Monitors BigQuery pipelines, detects data anomalies, and helps teams reduce and track cloud compute costs.
Masthead Data is a data observability and FinOps platform built specifically for Google BigQuery. It is aimed at data engineering and analytics teams that need to keep pipelines reliable while controlling cloud compute spend. The platform monitors pipelines, automatically detects data and pipeline anomalies, and provides visual lineage so teams can trace issues to their root cause. Its FinOps features help teams optimize BigQuery compute costs, and it also supports defining data products to see their costs, users, and value. The product is sold through paid plans with a demo request, and the site does not list a free tier.
