The best free GTmetrix alternatives are Google PageSpeed Insights, WebPageTest, Chrome DevTools Lighthouse and our own free website speed test. Each one measures page speed in a slightly different way, so the right choice depends on whether you want a quick score, a detailed waterfall or testing from different locations.
Key takeaways
- Google PageSpeed Insights is the best free option for a quick score plus real-user Core Web Vitals data.
- WebPageTest is the best free option for deep technical detail and testing from different locations.
- Chrome DevTools Lighthouse is best for testing pages before you publish them.
- Scores differ between tools, so pick one or two and compare results over time, not against each other.
Why look for a GTmetrix alternative?
People look for a GTmetrix alternative when they want a simpler report, fewer account limits, a different test location or a second opinion on their score. GTmetrix is a capable tool, but every speed test uses its own test conditions, so a second tool helps you confirm whether a problem is real.
What are the best free GTmetrix alternatives?
| Tool | Best for | Cost |
|---|---|---|
| Techsolution speed test | Quick free check of any URL | Free |
| Google PageSpeed Insights | Score plus real-user Core Web Vitals | Free |
| WebPageTest | Detailed waterfalls and test locations | Free tests, paid extras |
| Chrome DevTools Lighthouse | Testing pages before launch | Free |
| Pingdom | Ongoing site monitoring | Paid service |
1. Techsolution free website speed test
Our free page speed checker lets you enter any public URL and get a speed report without creating an account. It is a quick way to find the biggest issues on a page before you move to a more detailed tool.
2. Google PageSpeed Insights
Google PageSpeed Insights tests a URL on mobile and desktop and shows a Lighthouse performance score. When enough data exists, it also shows field data from real Chrome users, which is the data that reflects Core Web Vitals. It is the best starting point because it comes directly from Google.
3. WebPageTest
WebPageTest is a technical testing tool that shows detailed waterfall charts and lets you choose the test location, device and connection. It is useful when you need to see exactly which file slows a page down, or how a page loads for visitors in another country.
4. Chrome DevTools Lighthouse
Lighthouse is built into Chrome DevTools. It runs on your own computer, so you can test pages that are not public yet. Results depend on your device and browser extensions, so test in an incognito window for cleaner results.
5. Pingdom
Pingdom is a paid website monitoring service that also offers a speed test. It is more useful for tracking uptime and performance over time than for one-off checks.
GTmetrix vs PageSpeed Insights: what is the difference?
Both tools use Lighthouse to produce lab results, but they test from different servers and locations, with different settings. That is why the same page can show two different scores. PageSpeed Insights adds real-user field data when it is available, which is the data Google uses for Core Web Vitals. Use the lab score to find problems and the field data to confirm real impact.
How do you choose the right speed test tool?
- For a fast overall check, use our free speed test or PageSpeed Insights.
- For finding the exact slow file, use WebPageTest.
- For testing before launch, use Chrome DevTools Lighthouse.
- For long-term monitoring, use a monitoring service.
Whichever you choose, test the mobile version first and run the test two or three times. Our guide on why PageSpeed scores change between runs explains the reasons.
What should you do after running a speed test?
Fix the biggest issue in the report first, then re-test. Common wins include compressing images, enabling caching and removing unused scripts. Our guide on how to improve website speed walks through each fix step by step.
Frequently asked questions
Is there a free alternative to GTmetrix?
Yes. Google PageSpeed Insights, WebPageTest, Chrome DevTools Lighthouse and our free speed test are all free to use for testing a page.
Which speed test tool is the most accurate?
No single tool is the most accurate, because each tests under different conditions. Pick one or two tools and compare results over time rather than between tools.
Why is my score different in GTmetrix and PageSpeed Insights?
The tools test from different locations and with different settings, so scores differ. Small differences are normal. Large differences usually mean a slow server response or a problem that shows up only on one connection.
Do I need more than one speed test tool?
One is enough for routine checks. A second tool is useful when you need a detailed waterfall or want to confirm a result.
Which tool is best for Core Web Vitals?
Google PageSpeed Insights, because it shows real-user Core Web Vitals data from Chrome when enough data exists.
Conclusion
The best GTmetrix alternative depends on your goal. Use PageSpeed Insights or our free tool for a fast check, WebPageTest for detail and Lighthouse for pre-launch testing. Start with our free website speed test and re-test after every change.
