# What is Joule?

## Overview

Joule is a low-code platform for rapid use case development, offering out-of-the-box templates for **data sources and core processors**. Its declarative language allows users to easily define processing pipelines and integrate with data platforms. It achieves this by leveraging reusable components such as prebuilt and custom processors, metrics, analytics, and data integrations - letting you **focus on building solutions**, not rebuilding assets.

Joule is designed to be small, modular and powerful from the moment it is deployed.
