JustRun.It is a web application that allows users to write, run and share code snippets in any language* from a web browser A.K.A JSBin for server-side programming languages.

Users are freed from the hassle of setting up a language runtime just for writing a short block of code in it. Developers can now share code along with its runnable execution context with their peers.

• Python
• Ruby
• PHP
• Javascript (NodeJS runtime)
• Golang

• Docker-powered Isolated execution environments for all snippet runs.
• Allow users to author snippets in a editor that supports Syntax Highlighting.
• Terminal Emulator which pipes the running snippet's STDOUT/STDERR streams to the browser.
• Ability to run snippets and see the results, as they arrive, on the terminal.
• Automatic dependency detection and installation for Python, Ruby and NodeJS snippets.
• Allow users to manually list their dependencies for PHP snippets.
• Allow users to fork other users' snippets as a starting point for their own.
• Allow users to see lint their snippets.
• Allow users to change the editor theme and persist the change across sessions.

JustRun.It is composed of three main components:

Potts is a REST Server written in Go that manages JustRun.It snippets and their metadata.

Fury is a REST Server written in Go that executes JustRun.It snippets in Docker containers.

It uses Go channels extensively to pipe the STDOUT/STDERR stream of the running snippet to the user's browser via WebSockets.

Stark is a AngularJS-powered client application.
