An interesting site if you are doing Arduino/STM32/ESP32/RP2040 based projects; especially if using MicroPython
Seems to work quite well, design, code and simulation. Rather similar to Fritzing; but more up-to-date. Might be worth checking out for simple projects and examples.
FYI, for the Pi Pico (which Wokwi also supports), you can right click the code window and find an option to download the .uf2 file to directly load into the device. In other words, you don’t need to install /anything/ on your PC to use it!
The comments at the end of this project explain the process in detail
