# Create and deploy integrations with Connect

- **About Connect**

  Connect lets you add functionality to your Project without needing to buy and maintain dedicated hosting or runtime environments.

  Connect provides a runtime environment for running small applications, referred to as [Connect applications](/connect/overview.md#connect-applications). Connect applications can be developed by anyone, and they are deployed to Projects using the Connect API.

- **Connect features**

  - Create integrations for use in private Projects or make them publicly available on the [Connect marketplace](/merchant-center/connect.md).
  - Publicly available integrations are [certified](/connect/certification.md) to ensure functionality, security, and compatibility.
  - commercetools provisions the infrastructure and runtime environment for running integrations.
  - Manage all aspects of Connect, from configuration to publishing and deployment, using the Connect API.
