🚀 WebPi the bridge between modern Linux and your hardware projects.
WebPi is a lightweight C++ web interface framework for the Raspberry Pi. It was designed to make sensors, actuators, and device states controllable via a simple HTTP API and a clean, modern web UI—without the overhead of heavy external frameworks.
"Open, honest, and transparent."
WebPi is not just a tool; it is an invitation to discover the world of C++ and hardware-oriented programming.
WebPi was born from the experience that developing on the Raspberry Pi is becoming increasingly complex and difficult. Between kernel updates (Debian 13 Trixie) and hardware changes (Pi 5), the simple "GPIO feeling" is often lost.
WebPi brings that feeling back. It wraps complex mechanisms into clear, readable interfaces. It doesn't hide how things work—it explains them and makes C++ accessible to everyone.
-
🌐 Self-Contained Ecosystem:
- Integrated HTTP server and modular core system. No external web server like Apache or Nginx required.
-
🔢 Bitmask Logic:
- Efficient, predictable, and easy to visualize. Handling of 8-bit or 16-bit states remains consistent throughout the system.
-
🛠 Modular Power:
- Use only what you need. The user-friendly WebPiEasy offers many simplified wrapper functions.
- From hardware modules (expanders, radio modules, distance sensors) to easy-to-understand board drivers like SPI, I2C, and UART.
-
🔌 GPIO Control:
- WebPi comes with its own simplified GPIO library.
- Configure Output/Input, Read/Write (setPin/getPin), and even a small interrupt function is included.
-
📖 Your Progress:
- Many WebPi functions serve you with default parameters but can be customized with your own values.
-
🛟 WebPi-Start:
- A bash-based control center that manages dependencies and builds at the touch of a button.
- For an easy start, it builds the control and learning platform WebPiUI, allowing you to dive right in.
- Build examples and compare the code with the visual web interface—understand what works, how, and why.

⚠️ WebPi-Apps:- Ready-to-use applications from system and custom libraries. Adapt the applications to your needs and make them your own project.
WebPi is modular and clearly structured. The extensions are not linked to each other and can therefore also be used for your own purposes.

🔢 Hands-on Bitmask Concept WebPi makes binary logic visible. The actuators example shows directly how the internal 8-bit mask corresponds with the web interface.
*Clarity through visualization: Bitmask states in real-time.*
📈 Ready for Real Data Whether it's temperature trends or system logs – WebPi already provides the tools in its core to not only process data but also present it attractively.
*Example of a sensor integration with SVG charts and logbook function.*
🛠️ WebPi Status WebPi is in an advanced stage shortly before its official release. You can follow the development via the source list.
