A full Arduino IDE in your browser, with an AI assistant that writes and fixes code, an online compiler and one-click flashing - nothing to install.
The classic Arduino IDE is a plain text editor. Codey Online is a modern, browser-based IDE with an AI pair-programmer built in. It writes sketches, explains errors, manages libraries and keeps a per-project file tree - so you spend time building, not configuring toolchains.
Codey compiles server-side with arduino-cli and flashes over USB using Web Serial. Multi-file projects, automatic library installation and a live serial monitor are all included, in Chrome or Edge, on any operating system.
AI, cloud compile and flashing without a single install.
An assistant that writes, explains and repairs Arduino code lives right inside the editor.
Compile with arduino-cli in the cloud; missing libraries install themselves automatically.
Flash over USB and watch serial output live, all in the browser tab.
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.
