RISC OS Open Ltd. (also referred to as ROOL) is a limited company engaged in computer software and IT consulting. It is managing the process of publishing the source code to RISC OS. Company founders include staff who formerly worked for Pace, the company which acquired RISC OS after Acorn's demise.
The source code publication is facilitated by a shared source initiative (SSI) between ROOL and Castle Technology (CTL). ROOL hopes that by making the RISC OS source code available for free it will help stimulate development of both the RISC OS source code and the platform as a whole.
Operations exist to facilitate tasks related to ROOL's goals. Additionally, staff undertake development work on the code themselves. Since early 2009, ownership, development and sales of the  As a development from the initial goals, in 2011 ROOL introduced a bounty scheme to encourage further development.tools were transferred to RISC OS Open.
Discussions of a technical and more general nature take place on the forum. A thread entitled "Let's get started with a Pandora port" witnessed discussion of porting to the Cortex-A8 used in the Pandora handheld game console. The thread was started in September 2008.
