Simple, Composable, Open Source ETL

Singer powers data extraction and consolidation for all of your organization’s tools: advertising platforms, web analytics, payment processors, email service providers, marketing automation, databases, and more.

See It in Action

Singer is an open-source standard for writing scripts that move data.

It describes how data extraction scripts—called “Taps” —and data loading scripts—called “Targets”— should communicate, allowing them to be used in any combination to move data from any source to any destination. Send data between databases, web APIs, files, queues, and just about anything else you can think of.

Try it

For example, these two simple commands pull currency exchange rate data from Fixer.io into a CSV file:

	    	› pip install target-csv tap-fixerio
		› tap-fixerio | target-csv
  		    INFO Replicating the latest exchange rate data from fixer.io
  		    INFO Tap exiting normally
		› cat exchange_rate.csv
