Chrome Dependency

The local Lighthouse auditor requires an installed Chrome browser. Chrome Launcher discovers the browser used by each audit worker.

Select an installed browser

CHROME_PATH=/usr/bin/google-chrome pnpm exec unlighthouse --site https://example.com

Set CHROME_PATH to the executable available on your machine or container. Use CHROME_FLAGS for process arguments. See Chrome Options.

Previous download settings

Legacy chrome.useSystem and download-fallback options do not configure the v1 local auditor. Install the browser before running scans. puppeteerOptions.executablePath has no effect on the v1 local auditor.
