Velxio — Introduction
Velxio is a fully local, open-source Arduino emulator that runs entirely in your browser.
Write Arduino C++ code, compile it with a real arduino-cli backend, and simulate it using true AVR8 / RP2040 CPU emulation — with 48+ interactive electronic components, all without installing any software on your machine.
Why Velxio?
- No installation required — everything runs in the browser.
- Real emulation — not a simplified model, but accurate AVR8 / RP2040 CPU emulation.
- Interactive components — LEDs, buttons, potentiometers, displays, sensors, and more.
- Open-source — inspect, modify, and self-host it yourself.
