WebPageTest GitHub Action


WebPageTest's GitHub Action lets you automatically run tests against WebPageTest on code changes. You can set and enforce performance budgets, and have performance data automatically added to your pull requets to move the performance conversation directly into your existing development workflow.


  • Automatically run WebPageTest against code changes
  • Set and enforce budgets for any metric WebPageTest can surface (spoiler alert: there are a lot)
  • Complete control over WebPageTest test settings (authentication, custom metrics, scripting, etc)
  • Automatically create comments on new pull requests with key metrics, waterfall and more.

Using the Action

  1. Get a WebPageTest API Key and store it as a secret in your repository's settings.

WPT_API_KEY Secret in repo settings

    runs-on: ubuntu-latest
    name: WebPageTest Action
      - name: Checkout
