Hit Log Filter
The hit filter is a search box. It keeps only the hits whose event name, account id, or any decoded parameter value contains what you type. The match ignores case and updates as you type, so you can focus on one event fast.
Why it matters
On a busy page, a hundred tracking requests fire in seconds. You want to find one thing: a specific event, a particular product id, a conversion with a certain value. Scrolling through a massive list wastes time. The hit filter cuts through the noise instantly.
How it works
Type in the search box at the top of the panel. Scalpel Tags keeps only the rows that match what you typed. The match is case-insensitive and covers three things: the event name, the account id, and any decoded parameter value in the request. As you type, the results update live.
If you search for purchase, you see all Purchase events. If you search for G-ABC123, you see only GA4 hits from that measurement id. If you search for a product price like 29.99, you'll find the hit that sent that value.
What does not matter
The filter doesn't search raw request URLs or parameter names. It only looks at decoded, human-readable fields. So searching for tid (the parameter name) won't find GA4 hits. Search for the measurement id itself instead.
The search also doesn't match against the timestamp or status code. Use the provider filter above the search box to cut vendors instead.
Code example
The hit filter is not something you code. But here's what it looks for on a Meta Pixel Purchase event:
Request URL: facebook.com/tr?data=%7B%22...%7D
Decoded fields:
- Event name:
Purchase - Pixel id:
1234567890 - Value:
99.99 - Currency:
GBP
Type Purchase and the row shows. Type 1234567890 and it shows. Type 99.99 and it shows. Type eur and it doesn't.
How Scalpel Tags shows it
The search box lives in the toolbar at the top of both the popup and the DevTools panel. Start typing and the table updates instantly. The filter stacks: combine it with the provider filter (the vendor chips) and mutes to focus on exactly what you're debugging.
Clear the box or press Escape to show all hits again.
