK!

OpenOrbis PS4 Toolchain (also known as OpenOrbis SDK) is a legal, open-source and homebrew-oriented SDK (Software Development Kit) which enables developers to build homebrew without the need of Sony's official Software Development Kit (SDK). It contains the header files, library stubs, and tools to build applications and libraries for the PS4.

Why is this needed?

Development and testing on the PS4 is, normally, only for DevNet-registered Development Kits (DevKits) and Testing Kits (TestKits), both being a propriety of Sony Interactive Entertainment, and acquiring and owning these kind of kits is illegal if the user is not a registered developer. Controlling these kits comes with Sony's internal Software Development Kit (SDK) which is also illegal to use if not a registered developer. As a result, both the hardware and software, is in a grey area for homebrew developers and has risks (such as legal action), thus discouraging them to make such homebrew for PS4.

OpenOrbis PS4 Toolchain does not use any Sony copyrighted tools. Being a jailbreak-only SDK, it is based on open source and free tools and does not require the use of any development hardware.

If you are a homebrew developer it is highly recommended to switch your tools to OpenOrbis immediately!
