SDK for frontier embedded agents, in Rust. One runtime for the Codex and Claude harnesses, with their own prompts and tools, that runs in a terminal, a server, a Worker, a browser tab, or an app.

• Durable. Every model call and tool call is journaled, so a turn finishes after its process dies.
• Code Mode. The model writes one program that calls every tool, and only its result enters the context.
• Hands. No sandbox per session. A turn reaches a laptop, a server, or a browser tab only for the calls that need one.
• Subagents. A cell spawns children, each a durable session of its own.
• Any payer. A ChatGPT or Claude subscription, an API key, or Machine Payments from a Tempo Wallet.

The CLI

curl -fsSL https://nanocode.xyz/install | sh
nc

The SDK

[dependencies]
nanocode = { git = "https://github.com/nanocodexyz/nanocode" }

The same code runs in other languages:

Language	Repository
TypeScript, as one WebAssembly module	nanocode-ts
Swift, for macOS and iOS	nanocode-swift
C, for a game engine or any other host	libnanocode

The crate layout describes the workspace, and DECISIONS.md records what each change established.
