As a webmaster or developer, you know the drill: checking DNS records in one tool, SSL certificates in another, running separate tests for security headers, SEO, and performance. It's tedious, time-consuming, and scattered across dozens of browser tabs.

Webmaster Domain Toolkit changes that. All 9 tools are accessible via a sleek tab bar, letting you switch between analyses instantly. No more juggling browser windows or remembering different website URLs.

All 9 Tools at Your Fingertips

Each tool is accessible via a sleek tab bar, letting you switch between analyses instantly.

🌐

DNS Health Checker

Analyze A, AAAA, MX, TXT, NS, and CNAME records. Validates SPF and DMARC email security configurations.

🔒

SSL Certificate Analyzer

Inspect certificates, protocols, cipher suites, and detect vulnerabilities. Get a security grade from A+ to F.

🛡️

Security Headers Analyzer

Evaluate CSP, HSTS, X-Frame-Options, and other critical HTTP security headers.

Web Vitals Auditor

Measure Core Web Vitals (LCP, FID, CLS) and performance metrics using Google PageSpeed Insights.

🔍

SEO Meta Validator

Validate meta tags, heading hierarchy, Schema.org markup, Open Graph, and Twitter Cards.

📡

API Security Tester

Test REST and GraphQL endpoints for CORS issues, authentication problems, and security misconfigurations.

⚠️

Mixed Content Scanner

Identify HTTP resources loaded on HTTPS pages that could trigger browser warnings.

💻

Technology Stack Detector

Discover frameworks, servers, CDN providers, analytics tools, and CMS platforms in use.

Accessibility Checker

Evaluate WCAG 2.1 compliance and identify accessibility issues affecting users.

Instant Health Scores

Every scan generates a clear 0-100 health score with a letter grade (A+ through F). Quickly understand the state of your domain at a glance, then drill down into specific issues.

A+

Score: 100/100 - Excellent

Your domain is perfectly configured. SPF, DMARC (with reject policy), and MX records all properly set up.

F

Score: 10/100 - Critical Issues

Missing CSP and HSTS headers. Grade capped at B maximum until these critical security headers are added.

How Scoring Works

Each tool uses domain-specific scoring criteria. For example, the DNS Health Checker deducts points for:

  • Missing SPF record (-20 points)
  • Missing DMARC record (-30 points)
  • DMARC policy set to "none" (-10 points)
  • Missing MX records (-20 points)
  • Missing A record (-10 points)

AI-Powered Troubleshooting

Here's where Webmaster Domain Toolkit really shines. After every scan, you can generate a detailed AI prompt that summarizes your findings and asks the right questions.

Example Generated Prompt (Security Headers)

I have a security headers analysis for "https://example.com".

Overall Score: 10/100 (Grade: F)
Note: Grade capped at B due to Missing CSP and HSTS headers

## Headers Present:
- **Server** ✓
  Value: `cloudflare`

## Missing Headers:
- Strict-Transport-Security (HSTS) (25 points)
- Content-Security-Policy (CSP) (25 points)
- X-Content-Type-Options (10 points)
- X-Frame-Options (15 points)
- Referrer-Policy (5 points)

Can you provide the specific headers I should add to fix these issues?

Copy this prompt into ChatGPT, Claude, or any AI assistant, and get specific, actionable recommendations tailored to your exact configuration.
