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.

Realm
Realm is an innovative, mobile-centric open-source object database specifically engineered to operate seamlessly on phones, tablets, and wearable devices. By offering a straightforward, object-oriented data model, it eliminates the necessity for an Object-Relational Mapping (ORM) layer, allowing developers to create models using standard classes in popular programming languages such as Swift, Java, Kotlin, C#, JavaScript, Dart, and C++. Its design prioritizes high efficiency and minimal memory footprint through techniques like zero-copy architecture, lazy loading, and multi-version concurrency control (MVCC), ensuring safe operations across multiple threads. Realm's live objects and collections synchronize automatically across threads, providing a foundation for reactive programming methodologies. Furthermore, it allows for the establishment of intricate data structures by enabling relationships between objects through links and backlinks. Developers can also take advantage of tools like Realm Studio to explore and modify local Realm databases, facilitating integration with a variety of platforms, including React Native, Flutter, Xamarin, and Node.js. This adaptability makes Realm a compelling choice for developers looking to manage data efficiently in their mobile applications.
