sitewise-crawler 0.2.0

Advanced browser-activity capture, behavioral profiling, alerting and reporting library for Python.

Sitewise Crawler 🕷️🧠

Sitewise Crawler is an enterprise-grade Python library for browser-activity monitoring, behavioral intelligence, and automated risk reporting. It transforms raw URL streams into actionable psychological and productivity profiles.

🚀 Day 1: Integration Blueprint

If you are a developer integrating this into a new application, here is the standard workflow:

1. The Environment

The library requires a Groq API Key for behavioral analysis.

export GROQ_API_KEY="your_api_key_here"

2. Basic Usage (The "Hello World" of Intelligence)

import os
from sitewise_crawler import create_insight_engine, ProfileBlender, BehaviorProfileSnapshot

# 1. Initialize
engine = create_insight_engine(api_key=os.getenv("GROQ_API_KEY"))

# 2. Get a real-time risk assessment for a URL
risk_result = engine.quick_url_risk_sync("https://example.com")
print(f"Status: {risk_result['status']} | Category: {risk_result['category']}")

# 3. Blend into a user profile
# Start with an empty snapshot
profile = BehaviorProfileSnapshot(device_id="dev_001")
updated_profile = ProfileBlender.update_profile_from_risk(profile, risk_result)

print(f"New Productivity Score: {updated_profile.productivity_rating}")

🏗️ Core Concepts & DTOs

The library communicates via Data Transfer Objects (DTOs) implemented as Pydantic models. This ensures your backend and the library always speak the same language.

Model	Description	Key Fields
BehaviorProfileSnapshot	The state of a user's behavior.	productivity_rating, nsfw_probability, top_categories
URLRiskResult	The output of a single URL check.	status, risk_score, category, reason
SessionWindow	A discrete block of browsing time.	start_time, end_time, events, duration_seconds
Alert	A fired security or productivity event.	alert_type, severity, message, evidence

🧠 Deep Dive: Modules

InsightEngine (AI Analysis)

The InsightEngine handles both fast-path (heuristic) and deep-path (LLM) analysis.

• Fast Path: Uses a built-in dictionary of millions of domains for instant classification.
• Deep Path: Crawls the page content, cleans it using trafilatura, and uses Llama 3.3 to understand the intent.

SessionAnalyzer (Windowing)

Transforms a continuous stream of logs into sessions.

• Gap Detection: Automatically starts a new session if the user is idle for > 30 minutes.
• Aggregation: Computes session-level stats (e.g., "Most distracting hour").

AlertEngine (Custom Rules)

You can extend the alerting logic by adding your own rules.

from sitewise_crawler import BaseAlertRule, Alert, Severity

class MyCustomRule(BaseAlertRule):
    def evaluate(self, ctx):
        if ctx.total_url_count_last_hour > 100:
            return Alert(
                alert_type="excessive_browsing",
                severity=Severity.MEDIUM,
                message="User is browsing at an extreme rate."
            )
        return None

🎓 Academic & Institutional Value

This library was built to satisfy high academic and institutional standards:

1. Explainability (XAI): Every score or alert includes an evidence object, allowing admins to see why the AI flagged a user.
2. Efficiency: Uses Exponential Moving Averages (EMA) and Trend Velocity. Instead of re-calculating everything, it only processes the latest delta.
3. Privacy-First: The library only extracts the "Semantic Core" of pages, ignoring personal identifying information in headers/sidebars.

⚙️ Configuration

The CrawlerConfig allows fine-grained control:

Option	Default	Description
use_playwright	False	Set to True for JavaScript-heavy (SPA) sites.
max_depth	3	BFS depth for site discovery.
timeout_ms	30000	Network timeout per page.
rate_limit_delay	1.0	Seconds to wait between requests (politeness).
