netpulse-discovery 0.1.5

High-speed network discovery and drift analysis engine

NetPulse Discovery

NetPulse Discovery is a high-performance, asynchronous network mapping and drift-analysis engine. By offloading packet-level networking to a compiled Rust core, it achieves near wire-speed execution while maintaining a flexible, developer-friendly Python API.

🚀 Key Features

• Blazing Fast Scans: Leverages libpcap and raw sockets in Rust to execute ARP and ICMP sweeps orders of magnitude faster than standard Python libraries.
• Asynchronous Port Scanning: Native asyncio TCP connect scanner that can check hundreds of ports across multiple devices concurrently.
• Drift Detection: Built-in intelligence to compare historical scans and calculate exact topological drift (e.g., "Host 192.168.1.5 went offline").
• MAC Vendor Resolution: Automatically translates hardware MAC addresses into human-readable manufacturer names.
• Standalone API & CLI: Usable as a Python library, a Typer-powered CLI, or a FastAPI REST microservice.

📦 Installation

NetPulse Discovery is distributed as a pre-compiled binary wheel. It is entirely self-sufficient and requires no Rust compiler or external dependencies to install!

pip install netpulse-discovery

⚡ Quickstart

As a CLI Tool

The standalone CLI returns structured JSON output perfect for piping into jq or other tools. You can also export directly to files!

[!IMPORTANT] Multiplatform Execution: Low-level network scanning requires elevated privileges.

• Linux / macOS: Prefix your commands with sudo
• Windows: Open an Administrator Command Prompt or PowerShell session to execute.

# Scan a network
sudo netpulse-discovery scan 192.168.1.0/24 --timeout 500

# Export results directly to a file
sudo netpulse-discovery scan 192.168.1.0/24 --output results.json
sudo netpulse-discovery scan 192.168.1.0/24 --output results.yaml
sudo netpulse-discovery scan 192.168.1.0/24 --output results.txt

# Calculate Network Drift from two exported JSON files (No sudo required)
netpulse-discovery drift old_results.json results.json --output drift_report.yaml

# Run Continuous Daemon Mode with Webhook Alerting
sudo netpulse-discovery watch 192.168.1.0/24 --interval 300 --webhook https://hooks.slack.com/services/T000/B000/XXX

# Generate an Ansible Infrastructure-as-Code Inventory from a live scan
sudo netpulse-discovery generate-inventory 192.168.1.0/24 --format ansible --output hosts.yaml

As a Standalone REST API

You can spin up a dedicated, hyper-fast FastAPI server instantly:

netpulse-discovery serve --port 8000

Then send requests to http://localhost:8000/discovery/scan or http://localhost:8000/discovery/drift/compare.

As a Python Library

Embed the high-performance engine directly into your own applications:

import asyncio
from netpulse.discovery.services.discovery import DiscoveryService
from netpulse.discovery.models.discovery import DiscoveryMethod

async def main():
    service = DiscoveryService()
    # Scans the network using ARP resolution
    result = await service.discover_network(
        "10.0.0.0/24", 
        methods=[DiscoveryMethod.ARP]
    )
    
    for device in result.devices:
        print(f"[{device.ip}] {device.mac} - {device.vendor}")

asyncio.run(main())
