Singer.io

Singer.io is an open-source ETL platform that provides a standardized specification for defining ETL scripts to move data between diverse data sources and destinations. It introduces a JSON-based message format and a straightforward process model that enables interoperability between data extraction and loading components. The platform consists of Singer taps, which are standalone programs that read data from APIs, databases, files, or other systems and emit the data in the Singer format. Complementary to taps, Singer targets consume these JSON streams and load the data into warehouses, databases, files, or other tools. Supported by an extensive ecosystem of taps and targets maintained by the community and sponsors, Singer.io empowers data engineers and developers to build composable, flexible data pipelines without depending on a single monolithic ETL platform, thereby simplifying data extraction and consolidation across organizations.
