HACS (Home Assistant Community Store) is an MIT-licensed Python integration that gives Home Assistant users a user interface for discovering, installing, tracking, and updating custom elements without leaving Home Assistant itself.
What it is
HACS is a Home Assistant integration, written in Python, that acts as a package manager for custom elements inside the Home Assistant ecosystem. It is published on GitHub under the MIT licence, carries the topics community, hacs, home-assistant, integration, and package-manager, and points users to hacs.xyz for its general documentation and its basic configuration guide. In the project's own words, it is an integration that gives the user a powerful UI to handle downloads of custom needs.
The concrete problem it solves is the manual handling of custom elements. The project's stated highlights are discovery, download, tracking, and management of custom elements — including downloading, updating, and removing them — together with shortcuts to repositories and issue trackers. What it replaces is the out-of-band routine of sourcing custom elements by hand, placing them into a Home Assistant installation, and keeping track of what was installed and what has changed. HACS moves discovery and lifecycle management into the Home Assistant interface instead.
Key capabilities
- Discovery of new custom elements from within the Home Assistant UI.
- Download and installation of custom elements.
- Tracking of the custom elements a user already has.
- Management operations covering download, update, and remove.
- Shortcuts that link straight to each element's repository and issue tracker.
- Configuration handled through the documented basic configuration flow at hacs.xyz/docs/use/configuration/basic.
Who uses it and how
- Home Assistant administrators who want to add custom elements without manually placing files or tracking versions themselves.
- Community publishers who distribute custom elements and benefit from the shortcuts HACS provides to their repositories and issue trackers.
- Users maintaining an existing set of custom elements over time, using the update and remove operations to keep that set current.
- Contributors and users who need help: the project directs bug reports to its GitHub repository and offers a Discord server for community support.
Getting started
Installation and set-up follow the official documentation at hacs.xyz, with the basic configuration steps described at hacs.xyz/docs/use/configuration/basic. The README itself does not name a package, container image, or compose file, so the documentation site is the authoritative starting point.
How it compares
No comparable or paid products are named in the facts for this entry, and the project lists no commercial alternatives that it replaces. HACS therefore stands alone in this registry as the Home Assistant Community Store integration.
When to use it — and when not to
HACS is only meaningful for people already running Home Assistant, since it is an integration for that platform rather than a standalone tool. Anyone who does not operate a Home Assistant instance, or who prefers every detail documented inside the repository rather than on the external hacs.xyz site, should look elsewhere. The repository's README excerpt is brief and defers most substance to the documentation site, and the project carries 164 open issues, so prospective users should expect to rely on the linked documentation and the community Discord and issue tracker rather than on in-repo guidance alone.
