Open source cloud gaming software and other free solutions

Open source cloud gaming software and other free solutions

Cloud gaming allows individuals to play video games that are hosted on remote servers. This eliminates the need to download and install games on a personal computer or mobile device. Games are streamed using a reliable and low latency Internet connection. This method of gaming is similar to the way many of us watch movies over streaming services like Hulu or Netflix.

Open source software is software that allows anyone to inspect and modify the code in any way they see fit. In many cases, cloud gaming can be facilitated with the help of open source software.

What is an open source cloud gaming server?

How does open source cloud gaming server works

Gamers can implement a cloud gaming scenario that allows them to play remotely from any device without purchasing services from a cloud vendor. To accomplish this feat, the gamer must have a competent, physical gaming rig already established on which to play the selected video games. They then need to install dedicated software that makes their games available to other devices by connecting to the remote PC over the Internet.

Cloud gaming open source solutions provide the necessary tools to establish a cloud gaming server that can be accessed as easily as a remote desktop. Issues like cloud gaming latency can ruin a session and make it impossible to play remotely. The dedicated open source software packages address the difficulties of handling user inputs, rendering graphics, and providing real-time displays that can be difficult to optimize for an enjoyable gaming experience. Using an open source solution, a gamer can take their games wherever they like without renting space or resources with a commercial cloud vendor. It’s an economical way to take your games with you wherever you go.

Open source cloud gaming solutions

There are multiple open source cloud gaming packages available for gamers to download and install. In some cases, they may have hardware or performance requirements that may make them inappropriate for your needs. Following are some cloud gaming open source solutions that let you host your favorite video game and play it over the Internet from anywhere you choose.


GamingAnywhere is an open source cloud gaming platform that supports the Windows, Linux, and macOS operating systems for the creation of a game server. The client code can also be ported to the Android operating system, extending the compatibility of this solution to a wider range of mobile devices.

GamingAnywhere’s developers have conducted extensive performance studies that indicate the software provides high responsiveness and video quality while minimizing the demands on network bandwidth. Of course, the open source nature of the solution enables gamers to modify the code to meet their specific requirements.

The motivation behind GamingAnywhere was to attempt to meet the performance demands of cloud gamers. In general, gamers are hard to please and want to enjoy their games without excessive latency. It’s hard to play a game when the response time lags or graphics are displayed incorrectly. An open source project like GamingAnywhere allows gamers and researchers to try new techniques that improve gameplay without additional capital expenditures.

GamingAnywhere provides both server and client components. Users access games by contacting a game portal server and selecting the game they wish to play from the available choices. They are then connected to the game server and can begin playing from any location on a supported device. Client code can be customized to make direct requests from the server without a user interface.

The philosophy behind GamingAnywhere includes the following design objectives.

  • • Extensibility – A modular design makes it easy to replace or modify hardware-specific codecs to extend the capabilities of a gaming system.
  • • Portability – The tool currently supports Windows, Linux, Mac OS X, and Android devices. Modification of platform-dependent components allows users and developers to port the software to other types of mobile devices.
  • • Configurability – Many audio and video codecs are built into the GamingAnywhere software. Configurations can be exported and modified from the generated text-based file.
  • • Openness – The open source project is also meant to serve as a starting point for further research on optimizing cloud gaming performance.


Moonlight, which was formerly called Limelight, is an open source implementation of NVIDIA’s GameStream protocol with a set of third-party clients.
