Are you passionate about open-source, Rust, or RISC-V? Do you want to help shape a next-generation mobile operating system that’s privacy-respecting, modular, and designed for tomorrow's hardware?

Then open nexus needs you.

What is open nexus?​

open nexus is an open-source mobile operating system built from the ground up in Rust, with a strong focus on privacy, openness, and interoperability. It is based on the Redox microkernel and the beautifully modern COSMIC desktop environment (originally developed by System76).

Our goal? To create a secure, modular OS that runs across mobile and embedded platforms – fully open, community-driven, and libre.

The Problem: Locked Ecosystems Limit Innovation​

Today's devices force us into walled gardens:

• Smartphones ≠ Desktops: Different OSes, disjointed workflows
• Cloud-Dependent: Your "ecosystem" relies on third-party sync
• Hardware Silos: A Desktop App can't adapt to a Tablet
• Proprietary Eco Systems: Forces everyone to develop their own

This isn't just inconvenient - it's a fundamental design flaw.

Our Vision: One OS, Any Device​

Introducing open nexus: A Rust-based microkernel OS designed for adaptive computing.
