Speed Tester by Omar — Website Speed, SEO & Security

About

Test any website's speed, SEO, and security in ONE CLICK — right from your Chrome toolbar.

Speed Tester by Omar runs a complete website audit on the page you're viewing in 30-60 seconds. You get five score categories, real Core Web Vitals from Google's CrUX dataset, key performance metrics, and a link to a full detailed report — all in a clean popup that doesn't slow your browser down.

No signup. No API keys. No upsells. Free forever.

WHAT YOU GET
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

⚡ ONE-CLICK TESTING
Click the toolbar icon, click "Test Speed Now". That's it. You get scores in 30-60 seconds — no configuration, no setup, no learning curve.

📊 FIVE SCORE CATEGORIES
Performance, Mobile, Security, SEO, and Best Practices — all scored 0-100 with color-coded indicators (green / amber / red). One look tells you everything.

🌐 REAL CORE WEB VITALS
LCP, INP, CLS, and TTFB — pulled from Google's Chrome User Experience Report (CrUX), which contains real-world data from actual users visiting your site. Not synthetic estimates from your own browser.

🖱️ RIGHT-CLICK ANY LINK
Want to test a competitor's homepage without leaving your tab? Right-click any link → "Test this link's speed". Done.

📋 TEST HISTORY
Your last 8 tests are saved locally on your device, so you can re-open any report with a single click. Click any item to jump back to the full report.

🔒 PRIVACY-FIRST DESIGN
The extension only requests three permissions:
• activeTab — to read the URL of the page you're testing (only when you click)
• storage — to save your test history locally on YOUR device
• contextMenus — for the right-click menu

We do NOT read page contents, browsing history, cookies, or any personal data. We do NOT track you. We do NOT show ads. We do NOT sell or share data. Open source, MIT licensed.

🚀 TESTS RUN ON OUR SERVERS
Unlike Lighthouse or DevTools, Speed Tester doesn't run tests in your browser — it sends the URL to our backend and runs the analysis there. Your CPU stays free, your tabs stay snappy, and you get consistent results regardless of your machine or network conditions.

🆓 FREE FOREVER
No premium tier. No paid features. No "trial expires" emails. No API keys to manage. Free is the only tier.

PERFECT FOR
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

✓ Web developers verifying performance after deploys
✓ Freelancers running quick audits during sales calls
✓ SEO consultants checking Core Web Vitals on competitor sites
✓ Site owners who want quick health checks without opening a dozen tabs
✓ Agency teams who need consistent results across machines
✓ Anyone tired of bouncing between PageSpeed Insights, GTmetrix, and security checkers

HOW IT COMPARES
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

vs Built-in Chrome DevTools (Lighthouse):
DevTools runs Lighthouse synchronously in YOUR browser, which freezes the tab and gives lab data only. Speed Tester runs tests on our backend with consistent network conditions and pulls real-world Core Web Vitals — much closer to what your actual users experience.

vs PageSpeed Insights (web app):
PageSpeed Insights requires you to copy-paste URLs into a browser tab. Speed Tester is one click on the page you're already viewing. Plus you get more categories (security, best practices) and a clean unified popup.

vs GTmetrix / Pingdom / WebPageTest:
Those tools are powerful but require accounts, queue tests, and live in their own websites. Speed Tester gives you the essentials in seconds, right where you already are.
