Key Distinctions Between Airbyte & Fivetran

1. Connectors

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 3 years from inception, Airbyte already offers connectors for more than 300 data sources, and 50 destinations including all major data warehouses, lakes and databases. 

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 no-code Connector Builder also enables their users to build custom connectors in a standardized way within 10 minutes (instead of 2 days), and the Airbyte team and community can help in their maintenance. 

More than 50% 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 2024. 


Fivetran offers connectors for about 200 data sources. It supports the major data warehouses and databases as destinations. However, Fivetran doesn’t support any data lakes.

Customers can pay extra and request that Fivetran build a new data source, but no one outside the Fivetran team can build new data sources or make improvements to existing sources. 

Fivetran’s customers often end up having to build and maintain custom connectors in-house with their own data engineering teams to address all their custom needs.

2. Transformation


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 and through deep integration with dbt, allowing their users and customers to trigger their own dbt packages at the destination level right after the EL. 


Fivetran is an ELT tool, and does not transform data prior to loading, either. It offers its own opinionated normalization out of the box, and recently added support for post-load transformations via copy-and-paste SQL and dbt.

3. Customizability

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 no-code / low-code Connector Builder to build your own custom connectors in a matter of minutes (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.


Fivetran released cloud functions to let their customers edit connectors by writing small function to fetch data using Go, Java, Node.js, Python, C# or F#. Customers will need to host their functions on a serverless platform.

4. Support & docs

Data integration tools can be complex, so customers need to have great support channels. This includes online documentation as well as tutorials, email and chat support. More complicated tools may also offer training services.


Airbyte provides in-app chat support with an average time to respond of less than 1 hour. 

Their documentation is comprehensive and full of tutorials. Airbyte also has a Slack and Discourse community where help is available from the Airbyte team, other users or contributors. 

Airbyte does not provide any training services. 


Fivetran provides support through an in-app form, but does not offer chat support.

Their documentation is comprehensive, but Fivetran doesn’t offer a Slack or Discourse community. 

Fivetran does not provide any training services. 

5. Pricing


Airbyte provides a 14-day free trial or $1,000 worth of credits, whichever expires first. Airbyte’s pricing is credit-based, and you consume credits based on volume with a different price for APIs, databases and files, which enables it to adapt well to all use cases, including database replication. 

Airbyte doesn’t charge for failed syncs or normalization. 

Airbyte offers adapted pricing to customers with volume discounts.


Fivetran offers a free tier limited to 500 thousands monthly active rows,  i.e., rows that are added or edited in a given month. Fivetran also provides a 14-day free trial on any of their paid plan. It discloses a pricing based on monthly active rows.

Fivetran’s volume-based pricing doesn’t adapt well with database replication use cases that involve the replication of millions of rows.
