Not yet, we're probably on the way there as we're exposing all our pieces (connectors) as typesafe npm packages. But for now, flows are built with the no-code UI. The workaround is to write all your code in one main Code step in any flow. Our web IDE is VS Code so it's not too much different, and we can be self-hosted.

On the UI, you can customize the credentials with a connection variable which is what enables in-app product integrations. We have users who are doing this. Shoot me an email if you'd like to explore our approach: [e-mail]
