Airbyte Cloud limits

Understanding the following limitations will help you more effectively manage Airbyte Cloud.

Standard plan limitations

These limitations only apply to those using the Standard plan. If you upgrade to Pro or Enterprise Flex, Airbyte removes these limitations.

• Max number of workspaces per user: 1. If you were a Cloud Standard customer before September 24, 2025, Airbyte has grandfathered you into its historical 3-workspace limit.

Cloud limitations for all plans

• Max number of streams that can be returned by a source in a discover call: 1,000

• Max number of streams that can be configured to sync in a single connection: 1,000

• Max number of fields that can be selected to sync in a single connection: 20,000

• Size of a single record: 20MB**

** The effective maximum size of the record may vary based per destination. Some destinations may fail to sync if a record cannot be stored, but Destinations which support typing and deduping will adjust your record so that the sync does not fail, given the database/file constraints. For example, the maximum size of a record in MongoDB is 16MB - records larger than that will need to be modified. At the very least, primary keys and cursors will be maintained. Any modifications to the record will be stored within airbyte_meta.changes for your review within the destination.
