1. A first computing device, comprising: at least one processor circuit; and at least one memory that stores program code configured to be executed by the at least one processor circuit, the program code comprising: a build synchronizer configured to project a first build or design-time input generated by a first build environment hosted on the first computing device to a second build or design-time input of a second build environment hosted on a second computing device by automatically generating the second build or design-time input, the first build or design-time input having a first form and/or content suitable for the first build environment and not suitable for the second build environment, the second build or design-time input having a second form and/or content suitable for the second build environment, the first build environment being different than the second build environment, the first build or design-time input comprising a local asset referenced by a source code file and encoded in a first file format that renders successfully in the first build environment and does not render successfully in the second build environment, the second build or design-time input comprising a remote asset that is encoded in a second file format that does render successfully in the second build environment, and the automatically generating the second build or design-time input comprising selectively modifying one or more portions of the local asset.
