Show HN: CrossRun – An Open Standard to Make Software Run on Any Platform

4 weeks ago 1

Welcome to CrossRun! This repository is the home of our project’s vision, mission, and core values. CrossRun is more than just a tool—it’s a movement to make software truly universal.

CrossRun exists to make software run anywhere. No matter the operating system, processor architecture, bitness (32-bit, 64-bit, ARM, x86, etc.), or environment, any app should just work. We are building a universal standard that removes barriers between platforms, letting developers focus on creating, not on compatibility headaches.

We imagine a world where apps are not tied to a single platform or architecture. Developers and users shouldn’t have to worry about which OS or processor they have. Your favorite software should run seamlessly on Windows, Linux, macOS, ARM devices, x86 machines, or whatever comes next.

CrossRun is a future where:

  • Apps compiled for one system run effortlessly on another.
  • Users can install software without fear of incompatibility.
  • Developers spend more time innovating and less time troubleshooting environments.
  • Open standards unify the software ecosystem, making it truly universal.
  • Universal Compatibility – No bit left behind. No ISA unsupported. Every app runs everywhere.
  • Open and Free – CrossRun is completely open-source, free for anyone to use, modify, and share.
  • Collaboration – Open standards grow through community. Everyone’s ideas are welcome.
  • Simplicity – Compatibility should be easy, not complicated.
  • Inclusivity – Everyone can contribute, regardless of location or skill level.
  • Innovation-Friendly – Developers should push boundaries, not fight environments.

The software world is fragmented. Users struggle with apps that “only work on this system,” and developers spend hours building multiple versions of the same software. CrossRun aims to:

  • Save developers time by removing the need for multiple builds.
  • Empower users to run any software on any device.
  • Encourage innovation through universal standards.
  • Unite ecosystems by creating a platform-independent standard.

At its core, CrossRun is about standardizing interoperability. This includes:

  • Abstracting differences in instruction set architectures (ISAs) so software can run regardless of processor type.
  • Supporting multiple bitness modes (32-bit, 64-bit, etc.) without requiring separate builds.
  • Enabling apps to run on different operating systems without modification.
  • Providing a set of tools and guidelines for developers to adopt this standard easily.

We want the community to grow with CrossRun. Here’s how you can help:

  1. Contribute Ideas – Open an issue to propose improvements to the standard.
  2. Develop Tools – Build open-source tools that make adoption easier.
  3. Spread the Word – Share the manifesto, educate developers, and inspire adoption.
  4. Participate in Discussions – Join our discussions to help shape the future of universal apps.

Check out CONTRIBUTING.md for detailed guidance on contributing.

CrossRun is more than a technical solution—it’s a philosophy. We believe in a future where software transcends the limits of hardware and OS. Where an app written today can still run decades from now on devices that don’t even exist yet. A world where “it doesn’t work on my machine” is a phrase of the past.

Together, we can make software universal. CrossRun is the first step toward a truly interoperable future.
