MetricPatch

MetricPatch is a no-code web app that sits between your data sources and your reporting dashboards to detect, explain, and prevent KPI breakage. Instead of building yet another dashboard, it monitors the assumptions behind metrics: schema changes, missing joins, shifted timezones, duplicated rows, and silent filter drift. Users connect common sources (Stripe, HubSpot, GA4, Postgres, BigQuery) and define KPIs with a simple builder. MetricPatch continuously validates metric outputs against historical baselines and rule checks, then alerts you with a plain-language “what changed” report and a one-click patch (e.g., update field mapping, adjust date logic, exclude a new test campaign). It also generates an audit trail so stakeholders can trust numbers again. This is a combination traditional + AI app: traditional rules and lineage plus AI-generated explanations and suggested fixes.
