DriftGate

DriftGate is a web app (with optional CLI agent) that monitors ETL pipelines for “silent failures”: data that loads successfully but is wrong due to upstream changes, partial extracts, or shifting distributions. Instead of focusing on orchestration, it plugs into your warehouse/lake (Snowflake/BigQuery/Databricks) and computes lightweight, configurable checks: freshness, volume, null-rate, uniqueness, referential integrity, and distribution drift on key columns. It auto-suggests baselines from historical runs and flags anomalies with clear, actionable diffs (what changed, where, and likely cause). Alerts route to Slack/PagerDuty with links to a runbook and the exact query to reproduce. This is not a magic “AI fixes everything” tool; it’s pragmatic guardrails that reduce time wasted chasing phantom bugs and broken dashboards. Pricing is per monitored table/job, aiming at teams that already spend real money on data reliability incidents.
