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.

Headless UI
Headless UI is a collection of fully accessible, completely unstyled UI components that are designed to work seamlessly with Tailwind CSS. It provides a variety of components for both React and Vue frameworks, all of which prioritize accessibility by following WAI-ARIA design patterns and offering comprehensive keyboard navigation capabilities. Since these components come without any inherent styling, developers have the liberty to customize their appearance, allowing for a perfect match with any design aesthetic. Headless UI components utilize data attributes and render props to expose state information, giving developers the ability to style components conditionally based on states like focus, open, selected, or disabled. This innovative approach guarantees that the components remain both adaptable and accessible, making them ideal for crafting tailored, high-quality user interfaces. By using Headless UI, developers can effortlessly construct intricate UI elements, such as modals, dropdowns, and tabs, while maintaining a strong commitment to accessibility and design versatility. Ultimately, this library empowers developers to focus on functionality and user experience without being constrained by predefined styles.

Once UI
Once UI is an open-source design system and component library tailored for Next.js, complemented by a corresponding design system in Figma, featuring a versatile style system, over 100 pre-built UI components, and more than 75 copy-paste blocks to expedite the creation of web applications. It caters to both basic static websites and more intricate applications, offering pre-constructed, ready-to-deploy templates for various needs, including portfolios, documentation sites, blogs, ecommerce platforms, and dashboards, available in both free and Pro versions. The framework promotes a "component-first" approach to development, allowing developers to avoid the tedious task of manually coding with utility-class-heavy styling, which is common in certain CSS frameworks; instead, they can leverage semantic variables and components that utilize design tokens for consistent visual aesthetics. For those familiar with utility-class frameworks or component libraries seeking a quicker development process with reduced dependencies, Once UI streamlines the UI building process, ensuring that design quality and accessibility remain uncompromised. This innovative approach not only enhances productivity but also empowers creators to deliver sophisticated designs effortlessly.
