Frequently Asked Questions

Common questions about our free web tools

Is WebHangar completely free to use?

Yes, all 80+ tools on WebHangar.net are completely free to use. There are no hidden costs, premium tiers, or usage limits. You can test website speed, check SSL certificates, and use all other tools without any payment.

Do I need to create an account?

No registration is required for most tools. You can start testing immediately. However, creating a free account allows you to save your test history and access your results later.

How accurate is the Page Speed Test?

Our Page Speed Test uses Google Lighthouse, the same engine that powers Chrome DevTools and PageSpeed Insights. Results include Core Web Vitals (LCP, FID, CLS), performance score, and detailed optimization recommendations.

What's the difference between Page Speed Test and Waterfall Analysis?

Page Speed Test provides an overall performance score and Core Web Vitals metrics. Waterfall Analysis shows a detailed timeline of how each resource (HTML, CSS, JS, images) loads, helping identify specific bottlenecks and render-blocking resources.

Is my data secure?

Yes, we take privacy seriously. Many tools work entirely in your browser without sending data to our servers. For tools that require server processing (like Page Speed Test), we don't store your results permanently unless you're logged in.

Can I use these tools for commercial projects?

Absolutely! All tools are free for both personal and commercial use. Whether you're a freelancer, agency, or enterprise, you can use WebHangar to test and optimize your clients' websites.

WebHangar: Your Complete Toolkit for Website Testing & Optimization

WebHangar.net is a comprehensive platform offering 80+ free online tools designed specifically for web developers, SEO specialists, system administrators, and digital marketers. Whether you need to test website speed, analyze SEO performance, check SSL certificates, or convert data formats, our tools provide professional-grade results without any cost or registration requirements.

Website Performance Testing

Our Page Speed Test tool uses Google Lighthouse to provide accurate performance metrics including Core Web Vitals (Largest Contentful Paint, First Input Delay, Cumulative Layout Shift). Unlike basic speed checkers, we provide detailed optimization recommendations to help you improve your site's loading time and user experience.

The Waterfall Analysis tool visualizes exactly how your page loads, showing each resource request in a timeline format. This helps identify render-blocking scripts, slow API calls, and opportunities for optimization that aren't visible in standard speed tests.

Security & SSL Analysis

Website security is crucial for user trust and SEO rankings. Our SSL Certificate Checker verifies your certificate's validity, expiration date, issuer information, and security configuration. The Security Headers Analyzer checks for important HTTP security headers like Content-Security-Policy, X-Frame-Options, and HSTS.

SEO Tools for Better Rankings

Improve your search engine visibility with our suite of SEO tools. The Meta Tag Analyzer examines your page's title, description, and keywords for optimal length and relevance. Our Open Graph Checker ensures your content looks perfect when shared on social media platforms like Facebook, Twitter, and LinkedIn.

Developer Utilities

Save time with our collection of developer tools including JSON formatters, Base64 encoders, hash generators, and code converters. The JSON to Code tool converts JSON data to Python, JavaScript, TypeScript, Go, and Rust code instantly. Our Cron Expression Generator helps you build and understand complex cron schedules.
