SignalLint – Meta Pixel & Conversion Debugger

Description

Debug Meta Pixel events in real time. Catch duplicate conversions, invalid Purchase data, and tracking issues. **SignalLint is a privacy-first Meta Pixel debugger that helps you see what your website is actually sending — in real time.** Instead of guessing whether your Meta Pixel is working, open SignalLint and inspect the events fired on the current website directly from a clean Chrome side panel. SignalLint is built for marketers, developers, store owners, and anyone who needs a clearer view of Meta Pixel tracking without digging through browser developer tools. ### See Meta Pixel events as they happen SignalLint captures Meta Pixel events during your debugging session and displays them in a live event stream. It can recognize standard and custom events, including events such as: * PageView * ViewContent * Search * AddToCart * AddToWishlist * InitiateCheckout * AddPaymentInfo * Purchase * Lead * CompleteRegistration * Contact * Subscribe * Custom events Click any event to inspect its available parameters and tracking details. ### Inspect event data clearly Open an event to review the data associated with it, including available information such as: * Pixel ID * Event name * Event type * Timestamp * Value * Currency * Content IDs * Content type * Custom parameters * Page URL Raw event data can also be viewed and copied as JSON when you need a closer look. ### Automatically detect Meta Pixel IDs SignalLint detects Meta Pixel IDs found during the active debugging session and shows them in the Pixels tab. This makes it easier to see which Meta Pixel is present on the page and associate observed events with the detected Pixel. Multiple Pixel IDs can also be displayed when more than one is detected. ### Catch common tracking issues SignalLint includes local validation designed to highlight useful tracking problems while you browse. It can identify issues such as: * Duplicate conversion events * Invalid Purchase values * Missing Purchase currency * Missing Purchase value * Suspicious or incomplete event data Issues are shown separately so you can review potential tracking problems without searching through every captured event. ### Match interactions with Meta events SignalLint can observe relevant user interactions during an active debugging session and help show whether a Meta event was detected around that interaction. This can make it easier to understand whether a tracked action, such as a contact interaction, resulted in a Meta event. ### Search and filter captured events Use the built-in search and filters to quickly review: * All events * Standard events * Custom events * Events with detected issues You can also pause the event view or clear the current debugging session when needed. ### Privacy-first by design SignalLint runs locally in your browser. **No account is required.** SignalLint does not include advertising, affiliate injection, or analytics tracking in the extension. Debugging session data is processed locally and is not uploaded to a SignalLint server. The extension uses temporary access to the website you explicitly choose to inspect rather than requesting permanent access to every website you visit. ### Simple workflow 1. Open the website you want to inspect. 2. Click the SignalLint toolbar icon. 3. SignalLint opens in the Chrome side panel. 4. Browse the website normally. 5. Watch Meta Pixel events appear in real time. 6. Inspect events, Pixel IDs, parameters, and detected issues. No complicated setup is required. --- **SignalLint – Meta Pixel & Conversion Debugger** See what your Meta Pixel is firing. Inspect the data. Catch tracking problems before they become harder to find.
