A strict list of 15 currently verified free and open-source mind-mapping apps is not supported by the available project documentation. Four candidates have sources confirming open-source status: FreeMind, Freeplane, WiseMapping, and VYM. XMind is a useful adjacent option, but its download page does not establish an open-source license. The distinction matters: a free tier costs nothing to use, while open-source software makes its source code available under a license that grants defined rights to use, inspect, and modify it.
These options differ in how they run and what they emphasize. FreeMind and Freeplane are desktop projects; WiseMapping is browser-based and supports self-hosting; VYM focuses on tree-like visual structures. The comparisons below stick to claims documented by the projects, rather than presenting an untested ranking.

How to assess “free and open source” mind-mapping software
Before choosing an app, check its license as well as its price. A product may offer a no-cost plan without being open source. For example, FreeMind identifies its license as GNU GPL v2 or later (FreeMind project site); Freeplane describes itself as free and open source (Freeplane repository); and WiseMapping’s repository describes it as free and open source (WiseMapping source repository).

Four verified open-source options
FreeMind: a Java desktop mapper
FreeMind’s project site describes a Java-based mind-mapping program and identifies its license as GNU GPL v2 or later. It also describes a file mode that presents a computer’s folder structure as a map. That makes it a candidate to consider if you want a desktop mapping tool that can visualize folders, but check the project site for current download and compatibility details before installing it. FreeMind project site
Freeplane: mind mapping with a power-user orientation
Freeplane describes itself as free and open source, with uses spanning mind mapping, knowledge management, and project management. Its documentation says the feature set may appeal to power users; that is the project’s positioning, not an independent ease-of-use assessment. If you need more than a simple brainstorming map, its broader stated scope may be relevant. Freeplane repository · Freeplane documentation
WiseMapping: browser collaboration and self-hosting
WiseMapping’s source repository describes a browser-based application with real-time collaboration, self-hosting, and a desktop companion. It lists imports from Freeplane, XMind, and MindManager, and exports including PDF and SVG. Its official site identifies individual note-taking, collaborative planning, team brainstorming, and education as use cases.

Those capabilities do not mean every deployment works the same way: hosted service access and a self-managed installation are separate choices. Check current licensing language, desktop terms, and the setup requirements for the deployment you plan to use. WiseMapping source repository · WiseMapping official site
Rank #3
VYM (View Your Mind): tree-like maps and task management
VYM’s repository describes software for creating tree-like visual structures, organizing ideas, managing tasks, and using scripting. It lists Apple, Windows, and most Linux platforms. Treat that as the project’s stated platform coverage, not a guarantee for every current operating-system version; check its repository for current release and compatibility details. VYM repository
Adjacent free-tier option: XMind
XMind belongs in a broader comparison of free mind-mapping tools, not in a strict open-source shortlist based on the sources available here. Its official download page describes desktop and online offerings, teamwork, and an outliner, but does not establish an open-source license. Verify its current pricing and feature limits directly before relying on any no-cost tier. XMind download page
Compare the options by workflow
| Tool | What the cited sources establish | What to check before choosing |
|---|---|---|
| FreeMind | Java mind-mapping program; GNU GPL v2 or later; file mode can map folder structures (FreeMind project site) | Current release, supported operating systems, and compatibility |
| Freeplane | Project describes it as free and open source for mind mapping, knowledge management, and project management; documentation says features may appeal to power users (Freeplane repository and documentation) | Current platform and feature details for your needs |
| WiseMapping | Repository describes browser use, real-time collaboration, self-hosting, a desktop companion, specified imports and PDF/SVG exports; official site names individual, team, and education use cases (WiseMapping repository and official site) | Hosted-service terms versus self-managed deployment; current licensing and desktop terms |
| VYM | Repository describes tree-like structures, idea organization, task management, and scripting; lists Apple, Windows, and most Linux platforms (VYM repository) | Supported versions and current release details |
| XMind | Download page describes desktop and online offerings, teamwork, and an outliner; open-source status is not established by that page (XMind download page) | Current pricing, free-tier limits, and license |
Which one should you investigate first?
- For an explicitly documented GPL license: start with FreeMind’s project page and confirm its current download and compatibility details.
- For a broader desktop tool: review Freeplane’s stated scope and its power-user-oriented documentation.
- For browser collaboration or self-hosting: examine WiseMapping, paying attention to the difference between hosted and self-managed use.
- For tree-like maps, tasks, or scripting: look at VYM and confirm that its current release supports your system.
- For a free-tier product that also offers desktop and online use: consider XMind only after checking its current plan restrictions; the cited page does not establish an open-source license.
Why this is not a verified 15-product ranking
The cited project sources substantiate four open-source candidates, not 15 products with confirmed current licensing and availability. FreeMind’s alternatives page can suggest names for further investigation, but it is old and does not establish that listed projects remain available, maintained, free, or open source today.
