Spacebar/server is a Discord backend re-implementation and extension. We aim to reverse engineer and add additional features to the Discord backend, while remaining completely backwards compatible with existing bots, applications, and clients.

This repository contains:

• API Request/Response Types
• Spacebar HTTP API server
• WebSocket Gateway server
• HTTP CDN server
• WebRTC server
• Utility and Database Models
• Spacebar Admin API (C#)
• HTTP CDN server (C#)
• Various other C# utilities

And with documentation on how to set up your own server here, docs to set up either client here, and docs about bots here

You should be able to use any client designed for Discord.com to connect to a Spacebar instance. However, some incompatibilities still exist between Spacebar and Discord. For this reason, not every client will connect.
We recommend using Fermo as a solid starting point on your adventure in the SpaceBar! You can explore other clients with the Spacebar Explorer.
