Meltano

Meltano is an open-source ETL platform built on Singer foundations, engineered for cloud scale, efficiency, and reliability. It supports 600+ pre-built connectors for extracting and loading data from SaaS applications, REST APIs, databases, and files. Meltano integrates natively with dbt for transformation and Elementary for data validation, and supports orchestrators including Apache Airflow and Dagster. The platform enables pipelines-as-code with full Git-based version control, CI/CD, and governed environments. Originally spun out of GitLab in 2021, Meltano is now an open-source project maintained by Matatika.
