TabTree

What it is

TabTree is a mind-mapping and whiteboard app that fits in a single HTML file. You double-click it and it runs — offline, with no account, no server and no subscription. One document reads six ways: mind map, kanban board, Gantt chart, page of notes, spreadsheet or full-screen presentation. Switch views; nothing is converted and nothing is lost.


One file	The entire app is one HTML file — no install, no build, no dependencies.
Offline, always	It runs from `file://`. Nothing leaves your machine.
Bought once	No subscription, no account, no telemetry, no expiry.
69 templates	Business Model Canvas, Lean Canvas, OKRs, roadmaps, agent specs… all of them
It leaves the building	PNG posts, carousel PDFs, MP4 flythroughs, or one `.html` file that carries the app and the map together.
Claude writes into it	The connector below is free with every licence.

This repository

TabTree itself is a commercial product and its source is not published here. This repository is the public face of it, and it holds three things that are genuinely useful on their own:

mcp/ — the full source of the Claude connector, free to use, copy, redistribute and modify (its own licence, no attribution required), and the same code published to npm as tabtree-mcp.
templates/ — the 69 template outlines in plain Markdown, each with a link that opens it live. Paste them into TabTree, or into any outliner.
screenshots/ — rendered by the real engine, not mocked up.

To use the app itself, try the demo — it is the whole application, running in your browser, with nothing to install.

Claude connector

Let Claude read your TabTree library and turn a conversation, a transcript or a spec into a real map on your disk. Local files, no account, nothing uploaded — the connector only ever sees the backup folder you point it at.

Claude Desktop — double-click, nothing to install. Download TabTree-Connector.mcpb and double-click it. Claude Desktop ships its own Node, so there is nothing else to install, and it asks you for your backup folder in a normal folder picker.

Claude Code, or any MCP client — one line:

Terminal

npx -y tabtree-mcp

Or in your client's config:

config.json

{
  "mcpServers": {
    "tabtree": {
      "command": "npx",
      "args": [
        "-y",
        "tabtree-mcp"
      ],
      "env": {
        "TABTREE_DIR": "/path/to/your/TabTree/backup/folder"
      }
    }
  }
}

Six tools: list_maps, read_map, search_maps, create_mindmap, create_board, propose_changes. It only ever writes new files — it never modifies or deletes one of your maps, and propose_changes drops a proposal the app applies only when you click. Full detail in mcp/README.md.

Screenshots

The same document as status columns — every card is still a node of the map.

Arrows stay attached to the boxes when you move them.

A map sent as one .html file: your reader double-clicks it, offline, no install.

Images and reasoning on one canvas.

Radial layout, dark theme.

Licence

Two different licences, and the distinction matters:

The connector in mcp/ is free to use, copy, redistribute and modify, for any purpose, with or without a TabTree licence — see mcp/LICENSE.md. It is given away on purpose.
The app is a commercial product sold at tabtree.app; its source is not in this repository, and its licence does not allow redistribution.
The template outlines are yours to copy and adapt freely.
