What the integration does

  • The integration will create a Playwright check including web vitals against the target website automatically.
  • This check runs in a real Chrome browser, screens the browser's console log, and fails when errors occur.
  • If checks fails, it will stop your production deployment.
  • You can add customized checks from the Checkly account and link them to your Vercel project.
  • Next to browser checks, Checkly supports API checks (deeply customizable HTTP requests).
