Is remote preview and update on the road map? (terraform Enterprise like functionality)

It is not on the roadmap at this point. We experimented with it in the past (if you look at old issues or code we had this concept of a PPC which was basically a service where you sent it a Pulumi program and it would run it to do your deployment) but we were not happy with the overall experience, so we killed that experiment. Would be interested in understanding what you want this for, and what the gaps vs doing the deploy or preview in your CI system would be. That’s what we do ourselves, and we’ve built some nice integrations around that workflow (like our GitHub app which will comment on pull requests with the results of Previews run in CI tied to a Pull Request).
