W3C Web of Things
The mission of the W3C Web of Things (WoT) is to define a universal application layer for the Internet of Things (IoT) built on web technologies, to counter fragmentation and enable seamless integration across IoT platforms and application domains
WoT in a Nutshell
In typical IoT projects, developers face a fragmented landscape of proprietary systems, incompatible communication protocols, differing data models, and varying security requirements. Applications built this way demand high effort for narrow use cases and become difficult to extend, maintain, or reuse over time.
WoT provides standardized building blocks that simplify IoT application development by applying the well-established Web paradigm. This approach boosts flexibility and interoperability, especially for cross-domain scenarios, while enabling reuse of proven standards and tooling. WoT unlocks the commercial potential held back by IoT fragmentation.
Use Cases
The Web of Things technologies apply to a variety of domains and unlock use cases. Whether it be industrial automation, smart home, infrastructure or agentic systems, you can use WoT for your solution. Find out below how the properties, actions, events abstraction over multitude of protocols and domains work.
Read testimonials from industry leaders and W3C members to see how they are adopting the Web of Things standard to drive interoperability and innovation.
