Data & AnalyticsFree

Meltano is an open-source data integration and transformation platform built around the Singer standard for data connectors. It enables data engineers to build, manage, and orchestrate ELT pipelines using a CLI-first, version-controlled workflow. The platform has added AI-assisted configuration features that help engineers set up connectors and debug pipelines faster. Data teams at companies that want full control over their data infrastructure without vendor lock-in use Meltano as an alternative to commercial ETL tools like Fivetran or Stitch. Being open-source, Meltano allows custom connector development and self-hosted deployment. The active community maintains hundreds of extractors and loaders for various data sources and destinations.
