Singer FAQ
Is Singer free?
Yes, Singer is completely free and open source. It's a specification, not a product, so there's nothing to pay for - just use the community's taps and targets.
What is Singer?
Singer is an open source standard for data extraction. It defines how 'taps' (extractors) and 'targets' (loaders) communicate. Many modern data tools are built on Singer.
Singer vs custom ETL?
Singer provides reusable, community-maintained connectors. Instead of building custom extractors, you can often find a Singer tap that already exists. Faster implementation with less maintenance.
