High Quality Content by WIKIPEDIA articles! Servoy is a development and deployment platform. Servoy is inspired on 4GL in terms of how applications are developed but unlike many 4GL`s does not have proprietary languages and/or databases but instead bases its language on open standards. Servoy consists of a GUI designer, is event-driven and runs scripts through JavaScript. Servoy allows applications to be deployed to both a native Smart client / Rich client and to a pure html Web client from the same codebase and user interface definitions.
