The package works by downloading pre-built wheels from a centralized hub (maintained separately) and populating charmcraft's pip cache before packing, so subsequent builds reuse those wheels.\n\nIt is a CLI tool installed via pipx that wraps charmcraft's pack command. It requires charmcraft.yaml to use multi-base shorthand notation (where build-on and build-for are identical), and it works within charmcraft's LXC container model. The tool is most useful in CI environments and on fresh machines where the pip cache is empty.","worth_installing":"Yes, if you build charms regularly and want faster first-time builds. The tool is actively maintained, has low install friction, and solves a real pain point in charmcraft workflows. The unclear license is a minor concern to verify before production use. Not relevant for non-charmcraft users."},"id":"charmcraftcache","links":{"html":"https://skillfed.io/packages/charmcraftcache","md":"https://skillfed.io/packages/charmcraftcache.md","pypi":"https://pypi.org/project/charmcraftcache/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-04-06","license_spdx":null,"license_treatment":"unclear","name":"charmcraftcache","python_support":"supports_current","summary":"Fast first-time builds for charmcraft"},"popularity":{"monthly_downloads":135975,"position":11411,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.8.5"}
