The Best Raspberry Pi
Simulator. Ever.
Wire real circuits. Run Python. Watch LEDs blink.
Zero hardware. Zero install.
Built by one person.
For everyone.
Michael Loucks
Founder & Sole Creator
“I built PiForge because the barrier to learning Raspberry Pi shouldn't be owning a Raspberry Pi.
Electronics is one of the most empowering skills you can learn — but for most students, it starts with a $60 hardware kit, a bag of components that get lost, and a setup guide that assumes you already know what you're doing. I wanted to remove every one of those barriers.
PiForge lets anyone open a browser, drop components onto a virtual breadboard, write real Python, and watch a simulated GPIO pin go HIGH — no soldering iron, no hardware, no shipping wait. Whether you're a student in a classroom, a maker experimenting at midnight, or a teacher building a curriculum, this is your lab.
Every line of code, every feature, every design decision — written by me, from my desk. This is PiForge.
Free Raspberry Pi Emulator & GPIO Simulator — Run Real Python in Your Browser
PiForge is the most realistic Raspberry Pi emulator online. Simulate Pi 4, Pi 5, Pi Zero 2 W, Arduino Uno, and Pi Pico W entirely in your browser. Drag and drop 19+ components, use auto-wire suggestions to connect circuits in one click, and run real Python code via Pyodide. The Pi OS-style desktop includes a virtual Terminal, Thonny IDE, and a pre-loaded filesystem with project scripts. No hardware, no install — completely free.
The fully functioning Pi emulator — live in your browser
Pi 4 · Pi 5 · Pi Zero 2 W · Arduino Uno · Pi Pico W — auto-wire circuits, run real Python, watch GPIO respond in real time. 19+ components, Pi OS desktop, virtual filesystem. No hardware needed.
Everything you need to prototype
From realistic hardware to in-browser Python execution — PiForge gives you a complete electronics lab.
5 Boards Supported
Pi 4, Pi 5, Pi Zero 2 W, Arduino Uno R3, and Pi Pico W — each with accurate pinouts, SoC chips, and ports. Switch instantly.
Auto-Wire Suggestions
Click any component and ghost wires appear — showing recommended GPIO, GND, and power connections. Click one to place it instantly. A green snap-ring shows exactly where each wire lands.
Python · MicroPython · C++
GPIO Zero and RPi.GPIO via Pyodide for Pi boards. MicroPython for Pico. Arduino C++ sketch format. All in browser.
Real-Time I/O
Set a pin HIGH and the LED glows. Click a button and your code reads the edge. Bidirectional, sub-50ms.
19+ Component Library
LEDs, buttons, buzzers, DHT22, PIR, servos, HC-SR04, relays, motors, potentiometers, NeoPixels, RGB LEDs, joysticks, OLED, LCD, stepper motors, and more. Live labels show GPIO pin and connection status on every component.
Interactive Wiring Labs
Like a real kit — components are placed for you, but you drag every wire yourself. Live ✅/❌ feedback on each connection. Unlock code only when fully wired.
Live Scene Environments
Your GPIO pins control a living world. Greenhouse plants grow, home lights glow, robot wheels spin — all reacting to your code in real time.
18+ Guided Projects
From Blink an LED to obstacle-avoiding robots. Step-by-step tutorials with auto-wired circuits and complete Python code — ready to run in one click.
Export Anywhere
Export as PNG, hardware build guide, or share link. Take your virtual prototype to real hardware.
Build a circuit in 60 seconds
Choose your board
Pick from Pi 4, Pi 5, Pi Zero 2 W, Arduino Uno, or Pi Pico W. Drop a breadboard and add components from the palette.
Wire it up
Click a component for instant auto-wire suggestions — ghost wires show where every pin should go. Click one to create the real wire, or Shift-click any pin to draw custom wires. Green snap-ring guides you to the exact landing point.
Write & run code
Pick Python, MicroPython, or C++. Choose a template or write your own. Hit Play and watch your circuit come alive.
Guided tutorials for every level
Step-by-step projects that teach you electronics and Python — from your first LED to full sensor dashboards.
Blink an LED
Your first circuit — wire an LED to GPIO 17 and make it blink with Python.
Button + LED
Read button input and control an LED. Learn digital I/O basics.
Traffic Light
Three LEDs with timed sequences. State machines made visual.
Sensor Dashboard
Read temperature and humidity from a DHT22. Display data in the console.
Build real-world projects
From roaming robots to smart home controllers — prototype complete IoT systems before buying a single component.
