Just describe your idea. Codey writes the code, draws the wiring diagram, compiles it in the cloud, and uploads it straight to your board — all from one browser tab. No IDE, no driver hell, no setup.
You can run it directly from a USB drive or any folder on your PC without modifying system registries.
The 7.4 update introduced several stability improvements and technical additions that remain popular among the community: Cheat Engine
While the official "clean" portable version is often restricted to Cheat Engine's Patreon members, many users create their own by manually extracting the files using tools like InnoUnp . Key Features of Version 7.4
Repacks typically remove the promotional offers (like browser toolbars or security software) often found in the free public installer.

Cheat Engine 7.4 is a powerful, open-source memory scanner and debugger designed for gamers and developers who want to modify single-player games. While the standard installer is known for bundling "OfferCore" or third-party adware, a offers a streamlined, "clean" alternative that runs without installation.

Every Codey project comes with a real wiring diagram. Color-coded wires, labeled pins, and a complete connection table — exportable as PDF or printed straight from your browser.
Red for 5V, black for GND, signals in distinct colors — exactly how you'd draw it on paper, only neater.
Below every diagram you get a Wire From → To list with pin labels, so you can wire your circuit without guessing.
One click to download a printable PDF of the diagram — handy for workshops, classrooms or your own build log.
Codey ships with a library of common modules: OLED displays, DHT11/22, HC-SR04, servos, relays, MOSFETs, RGB LEDs and many more.
Codey works out of the box with the most popular development boards. Plug one in over USB, pick it from the dropdown, and start vibing.
The classic. ATmega328P @ 16 MHz, 14 digital I/O, 6 analog inputs. Perfect for beginners.
Compact ATmega328P board. Same brains as the UNO, breadboard-friendly form factor. cheat engine 74 portable repack
54 digital I/O and 16 analog inputs. The go-to when one UNO simply isn't enough.
The popular WROOM-32 module. Dual-core 240 MHz, Wi-Fi + Bluetooth, 30 GPIO. You can run it directly from a USB
Beefy S3: 16 MB Flash, 8 MB PSRAM, native USB-CDC. Two USB ports — Codey knows which is which.
RISC-V single-core, ultra-low-power, USB-C and a built-in OLED. Tiny but very capable. Everything You Need to Know About Cheat Engine 7
More boards added regularly. Direct USB upload over Web Serial — no drivers, no Arduino IDE required.
If you love vibe coding with Cursor or Claude Code, you'll feel right at home in Codey. Same describe-it-and-it-builds flow — except Codey runs your code on a real Arduino or ESP32, not on a server.
You can run it directly from a USB drive or any folder on your PC without modifying system registries.

Cursor and Claude Code are excellent general-purpose AI coding tools — we use them ourselves. They're just not made for blinking an LED on a microcontroller. Codey Online fills that gap. Cursor® is a trademark of Anysphere Inc.; Claude™ and Claude Code™ are trademarks of Anthropic PBC. Not affiliated with either company.
Start vibing for free. Upgrade for unlimited AI and pro power.
For students and hobbyists.
For makers and creators.
Codey Online is built by OTRONIC, a Netherlands-based electronics company. We're passionate about making hardware programming accessible to everyone — from primary-school kids to professional firmware engineers.
We saw too many beginners give up on the traditional Arduino IDE because of driver issues, missing libraries and cryptic C++ errors. Codey closes that gap with modern AI and Web Serial — so you can stay in the flow and just vibe your way to a finished project.
