Ways to build
With the Home APIs, any app developer can access over 600M devices, Google's hubs and Matter infrastructure, and an automation engine powered by Google Intelligence - all available on both Android and iOS.

APIs for everyone

  • Build amazing experiences for Matter-enabled and Cloud-to-cloud devices, even those you don’t manufacture

  • Use Google's automation engine to help your customers create a connected, helpful home

  • Connect your digital experiences with physical devices in a customer's home

  • Building for the home is now as easy as building a mobile app

Access 600M+ devices through a single API

Supported devices

Matter devices connected to hubs for Google Home
Cloud-connected Works with Google Home™ devices
Google Nest devices, such as the Nest Learning Thermostat

Great on all platforms. Amazing on Android



  • Fast Pair setup is even more streamlined

  • A modern, Kotlin-based SDK to easily interact with the Home APIs

  • Part of the Google Play Services so your app remains lightweight

  • Easily adopt the Home APIs via Swift libraries

  • Offer the same functionality to your users regardless of mobile platform

Privacy is a priority

Safe & secure

The APIs leverage industry standard best practices for peace of mind
Users can grant and revoke access to their devices at any time
Build with the confidence that your customer data is safe

Commissioning API

Improved Matter setup experience in one API.

  • Simplify device setup with Fast Pair on 3 billion Android devices

  • Commission Matter devices directly in your app, no hub or Matter fabric required

  • Devices can be used in the Google Home app, for voice control via Assistant, or in any app built on the Home APIs

  • Your app will get the same improvements as the Google Home app

Home runtime

Enabling your hardware devices as hubs for Google Home.

  • The Home APIs utilize all existing hubs for Google Home to help optimize Matter experiences for your users.

  • And when you integrate the Home runtime into your own devices, your devices can be used as hubs when using apps built on the Home APIs.

  • Home runtime also enables remote access and low-latency local control of all Matter devices.
