Unlike fragmented solutions, ULTRA OS aims to unify simplicity, performance, and modern design across all devices desktop and mobile—under one cohesive platform.
ULTRA OS will be a next-generation operating system project initially targeting desktop PCs and laptops, with plans to expand to mobile phones and tablets in later stages. Our ultimate goal is to provide a compelling, open-source alternative to today’s dominant platforms.
Currently in the concept and prototyping phase, ULTRA OS is an open-source initiative to create a Resource-efficient but comprehensive operating system to cover both PC and mobile hardware.

ULTRA OS is a practical rethinking of what an operating system should be: fast, focused, and free from bloat. We’re building a platform that prioritizes clarity, performance, and user control — with no corporate influence.
Your donation helps us stay independent, improve developer tools, refine the user experience, and deliver a system built to serve you, not advertisers or shareholders.
Support ULTRA OS — and help shape the future of computing
ULTRA OS is designed to offer a user-friendly yet powerful interface that balances simplicity with depth. It will provide an intuitive experience for everyday users while still delivering the full range of customization and advanced features that power users and enthusiasts expect.
One of ULTRA OS’s core goals is to ensure that all modules are developed with a strong focus on efficiency—minimizing both memory usage and CPU demand. The system is designed to run smoothly on affordable hardware, delivering a satisfying user experience even on lower-spec devices. This makes ULTRA OS a compelling option for schools, budget-conscious users, and communities in developing countries where access to high-end hardware may be limited.
ULTRA OS will be free as based on opensource. ULTRA OS should run even on low-spec affordable hardware. For example: MiniPC <150 USD 14" Laptop < 300 USD AI MiniPC <800 USD Mobile phone < 200 USD
ULTRA OS is built with a strict commitment to user privacy. It does not monitor your activities or collect personal data for advertising or third-party marketing purposes.
ULTRA OS modules are designed with long-term compatibility in mind. Once peripheral devices like printers or scanners are set up and functioning with ULTRA OS, they will continue to work reliably across future OS versions—unless the hardware itself fails. Driver or software updates will not break compatibility.
We envision a specialised version of ULTRA OS that is committed to making computing more secure. A key part of our mission is to reduce vulnerabilities and protect user data. We aim to develop a highly hardened version of ULTRA OS with the goal of achieving an unhackable system architecture. This will be achieved through a closed OS version built entirely on ROM, which does not allow the installation of additional software and blocks the execution of any program not embedded in the ROM itself. While this approach limits flexibility and user freedom, it significantly increases security—highlighting the fundamental trade-off between openness and protection. Low energy consumption ULTRA OS hardware will focus an energy efficient hardware to save electricity.
Linux, with its open-source philosophy, is a great concept that enables programmers to access a vast library of solutions. However, this approach can also have drawbacks: every program often needs to include its own solution for tasks that many other programs also require.
The primary task of most programs is to display data to the user. The user then interacts with the program to alter that data, and the program must display the updated result. This raises the question: why doesn't the operating system itself provide these core display functions, allowing application developers to focus on their actual tasks?
There are standard data types such as text and JPEG images, but many other formats are also common in daily computer use—such as PDFs, spreadsheets, diagrams, statistical charts, music, videos, vector graphics, and 3D models. Another task is event handling for the user interface. Every programmer needs to implement the same task over and over again for each new program. So our idea is why not create a module that handles this tasks automatically and provides all this standard solutions?! Our answer to this is task is UltraCanvas. The OS will provide all major functionality for programmers so they really can focus on the main objective of their programs and not spend 80% of the time to work on secondary tasks to implement the UI. A programming IDE also will provide an easy-to-use tool so that most applications can be built with an minimum effort.
Google’s Android operating system dominates the global mobile market with an estimated 70% share, while Apple’s iOS holds around 27%. This leaves an open opportunity for a strong alternative — ULTRA OS — to emerge as a viable third option.The mobile market generates the largest revenue stream in the entire IT sector. For example:
The Google Play Store produces about $45 billion USD in annual gross sales, yielding Google an estimated $10 billion USD in commission fees (taking a 15–30% share of all transactions).
Apple’s App Store earns even more — approximately $80 billion USD in annual sales — with Apple collecting roughly $21 billion USD in fees.
Beyond app marketplaces, mobile phone companies generate substantial income by selling hardware and offering additional services like cloud storage, AI features, and physical retail support.
In 2025, global mobile phone sales alone reached about $500 billion USD. This means that capturing just 1% of the combined mobile hardware and software market could translate to a potential $5–6 billion USD in annual turnover for ULTRA OS.
There are an estimated 6 billion mobile phones in use worldwide in 2025. Modern smartphones are 20,000 to 100,000 times more powerful than the original ARM-based computers developed by Acorn Computers Ltd. back in 1987. Remarkably, even the 8 MHz ARM chip in the Acorn A3010 was fast enough to run the full RISC OS graphical user interface — proving that today’s phones easily have the computing power needed for desktop-class applications.
In reality, at least half of today’s smartphones are technically capable of functioning as compact desktop PCs. However, they fall short in practice because they lack large displays and because Android was never designed as a true desktop operating system. While there have been attempts to bridge this gap, these efforts often came from the same big tech companies that dominate the mobile market — and true success would have threatened their business models more than it helped.
The truth is: most of us already carry a powerful mini-PC in our pocket every day. So why should people buy a separate desktop computer when their smartphone could handle the same daily tasks?
ULTRA OS aims to change this by unlocking the full potential of modern smartphones — transforming them into fully capable PCs for everyday work and productivity.
The majority of PCs and laptops in use today still rely on Intel’s x86 architecture. To achieve widespread adoption and appeal to general users, ULTRA OS must be fully compatible with x86 processors — ensuring smooth performance on the vast installed base of existing desktops and notebooks. Supporting x86 alongside ARM and RISC-V will make ULTRA OS a truly universal operating system, ready to run on mainstream hardware without compromise.
The RISC-V processor architecture was developed as a fully open-source alternative to proprietary designs like ARM. It delivers comparable performance and cost efficiency while offering developers and manufacturers complete freedom from licensing restrictions and vendor lock-in.
Given ULTRA OS’s emphasis on openness, efficiency, and cross-platform flexibility, it is a natural match for the RISC-V ecosystem. Supporting RISC-V would broaden ULTRA OS’s reach and help strengthen the adoption of open hardware and software standards — empowering innovation without barriers.
The popular Raspberry Pi is an excellent candidate for running ULTRA OS as a lightweight and efficient operating system. Its popularity stems from its affordability and versatility — it can serve as a media center, a development and gaming platform, a web server, a desktop computer, or even as the controller for robots and IoT projects.
The Raspberry Pi is also a valuable educational tool, widely used by educators and students alike to explore computer science, programming, robotics, and electronics in a hands-on way.
Currently, there are an estimated 23 million Raspberry Pi 3 units, 20 million Pi 4 units, and 5 million Pi 5 units in circulation. If each board owner contributed just 0.05 € per Pi, it would generate enough funding to fully support the development of ULTRA OS for this entire ecosystem.
