Why3 offers a simple and versatile notation as a common interface to a large number of automated provers including all the leading SMT-LIB and TPTP compliant tools. The plug-in can function either in a local mode when all the provers are installed locally, or remotely as a cloud service. We discuss the experience of building the tool, the current status and the potential advantages of a cloud-hosted proof infrastructure.enRodin PlatformWhy3cloud computingtheorem provingPre-print of a book chapter
