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.
Table of Contents
- Powered by Lavaplayer
- Minimal CPU/memory footprint
- Twitch/YouTube stream support
- Event system
- Seeking
- Volume control
- REST API for resolving Lavaplayer tracks, controlling players, and more
- Statistics (good for load balancing)
- Basic authentication
- Prometheus metrics
- Docker images
- Plugin support (beta)
- Java 11* LTS or newer required.
- OpenJDK or Zulu running on Linux AMD64 is officially supported.
Support for Darwin (Mac), Windows AMD64, and Linux ARM (Raspberry Pi) is provided on a best-effort basis. This is dependent on Lavaplayer's native libraries.
Lavaplayer currently supports following architectures:
Darwin (M1 & Intel), Linux aarch32, Linux aarch64, Linux ARMv7+ 32/64, Linux ARMHF(v6) 32, Linux i386 32, Linux x86 64, Windows i386 32 and Windows x86 64
JDA-NAS(Native Audio Buffer) & the Timescale filter are currently not supported on following architectures:
Linux ARMHF(v6) 32 and Linux aarch32
Support for other JVMs is also best-effort. Periodic CPU utilization stats are prone not to work everywhere.
*Java 11 appears to have some issues with Discord's TLS 1.3. Java 14 has other undiagnosed HTTPS problems. Use Java 13. Docker images have been updated. See #258, #260

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
Docker images can be found under packages with old builds prior to v3.7.4 being available on Docker Hub.
Install Docker & Docker Compose
Create a docker-compose.yml with the following content:
version: "3.8"
services:
lavalink:
image: ghcr.io/lavalink-devs/lavalink:3 # pin the image version to Lavalink v3
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.
