Techniques that facilitate re-hosting a subset of a serverless application are provided. In one example, a system includes an interface component, a rewriter component and a broker component. The interface component receives identifier data from a computing device that identifies a portion of a serverless application to be re-hosted by the computing device. The computing device is in communication with the serverless computing system via a network device. The rewriter component rewrites the serverless application to allow the first portion of the serverless application to be executed by the computing device and another portion of the serverless application to be executed by the serverless computing system. The interface component re-routes the first portion of the serverless application to the computing device to facilitate a debugging session for the first portion of the serverless application that is performed by the computing device.
