Page Agent
JavaScript in-page GUI agent. Control web interfaces
Page Agent is an open-source in-page AI agent framework that allows developers to control and interact with web interfaces using natural language directly within the browser. Unlike traditional browser automation tools, it operates entirely through in-page JavaScript, eliminating the need for browser extensions, headless browsers, or external automation environments. The system enables users to manipulate the DOM through text-based commands, allowing complex workflows such as form filling, navigation, and UI interaction to be executed through simple natural language instructions. Page Agent is designed to integrate seamlessly into existing web applications, making it possible to embed AI copilots into SaaS platforms without major backend changes. It supports a bring-your-own-LLM approach, allowing developers to connect their preferred language models to power the agent’s reasoning capabilities. -

Crazy Eddies GUI System (CEGUI)
A fast, powerful and adaptable GUI solution
Crazy Eddie's GUI (CEGUI) system is a graphical user interface C++ library. It was designed particularly for the needs of videogames, but the library is usable for non-game tasks, such as any other type of applications (rendering/visualisation/virtual reality) and tools. It is designed for user flexibility in look-and-feel, as well as being adaptable to the user's choice in tools and operating systems. Established in 2003, CEGUI sees continual, active development and remains one of the most powerful and most popular options for developers requiring an adaptable and efficient GUI solution. CEGUI is fully supported by the developers that created - and continue to develop - the library, and who are accessible via the project's dedicated internet forums and IRC channel. For more information, more screenshots and for news, check out out our homepage: http://cegui.org.uk The repository is now at bitbucket (including our issue/bug tracker): https://bitbucket.org/cegui -

Eagle Mode
Zoomable user interface (ZUI) with file manager, file viewers and more
Eagle Mode is a zoomable user interface (ZUI) with file manager, file viewers, games, and more. This project is about a futuristic style of human-computer interaction, where the user can visit almost everything simply by zooming in. It features a portable C++ toolkit API for developing such ZUIs, and it features the Eagle Mode application, which provides a virtual cosmos with plugin applications. The most important one is the professional file manager with its rich, scriptable command set. It integrates file viewers for most of the common file types, as well as an audio and video player. Furthermore, the virtual cosmos contains a chess game, a netwalk game, a 3D minesweeper game, a multi-function clock, a stock watchlist, some fractals, and a Linux kernel configurator in form of a kernel patch. -

zag
Finite state machines for building accessible design systems and UI
A collection of framework-agnostic UI components patterns like an accordion, menu, and dialog that can be used to build design systems for React, Vue, and Solid.js. Simple, resilient component logic. Write component logic once and use it anywhere. Built-in adapters that connect machine output to DOM semantics in a WAI-ARIA-compliant way. Component logic is largely JavaScript code and can be consumed in any JS framework. Zag machine APIs are completely headless and unstyled. Use your favorite styling solution and get it matching your design system. Finite state machines for building accessible design systems and UI components. Works with React, Vue and Solid. -

Claude Island
Claude Code notifications without the context switch
Claude Island is a macOS menu-bar utility that elevates your command-line AI sessions by turning them into dynamic, always-visible notifications that live in your laptop’s notch area or menu bar. Rather than constantly switching back to a terminal window to check the status of Claude Code sessions, Claude Island monitors session state hooks and displays ongoing activity, permission requests, and chat history right from a lightweight overlay. When a Claude session triggers a prompt for tool execution or needs user approval, the Dynamic Island-style widget expands with actionable buttons, letting you approve or deny actions instantly without breaking your workflow. It also lets you track multiple active sessions in real time and view conversation history in markdown format directly in the UI, streamlining multitasking for developers who use the Claude Code CLI. -

OpenUI
The Open Standard for Generative UI
OpenUI is an open-source framework focused on enabling AI-driven generation and manipulation of user interfaces through natural language and programmatic inputs. The project aims to bridge the gap between design and development by allowing users to describe UI components and layouts in plain language, which are then translated into structured code or interactive components. It leverages modern AI models and frontend technologies to dynamically generate UI elements that can be customized, refined, and extended within development workflows. OpenUI is particularly useful for rapid prototyping, as it allows developers and designers to iterate on interface ideas without manually writing all the underlying code. The framework also supports extensibility, enabling integration with existing design systems and component libraries. By combining AI-assisted generation with developer control, OpenUI provides a hybrid approach to building interfaces that balances automation with customization. -
