Open Source TypeScript User Interface (UI) Software - Page 6

critique is a beautiful terminal-oriented user interface tool for reviewing git diffs that makes inspecting source control changes more intuitive and readable directly from the command line. The tool provides a styled, split-view diff layout with syntax highlighting and word-level diffing, which gives developers clear insight into what has changed in each file beyond simple line additions or deletions. It supports viewing diff ranges across commits, staged versus unstaged changes, and even comparisons between branches, turning the diff output into a more interactive, readable experience than traditional git diff. Critique is built with a terminal UI foundation and can also generate a web preview of diffs by converting ANSI escape codes into styled HTML, which can be shared temporarily via a cloud worker for collaborative review.

gluestack-ui is a modern, universal UI component system designed for React, React Native, and Next.js applications, built around a modular “copy-paste” philosophy that gives developers full ownership of their code. Instead of installing a monolithic dependency, developers can selectively copy only the components they need directly into their codebase, avoiding unnecessary bloat and vendor lock-in. The library is deeply integrated with Tailwind CSS through NativeWind, allowing a consistent styling approach across both web and mobile platforms. It emphasizes composability and flexibility, enabling developers to customize every aspect of a component, including behavior, structure, and styling. The architecture supports React Server Components and modern TypeScript tooling, making it suitable for scalable and high-performance applications. Accessibility is also a core principle, with components designed to follow best practices such as ARIA support and keyboard navigation.

ikun-ui is a Svelte-based UI component library built on top of UnoCSS, designed to help developers create visually appealing and highly customizable web interfaces with minimal effort. It provides a wide range of prebuilt components, including navigation elements, feedback components, data display tools, and layout utilities, all optimized for modern web applications. The library emphasizes flexibility through its UnoCSS preset system, allowing developers to configure themes, styles, and design tokens using attribute-based customization. IKun UI also supports integration with Iconify, giving developers access to a vast library of icons for enhancing interface design. It includes built-in support for dark mode and theme switching, making it easy to adapt applications to different visual preferences. Designed for performance and ease of use, it works seamlessly with Svelte and modern browsers, ensuring smooth rendering and responsiveness.

Open Source Library for Angular Web Apps to integrate a material user interface built for firebase authentication. Angular UI component for firebase authentication. This library is an angular module (including angular components and services) that allows to authenticate your users with your firebase project. NgxAuthFirebseUI is compatible with angular material and angular flexLayout. It uses a responsive and accessible web design UX/UI from google material concepts and components (supporting desktop, tablet and mobile view) incl. smooth animations for a better UX. Pick up your own theme! change the primary, accent and warn colors whenever you need (e.g to support light and dark themes) Super easy to use with an angular based project (project that is created with the angular-cli) Configure your authentication providers in runtime.

react-chat-elements is a React-based UI library specifically designed for building chat and messaging interfaces with minimal effort. It provides a set of prebuilt components such as message bubbles, chat lists, input fields, avatars, and typing indicators, all styled to resemble modern messaging applications. The library is intended to accelerate development by offering ready-to-use elements that handle common chat interface requirements without requiring developers to design them from scratch. It supports customization through props and styling options, allowing developers to adapt the components to match their application’s branding and behavior. The components are designed to be modular and composable, enabling developers to build complex chat interfaces by combining smaller building blocks. It is particularly useful for applications that include messaging features, customer support chats, or real-time communication tools.

react-native-graph is a Line Graph implementation based on the high-performance 2D graphics rendering engine "Skia". It's used in the Pink Panda Wallet app to power thousands of token graphs every day. Animations are ran using the Skia animation system and are fully natively interpolated to ensure best possible performance. If animated is false, a light-weight implementation of the graph renderer will be used, which is optimal for displaying a lot of graphs in large lists.

A flexible way to handle safe areas, also works on Android and the Web! This library currently has experimental support for the new react-native architecture. Note that there will be breaking changes and only the latest version of react-native will be supported. This library has 2 important concepts, if you are familiar with React Context this is very similar. The SafeAreaProvider component is a View from where insets provided by Consumers are relative to. This means that if this view overlaps with any system elements (status bar, notches, etc.) these values will be provided to descendent consumers. Usually, you will have one provider at the top of your app. Consumers are components and hooks that allow using inset values provided by the nearest parent Provider. Values are always relative to a provider and not to these components.

Taxonomy is an open-source web application project built with modern JavaScript frameworks to demonstrate how a fully featured application can be implemented using the newest capabilities of Next.js and React. The project was created by the shadcn-ui ecosystem as an experiment to explore modern architecture patterns such as server components, the Next.js app router, and modular UI component design. Rather than serving as a simple template, Taxonomy acts as a real application example that includes authentication, subscription management, documentation pages, and blogging functionality. The application uses a modern development stack including TypeScript, Tailwind CSS, and UI components based on Radix UI to build accessible and responsive interfaces. It also integrates backend functionality through Prisma ORM and database services while supporting API routes and middleware for server-side logic.

spartan is a modern, experimental full-stack toolkit designed to enhance Angular development by combining a flexible UI component system with a broader application stack. It is structured as a monorepo that includes both a UI library and a full-stack solution, enabling developers to build complete applications with consistent tooling and design patterns. One of its defining characteristics is its inspiration from libraries like shadcn/ui, emphasizing ownership of code rather than heavy abstraction, which allows developers to fully customize and extend their components. The UI layer is built on accessible, unstyled primitives that can be enhanced with styled layers, giving teams control over both accessibility and visual design without being locked into a rigid theme. Spartan integrates well with modern Angular tooling such as Nx and Tailwind CSS, making it suitable for scalable, enterprise-level projects.

ui-box is a low-level React UI primitive library that provides a simple and performant way to build styled components using a CSS-in-JS approach. Instead of relying on traditional CSS files or complex styling systems, ui-box allows developers to apply CSS properties directly through React props, making styling more intuitive and composable. The core concept revolves around a single Box component that can render different HTML elements while accepting a wide range of style-related properties. This approach enables developers to create reusable components without needing additional wrapper elements or class-based styling, improving both readability and maintainability. The library is designed to be fast and extensible, focusing on minimal overhead while still offering powerful styling capabilities. It also supports advanced features such as pseudo-selectors and conditional styling through prop-based configurations. ui-box serves as the foundational layer for more complex UI systems.
