OPEN SOURCE (DLT)

pip install dlt and go

dlt is the most popular production-ready Python library for moving data. It loads data from various and often messy data sources into well-structured, live datasets.

Unlike other non-Python solutions, with dlt, there's no need to use any backends or containers. We do not replace your data platform, deployments, or security models. Simply import dlt in your favorite AI code editor, or add it to your Jupyter Notebook. You can load data from any source that produces Python data structures, including APIs, files, databases, and more.

Get started
import dlt
from dlt.sources.filesystem import filesystem

resource = filesystem(
    bucket_url="s3://example-bucket",
    file_glob="*.csv"
)

pipeline = dlt.pipeline(
    pipeline_name="filesystem_example",
    destination="duckdb",
    dataset_name="filesystem_data",
)

pipeline.run(resource)
VIBE CODE YOUR DATA PIPELINES

Unlimited data access

Can’t find the source you need in our documentation? You can easily define a custom source with our declarative REST API source. Our community builds 1000s of custom sources each month. We’ve developed various LLM rules and MCP servers that make converting your SaaS connectors or upgrading legacy pipelines with AI code editors simple. With the dlt ai setup command you can easily configure your favorite editor for maximum vibe coding success.

The current machine learning revolution has been enabled by the Cambrian explosion of Python open-source tools that have become so accessible that a wide range of practitioners can use them. As a simple-to-use Python library, dlt is the first tool that this new wave of people can use. By leveraging this library, we can extend the machine learning revolution into enterprise data.

Python and machine learning under security constraints are key to our success. We found that our cloud ETL provider could not meet our needs. dlt is a lightweight yet powerful open source tool we can run together with Snowflake. Our event streaming and batch data loading performs at scale and low cost. Now anyone who knows Python can self-serve to fulfil their data needs.
