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.
About Hevo Data
Hevo Data is a closed-source, managed ETL service that was created in 2017. As of September 2021, they have built 110 data connectors and have hundreds of customers. Hevo Data offers real-time replication to their destinations.
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.
Hevo Data offers connectors for more than 110 data sources, after 4 years since its inception. It supports the major data warehouses and databases as destinations. However, Hevo Data doesn’t support any data lakes. Hevo Data offers real-time replication, and not batch-based ones.
Customers can pay extra and request that Hevo Data build a new data source, but no one outside the Hevo team can build new data sources or make improvements to existing sources.
Hevo Data’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.
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.
Hevo Data offers preload transformations via code written in Python. Hevo Data can run transformation code for each event in the pipelines you set up. To perform transformations, you must edit the properties of the event object received in the transform method as a parameter.
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.
Hevo Data doesn’t provide any customizability, unfortunately.

The company doesn't provide training services, but tutorial videos can be found on YouTube.
Airbyte provides a one-month free trial or $400 worth of credits, whichever expires first. Airbyte’s pricing is credit-based, and you consume credits based on compute time and, to a lesser extent, egress costs. Airbyte positions itself as a self-service infrastructure company.
This pricing structure adapts well to all use cases, including database replication.
Airbyte doesn’t charge for failed syncs or normalization.
Airbyte offers adapted pricing to customers with large volumes.
Hevo Data offers a free plan limited to 1 million events per month, on a limited set of connectors. It discloses a pricing based on events synced that is in self-service until 300 million events per month.
Hevo Data’s volume-based pricing doesn’t adapt well with database replication use cases that involve the replication of millions of rows.
Standard plans range from $100 to $1,250 per month depending on scale, with discounts for paying annually.
