Idea type: Freemium

People love using similar products but resist paying. You’ll need to either find who will pay or create additional value that’s worth paying for.

Should You Build It?

Build but think about differentiation and monetization.


Your are here

Creating a real-time operating system (RTOS) to compete with established players like Linux and Windows is an ambitious endeavor. Our analysis reveals that you're entering a 'Freemium' category, meaning users appreciate such projects but might hesitate to pay for them directly. With 8 similar products identified, competition is considerable, indicating a need for strong differentiation. The average engagement (10 comments) across these similar products suggests moderate interest. While we lack explicit 'use' and 'buy' signals, the Freemium categorization highlights the challenge of converting users to paying customers. You'll need to carefully consider how to offer unique value that justifies a premium offering in a space where established free alternatives exist.

Recommendations

  1. Given that similar projects often face skepticism about viability, as seen in the microkernel OS example, focus on demonstrating tangible benefits and a clear roadmap. Communicate your vision and progress transparently to build confidence and credibility.
  2. Since users value the microkernel architecture (like in the microkernel-based OS example), consider highlighting architectural advantages, such as improved security or real-time performance. Clearly articulate the technical differentiators that set your RTOS apart from Linux and Windows.
  3. To address the 'Freemium' nature of the category, identify specific user segments who would benefit most from a paid version of your RTOS. Consider embedded systems developers, industrial automation engineers, or other niches where real-time capabilities and reliability are paramount and where you can charge a premium.
  4. Based on the recommendation for the freemium category, create premium features tailored to these power users, such as advanced debugging tools, guaranteed support SLAs, or specialized libraries. These features should demonstrably save time or improve performance for your target users.
  5. Explore team-based pricing models rather than individual licenses. This can be particularly effective if your RTOS is used in collaborative development environments, as it allows you to capture more value from organizations.
  6. Drawing inspiration from the exaequOS project, which garnered significant discussion, ensure your documentation is comprehensive and addresses potential user questions about architecture, server requirements, and UI/UX standardization. Provide clear examples and tutorials to facilitate adoption.
  7. Consider offering personalized help or consulting services to enterprise clients needing assistance with integrating your RTOS into their systems. This can create an additional revenue stream and foster deeper relationships with key customers.
  8. Prioritize creating implementation examples in your documentation, as highlighted by the criticism of the FOSD project. Provide a basic sample project that shows how to use core features of the operating system.
  9. Test different pricing tiers and feature sets with small groups of potential customers to validate your assumptions and optimize your monetization strategy before a wider launch. Gather feedback and adapt your pricing based on real-world usage.

Questions

  1. Given the competitive landscape, what specific real-time performance benchmarks will your RTOS exceed compared to existing solutions like real-time Linux, and how will you market those advantages to developers in critical industries?
  2. Considering the criticism that some similar projects lack meaningful contribution, how will you ensure your RTOS addresses a significant unmet need or offers a substantial improvement over existing alternatives in terms of security, efficiency, or ease of use?
  3. What is your go-to-market strategy for initially penetrating a market dominated by established operating systems, and what key partnerships or community-building efforts will you undertake to drive adoption among developers and hardware manufacturers?

My microkernel-based OS built from scratch now has basic Unix commands

This project contains no code from Linux, BSD, Minix, or any other OS. Everything up until this point is written entirely from scratch, including a pure microkernel (that only implements multiprocessor priority scheduling, memory management, and interprocess communication), a work-in-progress implementation of the standard C library, and a variety of servers that provide drivers and other essential OS functionality.At the time of writing this post, the servers provide drivers for the keyboard, NVMe SSDs (that works on real hardware), a Unix-like virtual file system (with a single root mountpoint, /dev, /proc, etc.) and several other necessities. The main goal of this project is to research OS design and try to overcome some of the performance penalties associated with microkernels, while also building a general-purpose usable Unix-like OS on top of it. It's also intended to make the study of OS development and theory a little more approachable through self-documenting, clean, and readable modular code.

