Codeanywhere

Codeanywhere is promoted chiefly as a code-on-the-go environment—an in-browser, on-tablet, on-phone editor with support for 75 languages and in-cloud execution environments for many of them. But Codeanywhere also has several real-time code sharing and collaboration features. You can just share a project out to others by way of a link, or set up real-time collaboration to allow others to edit your files in your editor. You can also provide other users SSH access to your project.
