Nabu Casa

Nabu Casa (operating at nabucasa.com) is a cloud infrastructure and integration platform engineered for home automation enthusiasts and developers. Founded in 2018 by the founders of Home Assistant, the open-source home automation platform, and headquartered in Irvine, California, Nabu Casa bridges a critical gap in the ecosystem by providing the missing cloud component for Home Assistant. While the open-source platform excels at local automation, it lacks built-in remote access and seamless voice assistant integration. Nabu Casa solves this by offering Home Assistant Cloud—a subscription-based service that enables secure remote access, voice control via Google Assistant and Amazon Alexa, and integration with nearly any smart home device. Under the hood, the platform leverages secure cloud infrastructure to extend Home Assistant’s capabilities beyond local networks, ensuring privacy and reliability. This allows homeowners and developers to automate their smart homes from anywhere, control devices via voice commands, and expand functionality without sacrificing security. The company operates independently, with no external investors, and funds the broader Home Assistant Foundation’s development, reinforcing its commitment to open-source innovation.
