Estuary Flow: Pricing, Features & Alternatives
Estuary Flow is a real-time alternative to batch ELT: change-data-capture from Postgres, MySQL and MongoDB into warehouses and streams with millisecond latency, backfills and incremental syncs from the same pipeline. Pricing is transparent and usage-shaped — $0.50 per GB plus $100 per connector per month — which tends to beat MAR billing on high-churn tables.
