Design and diagrams decision
MindMeister
A competent developer can build a useful single-user mind-mapping editor and exporter in about a week, but reproducing MindMeister's enterprise compliance, certifications, real-time collaboration, integrations, and brand reach is not realistic for a small DIY project.

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. All MindMeister alternatives, with the arithmetic →
What a replacement has to do
- Create and edit node-based mind maps in a browser, save and load maps, export maps (PNG/PDF/Word), and apply automatic layout/styling.
What it still won’t have
- Real-time multi-user collaboration and presence
- Enterprise features: SAML SSO, ISO 27001 compliance, compliance exports/backups
- Hosted-in-Germany data residency and managed hosting guarantees
- Mobile first-class apps and polished integrations (MS Teams, Google Drive, MeisterTask)
- Meister AI map generation from prompts and file uploads
What remains hard
- Brand trust
Loved by 40 million+ mind mappers and visual thinkers
- Compliance and regulation
ISO 27001 certified
First-year cost
No published price
MindMeister does not publish a price we could read, so there is nothing to compare against. What building costs is below.

The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a single-user web mind-mapping app using React (TypeScript) for the frontend, Node.js/Express for the API, and Postgres for storage. Include: interactive canvas with node create/edit/delete, drag-and-drop reparenting, auto-layout (tree/organize branches), outline mode, themes/styles, per-user auth (email or OAuth), save/load map JSON with simple versioning, export to SVG/PNG/PDF and Word, and a small template gallery. Out of scope: real-time collaborative editing, SAML/enterprise SSO, hosted-in-country guarantees, mobile native apps, and AI-based map generation. Provide error handling, integration tests for API endpoints, and unit tests for core layout and persistence logic.
How we checked
How the score was reached
- Partly verdict base52

- 3/3 assessment runs agreed+4
- Hard moats found in the evidence-3
- Evidence score61
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.
