Introduction While C and C++ are not traditional web development languages, they play a vital role in web-connected embedded systems. Especially in IoT projects, these languages power the backend logic, device communication, and hardware-level control that support modern web interfaces. Where C and C++ Fit in Web-Based Embedded Systems IoT Devices & GatewaysDevices written in C or C++ collect sensor data and send it to web servers or cloud platforms via MQTT, HTTP, or REST APIs. WebAssembly (WASM)With tools like Emscripten, C++ code can be compiled to WebAssembly, allowing hardware-level logic to run directly in the browser — ideal for simulations, visualizations, or embedded web UIs. Custom Embedded Web ServersLightweight web servers (like Mongoose) written in C can serve HTML/CSS/JS from devices like routers, smart sensors, or industrial machines. Real-World Applications Industrial dashboards pulling live data from embedded C++ software Smart home devices that serve config pages via local web servers Medical instruments exposing a web-based interface built on a C backend Final Thoughts C and C++ may not build the front-end, but they are essential to embedded systems that communicate with the web, serve content, or process data behind the scenes. Whether it’s a low-level sensor or a full gateway device, C/C++ keep the embedded web world running — fast and efficient.
