Free Projection Mapping Software in 2026: What's Actually Free

There Are Four Kinds of "Free" — and They Are Not Equivalent

Most listicles collapse everything into one bucket, which is why people download three tools in an evening and end up with nothing usable. "Free" here covers four genuinely different arrangements, and knowing which one you are looking at tells you most of what you need to know.

• Free and open source. No cost, no watermark, no expiry, no commercial restriction. You pay in learning curve and in the risk that the project goes quiet. VPT and MapMap live here.
• Free for non-commercial use. Free forever and fully featured, but the licence forbids paid work and usually caps something technical too. TouchDesigner's Non-Commercial licence is the obvious example.
• A free tier of a commercial product. The real app, with real limits attached: a watermark, a gate, or a locked export path. This is where SurfaBeam's free edition sits, and I will be specific about it below.
• A trial wearing a free badge. Resolume and MadMapper are paid products. Their demos exist for evaluation, not for running a show, and anything you project through them announces that fact.

A fifth group deserves naming separately: free apps that are not mapping software at all. VLC plays anything and has no geometry tools. HeavyM Remote is free on both mobile stores, but it is a control surface for a HeavyM desktop session — the mapping happens on the computer, not on the phone. Both are useful; neither will warp video onto a curved column.

Free Options Compared: What Each One Actually Limits

The final column is the one that matters. Everything here will put an image on a wall; what separates them is what they take back.

For a wider look at the mobile side of this market, including tools that are not free, our comparison of the seven best projection mapping apps for iOS and Android covers Optoma Projection Mapper, Lazy Lighting, TouchViZ and the rest.

The Genuinely Free Desktop Tools, Honestly Assessed

VPT — the most capable free option, and the least welcoming

VPT (Video Projection Tools) is free projector mapping software for macOS and Windows, built on the Max runtime by artist HC Gilje. It handles multiple layers, live camera sources, masks and per-surface warping, with no watermark and no restriction on commercial use. On raw capability it does more than most mobile mapping apps, paid ones included.

The cost is the interface. VPT looks like a patched instrument rather than a consumer application: dense panels, abbreviated labels, a mental model you learn rather than guess. Budget a weekend, not an evening.

MapMap — the gentlest free desktop start

MapMap is open source under the GPL and runs on Linux, macOS and Windows. You create a source (an image or a video), create a destination shape on the output, and drag its points until they match the physical object. Quads, triangles and mesh surfaces are all supported. That is more or less the whole app, which is exactly why beginners get somewhere with it.

Development has run in bursts, so check the state of the repository and confirm it still builds cleanly on your OS version before you rely on it. That caveat applies to a lot of free video mapping software, and it is the most common reason a promising tool disappoints.

TouchDesigner Non-Commercial — free forever, with a hard boundary

TouchDesigner's Non-Commercial licence costs nothing and does not expire. You get the real environment — generative visuals, audio reactivity, sensor input, network control — with two firm conditions: output resolution is capped, and paid work is not permitted. It is a superb place to learn and prototype, not a way to avoid paying for a commercial tool.

Free Projection Mapping Apps on Phones and Tablets

The mobile picture is thinner than the desktop one, and a search for a free projection mapping app on Android returns a lot of results that are not mapping tools at all — remote controls for desktop software, media players, and lighting-effect apps that throw a moving pattern with no geometry correction whatsoever. Three questions separate the real ones from the rest, and you can answer all three from the store listing and ten minutes of use.

• Does it warp, or only keystone? Keystone correction moves four corners to square up a trapezoid. Mapping subdivides the image into a grid and lets you drag interior points, which is the only way to follow a curve or an irregular edge. If the screenshots show four corner handles and nothing else, it is a keystone tool with a mapping headline.
• How does the picture reach the projector? This is the question people skip and then lose an evening to. Wired output means a USB-C or Lightning HDMI adapter, and on Android it means your phone actually supports video-out over its USB-C port — plenty of budget handsets do not. Wireless means AirPlay or Chromecast, which works but adds latency you will notice on touch-reactive or beat-synced content, so keep the projector on the same 5 GHz network and expect to rehearse with the lag rather than against it.
• What does the free tier take back? Watermark, gate, or saving — check which before you invest setup time, not after.

