HarixOS – A Linux-Style CLI Operating System for ESP8266

What if an ESP8266 could behave like a real computer?
HarixOS is a CLI-based operating system that runs directly on ESP8266, bringing a shell, filesystem, scripting engine, and safe API layer to microcontrollers.

Instead of scattered firmware logic, HarixOS introduces a structured, command-driven system inspired by Linux. It features a LittleFS-based filesystem (ls, cd, cat), GPIO and WiFi control, system tools, and a .hx scripting engine for automation and mini-apps.

All hardware access goes through a controlled API layer, ensuring safety, stability, and scalability.

Flash it, open a serial terminal, and you get:
