Yeah, so it actually is using Jekyll right now for the engine, and we plan to support Pelican in the future. You can just buy our themes if you want, or you can use our engine to generate your posts in the cloud without all the setup.
We talked to 3 types of customers. The non-technical were largely disinterested. We're still too early for that. Agencies were all over this for their clients though. Great feedback from them.
