Discord4J is a fast, reactive JVM library for building Discord bots using the official Discord Bot API, built on Reactor and Netty. It provides a modular, non-blocking REST and WebSocket wrapper with automatic rate limiting and reconnection strategies.
Use cases
- build a discord bot in java
- create a discord bot with kotlin
- respond to discord messages with a bot
- handle discord slash commands
- connect to discord gateway websocket events
- make discord rest api calls with rate limiting
- develop a reactive discord bot on the jvm
When to choose
- you are building a Discord bot in Java, Kotlin, or another JVM language
- you want a reactive, non-blocking API with automatic rate limiting and reconnection
- you need fine-grained, modular control over which Discord API components you use
- you want a mature, well-documented wrapper with active releases
When to avoid
- you are writing bots in Python, JavaScript, or other non-JVM languages
- you prefer a simple blocking API without reactive programming concepts
- you need a full bot framework with command handlers and plugins rather than a low-level API wrapper
- you want a turnkey hosted bot solution
