osFree project

The open source OS/2 successor

Hi there 👋

Build status Build status

osFree is a Free Open Source software operating system development project, aiming to replace eventually all OS/2 subsystems with Open source analogues. It aims for OS/2 Warp 4 (Merlin) as a base compatibility system, which does not mean that we will not support features of newer (OS/2 Warp Server for e-business, eComStation and ArcaOS) OS/2 versions. This includes rewriting not only user-level code but the OS/2 kernel too.

Getting started

It is, first of all, development project. So, you need to download and configure build environment first. Read http://osfree.org/doku/en:develop:guidelines for more information.
