It maps Juju CLI commands to type-annotated Python methods, eliminating the need for async/await patterns and avoiding websocket failures that plague lower-level alternatives. The library is built for developers writing pytest-based charm tests who want a straightforward, Pythonic interface to deploy charms, wait for readiness, and verify behavior.\n\nThe package depends only on PyYAML and requires the Juju CLI to be installed separately on the system. It supports current Python versions (3.10+) and is actively maintained by Canonical. The project committed to API stability after version 1.0.0, making it a stable choice for long-lived test suites.","worth_installing":"Yes. Jubilant is actively maintained, has low install friction, carries no security vulnerabilities, and offers a stable API (committed post-1.0.0). It directly solves the pain point of charm integration testing with a cleaner alternative to both pytest-operator and python-libjuju. Install it if you write Juju charm tests or automate Juju deployments in Python."},"id":"jubilant","links":{"html":"https://skillfed.io/packages/jubilant","md":"https://skillfed.io/packages/jubilant.md","pypi":"https://pypi.org/project/jubilant/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-30","license_spdx":null,"license_treatment":"permissive","name":"jubilant","python_support":"supports_current","summary":"Juju CLI wrapper, primarily for charm integration testing"},"popularity":{"monthly_downloads":177021,"position":10226,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.12.0"}
