Awhile back we saw the Russian WIP of PS4HEN called MiraHEN by The Sugarleaf, and today scene developer @Mathieulh shared a few details on their other projects including OpenOrbis ***- a free and legal PS4 development kit, OpenOrbis Toolchain- tools, patches and scripts to build PS4 homebrew and OpenOrbis Marketplace- an online marketplace for homebrew publishing similar to Cydia but without the repos. 
According to Mathieulh, to quote: "The only place to find information on OpenOrbis is the github, any discord, twitter, reddit, or any social media otherwise is fake."
He also confirmed, "It's legit, someone from the group has asked me to tweet this" and that "It's a placeholder for now" although other PS4 developers including BigBoss replied with "They should change the open in the name then. Try to build a dev community without sharing sources is stupid."
Here are some details from Github on the OpenOrbis project, as follows from the README.md:
OpenOrbis - ***
OpenOrbis Team strives to provide an open source, free, legal *** for development of the PlayStation 4 console. We will not be providing any interfaces for kernel development. With this being said all of the things that will be included are as follows
The toolchain will provide you with the tools, patches, and scripts neccessary to start building your own homebrew with the OpenOrbis - ***. The parts included are as follows

OpenOrbis - ***
OpenOrbis Team strives to provide an open source, free, legal *** for development of the PlayStation 4 console. We will not be providing any interfaces for kernel development. With this being said all of the things that will be included are as follows
- Software Development Kit
- Portable Homebrew/Payload Launcher Source (Currently for 1.76/5.01)
- Replacement LLVM lld linker for no-prototype/stub generation of source code
- In order to ease development of userland applications like emulators, media players, and homebrew games, we have included a fully modified LLVM linker to replace the standard. This linker will automatically generate the approperate imports and import id's needed to run using the provided loader (TOOD: Link to source)
- Faster compile times than other competitve homebrew software development kits
- flatz (overall badass)
- specter (4.05 kernel exploit implementation)
- mistawes
- apache
- hydrogen
- rebug
The toolchain will provide you with the tools, patches, and scripts neccessary to start building your own homebrew with the OpenOrbis - ***. The parts included are as follows
- LLVM + Clang (5.0)
- OpenOrbis customized LLVM LLD (Linker)
- These configurations have only been tested on Ubuntu image of Windows Subsystem for Linux, Ubuntu 16.10, and CentOS
- Other platforms, you are on your own; But feel free to send us a PR to add support to more platforms!
