There is no export step

Every hosted builder ends the same way: the app works, and now you have to get it out. Export the zip, push to a repo, rebuild the runtime somewhere real, discover which parts only worked inside the sandbox.

On Hoody the agent built the app inside a container that was already the deployment. It has a public URL from birth. The database is a file on its disk. The process serving requests is the process the agent started. Point your domain at an alias and the prototype has the product's address.

Migration day never comes, because there was never an inside to migrate out of.
