Cody++ is a simple and fast web IDE to create C++ applications for ESP32 microcontrollers based on arduino-code syntax.
Checkout the demo.
If you want to take a look at some of the examples mentioned in the menu on the left hand side, feel free to do so.
So far, no installation instructions are needed. Feel free to use the hosted demo. You only have to copy the generated arduino c++ code in a new arduino sketch. Make sure the necessary headers - you find these files in the direcotry /lib - are included.
