Install

Run these commands on your server:

# Langflow — official image (docs.langflow.org → Deploy Langflow on Docker), pinned to the 1.12.3 release
# the image sets LANGFLOW_AUTO_LOGIN=false, so a superuser password is required; generate one and keep it
export LANGFLOW_SUPERUSER_PASSWORD="$(openssl rand -hex 16)" && echo "$LANGFLOW_SUPERUSER_PASSWORD"
docker run -d --name langflow --restart unless-stopped \
  -p 7860:7860 \
  -e LANGFLOW_SUPERUSER=admin -e LANGFLOW_SUPERUSER_PASSWORD \
  -e LANGFLOW_CONFIG_DIR=/app/langflow -v langflow-data:/app/langflow \
