Javacord Latest version Latest JavaDocs Javacord Wiki Javacord Discord server

An easy to use multithreaded library for creating Discord bots in Java.

Javacord is a modern library that focuses on simplicity and speed 🚀. By reducing itself to standard Java classes and features like Optionals and CompletableFutures, it is extremely easy to use for every Java developer, as it does not require you to learn any new frameworks or complex abstractions. It has rich documentation and an awesome community on Discord that loves to help with any specific problems and questions.

🎉 Basic Usage

The following example logs the bot in and replies to every "!ping" message with "Pong!".

public class MyFirstBot {

    public static void main(String[] args) {
        // Insert your bot's token here
        String token = "your token";

        DiscordApi api = new DiscordApiBuilder().setToken(token).login().join();

        // Add a listener which answers with "Pong!" if someone writes "!ping"
        api.addMessageCreateListener(event -> {
            if (event.getMessageContent().equalsIgnoreCase("!ping")) {

        // Print the invite url of your bot
        System.out.println("You can invite the bot by using the following url: " + api.createBotInvite());


More sophisticated examples can be found at the end of the README. You can also check out the example bot for a fully functional bot.

📦 Download / Installation

The recommended way to get Javacord is to use a build manager, like Gradle or Maven.
If you are not familiar with build managers, you can follow this setup guide or download Javacord directly from GitHub.

Javacord Dependency


repositories { mavenCentral() }
dependencies { implementation 'org.javacord:javacord:3.0.6' }




libraryDependencies ++= Seq("org.javacord" % "javacord" % "3.0.6")

Optional Logger Dependency

Any Log4j-2-compatible logging framework can be used to provide a more sophisticated logging experience with being able to configure log format, log targets (console, file, database, Discord direct message, ...), log levels per class, and much more.

For example, Log4j Core in Gradle

dependencies { runtimeOnly 'org.apache.logging.log4j:log4j-core:2.11.0' }

Take a look at the logger configuration wiki article for further information.

🔧 IDE Setup

If you have never used Gradle or Maven before, you should take a look at one of the setup tutorials:

📋 Version Numbers

The version number has a 3-digit format: major.minor.trivial

🔨 Deprecation Policy

A method or class that is marked as deprecated can be removed with the next minor release (but it will usually stay for several minor releases). A minor release might remove a class or method without having it deprecated, but we will do our best to deprecate it before removing it. We are unable to guarantee this though, because we might have to remove / replace something due to changes made by Discord, which we are unable to control. Usually you can expect a deprecated method or class to stay for at least 6 months before it finally gets removed, but this is not guaranteed.

🥇 Large Bots Using Javacord

Javacord is used by many large bots. Here are just a few of them:

🙌 More Examples

Using the MessageBuilder 🛠

The following example uses the built-in MessageBuilder. It is very useful to construct complex messages with images, code-blocks, embeds, or attachments.

new MessageBuilder()
  .append("Look at these ")
  .append("awesome", MessageDecoration.BOLD, MessageDecoration.UNDERLINE)
  .append(" animal pictures! 😃")
  .appendCode("java", "System.out.println(\"Sweet!\");")
  .addAttachment(new File("C:/Users/JohnDoe/Pictures/kitten.jpg"))
  .addAttachment(new File("C:/Users/JohnDoe/Pictures/puppy.jpg"))
  .setEmbed(new EmbedBuilder()
        .setDescription("Really cool pictures!")

Listeners in Their Own Class 🗃

All the examples use inline listeners for simplicity. For better readability it is also possible to have listeners in their own class:

public class MyListener implements MessageCreateListener {

    public void onMessageCreate(MessageCreateEvent event) {
        Message message = event.getMessage();
        if (message.getContent().equalsIgnoreCase("!ping")) {

api.addListener(new MyListener());

For commands, you have the option of using one of the many existing command frameworks such as

or even write your own!

Attach Listeners to Objects 📌

You can even attach listeners to objects. Let's say you have a very sensitive bot. As soon as someone reacts with a 👎 within the first 30 minutes of message creation, it deletes its own message.

api.addMessageCreateListener(event -> {
    if (event.getMessageContent().equalsIgnoreCase("!ping")) {
        event.getChannel().sendMessage("Pong!").thenAccept(message -> {
            // Attach a listener directly to the message
            message.addReactionAddListener(reactionEvent -> {
                if (reactionEvent.getEmoji().equalsEmoji("👎")) {
            }).removeAfter(30, TimeUnit.MINUTES);

The result then looks like this:

Creating a Temporary Voice Channel 💣🎧

This example creates a temporary voice channel that gets deleted when the last user leaves it or if nobody joins it within the first 30 seconds after creation.

Server server = ...;
ServerVoiceChannel channel = new ServerVoiceChannelBuilder(server)

// Delete the channel if the last user leaves
channel.addServerVoiceChannelMemberLeaveListener(event -> {
    if (event.getChannel().getConnectedUserIds().isEmpty()) {

// Delete the channel if no user joined in the first 30 seconds 
api.getThreadPool().getScheduler().schedule(() -> {
    if (channel.getConnectedUserIds().isEmpty()) {
}, 30, TimeUnit.SECONDS);

Note: You should also make sure to remove the channels on bot shutdown (or startup)
