aarch64 and amd64, and follow their upstream projects’ releases without anyone having to remember to check.
Home Assistant renamed add-ons to applications in 2026, and both names still appear in its own tooling. If your Home Assistant says “add-on”, these are the same thing.
Add the repository
One address, added once, and every application appears in the store.
Catalogue
What each application does, and where its web interface is.
How they are packaged
Hostnames, updates, backups, storage and the watchdog.
Browse the catalogue site
home-assistant.kansolabs.org, generated from the applications themselves.
Where each application is documented
Every application has its own documentation in itsDOCS.md, which Home Assistant shows on the application’s Documentation tab once it is installed. It covers the options, the ports, what is mapped and how it is backed up. This site covers what is true of all of them, and links to each one’s page from the catalogue.

The packaging lives in kanso-labs/home-assistant-applications, and its work is planned on the Home Assistant Applications project. ItsAGENTS.md is the reference for adding or changing an application.
