 Unlike other solutions, with dlt, there's no need to use any backends or containers. Simply import `dlt` in a Python file or a Jupyter Notebook cell, and create a pipeline to load data into any of the [supported destinations](dlt-ecosystem/destinations/). You can load data from any source that produces Python data structures, including APIs, files, databases, and more. `dlt` also supports building a [custom destination](dlt-ecosystem/destinations/destination.md), which you can use as reverse ETL.
