Codey Online is a mature, browser-based AI IDE for Arduino and ESP32. Describe your project and get working code plus a wiring diagram drawn with the real components - then flash your board straight from the browser.
If you are exploring AI tools for building hardware, Codey Online is a strong alternative worth trying. It has been helping makers, students and teachers build Arduino and ESP32 projects for three years: you chat with an AI that understands electronics, it writes and repairs the code, and it wires everything up for you - all in the browser, with nothing to install.
Codey speaks your language too: the interface is available in 7 languages, and there are free, Pro and classroom plans, so it fits hobbyists and whole schools alike.
This is where Codey Online stands out. Instead of abstract labelled boxes, Codey draws your circuit with the actual photo of each component - the real board, sensor and display - and places every wire on the true position of each physical pin. Parts are scaled to their real-world size and wires are routed cleanly around them.
The result is a diagram you can follow like a photo of your own desk, which means fewer wiring mistakes and more projects that work first time. Add automatic voltage and logic-level checks (3.3V vs 5V), and you can build with real confidence.
A mature, browser-based AI IDE built around real hardware.
Diagrams use the actual component photos with true per-pin positions - not generic boxes - so building is straightforward.
Snapshot your whole project at any point and roll back to a working version whenever an experiment goes sideways.
Compile in the cloud and flash Arduino and ESP32 over USB with no install, in your own language.
Describe what you want to build. Codey Online writes the code, draws the wiring diagram, compiles it and flashes your board straight from the browser.
