Numax is a small Rust runtime for distributed applications. It executes WebAssembly (Wasm) modules in a sandbox, incorporates a built-in local key-value store, and ensures data synchronization across nodes using CRDTs and gossip protocols.

Positioned as 'a portable runtime for distributed apps.' The core promise is that 'you write a wasm module, run it on two machines, and they converge,' forming a 'decentralized system.'

Numax addresses the inherent complexity of building robust, decentralized applications by providing a cohesive runtime that integrates WebAssembly, local storage, and CRDT-based synchronization. This approach simplifies the development of distributed systems, offering strong eventual consistency ...

Nucleus – A security-hardened, Nix-native container runtime

A lightweight Linux container runtime, not a Docker replacement, focused on providing stronger, auditable isolation for ephemeral AI-agent sandboxes and declarative NixOS services, with defense-in-depth security defaults, deny-by-default egress, hash-pinned security policies, gVisor integration, Nix-native production path, and formal verification.

Nucleus addresses a critical security and reproducibility gap in containerization, specifically for AI agent sandboxes and NixOS services. By explicitly *not* being a Docker replacement, it carves out a niche focused on deep isolation and auditable security, a paramount concern for untrusted or e...
