Is deploying add-ins to a developer site supported with SPFX?

[Kevin McDonnell]

I am working on a SharePoint Framework webpart and packaging up as an add-in. Can I deploy this to a developer site collection in any way or only to the app catalog? Was hoping that I could deploy to a developer site for integration testing before putting in the app catalog but it was failing when I tried it.

I think you need to deploy it first into the app catalog. Once you're done, you can install the client-side solution on your site (dev site or whatever). Here is the process:

Thanks Luis. I have my app working with App Catalog but was hoping there was an easier pattern to deploy a test version for users without needing to have a separate dev tenant. Always found the developer site useful with the add-in model.
