PWMetrics is a CLI tool and Node.js library that gathers progressive web performance metrics (like First Contentful Paint and Largest Contentful Paint) for a URL via Lighthouse. It supports multiple runs with median reporting, JSON output, CI assertions against expectations, and uploading traces to Google Drive or Sheets.

Use cases

  • measure page load performance metrics for a url
  • run lighthouse performance audits from the command line
  • assert performance budgets in CI pipelines
  • export web vitals metrics as
  • track first contentful paint and largest contentful paint over time

When to choose

  • you need a quick one-off CLI to collect Lighthouse timing metrics
  • you want a Node library to programmatically gather performance metrics

When to avoid

  • starting a new project - it is deprecated in favor of Lighthouse CI
  • you need ongoing page speed monitoring or maintained tooling
  • you need GitHub Actions integration for Lighthouse
