The Dashboard Behind Home Assistant Is Its Own Open-Source Project

If you've ever poked at a smart home dashboard and wondered how all those tiles, cards, and live toggles actually get rendered, the answer is usually hidden somewhere in a frontend repo. For Home Assistant, one of the most popular open-source home automation platforms around, that frontend is a standalone project you can browse, run, and borrow from. It's the official Home Assistant frontend, and it's sitting right there on GitHub.

What It Does

This repository is the official frontend for Home Assistant. That's the whole pitch, and it's a substantial one. Home Assistant itself is a platform for controlling and automating smart home devices, and this repo holds the interface you actually see and interact with—the dashboard, the cards, the controls, and the UI that ties all those devices together in a browser.

The README keeps things lean on architecture details, but it points you to the important pieces. There's a live demo at demo.home-assistant.io, a screenshot in the docs, and links to the main project and the contributor documentation. If you want to understand how the frontend is built and structured, the development instructions at contributors.home-assistant.io/frontend/development are where the README sends you. The project is open-source and Apache 2 licensed.

Why It's Cool

• It's a real, production frontend you can study. Home Assistant has a large user base, and this is the interface those users actually run. That makes it a genuinely useful reference if you want to see how a complex, component-heavy dashboard is put together and maintained over time.

• There's a live demo. The README links straight to a running demo at demo.home-assistant.io. You don't have to clone anything to get a feel for what the project produces—you can click around first and decide if the code is worth your time.

• There's a dedicated gallery. This is the detail that stands out. The README includes a gallery workflow (cd gallery && script/develop_gallery), which suggests the project ships with a way to develop and view UI components in isolation. For anyone building or contributing to a design system, that's a practical convenience rather than an afterthought.

• Setup is a single script. script/setup handles initial setup, and pnpm build produces a production build. Short, memorable commands are a small thing, but they lower the barrier to getting a local environment running.

• The licensing is permissive. Apache 2 means you can browse, learn from, and reuse parts of the project in your own work. If you're building something adjacent and want to see how a mature team handles frontend concerns, that's a real invitation.

How to Try It

You've got a few paths depending on how much effort you want to put in.

1. Just look at it. Head to the live demo and click around. No setup required.

2. Clone and set up locally. Grab the repo from github.com/home-assistant/frontend, then run the initial setup script:

script/setup

1. Follow the full development guide. The README points to contributors.home-assistant.io/frontend/development for the complete instructions. That's the place to go for environment details and the classic frontend development guide.

2. Build for production. When you're ready:

pnpm build

1. Explore the gallery. For component-level work:

cd gallery && script/develop_gallery

The README also notes that the team uses BrowserStack to test across a wide variety of devices, which tells you something about how seriously they treat cross-device behavior—worth keeping in mind if you plan to contribute.

Final Thoughts

This isn't a library you'll drop into a side project in five minutes, and the README doesn't pretend otherwise. It's the frontend of a large platform, and it's aimed at people who want to understand, contribute to, or learn from that codebase. If you're building a dashboard, working on a design system, or just curious how a widely used open-source UI is organized, the demo and the gallery give you low-friction ways to start. Clone it, poke around, and see what's reusable—the Apache 2 license makes that an easy call.
