MindNode

A capable developer can replicate the core mind-mapping and outline workflow and basic sharing in about a week, but reproducing MindNode's native Apple polish, iCloud private sync, Vision Pro features, on-device AI, and years of product polish is impractical for a one-person open-source replacement.

Open-source builds that already do this

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.

What a replacement has to do

  • Create and edit node-based mind maps, switch to an outline view, save/load documents, and export/import common formats.

What it still won’t have

  • Native macOS / iOS / Vision Pro UI polish and platform-specific integrations
  • iCloud-backed private sync and encryption tied to Apple accounts
  • On-device private AI that runs locally on Apple hardware
  • App Store distribution, Apple Watch and Vision Pro immersive features
  • Years of product polish and integrated sticker/theme assets

What remains hard

  • Brand trustMindNode is fully supported by our users and owned by our founder.
  • Brand trust18+ years of refinement creating the perfect balance of simplicity and capability.

Runnable build prompt

Not run yet
Build a single-developer minimal web mind-mapping app using React + TypeScript for frontend, Konva or SVG for the canvas, Node.js + Express for a simple backend, and Postgres (or SQLite) for storage. Implement: 1) interactive node graph (create/move/connect/edit/delete nodes, keyboard shortcuts), 2) synchronized outline view that edits the same document model, 3) import/export OPML and Markdown and JSON document save/load, 4) attach images to nodes and call an external image-background-removal API, 5) simple shareable document URLs and optional realtime presence using WebSockets. Out of scope: native macOS/iOS/Vision Pro apps, iCloud sync, App Store packaging, on-device AI. Include error handling, input validation, and automated tests for core document model and import/export; provide a Dockerfile and a README with deployment steps.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
