Frequently asked questions

Is Airbyte open source?

Yes, Airbyte is open source with a self-hosted option. NoSQLSync is fully managed SaaS, which means zero operational overhead for you.

Does Airbyte support CDC for MongoDB?

Airbyte recently added CDC support, but it's still maturing. NoSQLSync was built from the ground up for CDC with sub-second latency.

Which is better for a one-time migration?

For a one-time MongoDB/DynamoDB/Firestore to SQL migration, NoSQLSync is purpose-built and significantly faster to set up. Airbyte is better if you need ongoing ELT pipelines for many different sources.
