Starlark is built around hermetic execution (no filesystem, network, or clock access), deterministic evaluation (same code always produces the same result), and parallel-safe immutable data. This makes it suitable for running untrusted code safely, configuration languages, and build system scripting.\n\nThe package provides Python bindings via PyO3, so you can instantiate a Starlark interpreter from Python and evaluate Starlark code within a sandboxed context. It ships with prebuilt wheels for Linux (x86_64, aarch64, armv7l), Windows, and macOS, making installation straightforward. The single runtime dependency is typing-extensions, keeping the footprint minimal.","worth_installing":"Yes, if you need sandboxed, deterministic code execution with a Python-like syntax. The package is actively maintained, has no known vulnerabilities, and offers prebuilt wheels for easy installation. However, verify the license terms first\u2014the package metadata does not declare an explicit license, which could be a blocker for commercial or restricted-license projects. Start with the documentation and a small proof-of-concept to confirm the API and performance meet your use case."},"id":"starlark-pyo3","links":{"html":"https://skillfed.io/packages/starlark-pyo3","md":"https://skillfed.io/packages/starlark-pyo3.md","pypi":"https://pypi.org/project/starlark-pyo3/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-05-18","license_spdx":null,"license_treatment":"unclear","name":"starlark-pyo3","python_support":"supports_current","summary":"Wraps starlark-rust into Python"},"popularity":{"monthly_downloads":356691,"position":7280,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2026.1"}
