Meta Pixel Event Studio

Check, build and score your Meta Pixel events in one side panel: pass/fail checks, an event code builder and match quality tips.

Meta Pixel Event Studio is a free Meta Pixel (formerly Facebook Pixel) checker and tester for Chrome that lives in the side panel. Open it on your own website and every pixel event gets a clear pass or fail, a plain reason and a short note on how to fix it. The same panel can write event code for you and estimate how well your events can be matched to the people who triggered them. WHY IT EXISTS Pixel problems are quiet. A purchase without a value, a currency typed in lowercase or an event that fires twice can go unnoticed for weeks while your ad reports drift. This extension watches the events your page sends from the moment it starts loading and turns them into a short verdict you can read in seconds. CHECK: A PASS OR FAIL FOR EVERY EVENT • A verdict card at the top tells you how many events passed, for example 4 of 5. • Each event shows its own parameters in a compact code-style line, so you see exactly what was sent. • Failed events are tinted and show the reason. Open "How to fix" for a plain explanation. • Filter to passed or failed events. Page changes inside single-page shops are grouped so you can follow a whole checkout. • Export what you captured as JSON or CSV to share with a developer or an agency. WHAT IT CHECKS • Purchase events sent without a value or without a currency • Values that are not plain numbers, and currency codes that do not exist • Product events that are missing product IDs or a content type, which catalog ads rely on • Parameter names with a typo, and custom events spelled almost like a standard event • The same event firing twice within two seconds • Event IDs that are missing or reused for a different event • Email addresses or phone numbers placed in event parameters or in the page address • Customer details sent without hashing • A pixel ID in the wrong format, or a page that never sends its page view • A browser cookie that never gets set, and pixel calls that never reach Meta BUILD: CLICK AN ELEMENT, GET THE CODE • Press Pick on page and click a button or a form on your site. The panel works out a stable selector for it. • Choose a standard event or name a custom one, then fill in the suggested parameters. • Read a value straight from the page, such as the price shown next to the button. • Copy a ready snippet for your site, or a tag manager version with step-by-step instructions. • Save setups per site. When a saved event is later seen firing, it gets a badge. • Preview mode highlights the element and logs in the panel what would fire. It never sends anything to Meta. MATCH: AN ESTIMATED MATCH QUALITY SCORE • A score from 0 to 10 based on the customer and browser signals that this browser can see in your events. • A ranked list of what to add, marked high, medium or low impact, each with a plain fix. • It is clearly labeled as an estimate. It is not Meta's official score. FIX COMMON PIXEL PROBLEMS • Meta Pixel not firing when a button is clicked • Purchase event not tracking revenue • Duplicate events after installing a new app or theme • Add to cart event missing product IDs for catalog ads • Low match quality and no idea what to add next PRIVACY FIRST Everything happens in your browser. The extension makes no network requests of its own, has no account and no analytics. Captured events are kept for 3 days on this device and then deleted automatically. You can clear one site or everything at any time. Customer fields are reduced to their names and whether they were hashed, and the values themselves are never stored. ALSO GOOD TO KNOW • Light and dark themes follow your system, with a manual switch in the settings. • The interface is available in 17 languages. • Optional notifications, off by default, tell you when an event fails on a site you are checking or when a saved setup fires. • It works on any website, however the pixel was installed. WHAT IT CANNOT DO The panel sees what your browser sends. It cannot confirm server-side Conversions API (CAPI) delivery, and the event ID checks only help you prepare for deduplication. FAQ Is it free? Yes. Every feature is free, with no account or sign-up. How do I check if my Meta Pixel is working? Open your site, click the extension icon to open the side panel and browse as a visitor would. Each event appears with a pass or fail verdict. How do I test and debug my Facebook Pixel events? Open the Check tab and do the action on your site, such as adding a product to the cart. The event appears with its own parameters, and a failed event shows the reason and how to fix it. How do I add a pixel event to a button without editing my theme? Use the Build tab. Pick the button, choose the event and paste the tag manager version into a Custom HTML tag. Why does my Purchase event fail? The most common causes are a missing value, a missing or invalid currency and missing product IDs. Open "How to fix" on the event to see the exact cause. How can I improve my event match quality? Open the Match tab. It lists what to add in order of impact, with a plain fix for each item. Does the extension send my data anywhere? No. Nothing leaves your browser, and captured events are deleted after 3 days. Is it made by Meta? No. Meta Pixel Event Studio is an independent tool.
