Frequently asked questions

Is Estuary better for real-time streaming?

Estuary excels at continuous streaming pipelines. NoSQLSync focuses on database migration — both one-time and ongoing CDC. For pure migration use cases, NoSQLSync is simpler and more purpose-built.

Which is easier to set up?

NoSQLSync is designed to go from signup to migration in minutes. Estuary requires understanding flows, collections, and materializations before data starts moving.
