HOKA HTTP Web Server Framework For Embedded and IoT Devices

HOKA is an HTTP web server framework for embedded and IoT devices designed to enable the hosting of web services on resource-constrained devices. This framework is typically lightweight and efficient, making it ideal for use on devices with limited processing power, memory, and storage.

At its core, HOKA provides a simple HTTP web server that can handle incoming requests and respond with appropriate content. It includes a set of APIs and libraries that can be used to build custom web services on top of the server. The framework also provides tools for managing network connectivity, security, HTTP cookies, user session, and authentication.

One of the key advantages of HOKA is its ability to enable remote management and monitoring of connected devices. This can be especially valuable in industrial or manufacturing settings, where it may be difficult or impractical to physically access every device.

The framework also offers support for common web protocols and formats, such as RESTful APIs, JSON, and XML, making it easier to integrate with other web-based systems and services.

Overall, HOKA provides a flexible and scalable solution for hosting web services on resource-constrained devices, enabling greater connectivity and remote management capabilities.

Typical HOKA HTTP Web Server Use Case

In this diagram, an embedded device with multiple sensors and actuators runs a web server using HOKA HTTP web server framework.

• The web server is responsible for processing HTTP requests and generating HTTP responses.
• The embedded device can host web pages or web apps, and implement REST endpoints.

When a client (such as a web browser or a mobile application) sends an HTTP request to the embedded device, the request is handled by the web server running on the device. The web server communicates with the device’s sensors and actuators to perform the requested action.

It allows for remote management and control of the device.
Examples of use cases for this architecture include home automation systems, remote monitoring and control systems, and industrial automation systems.

Some additional benefits of using HOKA HTTP Web Server

Reduced energy consumption

Minimizing energy requirements is crucial for web servers running on embedded and IoT devices that often operate on batteries or other limited power sources. HOKA, a lightweight HTTP web server framework, reduces power consumption, enabling devices to operate for extended periods.

Improved reliability

HOKA HTTP web server is designed with robust and resilient features such as error handling and automatic recovery from failures. These features ensure the web server operates reliably, even in challenging environments or under heavy loads.

Simplified development

Developers can simplify development and reduce the time required to launch a web-based application by using a pre-built HTTP web server framework like HOKA. This frees up developers to focus on building their application logic instead of concerning themselves with the underlying web server infrastructure.

Increased security

When coupled with our Security Foundation Library, HOKA HTTP web server comes equipped with in-built security measures such as secure authentication protocols, SSL/TLS encryption, and access controls. This combination can safeguard the device and the transmitted data from any unauthorized tampering or access.


Customizability is a key feature of HOKA, enabling developers to configure the HTTP web server to their specific requirements. This is particularly useful for IoT applications, where the needs of each device or sensor may differ significantly.
