It begins with something small: a brand-new device that won't accept a file, because of a format it isn't allowed to use. Behind that is a larger idea — a secure, high-performance operating system on open hardware, where what a device can do is decided by its hardware, and by you. Begin with the vision. Then see what already runs.
Why Open Nexus exists: an open source operating system on open RISC-V hardware, where what a device can do is decided by its hardware and its owner.
What the Open Nexus RISC-V operating system runs today in QEMU, what lands next in 2026, and how the path to real RISC-V hardware is sequenced.
