Is Lighthouse the same thing?
Lighthouse, and PageSpeed Insights that wraps it, are free and excellent at measuring performance, basic accessibility and on-page SEO for one page. PushFix is closer to running Lighthouse across a whole site, then adding the security and functional review it was never designed to do.
Genuinely better at this
- Core Web Vitals and performance scoring in the browser
- Free, instant and built into Chrome DevTools
- On-page accessibility and SEO best-practice checks
- Field data through the CrUX dataset in PageSpeed Insights
What Lighthouse does not attempt
- Crawling more than the one URL you gave it
- Security checks beyond a handful of header and transport rules
- Functional flows, forms, broken links and authorization
- A stored, re-runnable record that proves a fix landed
It is usually not either / or
Most teams keep Lighthouse for the job it was built for and add a review of the running app beside it. The next two rows say which situation is yours, and neither of them is a sales pitch: one of them tells you to stay put.
PushFix and Lighthouse, side by side
6 dimensions, 6 verdicts. Every row is checkable against the other tool's own documentation.
| Dimension | PushFix | Lighthouse |
|---|---|---|
| Covers a whole site, not one URL | Yes | No |
| Security review | 136 checks | Limited |
| Accessibility | Yes | Yes |
| Performance / Core Web Vitals | Yes | Yes |
| Evidence retained and re-checked | Yes | Manual |
| Cost | Free tier | Free |
Yes means supported out of the box. Partial means it can be reached with setup, a plugin, or an extra product. No means the tool was not built for that job, not that it is a bad tool.
Find your situation
Read down the left-hand labels until one of them is about you.
Keep Lighthouse when
You are optimising one page's performance and want the number right now in DevTools. Lighthouse is the right tool for that job.
developer.chrome.com/docs/lighthouse/overview/Reach for PushFix when
You want one pass that measures performance across the site and also tells you what is insecure, broken or missing before launch.
Nothing on this page asks you to take our word for it. Both columns are checkable: Lighthouse's own docs are at developer.chrome.com/docs/lighthouse/overview/, and the fastest way to judge ours is to run one review on a staging URL and read the findings.
The rest of the field
A different tool usually means a different question, not a better one.
The fastest comparison
is your own app.
Point a review at a staging URL and judge the findings, the evidence and the fix prompts for yourself.
