Show HN: Embedr – The AI-Native Arduino IDE

I’ve been working on this over the past few months after getting frustrated with how fragmented hardware workflows can be - switching between code editors, terminals, and toolchains.

Embedr is an AI-native IDE for Arduino and other hardware ecosystems. It helps you code, build, and flash your projects while integrating tightly with the underlying toolchains like the Arduino CLI. The goal is to make hardware development feel as seamless as modern software IDEs.

A key feature is the Embedr Agent, which works like Claude Code inside the IDE. You can describe what you want to build in natural language, and it assists with code generation, debugging, and project setup directly in your workspace.

Current version includes:

- Arduino CLI integration with board detection and flashing - Embedr Agent for AI-assisted development - Built-in terminal and serial monitor - Extensible plugin system for other toolchains (ESP-IDF, STM32, Raspberry Pi, etc.)

You can try it here: https://embedr.app

Still early, and I’d love to get feedback from folks who work with Arduino or embedded systems - what’s missing, what could be better, or what would make this truly useful day-to-day.
