The webIDE made by adafruit is an easily installed IDE hosted on the pi that can be accessed remotely and host bots and run code. When you finish installing it, you can run scripts using Python, .js and many other languages used for web applications.

it has a terminal, access to your filesystem, and can be configured to use a password.

without having to worry about shutting off your computer leading to your bots going offline you could probably leave your bot development projects going easier.

if someone decides to use an exploit on your bot, it wont go directly to your own computer.

you don't have to worry about the set up as much as you would on other systems because it is just that easy to set up.

if you forward your ports, you can access it from your phone allowing you to code from your phone.

and the Pi consumes a lot less power and can be left headless simply plugged into an outlet running this as a server silently.
