Synchronous side-by-side extensibility

A system and method providing a single entry point for implementing software extensions across multiple different software applications. In one embodiment, the method may include retrieving an indication of an extension point offered by a cloud application, the extension point being defined by a signature including a name and one or more parameters; generating one or more extension point implementations of the extension point by configuring custom code that fulfills the signature of the extension point; and sending, to the cloud application, an indication the extension point is active for requesting an execution of the one or more extension point implementations to be executed apart from the cloud application.
