Batch ELT & Connectors

dlt is an open-source Python library for the extract-and-load stage, inferring schemas, normalising nested data, and handling incremental loading — installed with pip and run wherever Python already runs.

Meltano is an open-source ELT orchestrator that assembles pipelines from Singer taps and targets declaratively in version-controlled YAML, with a hub cataloguing over 600 community-maintained connectors.

Estuary Flow is a data movement platform built on a streaming core, capturing from databases via CDC and from SaaS APIs, then materialising continuously into warehouses and lakes rather than on a schedule.

Hevo Data is a managed no-code data pipeline platform with over 150 connectors across SaaS applications, databases, and storage, billed by event — each row inserted, updated, or deleted at the destination.

Sling is a data movement tool distributed as one Go binary, moving data between databases, warehouses, and file storage from the command line or a pipe, with a managed platform available above it.

Matillion is a commercial data integration platform with a visual pipeline builder, loading data into cloud warehouses and pushing transformation work down to the warehouse's own compute rather than processing it separately.

Airbyte is a data integration platform that syncs data from APIs, databases, and files into warehouses and lakes, available self-hosted or as a managed cloud service.

Fivetran is a commercial, fully managed data movement platform with maintained connectors, automated schema handling, and consumption-based pricing.
