Hangar platform guide
Run your game as a Discord Activity.
Hangar prepares your app to run as a Discord Activity, the embedded apps that open inside Discord voice channels. It sets up the Embedded App SDK and OAuth wiring so the build matches what Discord's runtime expects.
A Discord Activity is a web app that runs inside Discord, embedded in a voice channel through the Embedded App SDK. The app loads in an iframe and talks to Discord through the SDK for the channel context, the participants and authentication. Because it is web, the same build runs across Discord's desktop, web and mobile clients.
Activities open from the activity menu in a voice channel, so they are shared by default: everyone in the channel can join the same session. Distribution runs through the App Directory and the in-client surface rather than an external store, and Discord OAuth2 handles login and player identity. In-app purchases are available through Discord's systems for apps that sell.

Common questions
What is a Discord Activity?
A web app embedded inside a Discord voice channel through the Embedded App SDK. It runs in an iframe, reads the channel and participant context from the SDK, and works across Discord's desktop, web and mobile clients from one build.
How do players start an Activity?
From the activity menu in a voice channel. Activities are multiplayer by default, so everyone in the channel can join the same session, which makes the channel itself the distribution surface.
What does Hangar set up for Discord?
Hangar wires the Embedded App SDK and the Discord OAuth2 flow, and prepares the iframe build to Discord's runtime, keeping it aligned with the other platforms you target.
