SurveyJS vs. Parsley

SurveyJS comprises a collection of four open-source JavaScript libraries that provide the advantages of a customized, in-house survey application while significantly minimizing the time and resources required for deployment. These libraries function independently of specific server code or database needs, allowing for seamless integration with well-known JavaScript frameworks such as React, Angular, Vue.js, jQuery, Knockout, and others. They are built to interact with any server capable of processing JSON requests, thereby ensuring compatibility with a wide range of server setups and databases. This product suite includes: - An open-source library licensed under MIT that facilitates the rendering of dynamic JSON-based forms within your web application and captures user responses. - A self-hosted form builder featuring drag-and-drop functionality, an integrated CSS theme editor, and a graphical user interface for setting conditional rules; it also generates JSON definitions of your forms in real time. - A PDF Generator library that allows for the conversion of SurveyJS surveys and forms into PDF files directly in the browser. - The Dashboard library, which enhances survey data analysis through interactive and customizable charts and tables.
