# hyperlight-sandbox-python-guest — Packaged Hyperlight Wasm Python guest exposed as python_guest.path

License: permissive · Maintenance: active · Downloads: 196.8K/mo

## What it is and what it does

This package is a pre-built Python guest runtime for Hyperlight, a Wasm-based sandboxing system. It allows you to execute Python code in an isolated, sandboxed environment by providing a Python interpreter compiled to WebAssembly. You install it and then reference it using `module="python_guest.path"` or `module_path="python_guest.path"` in the public API.

The package has no runtime dependencies and supports Python 3.10 through 3.14. It is designed as a companion to the Hyperlight sandbox framework, providing the guest-side Python execution layer that runs inside the Wasm sandbox.

Use it for:

- Running untrusted Python scripts in a sandboxed environment for security isolation
- Executing Python code in a resource-constrained or multi-tenant context
- Building serverless or function-as-a-service platforms that execute Python workloads safely
- Testing or validating Python code without exposing the host system to potential harm

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides a Python guest runtime for the Hyperlight Wasm sandbox backend, enabling Python code execution within isolated Wasm environments.

Yes, if you are already using Hyperlight and need Python support in your sandboxed workloads. The package is lightweight, actively maintained, has no external dependencies, and carries a permissive license. However, it is only useful as part of a Hyperlight deployment—verify that it integrates with your version of the main Hyperlight package before installing.

## Install

pip install hyperlight-sandbox-python-guest
uv add hyperlight-sandbox-python-guest
poetry add hyperlight-sandbox-python-guest

## Installing hyperlight-sandbox-python-guest

Before you install: Low install friction with no runtime dependencies. Active maintenance status and recent release (51 days old) suggest ongoing support.

License in practice: Apache-2.0 permissive license allows commercial and private use with minimal restrictions.

Quickstart:

pip install hyperlight-sandbox-python-guest==0.5.0

# Then reference in Hyperlight API:
# module="python_guest.path" or module_path="python_guest.path"

Requires Python >=3.10; intended for use with the Hyperlight sandbox framework

Verify before relying:

- Whether this package requires the main hyperlight-sandbox package to be installed separately or if it functions standalone
- Performance characteristics and memory overhead of the Wasm-based Python guest runtime
- Compatibility with specific Python libraries or C extensions within the sandboxed environment
