Airbyte is an open-source data integration platform with 350+ connectors. For a marketing agent it is the ingestion layer: it pulls Facebook Ads, Google Ads, Google Analytics, Posthog, HubSpot, and Stripe into a single warehouse so the agent can tie a specific ad to the revenue it drove. Self-hostable or via Airbyte Cloud.

Honest caveat
Airbyte is not a consumer agent tool. It is infrastructure. If you need an agent that reasons across your data, Airbyte is likely part of the pipeline, not the user interface.
