Spectrum is a real-time web application (and additional functionality in the Launcher and Star Citizen executable) that will handle all community communications in Star Citizen, under development by Turbulent. It was designed to integrate forums, chat, and other key features into one streamlined platform.
Spectrum is first announced in CitizenCon 2016. The initial launch will be a web application, but subsequent releases will include more functionality, such as a fully integrated in-game overlay and voice chat. Looking further into the future, players will even be able to launch the game from Spectrum.
