It provides a base class (CharmBase) that charm authors subclass to observe Juju events (config changes, pebble readiness, relation changes) and pair them to handler methods. The library abstracts Juju's event model and state management, letting developers focus on charm logic rather than low-level protocol details.\n\nOps includes a testing module (ops.testing) for unit testing charms in isolation, a Pebble API for managing container workloads, and integrations with PyYAML for configuration, websocket-client for Juju communication, and opentelemetry-api for observability. It is actively maintained by Canonical and is the recommended way to write new charms; the framework is production-stable and widely used in the Juju ecosystem.","worth_installing":"Yes. If you are writing charms for Juju (Kubernetes or machine), ops is the standard, actively maintained framework with low install friction and no security vulnerabilities. It is production-stable and the recommended choice for new charm development. Install it as part of your charm project's dependencies via charmcraft or requirements.txt."},"id":"ops","links":{"html":"https://skillfed.io/packages/ops","md":"https://skillfed.io/packages/ops.md","pypi":"https://pypi.org/project/ops/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-30","license_spdx":"Apache-2.0","license_treatment":"permissive","name":"ops","python_support":"supports_current","summary":"The Python library behind great charms"},"popularity":{"monthly_downloads":484840,"position":6401,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"3.8.1"}
