Xmind

MindSpark is an open-source, self-hostable mind-mapping application developed in vanilla JavaScript and distributed under the MIT license. It represents each map as a Markdown outline and keeps the canvas and Markdown editor synchronized in both directions, with imports and exports for formats including JSON, OPML, Markdown, PNG, PDF, Word, Mermaid, and GitMind. The editor provides automatic tree layout, drag-and-drop reordering, rich-text nodes, LaTeX rendering through MathML, an Excel-like node formula engine with functions such as SUM, AVERAGE, IF, ROUND, and SQRT, version history, read-only URL share links, and citations with DOI-based metadata retrieval from Crossref. Research, prompt-engineering, software, and AI-agent templates are included; map branches can also be compiled into prompts for Anthropic or OpenAI using a user-supplied API key. MindSpark can run locally with Node.js and SQLite, as a static site using a personal access token to save maps in a user's own Git repository, or with an optional Cloudflare Worker for OAuth, editable shared maps, access control, and real-time collaboration. Its repository also describes a separate MCP server for creating, reading, editing, and rendering maps through compatible AI clients.

SimpleMindMap is an open-source, framework-independent JavaScript library for developing web-based mind-map applications, together with a web application and a separately developed desktop client. The web application is built with the library, Vue 2.x, and Element UI; it supports local file operations, online use, self-deployment, and secondary development. The client supports mind maps and other diagram structures, including logical structure diagrams, organization charts, timelines, fishbone diagrams, and tables. It provides file import and export for formats including XMind, FreeMind, Markdown, TXT, XLSX, SVG, PDF, Mermaid, and HTML, and supports node content such as text, images, links, icons, notes, attachments, tags, formulas, and to-dos. The client is distributed for Windows, macOS, and Linux, while the library repository is described as being in low-maintenance status and the client and plugins are closed source and actively maintained.

AI Bridge is a Mac app for running AI coding agents such as Claude Code, Codex, Grok and OpenCode in separate projects and workspaces. Each workspace has its own instructions, context files, repositories and automations, while the app tracks agent states such as working, needs you, ready and asleep and collects questions, approvals and other requests in an Inbox. It can also place Kubernetes clusters, databases and Slack channels beside the agents; database changes and Slack replies wait for approval before execution or posting. The agents remain the real command-line tools running in local terminals and use the providers and subscriptions already configured by the user. Projects, workspaces, instructions, automations and logs are stored as plain YAML and Markdown under a user-owned folder on the Mac. The page says code, conversations and agent work stay on the Mac, with no usage telemetry; the app checks its licence periodically after sign-in and checks for updates at startup. It is free to start, with paid plans adding additional clusters, database servers, Slack channels and scheduled automations.

Mindwtr is a free, open-source, local-first task and idea management app built around the Getting Things Done (GTD) workflow. It captures tasks, ideas, and worries in an Inbox through desktop hotkeys, mobile widgets, share sheets, or voice input; guides users through sorting items into scheduled tasks, next actions, waiting-for items, projects, and Someday/Maybe; and provides Focus and guided weekly-review views. It supports projects with sections, areas, and manual task ordering, and is available for desktop, mobile, and web use. Data is stored on the device by default, with optional synchronization through iCloud, Dropbox, shared folders, a user-owned server, or WebDAV; the project states that it requires no account or subscription.

KIKUmap is a free, open-source native macOS menu-bar app and desktop widget for monitoring Claude, ChatGPT, and Claude Code sessions. It reads pinned chats and sessions, shows whether they are running, finished, waiting for approval or an answer, or stopped with an error, and lays them out as a draggable mind map organized by topics, colors, shapes, and tags. It also provides keyboard navigation, search, timelines for past and scheduled work, chat export and import for Claude conversations, PDF map export, backups, usage and time statistics, and optional notifications. The app supports macOS 13 or later on Apple silicon and Intel, uses Swift AppKit without Electron or a web view, and stores its data locally without requiring an account or tracking users.
