This is a minimal UI that can spin up to test Haystack for your prototypes. It's based on streamlit and is very easy to extend for your purposes.

Execute in this folder:

streamlit run webapp.py

Requirements: This expects a running Haystack REST API at http://localhost:8000

Just run

docker-compose up -d

in the root folder of the Haystack repository. This will start three containers (Elasticsearch, Haystack API, Haystack UI). You can find the UI at http://localhost:8501
