Expose your Discord presence and activities to a RESTful API
...The public service can be used quickly by joining the Lanyard Discord server, but the project also supports self-hosting. It includes a real-time key-value store that can be updated through the bot or API and emitted through presence updates. Developers can subscribe to one user, multiple users, or all monitored users through its socket protocol. Lanyard is especially useful for personal websites, GitHub profile widgets, dashboards, and real-time presence visualizations.
