Discord is a communications platform for voice, video, and text, with communities organized into servers and channels. People can create servers for groups to talk and spend time together, and use calls in direct messages, group direct messages, or voice channels. The service supports streaming games to friends, and supported consoles can stream gameplay directly. On desktop and in a browser, the App Directory lets users find apps to add to a server or account. Account Connections can link services such as Spotify, Xbox, and PlayStation to a profile; developers can use the Embedded App SDK to build interactive experiences inside Discord. It runs on the web, Windows, macOS, Linux, iOS, and Android. The free plan includes voice, video, and text chat, community servers, and browser, desktop, and mobile access. Nitro Basic is $2.99 a month and includes 50 MB file uploads; Nitro is $9.99 a month and includes custom emoji and stickers, HD video streaming, and two Server Boosts. Discord says calls use end-to-end encryption, but messages are not encrypted and remain subject to its content moderation approach.
