Home Assistant is the world's largest free and open-source smart home platform, powering 1 million households globally. It's built on the principle that a smart home should serve its users, not big tech companies, and prioritizes privacy and local control. Powered by a worldwide community of open-source developers, it was ranked the second most active open-source project in the world in 2023 by GitHub.

Nabu Casa was founded to ensure that the development of Home Assistant would remain sustainable as it kept growing. We now employ more than 30 contributors from all over the world to make sure they have the financial freedom to focus on Home Assistant and other open-source projects that help drive the Open Home vision.

Nabu Casa is profitable, has no external investors, and our only funding comes from people subscribing to Home Assistant Cloud and buying Home Assistant hardware. That means the only stakeholders we have to concern ourselves with are our employees and our users.

Our Open Home vision defines the values that we put at the heart of every decision we make. It’s woven into our architecture, licensing, community, and everything else. The Open Home vision is about privacy, choice, and sustainability.

Other Open Home projects supported by Nabu Casa include:

Open hardware tools (e.g., ESPHome, ESP Web Tools)
Open standards (e.g., Python Matter Server, Z-Wave JS, ZigPy, BTHome, Improv Wi-Fi)
Open voice (e.g., Rhasspy, Wyoming Protocol, Piper)

These projects are open source and made available to the whole world to power projects beyond the scope of Home Assistant.
