A free alternative to Lighthouse
Google's open-source auditing engine, built into Chrome DevTools and runnable from the command line or CI. It's the engine behind PageSpeed Insights.
What Lighthouse does well
- Free, open source, and already sitting in your browser's DevTools.
- Runs locally against staging or localhost — no public URL required.
- Scriptable in CI, so you can fail a build on a performance regression.
- Covers performance, accessibility, best practices, and SEO basics in one run.
Where it stops
- Built for developers — running it in CI and interpreting the output assumes a technical audience.
- Its SEO and accessibility checks are deliberately basic, and trust or conversion aren't in scope at all.
- Nothing is stored or tracked over time unless you build that yourself.
What MyWebsiteScore adds
- A hosted report you can send to a client or colleague, with nothing to install.
- Conversion, clarity, and trust scored alongside the technical checks.
- History and weekly monitoring without building a pipeline for it.
Which should you use?
If you're a developer who wants audits against localhost or wired into CI, use Lighthouse. It's free, scriptable, and the right tool for that job — we'd tell you to use it.