Users generally appreciate the microkernel architecture, comparing it favorably to Linux and expressing excitement to explore the product. There's mention of an innovative approach with containers. However, there is also a skeptical comment suggesting that the project may not be viable.

Users criticized the product for not meeting the standards set by Linux and for appearing to be outdated or no longer actively developed.

rust-based kernel with asynchronous context switching

31 Mar 2023 GitHub Developer Tools

`rust-kernel-riscv` is an open-source project that implements an operating system kernel on RISC-V architecture with Rust programming language. The kernel leverages Rust's asynchronous programming model to schedule threads in both the kernel and user space, which makes context switching more efficient and eliminates the need of allocating a separate kernel stack for each user process.

SpecOS – A 64 bit OS kernel from scratch

09 Aug 2024 Developer Tools

I've been working on this for ~3 months now, with pretty slow progress to be honest. So far I've got an ATA PIO mode hard disk driver, a FAT32 file system, a real time clock driver, and of course the essentials (interrupts, keyboard, pixel graphics). Kernel panics also cause a blue screen of death xD. It uses a bitmap physical memory allocator, and I'm fixing some issues with paging at the moment as a work towards running userspace applications. I'd be interested to see your thoughts on it :D

Users praised the project and shared positive feedback, with some sharing similar projects. There was admiration for the effort and direction of the milestones. One user joked about their own GitHub, and another expressed nostalgia for a 64-bit DOS that never existed. Additionally, there was a comment expressing love for DOOM.

The product has been criticized for not making a meaningful contribution to society and lacking support for 64-bit DOS.

exaequOS - a new OS running in a web browser

16 Sep 2023 Developer Tools

It is an OS that is able to run Unix/Linux applications locally, in a terminal at the moment, with a graphical environment in the near future. Its microkernel is compiled from C to WebAssembly thanks to emscripten

Users are impressed with exaequOS's ability to run Unix/Linux apps and its web assembly features, but have questions about its development, server requirements, and UI/UX standardization. Some discuss existing tools, UI components, and the need for collaborative standards. Others praise the concept, reference related talks, and express interest in similar projects like daedalOS. There's curiosity about functionalities, storage persistence, and the Same Origin policy. The name exaequOS confuses some, while others debate the choice of Bash as the default shell, suggesting alternatives like Nushell or PowerShell.

Users criticized the product for technical issues like HTTP query bugs, unclear OS state serialization, and ineffective lower-level tools. There's a call for new web standards, with concerns about UI responsiveness and Web Assembly integration. The server requirement undermines browser functionality, and there are issues with file operations and user management. The product's name and concept are seen as confusing and unappealing, with doubts about its practicality. Bash as the default shell is questioned, and there's a need for better thin client integration.

FOSD – Framework of Operating System Development

23 Aug 2024 GitHub Developer Tools

The FOSD(Framework for Operating System Development) Framework is an innovative and flexible framework for operating system development. It strives to provide flexible resources and tools to help developers design, develop, and deploy operating systems efficiently and effectively. The framework is intended to support various architectures and provide corresponding build systems that facilitate the overall development of the operating system. It gives the already-implemented build system for each architecture that can automatically detect and compile user's source code and create a full operating system with proper bootloader(that's suitable with architecture.) The framework also provides HAL(Hardware Abstraction Layer) that can remedy the difficulty of having to develop all the device drivers for every hardware. Although currently, we're in the early development stage of only having x86 architecture kernel that can barely print "Hello, world", we are planning to implement from the fundamental framework features like interrupt system or basic print system to the file system interface, complicated device drivers(corresponding to the architecture) or even feature for task management.The ultimate goal is to make the operating system development easy and efficient for everybody!

Users mentioned earlier projects with similar motivation and expressed interest in OS implementation examples. While they found the idea cool, they noted that the documentation lacks details and had questions about support. One user provided a link to the OSDev wiki main page, and another wished the best for the project.

The main criticisms are that the documentation lacks sufficient details and the examples directory does not include OS implementation.
