Frequently Asked Questions

  • What is the difference between this and running Lighthouse in Chrome?
    Running it in Chrome is manual and depends on your local computer's speed and internet. Our API runs it on cloud servers, allowing you to automate thousands of checks with comparable environments.

  • Can I choose between Mobile and Desktop?
    Yes. You can specify the device parameter to switch between Mobile and Desktop (default) emulation to see how scores differ.

  • How can a pagespeed API help improve website performance?
    A pagespeed api provides programmatic access to detailed metrics like Core Web Vitals and load times. By functioning as a comprehensive website audit api, it allows developers to pinpoint performance bottlenecks such as unoptimized images or render-blocking scripts and implement data-driven fixes before they impact the end user.

  • Can Lighthouse API be used for website automation tasks?
    Yes, our Lighthouse API is highly effective for website automation. You can integrate it directly into your CI/CD pipelines to automatically trigger audits on every code commit. This ensures performance, accessibility, and SEO standards are strictly enforced alongside your regular API Testing and deployment.

  • What are the benefits of using a performance testing API for websites?
    Using a performance testing api delivers consistent data at scale without manual intervention. It enables development and QA teams to run repeatable audits across hundreds of URLs simultaneously, catching regressions early and ensuring your application consistently meets industry benchmarks.

  • How does a website monitoring API help track performance issues?
    Continuous website monitoring allows teams to track historical data and spot performance regressions over time. By scheduling regular Lighthouse API calls, you can establish baseline metrics, track trends, and trigger alerts the moment a recent code change degrades your site's speed.

  • Is Lighthouse API suitable for large-scale website monitoring?
    Yes, Geekflare infrastructure is built for scale. Whether you are tracking a handful of landing pages or running daily website monitoring across thousands of URLs, our API supports concurrent processing to deliver Lighthouse insights reliably.

  • How much does a Lighthouse audit cost?
    Because Lighthouse audits are resource-intensive tasks, they consume 10 credits per request.

  • Why are my scores different from PageSpeed Insights?
    Scores can vary based on network conditions and server load at the exact moment of testing.
