Free projection mapping software exists, but “free” can mean several very different things: open-source software with no watermark, a non-commercial edition, a demo that adds a watermark, or a limited free tier that withholds saving or commercial use. The right choice depends on whether you are learning, doing paid work, or trying to run a show that has to work reliably in front of an audience.
- Best truly free/open-source starting point: MapMap.
- Best advanced free non-commercial environment: TouchDesigner Non-Commercial.
- Best older free desktop mapper: VPT 8—useful, but development stopped after its final release.
- Best paid HoloMapper alternative to recurring subscriptions: HoloMapper, if Windows/Linux and live NDI/Spout fit your workflow.
Free projection mapping software compared
| Tool | Free model | Best for | Main catch |
|---|---|---|---|
| MapMap | Free + open source | Learning, small projects, artists | Smaller feature set than commercial suites |
| TouchDesigner Non-Commercial | Free for non-commercial work | Interactive and generative systems | 1280×1280 image-resolution limit and not licensed for paid work |
| VPT 8 | Free | Classic multi-layer mapping experiments | Final release was in 2018; compatibility/support are not guaranteed on modern systems |
| Resolume demo | Evaluation/demo | Testing a VJ + mapping workflow | Not a clean-output free production license |
| MadMapper demo/trial | Evaluation | Testing professional mapping tools | Not a permanent free production workflow |
| HeavyM demo | Demo mode | Testing accessible show creation | Demo limitations apply |
1. MapMap — best truly free open-source choice for most beginners
MapMap is a free, open-source video-mapping application aimed at artists and small teams. Its official site lists Windows, macOS and Linux support, and its documentation covers media sources, layers, shapes, full-screen output, saving/loading projects, and OSC control. The project has also seen renewed repository activity in 2026, which makes it more interesting than old “free software” lists that quietly point to abandoned downloads.
MapMap is a good first choice when you want to understand the basic mental model of projection mapping—source media on one side, output geometry on the other—without buying anything. It is not trying to be a full VJ performance environment or a deep media server, and that simplicity is an advantage for learning.
2. TouchDesigner Non-Commercial — best free option for interactive experiments
TouchDesigner is a visual programming environment rather than a focused mapper. Its Non-Commercial license is free for personal/non-commercial use, with a 1280×1280 image-resolution limit and restrictions that prevent using that edition for compensated work. In exchange, you get an enormous real-time toolbox for procedural graphics, cameras, sensors, audio analysis, data, networking and custom logic.
Choose TouchDesigner if the projection is only one part of a bigger interactive system. If your goal is simply “put this video on that wall and warp it into place,” the learning curve can be much larger than the mapping task itself.
3. VPT 8 — capable classic freeware, but frozen in time
VPT (Video Projection Tools) earned a long-running reputation as a powerful free mapping environment. The developer describes VPT 8 as the final version and notes that development stopped after its 2018 release, so there is no guarantee that it will work reliably on newer operating systems and hardware. That does not make VPT useless—it still has a lot of capability—but it does change how you should evaluate it for a show in 2026.
For experimentation on compatible hardware, VPT remains worth knowing. For a commercial install or an event with a hard deadline, software that is still actively maintained is easier to recommend.
4. Resolume, MadMapper and HeavyM demos are useful—but they are not the same as free production software
Professional projection-mapping applications commonly provide demos or trial modes so you can test the workflow and hardware before paying. That is excellent for evaluation, but a demo that watermarks output, expires, or restricts production use should not be grouped with genuinely free software.
If your project is a one-night show, gallery opening, client job or installation, check the current license terms before you build your entire workflow around a demo.
When a paid mapper is worth it
If you have reached the point where you need reliable project saving, current Windows/Linux support, mesh warping, Bezier curves, media layers, clean projector output, or live NDI and Spout workflows, paying for a focused mapper can save more time than continuing to work around free-tool limitations.
HoloMapper is our own option in that category. It is available through Steam for Windows and Linux/SteamOS, supports Steam Deck workflows, and is sold as a one-time purchase rather than a subscription. It is still in Early Access, so buyers should evaluate the current feature set—not future plans—before choosing it.
How to choose a free projection mapping tool
- Learning geometry: start with MapMap.
- Interactive art: learn TouchDesigner Non-Commercial.
- Older desktop experimentation: try VPT if it runs well on your machine.
- Evaluating professional suites: use demos from MadMapper, Resolume or HeavyM, then buy the tool you actually need.
- Windows/Linux focused mapping: compare HoloMapper against the larger suites before committing.

Frequently asked questions
Is there completely free projection mapping software?
Yes. MapMap is free and open source, while VPT is freeware. TouchDesigner also has a free Non-Commercial edition, but its license and resolution restrictions matter.
Can I use free projection mapping software for paid work?
It depends on the license. Open-source/freeware tools may allow commercial use, while TouchDesigner Non-Commercial explicitly does not. Always check the current license before a paid show.
Is HoloMapper free?
No. HoloMapper is a paid Early Access product sold as a one-time purchase through Steam. It is included here as a paid alternative, not presented as freeware.
