XenevaOS is an operating system built from scratch targeted at modern hardware. The OS is designed for both x86 and ARM architectures with plans for RISC-V implementation in the near future as well. Our OS is built on our very own hybrid kernel known as 'Aurora'.
Please visit Build Instructions to build the project
Refer to the Comprehensive Documentation Portal (Table of Contents) for architecture, build instructions, and guidelines.
Refer to Introduction to XenevaOS for a high-level overview.
Refer to API Documentation of XenevaOS. Thanks to ByteJoseph for API docs.
XenevaOS is an open-source project that welcomes contributions from developers, researchers, and enthusiasts who are passionate about low-level system development. Whether you're interested in Kernel development, driver development, low-level graphics, or application-level features, there are many ways to get involved. We encourage contributions in the form of code, documentation, bug reports, and feature suggestions. If you're interested in contributing, check out the Contribution Guideline, explore open issues, and join the discussion to help shape the project.

While writing an Operating System from scratch is a very fun and knowledgeable journey, at the same time it is a deeply challenging one. The project was not started with a specific goal or purpose in mind; rather, it began as a passionate solo developer project that aims to learn and address what existing Operating Systems lack. As the project grew over time, it became necessary to have a clear purpose and goal. Even though it once was a solo development project, XenevaOS has now evolved from a one-person effort to a collaborative team with a shared interest. The strategies and execution of the project are planned and carried out carefully with a deliberate intention.
While there are many mature Kernels available for different domains and they are already feature-complete, they also come with layers of legacy code that make it difficult for developers to implement or experiment with new ideas on top of them. XenevaOS is completely built from scratch and aims to provide a flexible playground for experiments with new designs and architectures with modern computing in mind without compromising on software implementation standards and performance.
- XenevaOS aims to target modern hardware with modern computing architecture in mind.
- To experiment and build an OS from the ground up, transitioning away from traditional OS design as much as possible.
- To ensure that the project has minimal software abstractions as it grows over time for better performance without compromising software implementation standards.
- To make the software as robust as possible, handling software dependencies and errors transparently without affecting the user's flow.
- To research implementing new low-level architectures with security concerns in mind, such as lightweight sandboxes and memory safety techniques.
- XenevaOS aims to be a single core with multiple domains. For example (XR(AR/VR), Robotics, Custom Niche Solutions etc.).
- XenevaOS aims to have native 3D interface as GUI making it suitable for XR(AR/VR) computing.
NOTE: XenevaOS is in early development. Some of the features above are not implemented yet, because the project is in foundation level. But we are committed to exploring each of them through focused iterations and community feedback. Whether you're a developer looking to contribute, or someone exploring alternative OS design, we welcome your curiosity.
