A free alternative to WebPageTest
A deep performance testing tool that loads your page on real devices from many locations, producing detailed waterfalls, filmstrips, and video of the load.
What WebPageTest does well
- The most detailed performance testing generally available — real devices, many locations, and configurable connection profiles.
- Filmstrip and video output showing exactly what a visitor sees while the page loads.
- Open source, with a free hosted tier.
Where it stops
- Performance only, entirely by design.
- The output rewards expertise — it's a measurement instrument, not a verdict.
What MyWebsiteScore adds
- A verdict rather than raw measurements — what to fix first, and why it matters.
- Search visibility, security, trust, and conversion checked alongside speed.
- A shareable report link and an embeddable score badge.
Which should you use?
When you're doing serious performance engineering and need to see precisely what loads and when, WebPageTest is the better instrument and it isn't close.
