@nimbus-sh/runtime-cpython

CPython 3.13.14, cross-compiled to wasm32-wasi, with its stdlib, packaged for Nimbus.

This package is data: the runtime's wasm and support files, content-addressed, plus the manifest that describes them. It does nothing on its own — @nimbus-sh/core installs it into a workspace filesystem and runs it.

npm install @nimbus-sh/core @nimbus-sh/runtime-cpython

import { NimbusWorkspace, localFacetHost } from '@nimbus-sh/core';
import cpython from '@nimbus-sh/runtime-cpython';

const workspace = await NimbusWorkspace.create({
  sql,                       // your SQLite, through the SqlDatabase port
  facets: localFacetHost(),
  runtimes: [cpython],
});

Every file is verified against the manifest's SHA-256 before it reaches the filesystem. The same bytes are served to Cloudflare deployments from R2 by nimbus install cpython, under the same manifest.
