devtools_lighthouse

Run Lighthouse (official CLI) against the developer-mode browser and return category scores, key metrics, failing audits, plus HTML and JSON report artifacts. Developer mode only; Lighthouse opens its own tab in that browser.

The tool names stay the same across browsers. See browser selection and Firefox and Zen exceptions before choosing an operation.

Chromium developer mode only. Lighthouse opens its own tab in the selected developer browser. Pass a developer tabId to choose between running Chromium contexts. Firefox and Zen are unsupported.
