A curated list of awesome online implementations of Integrated Development Environments (IDE)

An (IDE) is a software application that provides comprehensive facilities to computer programmers for software development. This typically includes a text editor, syntax highlighting, file explorer, debugger, version control, and build/run/deploy options. Another defining feature of an IDE is some form of intelligent code completion, sometimes called intellisense.

An "Online IDE" has the features mentioned above but runs in a web browser instead of installing as a native application. An "Online IDE" can be made accessible in offline mode without an internet connection and still satisfy the above conditions.
