SurveyJS is a set of four open-source JavaScript libraries that offer the benefits of a tailor-made in-house survey application, while considerably reducing the time and resources needed to deploy the system. These libraries are independent of specific server code or database requirements and seamlessly integrate with popular JavaScript frameworks, including React, Angular, Vue.js, jQuery, Knockout, and more. They are designed to communicate with any server that can handle JSON requests, ensuring compatibility with various server architectures and databases.
The product family is composed of:
- An open-source MIT-licensed rendering library that renders dynamic JSON-based forms in your web application, and collects responses.
- A self-hosted drag & drop form builder that features an integrated CSS-based theme editor and a GUI for conditional rules. It automatically generates JSON definitions (schemas) of your forms in real time.
- PDF Generator, a library that renders SurveyJS surveys and forms as PDF files in a browser;
- The Dashboard library that allows you to simplify survey data analysis with interactive and customizable charts and tables.

ContentTools
The ContentTools WYSIWYG editor can be seamlessly integrated into any HTML page through a straightforward process outlined in the getting started guide. Comprehensive API documentation and various examples are available for the entire ContentTools library suite. It includes step-by-step instructions for typical use cases, as well as more complex topics for developers creating their own editors. The ContentTools library collection is both free and open-source, and it is actively developed and maintained on GitHub. Users can easily reposition any content block on the page by dragging it to a new spot. For non-text elements like images and videos, simply click on the center of the element to drag it, while text elements require clicking and holding to initiate the drag action. This brief pause in the dragging process is designed to enable users to select text sections without unintentionally starting the drag function. Additionally, this functionality enhances the user experience by providing a flexible way to organize content efficiently.

Simditor
Simditor serves as a quick and user-friendly WYSIWYG editor, requiring a textarea element to get started since it is essential. This textarea can be defined using a jQuery Object, an HTML Element, or a Selector String. The accompanying simditor.css file is generated from a '.scss' source file through Sass compilation. For those looking to tweak the visual aspects of Simditor, modifications can be made directly in simditor.scss before regenerating the CSS file. Additionally, the .editor-style dictates the layout of the textarea, and you can adjust this file to achieve a different text presentation. If you're interested in adding unique interactions or features, it's worth exploring the extension library, where you can also develop your own extensions tailored to Simditor. The core functionality of Simditor is streamlined, with extensions providing various optional features, and we welcome the submission of your repositories! We encourage you to maintain a similar structure to the official extensions when creating your own. Furthermore, customization is possible during the initialization of Simditor by including various optional settings.
