Meltano

Meltano is an open-source platform for the modern data stack, built around the Singer standard for data integration. It lets data engineers configure ELT pipelines with YAML files, run them from the command line, and combine them with dbt for transformations and other tools for orchestration — all in version control, so the whole data stack is defined as code.

Key Features

• Open-source ELT platform for the modern data stack
• Hundreds of Singer taps and targets
• Pipelines defined as code in YAML
• Works with dbt for transformations
• Plugin system for extending the stack
• Managed Meltano Cloud option

How it works

The platform is built for engineers who want an open, composable data stack. It offers hundreds of Singer taps and targets, a plugin system for adding tools, and Meltano Cloud as a managed option for teams that want hosting without operating the platform themselves. It is popular with teams that value transparency and control over their pipelines.

Meltano is free as open-source software, and Meltano Cloud is priced by quote. It is a strong pick for engineering-led data teams that want a code-first, open data stack, though it assumes comfort with the command line and YAML, and it is not a fit for business users who want a no-code tool.
