Voice agent developers
One SDK covers wake word, speech-to-text, LLM routing, text-to-speech and hardware input and output, so you only write what your Ability does.
Local smart speaker builds
It runs on the OpenHome DevKit and any Linux-based hardware, aimed at private, always-on voice AI in the room.
Smart home and IoT control
Abilities can call REST APIs and send MQTT commands to devices such as ESP32, Arduino and Home Assistant.
Device makers
Hardware companies can license OpenHome's on-device intelligence layer instead of relying on closed cloud assistants.
How much does OpenHome cost?
OpenHome does not publish prices: it calls itself an open-source voice AI platform, you build agents on its web dashboard, and its DevKit is given free to developers it picks by application.
OpenHome shows no plans or prices anywhere, and its pricing address leads to an error page. The DevKit is limited and given by application, device makers talk to the team about licensing, and if you add your own model provider keys those providers may charge you. Plans and current prices are on dev.openhome.com.
