you mean deploy app and every thing else including infra is done by the PaaS component AND the platform is built using Pulumi ? Curious on why do you need it using Pulumi / Anyways, pulumi deployments comes close to it i think but not aware of any thing specific. We have built a commercial product using Pulumi automation API that is kind of SaaS for infra / so no coding required, use blueprints etc. If you are interested in knowing more, you can dm me.
