Meltano Singer SDK

The Tap and Target SDKs are the fastest way to build custom data extractors and loaders! Taps and targets built on the SDK are automatically compliant with the Singer Spec, the de-facto open source standard for extract and load pipelines.

Future-proof extractors and loaders, with less code

On average, developers tell us that they write about 70% less code by using the SDK, which makes learning the SDK a great investment. Furthermore, as new features and capabilities are added to the SDK, your taps and targets can always take advantage of the latest capabilities and bug fixes, simply by updating your SDK dependency to the latest version.
