DBML is a domain-specific language and schema definition language used for documenting database architecture and design. It provides a human-readable text format for defining database tables, columns, and relationships in a standardized way. The project functions as a relational schema parser and SQL schema generator. It transforms declarative design specifications into an abstract syntax tree for programmatic manipulation and converts these definitions into executable SQL statements across various database dialects. The system covers relational data modeling, database schema design, and arc

drawio is a web-based diagramming tool and cross-platform visual designer used for creating flowcharts, network maps, and technical schemas. It functions as a vector graphics editor and an XML-based diagramming engine that allows users to design and export scalable graphics. The software supports a wide range of technical design tasks, including infrastructure mapping for server layouts and the creation of visual aids for technical documentation. It enables the import of diagram files from other tools to facilitate cross-tool migration.

Asciiflow is a browser-based tool for creating text-based diagrams using keyboard characters. It functions as an ASCII diagram editor, enabling users to draw directly in the browser by typing characters onto a grid. The editor stores diagrams as a 2D character grid, allowing for precise row and column operations during drawing and editing. It renders these characters onto an HTML5 canvas for efficient pixel-level display, and supports a keyboard-driven input model that translates keystrokes into diagram elements without requiring a mouse. The tool includes an undo/redo command stack for rever

This project is a client-side rendering engine that transforms declarative, text-based syntax into visual diagrams directly within the browser. By utilizing a domain-specific language, it allows users to define complex structures—such as software architectures, process flows, and system behaviors—without the need for manual layout configuration. The library functions as a browser-based runtime that parses these definitions into intermediate abstract syntax trees, which are then processed by specialized engines to generate high-fidelity, resolution-independent graphics. The system distinguishe

This project is a browser-based collaborative design platform that provides a comprehensive workspace for interface design, interactive prototyping, and design system management. It functions as a vector graphics editor that enables teams to create, manage, and iterate on designs in real-time, utilizing a component-based inheritance model to ensure consistency across complex projects. The platform distinguishes itself through a deep integration of design and development workflows. It features a specialized developer handoff workspace that allows for the inspection of design properties, precis

react-diagrams is a framework for building interactive node-and-link diagrams and visual graphs within React applications. It functions as an interactive graph visualization tool and visual workflow designer, providing a system for rendering manipulatable canvases of connected nodes. The library is distinguished by its ability to act as a serializable state diagram manager, converting complex node layouts and connection states into storable data formats for session persistence. It further allows for custom behavior extensions to modify core logic and modules to implement project-specific func

This project is a diagram-as-code tool that transforms declarative text scripts into professional visual representations. It functions as a technical documentation generator, allowing users to define nodes, connections, and hierarchical relationships through a domain-specific modeling language that integrates directly into version-controlled developer workflows. The tool distinguishes itself through a highly modular architecture that decouples diagram definitions from spatial positioning. It features a pluggable layout engine that supports multiple arrangement algorithms, alongside a styling

This project is a programmable, high-performance drawing engine designed for building collaborative whiteboards, diagramming tools, and infinite canvas applications. It provides a reactive graphics runtime that manages complex canvas interactions, viewport animations, and input handling through a unified signal-based API. The framework is built on a schema-driven data store that maintains application state in a strictly typed, centralized record system, enabling efficient UI updates and persistent data management. The engine distinguishes itself through a highly modular architecture that supp

Open source library to build highly customazible interactive React diagrams with easy.

This project is a React-based framework for constructing interactive, node-based visual interfaces. It provides a platform for building canvases where users define, connect, and organize logical processes, data pipelines, or complex workflows through a graphical interface. By utilizing a modular component architecture, it enables the development of low-code environments, visual programming tools, and interactive diagramming applications. The framework distinguishes itself through a declarative approach where state changes automatically synchronize with the visual representation of nodes and e
