We're live on Product Hunt — support us

Your tracking breaks quietly.

A trigger changes, a consent flag flips, a developer ships a new checkout — and nothing tells you. Tagfire watches every tag across every account you manage, and emails you a screenshot the moment one stops firing.

Catch broken tracking before your client does.

The Tag Debugger is the heart of Tagfire. Everything else in the suite exists to support the loop it runs.

  1. 01

    Watch it live

    Every GA4 and Measurement Protocol hit decoded as you browse — in your browser, or in a headless session Tagfire drives for you.

  2. 02

    Record the journey once

    Click through the flow that matters. Tagfire keeps the steps, and you declare what has to fire for it to count as passing.

  3. 03

    Put it on a schedule

    Bundle recordings into a monitor. It replays them daily or weekly without anyone remembering to check.

  4. 04

    Get told, with proof

    A failed assertion or a page that visually drifted past your threshold sends one digest email, screenshots attached.

This is the email nobody wants to get and everybody needs: the checkout stopped sending purchase some time in the last 24 hours, and the page moved 4.71% while it happened.

02The suite

Thirteen tools that replace a folder of spreadsheets.

03The name

Tagfire, literally.

Tagnoun

The trackers running your business.

GA4, GTM, Meta, LinkedIn, TikTok — every pixel and script bolted onto a site to measure something that matters. The pieces every CMO assumes just work.

Fireverb

The moment everything is decided.

A tag fires when the trigger says now. Get that wrong and you ship duplicate conversions, missing revenue, broken attribution. Get it right and the whole stack tells the truth.

Tagfire makes sure every tag fires exactly when, where, and how it should — across every account you touch.
