Golioth is an IoT cloud platform for connected hardware, built around a firmware SDK for microcontrollers. It offers device fleet management and the routing of device data to cloud services, so that product teams can connect devices without building their own cloud infrastructure. The service is delivered as a cloud platform, while the SDK runs on the device itself.
The legal entity named on the website is Golioth, Inc., with an address in San Francisco. In March 2026 the company became part of Canonical, the maker of Ubuntu, which is headquartered in London and privately held. Because the contracting entity is American, US law such as the CLOUD Act may apply. The website does not state where cloud data is hosted, so European organisations should check the data processing terms and the storage location before use. The platform is not presented as open source.
