velxio

Velxio is a browser-based development tool that lets you emulate, code, compile, and run projects for 19 real boards—including Arduino Uno, ESP32, and Raspberry Pi 3—without any physical hardware or cloud dependency. It’s designed for makers, students, and embedded developers who want to prototype, test, and debug firmware instantly from any device. The project is interesting because it removes hardware barriers and limits, enabling rapid iteration and learning directly in the browser.
