LLM Router Web

Web interface for managing LLM Router configurations and text anonymization.

Overview

llm_router_web provides two Flask-based web applications:

1. Config Manager – Manage LLM Router model configurations with multi-user support
2. Anonymizer – Web UI for text anonymization and chat with anonymization

Features

Config Manager (app_cfg_manager)

• User Management: Admin panel, authentication, role-based access
• Project Management: Organize configurations into projects
• Model Configuration:
  • Create, edit, import/export configurations (JSON)
  • Manage models across families (Google, OpenAI, Qwen)
  • Configure providers (API hosts, tokens, weights, input sizes)
  • Version control with restore capability
• Active Model Selection: Choose which models to activate

Anonymizer (app_anonymizer)

• Text Anonymization: Multiple algorithms (fast, GenAI, PrivMasker)
• Chat Interface: Interactive chat with optional anonymization
• Model Selection: Browse and select available LLM models
• Real-time Processing: Direct integration with LLM Router API

Installation

pip install -r requirements.txt

Requirements

• Flask
• Flask-SQLAlchemy
• Gunicorn

Usage

Config Manager

Run with Gunicorn (recommended):

./run-configs-manager.sh

Run directly:

python app_cfg_manager.py

Configuration (environment variables):

• LLM_ROUTER_WEB_CFG_HOST – Bind address (default: 0.0.0.0)
• LLM_ROUTER_WEB_CFG_PORT – Port (default: 8081)
• LLM_ROUTER_WEB_CFG_DEBUG – Debug mode (default: true)

First-time setup:

1. Access the web interface
2. Create initial admin account via setup page
3. Log in and start managing configurations

Default URL: http://localhost:8081

Anonymizer

Run with Gunicorn (recommended):

./run-anonymizer.sh

Run directly:

python app_anonymizer.py

Configuration (environment variables):

• LLM_ROUTER_WEB_ANO_HOST – Bind address (default: 0.0.0.0)
• LLM_ROUTER_WEB_ANO_PORT – Port (default: 8082)
• LLM_ROUTER_WEB_ANO_DEBUG – Debug mode (default: true)
• LLM_ROUTER_HOST – LLM Router API endpoint (default: http://192.168.100.65:8080)
• LLM_ROUTER_GENAI_MODEL_ANONYMISATION – Model for GenAI anonymization (default: gtp-oss:120b)

Default URL: http://localhost:8082/anonymize

Database

Config Manager uses SQLite with SQLAlchemy ORM:

• Models: User, Project, Config, Model, Provider, ActiveModel, ConfigVersion
• Location: instance/configs.db (auto-created on first run)
• Version Control: Automatic configuration snapshots on changes

Security

• Password hashing via Werkzeug
• Session-based authentication
• Role-based access control (admin/user)
• User account blocking capability
• Per-user project isolation

Notes

• Config Manager requires initial admin setup on first run
• Anonymizer requires a running LLM Router instance
• Both apps run independently on different ports
• Configurations are stored in SQLite database (Config Manager only)
• All configuration changes are versioned and can be restored
