LagReveal helps you separate the wait for WordPress to send the page from the time the browser spends downloading images, scripts and styles. Open a page as an administrator to investigate the WordPress side, then capture a logged-out visit to see how the public page loads. **Start with one slow page** 1. Open Tools > LagReveal, enter a page URL on your site and click **Measure current performance**. 2. In **Top Fixes**, open a finding to see the timing behind it. If the HTML document is slow, open **HTML response** to separate connection time, the wait for the first byte and the HTML download. The response wait alone does not tell you which plugin caused it. 3. Use **Database requests** to find the slowest queries and **Repeated database requests** to find small queries that add up. Where available, LagReveal shows the calling plugin or theme, file and line. Administrators with file-editing permission can open supported files in the WordPress editor. 4. Open **Loading waterfall** to see when each file started and how long it took. Sort by duration to find long requests. For supported elements, the inspector can also show the matching HTML or Elementor widget so you can locate it on the page. **How to test as a visitor** A logged-in administrator may bypass your page cache. To see what a shopper or first- time reader receives, collect a second report from a private browser window: 1. Keep your administrator capture open. Select **Test as a visitor**, then **Copy guest collector bookmark**. 2. In your browser’s bookmark manager, create a bookmark named **LagReveal Visitor Test**. Paste the copied code into its **URL** field and save it. You create this bookmark once; it is not a tab in Chrome DevTools. 3. Open a fresh Incognito or Private window in the same browser. Visit the clean page URL shown in LagReveal without signing in. Wait for it to finish loading, then scroll or interact with any content you want included. 4. While still on that page, click the bookmark. It downloads **lagreveal-guest.json**. Opening the visitor tab in the administrator panel does not start a download. 5. Return to the administrator window. Under **Test as a visitor > Import guest capture**, choose the downloaded file. The **Loading waterfall** opens with the visitor’s timings. Click **Capture again** to return to the administrator measurements. The visitor report shows browser measurements, including response wait and resource timings. It cannot see PHP or database queries. Use the administrator capture to investigate those. Guest imports must come from the same site origin and stay in the browser. **Try a change before applying it to visitors** Use **Manage scripts & styles** to test removing an optional script or stylesheet on a specific page. On WooCommerce stores you can also test the classic mini-cart fragment settings. Run **Test optimizations**, repeat the same interactions and compare a fresh capture. For a store, check adding and removing a product and refreshing the mini-cart before enabling visitor rules. Fresh installations leave visitor rules off. **Report privacy** Administrator reports are private to the capturing account and expire after 24 hours. LagReveal uses no external telemetry service. Exported files can contain URL paths, query structure and plugin or theme filenames; review them before sharing. ## Screenshots [⌊Top Fixes ranks the slowest parts of a page and shows where to investigate first.⌉⌊ Top Fixes ranks the slowest parts of a page and shows where to investigate first .⌉[ Top Fixes ranks the slowest parts of a page and shows where to investigate first.

[[ [[ ## Installation 1. Upload the ZIP through Plugins > Add New Plugin > Upload Plugin. 2. Activate LagReveal and open Tools > LagReveal. 3. Capture a frontend page and review Top Fixes. 4. Test one optimization at a time before applying rules to visitors. Upgrading from the previous branded package: deactivate the previous plugin first. LagReveal uses a new folder and retains compatible settings. Existing visitor rules are preserved; review them before testing. See README.md for full instructions. ## FAQ ### Does this automatically optimize every page? No. It diagnoses performance and provides optional controls you can test first. ### Does it require WooCommerce or Elementor? No. Their diagnostics and controls apply when those plugins are present. ### Can it identify every cause of slow HTML? No. Browser waiting time can include network and server work. SQL capture starts at plugins_loaded and does not cover the whole server request or external systems. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “LagReveal” is open source software.
