Quick Start - Alginte

The fastest way to try Alginte is the Docker image. You need a reachable Kafka broker.

Run the image

Point Alginte at your broker and expose the UI on port 8888:

docker run -p 8888:8888 \
  -e SPRING_KAFKA_BOOTSTRAPSERVERS=<kafka-host>:9092 \
  alginte/alginte:latest

Open the UI

Browse to http://localhost:8888.

Alginte fails fast on startup if the broker is unreachable — this is by design. Inside a container, localhost is the container itself, so SPRING_KAFKA_BOOTSTRAPSERVERS=localhost:9092 will not find a broker on your host. Use a hostname/IP reachable from the container, or join the broker’s Docker network — see Run with Docker.

Prefer no container?

Download the standalone fat JAR and run it with Java 25:

java -jar alginte.jar --spring.kafka.bootstrap-servers=<kafka-host>:9092

By default this serves only your local machine (server.address=localhost). See Run with the JAR to expose it on a network safely.

Next steps

Configuration

Wire up Schema Registry, Connect, and ksqlDB.

Authentication

Turn on login before exposing Alginte on a network.
