The Unbound SDK lets you develop proprietary NPKs, drivers, and applications without forcing source disclosure. Your IP stays yours.
You can build proprietary products on Nexus. The SDK does not infect your code with GPL or any copyleft. Your NPKs, your drivers, your applications — your intellectual property. We sell the Forge, not your freedom.
Packages distributed through the Sovereign Bazaar are expected to carry a signature and build proof. The current public proof pack has registry validation, badge evidence, and one development hello-NPK host proof. Production Ed25519 signing remains future Forge/Bazaar work.
C API for NPL development. ION Ring open/read/write, NRP query, capability request, KDL parse helpers.
API Docs →Package manager for building, signing, and publishing NPKs. Content-addressed, graft-capable, mesh-aware.
Packaging Docs →Package metadata format: type, capabilities, pledges, dependencies, edition constraints.
Manifest Spec →How to bridge to and from POSIX worlds. Run Linux drivers in NipCells. Export NRP queries as REST.

Works as a development proof. The checked-in nip CLI creates,
builds, dev-signs, installs, lists, inspects, and executes this local NPK.
nip init creates a KDL manifest and source skeleton.
nip sign currently writes a development BLAKE3 signature sidecar;
production Ed25519 signing is a Forge/Bazaar follow-up.
Driver capsules declare their interface, capabilities, and pledges in the manifest. The Forge validates that the binary only uses declared capabilities at link time.
The NPL membrane lets you bridge native Nexus protocols to external worlds. REST, gRPC, WebSocket — all via structured ION Rings, not POSIX sockets.
First-class support. Fibers, channels, ARC/ORC memory. The kernel itself is Nim. Your NPL code runs closest to the metal.
Hardware abstraction, drivers, interrupt handlers. Comptime evaluation. No hidden allocations. C-level control without C-level insanity.
Link against libnexus. Use ION Rings, NRP queries, and capability tokens from standard C. No POSIX required.
Our own unification language. When Janus matures, it will subsume the Zig/Nim split. Future-proof your architecture.
Run inside a NipCell or bridge via the NPL membrane. Rust's safety model complements Nexus's capability algebra.
Run as guest workloads inside NipCells, or bridge through gRPC/REST. Bring your existing tools.
The Unbound SDK does not impose copyleft on your work. You can ship closed-source NPKs, proprietary drivers, and commercial applications built on Nexus. Your IP is yours.
