A standalone audio sending node based on Lavaplayer and Koe. Allows for sending audio without it ever reaching any of your shards.
Being used in production by FredBoat, Dyno, LewdBot, and more.
A basic example bot is available.
Warning
Lavalink v4 is now in beta! See here for more information.
Table of Contents
- Powered by Lavaplayer

Or alternatively, you can create your own client library, following the implementation documentation.
Any client libraries marked with Unmaintained have been marked as such as their repositories have not received any commits for at least 1 year since time of checking,
however they are listed as they may still support Lavalink, and/or have not needed maintenance, however keep in mind that compatibility and full feature support is not guaranteed.
The server configuration is done in application.yml. You can find an example configuration here.
Alternatively, you can also use environment variables to configure the server. The environment variables are named the same as the keys in the application.yml file, but in uppercase and with . replaced with _. For example, server.port becomes SERVER_PORT.
For arrays, the index is appended to the key, starting at 0. For example, LAVALINK_PLUGINS_0_DEPENDENCY refers to the dependency key of the first plugin.

Put an application.yml file in your working directory. (Example here)
Run with java -jar Lavalink.jar from the same directory
If you're using a Systemd-based Linux distribution you may want to install Lavalink as a background service. You will need to create a lavalink.service file inside /usr/lib/systemd/system. Create the file with the following template (replacing the values inside the <> brackets):
[Unit]
# Describe the service
Description=Lavalink Service
# Configure service order
After=syslog.target network.target
[Service]
# The user which will run Lavalink
User=<usr>
# The group which will run Lavalink
Group=<usr>
# Where the program should start
WorkingDirectory=</home/usr/lavalink>
# The command to start Lavalink
ExecStart=java -Xmx4G -jar </home/usr/lavalink>/Lavalink.jar
# Restart the service if it crashes
Restart=on-failure
# Delay each restart by 5s
RestartSec=5s
[Install]
# Start this service as part of normal system start-up
WantedBy=multi-user.targetTo initiate the service, run
sudo systemctl daemon-reload
sudo systemctl enable lavalink
sudo systemctl start lavalinkIn addition to the usual log files, you can also view the log with sudo journalctl -u lavalink.
Docker images can be found under packages with old builds prior to v3.7.4 being available on Docker Hub.
There are 2 image variants Ubuntu and Alpine, the Alpine variant is smaller and can be used with the -alpine suffix, for example ghcr.io/lavalink-devs/lavalink:3-alpine.
Install Docker & Docker Compose
Create a docker-compose.yml with the following content:
version: "3.8"
services:
lavalink:
image: ghcr.io/lavalink-devs/lavalink:4 # pin the image version to Lavalink v4
container_name: lavalink
restart: unless-stopped
environment:
- _JAVA_OPTIONS=-Xmx6G # set Java options here
- SERVER_PORT=2333 # set lavalink server port
- LAVALINK_SERVER_PASSWORD=youshallnotpass # set password for lavalink
volumes:
- ./application.yml:/opt/Lavalink/application.yml # mount application.yml from the same directory or use environment variables
- ./plugins/:/opt/Lavalink/plugins/ # persist plugins between restarts, make sure to set the correct permissions (user: 322, group: 322)
networks:
- lavalink
expose:
- 2333 # lavalink exposes port 2333 to connect to for other containers (this is for documentation purposes only)
ports:
- 2333:2333 # you only need this if you want to make your lavalink accessible from outside of containers
networks:
lavalink: # create a lavalink network you can add other containers to, to give them access to Lavalink
name: lavalinkRun docker compose up -d. See Docker Compose Up
If your bot also runs in a docker container you can make that container join the lavalink network and use lavalink (service name) as the hostname to connect.
