What is Airbyte

airbyte logo
An open-source data integration platform, Airbyte is a popular choice for those building a modern data stack. Airbyte boasts its collection of ELT connectors as well as the ability to build custom ones in the platform, a differentiator from other no-code ELT tools. Because building custom pipelines requires coding knowledge, this special feature will only benefit data specialists with solid coding abilities. Airbyte is built to work well with DBT and SQL, so this is an important thing to note before deciding to use the tool.
In a review from Confessions of a Data Guy, he shares:
"If you don't have workloads that currently use DBT or fit well into that model, this probably isn’t the tool for you."
