Speed Analyzer is a WordPress speed test and performance audit plugin that runs from wp-admin. It combines Google PageSpeed Insights data with WordPress-specific checks that browser-based testing tools cannot access, including autoloaded options, database size, active plugins, persistent object cache, and server information.
Use one dashboard to identify whether a performance bottleneck comes from the server, frontend assets, Core Web Vitals, or the WordPress database. Save results, compare before-and-after tests, schedule recurring checks, receive reports by email, and generate color-coded PDF reports.
WordPress.org reviewers highlight having PageSpeed data inside WP Admin and getting clearer direction about what to optimize.

Speed Analyzer is a diagnostic and reporting tool. It identifies performance problems and recommends next steps, but it does not automatically apply caching, CSS, JavaScript, image, or database optimizations.

External Services
Speed Analyzer performs WordPress-specific database and server checks locally. When you start a speed test, or when a scheduled test runs, selected modules connect to a managed WPservice analysis service and Google PageSpeed Insights. If you enter a license key, the plugin also contacts the WPservice license service to activate the license and to check its status and daily allowance.
WPservice hosted analysis service
Endpoints (the plugin alternates between the two):
https://globalwpspeed.dalibord79.workers.dev/
https://globalwpspeed1.dalibord79.workers.dev/
The hosted service is used for:
Measuring TTFB from a Cloudflare edge location
Fetching page asset and PageSpeed data
Proxying PageSpeed requests to Google
For TTFB tests, the tested URL is sent to the service. For PageSpeed tests, the tested URL and selected mobile or desktop strategy are sent. The service returns the test data to the plugin. No personal information is intentionally collected, and test results are not stored on the WPservice website.
Service terms: https://wpservice.pro/terms-and-conditions/
Google PageSpeed Insights
The hosted WPservice endpoint forwards the tested URL and mobile or desktop strategy to the Google PageSpeed Insights API. Google returns PageSpeed, Lighthouse, diagnostics, and available Core Web Vitals field data.
Google API Terms of Service: https://developers.google.com/terms
Activating and deactivating a license key on your site
Checking the license’s tier, status, and expiry date
Checking the daily speed-test and PDF-report allowance for the license
When you activate a license key, the key and your site URL are sent to the service. When you deactivate it, the key and the activation token the service issued at activation are sent. Whenever a speed test (including a scheduled test) or PDF report is run, and when the Speed Analyzer admin screen, including its License panel, is opened, the license key, the operation being checked (speed test or PDF report), today’s usage count for that operation, and your site URL are sent. The service returns the license’s status, tier, expiry date, remaining daily allowance, and site-usage details to the plugin. Speed Analyzer only contacts this service once you enter a license key; sites without a license key do not contact it.

Frequently asked questions.
Does Speed Analyzer make my WordPress website faster?
Not automatically. Speed Analyzer measures performance, identifies likely bottlenecks, and explains what needs attention. You can use its results to guide manual optimization or confirm the effect of changes made by another plugin or developer.
How is it different from running PageSpeed Insights directly?
Speed Analyzer brings PageSpeed and Core Web Vitals data into wp-admin and combines it with WordPress-only information such as autoloaded options, database size, persistent object cache, active plugins, and server details. It also adds saved comparisons, scheduled tests, alerts, email results, and PDF reporting.
Is the free version enough to test my website?
Yes for ordinary use. The free tier includes up to 10 tests and one PDF report per day. Higher-volume users and agencies can choose a paid tier.
Why is there a daily limit?
The remote tests use hosted infrastructure and external API quotas. Limits reset at midnight UTC. When the limit is reached, wait for the reset or upgrade to a tier with a higher allowance.
What is sent to external services?
The tested public URL is sent for TTFB checks. PageSpeed tests also send the selected mobile or desktop strategy. WordPress-specific information such as your autoloaded-options list, active-plugins list, and database details is processed locally and is not needed by the remote PageSpeed or TTFB tests. If you enter a license key, the key, your site URL, the operation being checked and today’s usage count are sent to the WPservice license service; deactivating a license sends the key and its activation token. Sites without a license key never contact the license service.
Where are my saved test results stored?
Saved comparison and scheduled-test data is stored on your WordPress website. WPservice does not store your completed report data on its website.
Why can two PageSpeed tests return different scores?
PageSpeed results can vary because server response time, network conditions, cache state, third-party scripts, and the tested environment change between runs. Compare several tests rather than treating one score as permanent.
Why does Speed Analyzer show TBT and INP?
Total Blocking Time is a Lighthouse lab metric used in PageSpeed performance tests. Interaction to Next Paint is a Core Web Vital based on real-user field data. They measure related but different aspects of responsiveness and are not interchangeable.
