CostDrift

CostDrift is a web app (with optional Slack/Teams integration) that monitors Snowflake/BigQuery/Redshift usage and flags cost anomalies tied to specific queries, dashboards, users, and pipelines. It ingests billing exports and query history, builds a baseline per workload, and alerts when spend or credits deviate beyond expected ranges (e.g., a dbt model suddenly scanning 10x data). The product focuses on fast root-cause, not pretty charts: it shows the exact query patterns, recent code changes, and the downstream owners to contact. It also recommends concrete fixes like clustering/partition changes, warehouse sizing schedules, materialization swaps, and caching opportunities. Be realistic: incumbents exist, so the wedge is “actionable, owner-mapped alerts” that engineers will actually trust, plus a lightweight setup that doesn’t require a full FinOps program.
