Codeanywhere like online development environment

Question

I'm interested in online development, Codeanywhere is pretty fine. However I need something free and where my projects remain "always on" (I mean terminal or PHP)

EDIT: It would be great if there's such an app I can host myself (web script). I tried Codiad, it's just an IDE (that's interesting either) and it doesn't support compiling.

EDIT2: Here's my minimal needs

• Online development environment with Linux terminal support

• Free / trial / open source

• Must continue running after I close my browser

Other:

• Any free or open source web script capable of doing similar things I stated

Answer 1

Here's some I know of:

• Cloud9 - https://aws.amazon.com/cloud9/
• Koding - https://www.koding.com/
  • Was a full Ubuntu machine where you can run (almost) anything. Also had an online IDE.
  • Used the Free tier a while back to do work. Pricing and features have changed since then.
