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, plugin changes, and consent-tool changes. The dashboard keeps showing conversions while the budget spends on bad data, so...

As answered by people managing Taglert and AnalyticsProof.
Taglert's answer
Taglert is built specifically for agencies and media buyers, not data teams. It monitors the ad-tracking signals that actually cost money when they break (Meta pixel activity, Conversions API Event Match Quality, duplicate events, and Google Ads conversion tracking) across every client account from one dashboard, and alerts you the moment something breaks. It needs no code: you connect each ad account with a secure login.
AnalyticsProof's answer:
User journey tests are recorded once in a browser that runs on our servers, then replayed every day. Each step shows what the page pushed to the dataLayer next to what was sent to GA4 (and other tools), plus a cookie-banner check of what tools send before consent and after rejection. An MCP server lets AI assistants read results and set up checks.
Taglert's answer
Most alternatives are analytics data-governance platforms built for product teams, or they require a data-layer integration. Taglert is simpler and ad-focused. It watches Meta and Google Ads tracking across many client accounts, sends instant email and Slack alerts, needs no code, and starts with a free trial. If your job is catching a broken pixel before the client does, Taglert is purpose-built for exactly that.
AnalyticsProof's answer:
It checks the journeys that make money, such as cart and checkout, step by step, and says exactly which event or parameter stopped arriving after a release. Nothing is installed on the site. The same check runs on Android and smart-TV apps, which most tag-audit tools don't cover. Pricing starts with a free plan instead of an enterprise contract.
Taglert's answer
Marketing agencies and freelance media buyers who run paid ads for multiple clients. They manage several Meta and Google Ads accounts and need to know the moment a pixel or conversion tag breaks, because broken tracking wastes budget and can cost them the client.
AnalyticsProof's answer:
Analytics leads, Head of Digital and e-commerce managers at companies that release often, and analytics/PPC agencies that look after tracking on many client websites.
Taglert's answer
Taglert was built after seeing how often a client's pixel or conversion tracking breaks silently. The ads keep spending, the dashboard still shows conversions, and nobody notices until results drop and the client asks why. Taglert closes that gap by monitoring every account continuously and alerting you first.
AnalyticsProof's answer:
Built by Václav Ráš, a web analytics consultant who kept finding the same problem with clients: a release quietly breaks tracking and nobody notices for weeks. AnalyticsProof automates the check he used to do by hand in DevTools after every release.
Taglert's answer
Next.js, Supabase, and Cloudflare, with the Meta Marketing API and Google Ads API for the tracking-health data.
