The invention discloses a processing method, a running method, equipment and application equipment for light applications. The processing method comprises the steps that a language framework of a target source code corresponding to a target light application is acquired; light application service information contained in the target source code is extracted according to the language framework; and the light application service information is stored as a description file in a designated format associated with the target light application so as to call a local control to provide corresponding light application service. According to the processing method, the light applications can automatically adapt to all kinds of different light application platforms to run, a developer or a server does not need to develop corresponding light applications according to different light application platforms for the same application service, and development and popularization cost of the light applications is lowered.
