 * **Airbyte supports more than 60 connectors after only 8 months since its inception**, 20% of which were built by the community. Our ambition is to support **200+ connectors by the end of 2021.** 
 * Airbyte’s connectors are **usable out of the box through a UI and API,** with monitoring, scheduling and orchestration. Airbyte was built on the premise that a user, whatever their background, should be able to move data in 2 minutes. Data engineers might want to use raw data and their own transformation processes, or to use Airbyte’s API to include data integration in their workflows. On the other hand, analysts and data scientists might want to use normalized consolidated data in their database or data warehouses. Airbyte supports all these use cases.

-You can deploy Airbyte in several ways, as [documented here](../deploying-airbyte/). Airbyte will then help you replicate data between a source and a destination. Airbyte offers pre-built connectors for both, you can see their list [here](../project-overview/changelog/connectors.md). If you don’t see the connector you need, you can [build your connector yourself](../contributing-to-airbyte/building-new-connector/) and benefit from Airbyte’s optional scheduling, orchestration and monitoring modules.
