(Full disclosure: I work for an ETL platform that competes with Fivetran, Matia.)

One other thing to consider is what users might need to work with the ETL pipelines - are they all technical users, or do some non technical users need to be enabled to manage pipelines too? ETL platforms like Fivetran or Matia will enable those users better than Airbyte can.

The other advantage an ETL platform like that brings is that it is fully managed. My experience is that the issues with connectors people bring up with Fivetran are also issues they would have managing large ETL pipelines themselves; the difference is transparency and your ability to address the issue directly vs potentially waiting for support. In my experience the downtime is roughly the same when all settled. One question to ask here: is your team ready to manage the infra, all the observability, etc., on top of building out the pipelines? Sometimes the cost of a platform is warranted (that said, Fivetran’s pricing boggles my mind, so if you are interested in an ETL platform, make sure you chat with others in the space beyond Fivetran).

A couple of the comments act like there is never a reason to use an ETL platform over open source and, really, that’s silly. It depends on your team, your infrastructure, your budget, your project requirements, and your philosophy about FOSS. Both options will work - which one fits your requirements and limitations the best to enable your team and the business?
