[NO LONGER MAINTAINED]
Discord+ is a Chrome app that unofficially hosts Discord, a free, secure chat app that supports both voice and text input.
In addition to fully functioning links, videos, mics, and cameras, it also mimics a mobile Discord when the window is shrunken down.
You can register a Discord account with your email address upon opening the app.
When resized below a width of 800 pixels, the app automatically collapses the sidebar to save space. To open the sidebar, click near the left margins of the app. To close the sidebar, click near the right margins of the app.
