Good question, the ESP32's use `FreeRTOS` which is a _real time_ operating system (RTOS). Nim's standard library has a `freertos` option now, so you can do `--os:freertos`. It also configures the stdlib's network code to use LwIP which is an embedded TCP/IP stack. What this means is that you can use Nim's nice set of networking libraries, like asyncnet, selectors, etc. It gives a nice modern high level API for networking on any device supporting FreeRTOS & LwIP. FreeRTOS accounts for somewhere around 30-60% of the RTOS market share. Amazon purchased it a few years ago and re-licensed it under a more liberal MIT license (before it was either GPL/Commercial) and use it as the basis of their AWS IoT platforms.
