In-dashboard performance auditing of TTFB, request count, PSI core vitals, autoloaded options, and more.
== Description ==

Speed Analyzer gives you an in-dashboard speed audit of your website for:

1. **Server TTFB**  
2. **Requests & Page Size**  
3. **Autoloaded Options**  
4. **Persistent Object Cache**  
5. **PageSpeed Insights (LCP & FCP)**
6. **Summary & Recommendations**
7. **Conclusion & Pro-service offer**
8. **A complete PDF report with color coding, explanations and links to the guides**

It uses Cloudflare Workers and Google PSI API under the hood (your data is NOT stored on any external site). A 10-tests/day fair-use limit is enforced on the current version.  
PDF reporting (with color coding, explanations and links to the guides) is available from version 1.10.

== Serviceware Model ==

Speed Analyzer is an open-source WordPress plugin that acts as a thin client for our hosted analysis service.  
All quota- and tier-enforcement happens on our CF Worker/Google PSI proxy.  


== Installation ==

1. Upload the `speed-analyzer` folder to `/wp-content/plugins/`.  
2. Activate the plugin through the “Plugins” menu in WordPress.  
3. Go to **Tools → Speed Analyzer** to run your first audit.  
4. After the tests are complete, a Generate PDF report button will be available.
5. (Optional) Upgrade at **Speed Analyzer → License** for higher quotas.

All PHP and JavaScript code is included in this plugin. No features are disabled locally—every quota, gating, and license-check is performed on our remote service.

== Included Files ==
- **assets/js/html2pdf.bundle.min.js**  
  Bundled copy of html2pdf.js (v0.10.3) for offline PDF generation.
  Source: https://github.com/eKoopmans/html2pdf.js

== External Services ==
Speed Analyzer doesn’t run any tests locally — every audit is performed by our managed service at https://globalwpspeed.dalibord79.workers.dev.

1. **Google PageSpeed Insights API**  
    • Modules 2 and 5 of the plugin ultimately fetch (via our proxy worker) real‐time LCP/FCP/diagnostic data from Google’s PSI service.
    • Instead of hitting www.googleapis.com directly, the plugin sends your test URL + strategy to Cloudflare Worker, which then forwards the request to Google PSI on your behalf.
    – Terms of Service: https://developers.google.com/terms
   

2. **Cloudflare Workers HTTP Probe**  
    – Module 1 (Server TTFB) calls https://globalwpspeed.dalibord79.workers.dev/ to measure Time-to-First-Byte from a global edge.
    – Modules 2 and 5 (Page asset summary and Diagnostics) now send psi_url to https://globalwpspeed.dalibord79.workers.dev/psi. That Worker then forwards the same parameters to Google PSI and returns the JSON back to the plugin.
    • What data is sent and when:
    – For TTFB: just the raw URL—no other user data.
    – For PSI: the URL you enter plus “mobile” or “desktop” strategy.
    
    No personal information is collected or stored.
    • Provider & policies:
    Hosted by WPservice (Dalibor Druzinec).
    – Privacy Policy: https://wpservice.pro/privacy-policy
    – No PII is collected; only your tested URL and strategy are transmitted.

3. **Usage Tiers**
   These are the **service-enforced** daily limits provided by our hosted service:

== Frequently Asked Questions ==

= Why is there a daily limit? =  
Because we leverage external APIs with shared quotas. You get 10 free tests/day; more or unlimited tests require a premium license.  

= Will you collect any of my data? =  
No—everything runs on your server, and no results are stored on our site. 

= What happens when I hit my daily test limit?  =
The server will return a “quota exceeded” error. You can either wait until midnight UTC or upgrade your tier to continue testing immediately.
