CodeSandbox allows developers to simply go to a URL in their browser to start building. This not only makes it easier to get started, it also makes it easier to share. You can just share your created work by sharing the URL, others can then (without downloading) further develop on these sandboxes.
It is a social development environment for front-end designers and developers.. It functions as an online code editor and open-source learning environment, where developers can create code snippets, creatively named "pens", and test them.
