As answered by people managing Codility and Taglert.
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.
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.
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.
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.
Taglert's answer:
Next.js, Supabase, and Cloudflare, with the Meta Marketing API and Google Ads API for the tracking-health data.
