Latest beta release: v353 - May 24, 2023


Did you play RuneScape in 2009? For some OSRS players, a lot of their memories were the times of the newer Abyssal whip, Alchemy spells, and more aesthetic environments and areas. The HDOS client provides OSRS players with a true 2009-era HD experience to play RuneScape in ways they haven’t imagined in over a decade.

Frequently asked questions

What is HDOS?

HDOS, or High-Detail Old School, is a free-to-use third party client for Old School RuneScape that emulates the aesthetic of 2009 RuneScape HD.


For many RuneScape players, the 2007-era graphics do not resonate with them as it was before the time they were truly immersed by RuneScape. The HDOS client allows players that enjoyed the look and feel of 2009-2011 RuneScape to experience that era while playing Old School RuneScape today. Additionally, the HDOS client engine has been rewritten for maximum performance optimization including support for multi-threaded cores. With these improvements, the client is able to run smoothly on lower-end PC builds.

Is HDOS a separate client I have to download?

Yes, just like RuneLite and OSBuddy are third-party clients, so is the HDOS client. The HDOS client can be downloaded through the links at the top of the homepage, with options for the installers or java version.

Is there a risk of being banned if I use the HDOS client?

The HDOS client has NO risk of resulting in a ban. As of June 2022, the client has been reviewed and approved by Jagex:

Is HDOS open source?

The development of this project involves tools that we have designed with the sole intent of client performance and visual enhancements. Some information and parts of code could potentially be used by people that have intents outside of just developing an HD client. Because of this, we believe it is in the best interest of both Jagex as well as the integrity of the game to keep this project closed source until Jagex approves otherwise.

Does HDOS have plugins similar to RuneLite?

Yes, and HDOS plugins are implemented naturally into the client. All plugin settings can be found in the in-game settings menu. The development of plugins and their priority are based on community demand through polls and other feedback. To participate, join the HDOS Discord server to vote in our community polls.

I’m having problems with the HDOS client. What do I do?

The HDOS Discord server has active members that are able to help with common issues.
