# Adapters

Juttle's `read` source and `write` sink integrate with remote backends via adapters. This enables a Juttle program to interact with various types of external systems, including databases, streaming data sources, object storage systems, network APIs, and more.

### Built In Adapters

These adapters are included in the Juttle runtime and can be used in Juttle programs directly without special configuration.

* [http](../adapters/http.md)
* [http_server](../adapters/http_server.md)
* [stdio](../adapters/stdio.md)
* [stochastic](../adapters/stochastic.md)

### External Adapters

This is a partial list of adapters that are not included with the Juttle distribution but which can be optionally configured.

See the [Juttle README](https://github.com/juttle/juttle) for instructions on configuring external adapters to read from remote backends.
