# Run with the JAR

> Run the standalone Alginte fat JAR with Java, and expose it on a network safely.

Alginte also ships as a **single fat JAR** — the backend and the web UI in one file.
It requires a **Java 25** runtime.

```shell theme={null}
java -jar alginte.jar --spring.kafka.bootstrap-servers=<kafka-host>:9092
```

Then open [http://localhost:8888](http://localhost:8888).

## The bind-address boundary

<Warning>
  By default `server.address=localhost`, so a plain `java -jar` serves **only the local
  machine**. Overriding the bind address is the moment you take ownership of the security
  boundary — anyone who can reach the port has full control of every connected Kafka
  cluster unless you enable the [login](/operate/authentication).
</Warning>

To serve a trusted network, override the bind and put a reverse proxy (TLS termination,
network allow-listing) in front:

```shell theme={null}
java -jar alginte.jar \
  --server.address=0.0.0.0 \
  --spring.kafka.bootstrap-servers=<kafka-host>:9092
```

Or via the environment:

```shell theme={null}
SERVER_ADDRESS=0.0.0.0 \
SPRING_KAFKA_BOOTSTRAPSERVERS=<kafka-host>:9092 \
java -jar alginte.jar
```

## Configuration

Everything configurable via `application.properties` can be set on the command line
(`--property=value`) or through environment variables (Spring relaxed binding). See
[Configuration](/operate/configuration) for the properties that matter, and mount an
external file with `--spring.config.additional-location=` if you prefer a file over
flags.
