About the services
Airbyte is the leading open-source ELT tool, created in July 2020. As of September 2021, they have built over 120 data connectors, and have 5,000 companies using them to sync data. Their ambition is to commoditize data integration by addressing the long tail of connectors through their growing contributor community. Airbyte released a Cloud offer in October 2021 with an infrastructure-type pricing model.
Stitch is a cloud-based platform for ETL — extract, transform, and load. More than 3,000 companies use Stitch to move data records every day from SaaS applications and databases into data warehouses and data lakes, where it can be analyzed with business intelligence tools. Stitch is a Talend company and is part of the Talend Data Fabric.
Pre-built connectors are the primary way to differentiate ETL / ELT solutions, as they enable data teams to focus only on the insights to build.
Within 14 months from inception, Airbyte already offers connectors for more than 120 data sources, and all major data warehouses, lakes and databases as data destinations.
All Airbyte connectors are open sourced and can be edited to address any custom needs the customers have. Airbyte users can leverage these connectors through the open-source edition or the Cloud offer.
Airbyte’s Connector Development Kit also enables their users to build custom connectors in a standardized way within 2 hours (instead of 2 days), and the Airbyte team and community can help in their maintenance.
About 30% of the connectors have been contributed by the growing community. Airbyte will provide a SLA for the certified connectors, but Airbyte’s ambition is also to provide a SLA for other connectors through the community and its participative model on the long tail of connectors, and to reach 1,000+ connectors in the next few years.
Airbyte will offer reverse-ETL connectors in 2022.
Stitch supports more than 100 database and SaaS integrations as data sources, and the major data warehouse and data lake destinations.
Customers can contract with Stitch to have them build new sources for them, and anyone can add a new source to Stitch using Singer, their open-source toolkit for writing scripts that move data.
Singer integrations can be run on Stitch to take advantage of their monitoring, scheduling and credential management features. However, most Singer integrations are now deprecating in quality. So you never know the quality of a tap or target until you have actually used it.
Airbyte is an ELT tool, and does not transform data prior to loading. Airbyte offers two options to get your data out of the box: a serialized JSON object and the normalized version of the record as tables.
Airbyte also offers custom transformations via SQL or through deep integration with dbt, allowing their users and customers to trigger their own dbt packages at the destination level right after the EL.
Stitch is also an ELT tool. It only provides the transformations required for compatibility with the destination, such as translating data types or denesting data when relevant. Aside from this, no extra transformation feature is offered.
Every company has custom data architectures and, therefore, unique data integration needs. A lot of tools don’t enable teams to address those, which results in a lot of investment in building and maintaining additional in-house scripts.
Airbyte’s architecture modularity implies that you can leverage any part of Airbyte. For instance, you can use Airflow’s orchestrator to trigger Airbyte’s ELT jobs.
You can also edit any pre-built connectors to your own specific needs, or even leverage the Connector Development Kit to build your own custom connectors in a matter of hours (instead of days) and have its maintenance shared with the community and the Airbyte team.
Airbyte’s promise is to address all your ELT needs and the long tail of integrations.
Stitch’s customers can leverage Singer to build custom Singer connectors that they can plug on their Stitch account. However, of the approximately 200 Singer connectors Stitch can leverage to adapt to their needs, most are low quality, as only the top connectors are maintained actively by the Singer community.
