Ollama4j Web UI

A web UI for Ollama written in Java using Spring Boot and Vaadin framework and Ollama4j.

The goal of the project is to enable Ollama users coming from Java and Spring background to have a fully functional web UI.

This project focuses on the raw capabilities of interacting with various models running on Ollama servers.

Requirements

Running the application

Via Docker

If you already have a Ollama service running, the easiest way to get started is by using Docker by pointing to the host address of Ollama. Find the image tags here.

Run the Docker container by issuing this in your terminal:

docker run -it \
  -p 9090:8080 \
  -e OLLAMA_HOST_ADDR='http://192.168.10.1:11434' \
  amithkoujalgi/ollama4j-web-ui

Via Docker Compose

If you want to start the Ollama service and the Ollama Web UI as Docker containers, create a file called docker-compose.yaml and add the following contents in it:

services:

  ollama:
    image: ollama/ollama
    ports:
      - "11434:11434"
    volumes:
      - ~/ollama:/root/.ollama
    shm_size: 512mb

  ollama4j-web-ui:
    image: amithkoujalgi/ollama4j-web-ui
    ports:
      - "9090:8080"
    environment:
      OLLAMA_HOST_ADDR: 'http://ollama:11434'

Then open up your terminal and then type in:

docker-compose -f /path/to/your/docker-compose.yaml up

And then you access the Ollama4j Web UI on http://localhost:9090.

As a standalone JAR

Download the latest version from here.

Or, you could download it via command-line. Just make sure to specify the version you want to download.

VERSION=0.0.1; wget https://github.com/ollama4j/ollama4j-web-ui/releases/download/$VERSION/ollama4j-web-ui-$VERSION.jar

Configure

Set environment variables.

export SERVER_PORT=8080
export OLLAMA_HOST_ADDR=http://localhost:11434

Or, if you would want to override the base config file, create a file application.properties and add the following configuration. Update the values of server.port and ollama.url according to your needs.

server.port=8080
logging.level.org.atmosphere = warn

spring.mustache.check-template-location = false
spring.servlet.multipart.max-file-size=50MB
spring.servlet.multipart.max-request-size=50MB

vaadin.launch-browser=true
vaadin.whitelisted-packages = com.vaadin,org.vaadin,dev.hilla,io.github.ollama4j

ollama.url=http://localhost:11434
ollama.request-timeout-seconds=120

Run the app

java -jar ollama4j-web-ui-$VERSION.jar \
  --spring.config.location=/path/to/your/application.properties

Then open http://localhost:8080 in your browser to access the Ollama4j Web UI.

Screenshots

Improvements

• Show errors on the UI. For example, io.github.ollama4j.exceptions.OllamaBaseException: model "llama3" not found, try pulling it first.
• Settings pane for configuring default params such as top-p, top-k, etc.
