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.
Meltano
Not familiar with Meltano? Meltano is your CLI for ELT+ that:
- Starts simple: Meltano is pip-installable and comes in a prepackaged docker container, you can have your first ELT pipeline running within minutes.
- Has DataOps out-of-the-box: Meltano provides tools that make DataOps best practices easy to use in every project.
- Integrates with everything: 300+ natively supported data sources & targets, as well as additional plugins like great expectations or dbt are natively available.
- Is easily customizable: Meltano isn't just extensible, it's built to be extended! The Singer SDK (for Connectors) & EDK (for Meltano Components) are easy to use. Meltano Hub helps you find all of the connectors and components created across the data community.
- Is a mature system: Developed since 2018, runs in production at large companies like GitLab, and currently powers over a million pipeline runs monthly.
- Has first class ELT tooling built-in: Extract data from any data source, load into any target, use inline maps to transform on data on the fly, and test the incoming data, all in one package.
