Steps:
Scenario: Agent with external MCP server tools
Example: Using mcp-server-fetch to summarize tech news
# High availability deployment
apiVersion: apps/v1
kind: Deployment
metadata:
name: langflow
spec:
replicas: 3
template:
spec:
containers:
- name: langflow
image: langflowai/langflow:latest
env:
- name: LANGFLOW_AUTO_LOGIN
value: "false"
- name: LANGFLOW_SECRET_KEY
valueFrom:
secretKeyRef:
name: langflow-secrets
key: secret-key
# Generate API key via CLI
uv run langflow api-key
# Generate secure secret key
python3 -c "from secrets import token_urlsafe; print(f'LANGFLOW_SECRET_KEY={token_urlsafe(32)}')"
# Use in requests
curl -X POST "https://your-instance/api/v1/run" \
-H "x-api-key: $LANGFLOW_API_KEY" \
-H "Content-Type: application/json" \
-d '{"flow_id": "abc123", "inputs": {...}}'
Create Python component:
from langflow.custom import Component
from langflow.io import MessageTextInput, Output
from langflow.schema import Message
class CustomGreetingComponent(Component):
display_name = "Custom Greeting"
description = "Greets users with custom message"
inputs = [
MessageTextInput(
name="user_name",
display_name="User Name",
info="Name to greet"
)
]
outputs = [
Output(display_name="Greeting", name="output", method="greet")
]
def greet(self) -> Message:
name = self.user_name
return Message(text=f"Hello, {name}! Welcome to Langflow.")
Scenario: Research agent + summarization agent
# Disable auto-login for multi-user environments
export LANGFLOW_AUTO_LOGIN=False
# Set custom secret key (required for production)
export LANGFLOW_SECRET_KEY=$(python3 -c "from secrets import token_urlsafe; print(token_urlsafe(32))")
# Configure CORS (specific origins only)
export LANGFLOW_CORS_ORIGINS="https://yourdomain.com,https://app.yourdomain.com"

Enterprise Features:
Quick Start (No Installation):
# Run directly with uvx (no local installation)
uvx openrag
# Run specific version
uvx --from openrag==0.2.0 openrag
Python Package Installation:
# Create project with uv
uv init my-rag-app
cd my-rag-app
# Add OpenRAG
uv add openrag
# Launch TUI
uv run openrag
Docker/Podman Deployment:
# OpenRAG automatically manages containers
# See: https://docs.openr.ag/docker
Managed Containers (Recommended):
Self-Managed Containers:
1. Enterprise Document Q&A
2. Research Assistant
3. Customer Support Knowledge Base
4. Legal Document Analysis
| Feature | Langflow | OpenRAG |

When to Use OpenRAG:
When to Use Langflow Directly:
December 2025 Release:
~/.openrag)# 1. Quick start (runs in TUI)
uvx openrag
# 2. Follow TUI prompts to:
# - Configure OpenSearch
# - Set up LLM provider (OpenAI, Anthropic, etc.)
# - Start services
# 3. Access web interface
# Default: http://localhost:3000
# 4. Upload documents and start chatting
Storage Location: ~/.openrag/
Environment Variables:
# LLM Provider
OPENAI_API_KEY=your_key
ANTHROPIC_API_KEY=your_key
# OpenSearch
OPENSEARCH_PASSWORD=secure_password
# Langfuse (Optional)
LANGFUSE_PUBLIC_KEY=your_key
LANGFUSE_SECRET_KEY=your_key
Common Issues:
Container Startup Failures
