1. A computer-implemented method, comprising: determining, by a development tool, a set of parameters for estimating a computational cost for hosting code on an open platform, the set of parameters determined based at least in part on a desired grade of the code; evaluating, by the development tool, an actual grade of the code based at least in part on the set of parameters; in response to a determination that the actual grade meets or exceeds the desired grade, submitting the code to the open platform at the desired grade; and in response to a determination that the desired grade exceeds the actual grade: receiving a modification to the desired grade such that the actual grade meets or exceeds the modified desired grade; determining an other set of parameters for estimating the computational cost, the other set of parameters determined based at least in part on the modification; and submitting the code to the open platform based at least in part on the computational cost estimated according to the other set of parameters.
