The lint rules
A second pair of eyes for every event.
Pixel Lint turns a noisy implementation into a clear pass, warning, or fix.
RULE_02
Validate the schema
Check event parameters, value types, currencies, and content IDs.
RULE_03
Catch duplicates
Spot repeated signals before they distort attribution and reporting.
RULE_04
Surface violations
Get clear, plain-language warnings instead of digging through raw requests.
RULE_05
Inspect every frame
Audit embedded checkout and iframe activity without missing the edge cases.
RULE_06
Ship with confidence
Turn a live browser session into a fast quality check before launch.
For the people on the hook
Better data starts with better checks.
Media buyers
Verify the conversion signal before you scale spend.
Agency teams
Turn pixel audits into a clean, repeatable handoff.
Commerce teams
Make sure every checkout step sends the data your store needs.
Developers
Trace the payload, resolve the edge case, and ship confidently.
Put your pixel under the microscope
