Excalidraw CLI

Excalidraw is an open-source virtual whiteboard for creating hand-drawn-style diagrams, wireframes, and other canvas-based drawings. It provides tools for shapes, arrows, lines, freehand drawing, image insertion, labeled and bound arrows, zooming, panning, undo and redo, dark mode, shape libraries, localization, and export to PNG, SVG, clipboard, or its open JSON format. The editor is available as an npm package for integration into applications. The hosted Excalidraw.com app adds real-time collaboration, end-to-end encryption, browser autosave with local-first behavior, offline PWA support, and shareable read-only links. The videos describe using Excalidraw to visualize Mermaid-generated diagrams and to manually map multi-step AI workflows with jobs, arrows, parallel lanes, checks, and human approvals.

Quickdraw is an MIT-licensed, open-source infinite-canvas whiteboard SDK for React, React Native/Expo, and plain JavaScript applications. It provides freehand pressure ink, highlighters, shapes, arrows, lines, text, sticky notes, images, selection and transformation tools, laser presentation pointers, themes, grids, palm rejection, and PNG export. Its data model emits JSON-safe diffs for real-time synchronization over an application-chosen transport, with support for persistence, undo/redo, and stroke-by-stroke replay. The project provides separate core, React, and React Native packages; the core is plain ESM with zero runtime dependencies and can run in modern browsers without a build step. The repository states that it is free for commercial use and has no license fee.

Mr. Mak Workspace is a local Windows desktop workspace for Codex CLI and Claude Code CLI. It combines real CLI chats with a project workspace for folders, research, images, files, Markdown documents, project reports, and saved project materials. The application provides chat history and tabs, agent activity indicators, file and folder insertion, project cards, previews for media files, and a right rail for project skills, knowledge, workflows, MCP connections, settings, and help. The repository includes fourteen project skills covering areas such as planning, handoffs, image references, media generation, Three.js, Blender, video inspection, and dictation. It can also provide an optional voice coordinator using Codex CLI and an OpenAI API key; external providers and MCP connections are optional and use the user's own accounts. The Windows installer includes the local Node service but does not bundle the supported CLIs or provider accounts. The native application targets Windows x64, while browser report previews can run elsewhere. Application code and original workflow documentation are MIT-licensed, with third-party skill materials retaining their original licenses.

tldraw is an open-source SDK for building infinite-canvas applications in React, including whiteboards, diagramming tools, and workflow-mapping interfaces. Its canvas engine supports custom shapes, tools, bindings, UI components, drawing, geometric shapes, rich text, arrows, snapping, media, image export, and runtime control through an Editor API. The repository also documents self-hosted real-time collaboration through @tldraw/sync, browser-based rendering, and canvas primitives for AI integrations. It can be installed as an npm package and includes starter kits for applications such as workflow builders, agent canvases, and AI chat interfaces. The starter kits are MIT-licensed.

reladraw is a text language and command-line tool for creating diagrams with relative positioning. It sits between automatic layout systems such as Mermaid, Graphviz, and D2 and manually positioned editors such as draw.io: users declare nodes, relationships, labels, and relative placement without specifying absolute coordinates. The parser and layout engine resolve the declarations into a diagram, while the tool reports issues such as overlaps, crossed edges, and text overflow without requiring a rendered preview. Its TypeScript CLI converts `.reladraw` files to SVG, and the repository also provides a browser version and an optional agent skill. The project is early-stage, its syntax is subject to change, and the code is licensed under Apache-2.0.
