Onlook is an integrated development environment designed for building user interfaces through a combination of visual manipulation and direct code synchronization. It provides a unified workspace where developers can modify application components, layouts, and styles within a graphical interface, with all changes automatically reflected in the underlying source code. By maintaining a live, bidirectional link between the rendered interface and the codebase, the platform ensures that visual edits are accurately translated into production-ready syntax. The platform distinguishes itself through i

Plate is a headless editor toolkit and framework designed for building custom rich text editing experiences. It provides a modular architecture that relies on a plugin-based system to manage document models, schema-driven node definitions, and state updates, allowing developers to assemble tailored content creation environments. The project distinguishes itself through a source-code injection pattern, where pre-built user interface templates and components are copied directly into the local project codebase. This approach ensures that developers maintain full control over the styling, markup,

This project is a UI component library and web layout framework providing pre-made interface elements and blocks for production-ready web applications. It functions as an AI design system that combines a collection of reusable components with a Model Context Protocol server to enable AI coding agents to discover and install interface elements. The system distinguishes itself through AI-driven automation, using the Model Context Protocol and schema-driven configurations to integrate design rules and installation commands directly into AI agents. This allows for the programmatic implementation

Mometa is an AST-based visual code editor and low-code metaprogramming tool. It provides a visual interface for modifying source code through abstract syntax tree manipulation, allowing for the insertion and deletion of code blocks via drag-and-drop actions. The project distinguishes itself through a visual source mapping system that links rendered DOM elements back to their original source code positions. It utilizes a real-time synchronization system and hot module replacement workflow to update application components in the browser without requiring a full page reload. The platform covers

Spartan is a development framework and design system toolset that combines a headless UI component library with a full-stack application scaffolder. It provides accessible, unstyled primitives that separate behavioral logic from visual styling, while automating the creation of development environments with end-to-end type safety across API and database layers. The project distinguishes itself by utilizing a component distribution model that copies styled source files directly into the local codebase to prevent dependency-based style locking. It also functions as an AI context server, using a
