Quick Setup - CLI

Ensure you're using Node.js >=14 and run the following command:

# NPMnpx unlighthouse --site <your-site># or PNPMpnpm dlx unlighthouse --site <your-site>

By default, Unlighthouse will try and find your Google Chrome installation and use that with puppeteer. If you have issues with that you can install puppeteer globally.

npm install -g puppeteer


Unlighthouse will save your reports in outputDir (.unlighthouse by default), it's recommended you .gitignore these files.


As Unlighthouse is in early access, it's recommended you run it in debug mode.

# NPMnpx unlighthouse --site unlighthouse.dev --debug# or PNPMpnpm dlx unlighthouse --site unlighthouse.dev  --debug


Integration instructions, Guides, API and config spec can be found on docs site.
