gstack is an AI agent framework and development workflow system designed to automate the software development lifecycle. It coordinates specialized AI personas to manage tasks across product design, engineering management, and quality assurance, transforming product intent into technical specifications and final releases. The project is distinguished by its deep integration of headless browser automation and semantic code memory. It utilizes a persistent Chromium daemon for web scraping and visual auditing, and implements a searchable knowledge base that logs architectural decisions and repos

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

Diagrams is a diagram-as-code framework and infrastructure mapping tool used to generate system architecture visualizations via Python code. It functions as a programmatic wrapper for Graphviz, allowing users to define cloud services and their interconnections to create structured architectural layouts. The project specializes in cloud architecture visualization by mapping software components to a library of provider-specific icons. This approach enables the management of system designs within version control to track architecture changes over time. The library provides capabilities for conf

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

pyecharts is a Python visualization library and wrapper for the Echarts JavaScript engine. It translates Python data and configurations into JSON specifications to generate interactive web-based charts and graphs. The library provides specialized capabilities for geographic data mapping using a comprehensive library of map assets to visualize spatial information. It also includes utilities to capture rasterized snapshots of rendered web visualizations for export as static image files. The tool supports rendering interactive plots directly within data science notebook environments and exporti

PlantUML is a text-to-diagram generator that translates human-readable markup into structured graphical representations. It functions as a diagram-as-code tool, allowing users to create and maintain technical documentation, architectural models, and flowcharts by decoupling diagram content from visual layout. The project distinguishes itself through a comprehensive rendering pipeline that processes domain-specific markup into various output formats, including vector and raster graphics. It utilizes a graph-based layout engine to calculate spatial positioning, while a declarative styling layer

Macdown is a markdown text editor and HTML renderer designed for structured document composition. It provides a workspace for writing in lightweight markup syntax while simultaneously generating a live HTML preview of the rendered output. The editor distinguishes itself through a programmable interface, offering a command line utility to open files or pipe text directly into the application. It further supports extensibility via a plugin system that allows for the addition of custom features and functional modules at runtime. The application handles technical documentation requirements inclu

MiaoYan is a local Markdown editor and personal knowledge management tool. It functions as a system for writing and organizing documents stored as local files, supporting the creation of a connected information network through bidirectional links and backlinks. The project includes a specialized tool for converting Markdown documents into slide-based presentations by using specific content separators. It also provides a command-line interface for managing files, allowing users to create, search, and open documents without a graphical file explorer. The editor features a side-by-side live pre

mxgraph is a client-side graph visualization tool and JavaScript diagramming library. It functions as an SVG-based drawing framework used to create and render interactive diagrams directly within a web browser. The library enables the development of custom diagramming tools, such as network maps and flowcharts, by providing the means to draw and manipulate visual data structures. It focuses on client-side data visualization, allowing for the representation of complex node and edge relationships without requiring server-side rendering.
