The AI code editor for ESP32

Cursor-style AI, built for ESP32

The ESP32 is powerful - Wi-Fi, Bluetooth, dual core - but that power comes with fiddly details: 3.3V logic, board variants and a maze of libraries. Codey Online handles that for you. You describe the goal, the AI writes the ESP32 code, picks the right libraries and warns you when a sensor needs level shifting.

Flash ESP32 straight from the browser

Codey compiles your ESP32 sketch in the cloud and flashes it over USB using the built-in web uploader - no esptool setup, no Arduino IDE. It supports ESP32-WROOM, ESP32-S3 and ESP32-C3, and generates a wiring diagram for every project.

Why it is the Cursor for ESP32

AI code generation, wiring and flashing for every ESP32 variant.

📶

Wi-Fi and IoT code in seconds

Ask for a web server, MQTT client or sensor logger and Codey writes ready-to-run ESP32 firmware.

🤖

Knows 3.3V gotchas

Codey flags logic-level and voltage issues in the wiring so you do not fry a sensor or a pin.

🔌

One-click flashing

Upload to ESP32-WROOM, S3 or C3 over USB from Chrome or Edge - no drivers or command-line tools.

Cursor for ESP32 - FAQ

Which ESP32 boards can Codey flash?
ESP32-WROOM, ESP32-S3 and ESP32-C3 are supported, flashed over USB with the browser uploader. Arduino boards work too.
Can it write Wi-Fi and Bluetooth code?
Yes. Describe what you need - a web dashboard, MQTT, BLE - and the AI generates working ESP32 firmware with the right libraries.
Do I need esptool or the Arduino IDE?
No. Codey compiles in the cloud and flashes from the browser using Web Serial, so there is nothing to install.
Is it free to try?
Yes. Start for free; Pro adds higher limits and extra features for 9.99 euro per month.
