Adapting web-based applications in a client/server web-based architecture is provided. At least a first version and a second version of a client/server application is provided. An adaptable application platform monitors a client and a server in a client/server web-based architecture for one or more performance characteristics. If one or more configurable performance characteristics exceeds a threshold, the adaptable application platform switches dynamically between executing the first version to executing the second version. The first version is server preferring and the second version is client preferring.
