## What it is
Spacebar is a free, open-source, self-hostable re-implementation of Discord's client-server API, providing chat, voice, and video communication. It aims for feature parity with discord.com so existing Discord clients, bots, and applications work with minimal changes.

## Use cases
- self-host a Discord-compatible chat server
- run a private chat platform with voice and video
- use existing Discord bots and clients on my own server
- migrate away from discord.com while keeping familiar tooling
- host a privacy-focused community chat with full data control
- extend a chat platform with custom plugins and themes

## When to choose
- you want full control over your chat data and configuration
- you need Discord API compatibility for existing clients and bots
- you want a FOSS, auditable communication platform
- you need self-hosting with customizable limits and features

## When to avoid
- you need to interoperate directly with discord.com users or Nitro features
- you want a fully polished, production-proven platform with complete Discord parity today
- you prefer a managed hosted service with no server maintenance
