We are excited to announce that Windel Solutions has open-sourced our internal diagnostic engine: the Core Web Vitals & Technical SEO Audit Toolkit.

The repository is officially public on GitHub:
👉 github.com/Windel-Solutions/core-web-vitals-audit-toolkit

Why We Built This

Modern B2B platforms and enterprise web architectures frequently struggle with crawl budget decay, render-blocking scripts, and DOM bloat.

While browser extensions and generic web crawlers provide high-level scores, engineering teams need programmatic, terminal-based telemetry that can run directly inside CI/CD pipelines or automated cron audits.

This toolkit provides zero-dependency Python inspection for:

  1. Server Response Latency (TTFB): Measuring exact network timing and isolating origin server processing delays.
  2. DOM Tree Node Density: Flagging excessive DOM complexity (over 800 nodes) that triggers Interaction to Next Paint (INP) failures.
  3. Third-Party Script Bloat: Tracking external JavaScript tags and CSS stylesheets that degrade mobile client rendering.
  4. Structured Data Validation: Confirming the presence and integrity of embedded JSON-LD schema graphs.

Quick Installation & Usage

You can clone and run the toolkit in under sixty seconds:

git clone https://github.com/Windel-Solutions/core-web-vitals-audit-toolkit.git cd core-web-vitals-audit-toolkit pip install -r requirements.txt python audit_toolkit.py https://yourdomain.com

JSON Output for Pipeline Automation: 

python audit_toolkit.py https://yourdomain.com --json audit_report.json
