A computing resource service provider may provide developers with access to a build service configured to generate compilation artifacts associated with software development projects. The build service may obtain a build description and source code suitable for generating the compilation artifact. The build service may then cause one or more build resources to be provisioned and included in a build instantiation using computing resources of the service provider. The build instantiation may generate the compilation artifact, using the one or more build resources, based at least in part on the obtained source code. The developer may then be provided with access to the compilation artifact generated by the build instantiation.
