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.

Rio Terminal
Rio is a terminal application developed using Rust, WebGPU, and the Tokio runtime, aimed at delivering an exceptional frames-per-second experience while also providing the flexibility to minimize GPU usage. The terminal's rendering engine utilizes a Redux state machine, ensuring that unchanged lines are not redrawn, thereby prioritizing a minimal rendering process most of the time. Furthermore, Rio is crafted to be compatible with a WebAssembly runtime, paving the way for future enhancements such as customizable tab systems through WASM plugins written in various programming languages. Additionally, Rio employs WGPU, which serves as a WebGPU implementation designed for non-browser environments and acts as a backend for Firefox’s own WebGPU implementation, allowing for a more efficient utilization of modern GPUs compared to WebGL alternatives. This focus on performance and customization makes Rio a versatile choice for terminal users seeking both speed and adaptability.
