About the Meta Pixel Checker
Decode any Meta Pixel
Every page with a Meta (Facebook) Pixel downloads that pixel's configuration from Meta. It contains the codeless events set up in Events Manager, the customer data sent for advanced matching, server-side settings and restrictions. The Meta Pixel checker reads it and scores the setup.
Advanced matching
Which customer fields (email, phone, name) the pixel sends to improve matching.
Server-side
Conversions API Gateway and first-party setups found in the configuration.
Setup score
A 0–100 score with the biggest improvements to make next.

Questions
How do I check if a website has a Facebook Pixel?
Enter the website in the Meta Pixel checker. TagSpy finds any pixel on the page or inside its Google Tag Manager container and opens its configuration.
Is this like the Meta Pixel Helper extension?
It answers similar questions without installing anything, and goes further: it reads the pixel's configuration directly, including codeless rules and advanced matching fields the extension doesn't list.
Can I see another site's Conversions API setup?
When the pixel's configuration shows a Conversions API Gateway or a first-party endpoint, the checker reports it. Server-to-server events sent by a backend are not visible to anyone outside.
Do I need access to Events Manager?
No. The configuration is public: Meta serves it to every visitor's browser. Nothing is installed, no login is needed, and nothing you check is stored.
