Speed in China | Test Website Speed from Mainland China | GFW Optimization & Google Fonts
Speed Test Results
How fast is your website for visitors in mainland China? Speed in China runs real HTTP speed tests from Chinese servers, scans for Great Firewall blocked resources, and localizes Google Fonts — all from your WordPress Dashboard.
⚡ FREE MAINLAND CHINA SPEED TESTS
Run one free speed test every 30 days using multiple servers in mainland China with the click of a button.
🌏 MULTIPLE SERVER LOCATIONS
Speed tests run from servers in different Chinese provinces — including Beijing, Shenzhen, Guangzhou, Shanghai, and Qingdao — to give you a comprehensive picture of your site’s performance in China.
🔍 CHINA RESOURCE ANALYSIS
Automatically scan your site for resources blocked by the Great Firewall (GFW). Detects Google services, social media embeds, blocked CDNs, and other China-incompatible resources.
🔤 LOCALIZE GOOGLE FONTS
Google Fonts (fonts.googleapis.com) are blocked in China. Enable one-click localization to download and serve Google Fonts locally so Chinese visitors see your site with the correct fonts.
📊 OPTIMIZATION INSIGHTS
After each speed test, get actionable suggestions to improve your site’s performance in China based on DNS, TCP, TLS, TTFB, and total load time metrics.

Because of API limitations and usage, you can upgrade to one of our paid plans to run speed tests more frequently.

External Services
This plugin connects to the following external services. None are contacted until you explicitly opt in (click “Allow & Continue” on the connect screen), with the single exception of the Google Fonts download flow, which only runs when you separately enable the “Localize Google Fonts” toggle on the Optimizations tab.
Speed in China API (api.speedinchinaplugin.com)
This plugin sends your public site URL to our backend API at https://api.speedinchinaplugin.com/wp-json/speed-in-china-api/v1/speed-test each time you click “Start Speed Test”, which proxies the request to the Globalping network (api.globalping.io) to run real HTTP timings from probes in mainland China. We also perform a once-per-hour reachability health check by GETting https://api.speedinchinaplugin.com/wp-json/; no site data is sent. Speed test results are stored in your WordPress options table only; we do not retain them server-side.
Globalping (api.globalping.io)
Our Speed in China API runs your speed test through the Globalping network (operated by jsDelivr). Globalping probes in mainland China receive only your public site URL — no user-identifying data — and return raw timing/HTTP-status data to our API, which forwards it back to your WordPress site.
Freemius (api.freemius.com, freemius.com)
This plugin uses the Freemius SDK for license activation and opt-in management. When you click “Allow & Continue” on the opt-in screen, Freemius receives your admin email, site URL, WordPress and PHP versions, and the plugin version, in order to issue a license token and (for premium customers) deliver license updates. Nothing is sent before you opt in; clicking “Skip” or “Maybe Later” keeps the plugin in anonymous mode and no Freemius requests are made.
Google Fonts (fonts.googleapis.com, fonts.gstatic.com)
When you enable Google Fonts localization on the Optimizations tab, this plugin connects to Google’s Fonts API (fonts.googleapis.com and fonts.gstatic.com) to download font stylesheets and font files, which are then stored and served locally from your server. The font family names already present in your site’s HTML are sent to Google as part of the download URL. No personal visitor data is transmitted to Google by this plugin. The toggle is off by default; no Google Fonts request is ever made until you enable it.
