SignalBridge
5.0 out of 5 stars
(1 Rating)
SignalBridge is a server-side tracking platform that sends conversion events to Meta, Google, TikTok, and other ad platforms - bypassing ad blockers, iOS privacy restrictions, and cookie limitations that cause browser pixels to miss conversions.
When a customer completes a purchase or fills out a form, SignalBridge captures the event server-side through a custom first-party subdomain and sends it directly to Meta Conversions API, Google Enhanced Conversions, and TikTok Events API with hashed customer data for accurate attribution.
Key features include server-side tracking across 3 ad platforms, bot filtering, funnel analytics with drop-off visualization, ad spend sync for true CPA and ROAS, Event Match Quality monitoring, smart tracking links with geo-targeting and A/B testing, and real-time event debugging.
Works with Shopify, WooCommerce, Webflow, and any custom site via a single script. Setup takes 5m - no GTM or developer required. 14-day free trial, no credit card needed.

StillFiring
Broken ad tracking is the most expensive kind of bug because it produces no error. Orders keep arriving, checkout works, the storefront looks fine — and the only symptom is a number in Google Ads or Meta going quietly wrong, usually noticed weeks later once the budget is spent.
StillFiring reads your public Shopify storefront the way a shopper's browser does and tells you what is actually running on it: every tracking pixel, named, plus what customer data each one is declared to collect and which ones look broken, duplicated, or running unsandboxed. The check is free, needs no account and no install, and you can run it as often as you like.
Paid monitoring re-checks your store every hour and emails you the day something changes — never otherwise. Silence means everything is still running. $29/month for one store, 14 days free, billed through Shopify so it lands on your normal store invoice.

CheckoutAlarm
CheckoutAlarm is a hosted monitoring service for founders and independent makers running applications that accept payments through Stripe. It periodically loads a selected website page and checks its response status, speed, and whether an expected page title or phrase is present. For Stripe, it monitors undelivered webhook events and disabled endpoints, and can alert when sales activity stalls. Before monitoring begins, site ownership is verified using a DNS record, a meta tag, or a verification file. CheckoutAlarm sends email alerts after two consecutive page-check failures and a recovery notice when the check succeeds again; Stripe alerts are also sent by email. The Free plan checks one site daily. Pro checks up to three sites hourly for $19 per month. CheckoutAlarm helps identify website availability and Stripe payment-delivery problems through scheduled monitoring.

Taglert
Taglert monitors the ad-tracking health of your client accounts and alerts you when something breaks. Ad pixels and conversion tracking break quietly after site updates and plugin changes, and the dashboard keeps showing conversions while budget spends on bad data, so agencies often find out weeks later.
Taglert continuously checks each client's Meta pixel activity, Conversions API Event Match Quality (EMQ), duplicate events, and Google Ads conversion tracking status, and alerts you by email and Slack the moment something breaks.
Built for managing many accounts: connect each ad account once with a secure login (no code to install) and monitor them all from one dashboard. Broken tracking can waste around 23% of an ad budget. 7-day free trial, no credit card required.