One practical footnote that applies to every phone-driven map: while the phone is driving the projector it is a display device for the whole show. Turn off auto-lock, silence notifications so a message banner does not appear four metres wide on someone's wall, and put it on a charger — sustained video-out plus wireless casting drains a battery faster than almost anything else a phone does.

Against that, the free mobile field is small. VLC is genuinely reliable when the projector sits square-on to a flat wall and needs no correction at all. HeavyM Remote installs free on iOS and Android, but the mapping runs on a computer and the phone is the remote. And SurfaBeam's free edition runs the mapping engine on the device itself — which brings us to the part where I declare an interest.

What SurfaBeam's Free Version Gives You — and What It Holds Back

I work on this app, so treat the following as a disclosure rather than a recommendation — exactly what the free edition does and does not do, with nothing softened.

What is included, at no cost: the complete mapping toolset. Corner pinning and mesh warping for curved and irregular surfaces, digital masking, multi-surface mapping, MP4 video and PNG image import, touch-reactive and sound-reactive effects, live hand, body and object tracking, the music and hand visualizers, and the Timeline editor. Output over USB-C or Lightning HDMI, or wirelessly via AirPlay and Chromecast. This is the same engine on Android, iOS, macOS and Windows — not a cut-down demo build.

Worth knowing if you are on a desktop: Windows has three separate routes to the same free build — the .exe installer from our site, the Microsoft Store, or Steam, where the base app is a free download and Pro is a separate one-time DLC rather than a subscription. If you already live in Steam, that route means no recurring charge at all when you do decide to upgrade.

What the free edition costs you: three things, and they are not trivial.

• A watermark on the projected image and on exported video. Not just in the app preview — on the wall, in front of your audience, and in the file you export. This rules out client work and anything you plan to post.
• An entry gate before mapping. You either subscribe or, on Android, watch a rewarded ad to continue. It is a few seconds each session, and it is still an interruption at the exact moment you want to start working.
• No saving or loading of project files. This is the one that hurts most in practice. Build a careful eight-point mesh on a curved column, close the app, and you build it again from scratch tomorrow.

Pro removes the watermark and the entry gate, and unlocks Save, Load and Export — including Map Export to PNG, which gives you your mapped geometry as a layer you can composite against in After Effects. Through the App Store and Google Play it is sold as monthly, quarterly, yearly or one-time lifetime plans. If you want to see every panel and gesture before deciding, the full SurfaBeam user guide walks through the free and Pro workflow screen by screen.

The Hidden Costs of Free Software (All of It, Not Just Ours)

Every free tool bills you in a currency other than money. Knowing which currency is the whole trick.

• Time. The most capable free desktop tools have the steepest interfaces. A weekend learning VPT is a real cost, and for one Halloween window it is a bad trade.
• Rework. A tool that cannot save charges you the full setup again every session. Two hours of calibration you cannot store is worse value than most licences.
• Credibility. A watermark on a client's facade is not cosmetic. It reads as unlicensed software, and it is the kind of detail that costs you the repeat booking.
• Abandonment risk. Free projects go quiet. Confirm the tool still runs on your current OS — an install that worked two years ago is not evidence.
• Hardware, which is free for nobody. Software is the cheap part. As a rough working guide, something in the region of 3,000 lumens copes indoors with the lights down, and outdoors you want considerably more — the real number depends on your throw distance, surface colour and ambient light, so test before you commit.

How to Choose Free Projection Mapping Software for Your Situation

Rather than crown a single best free projection mapping software, match the tool to the job. Five situations cover almost everything.

• A flat wall, projector square-on, one video. You may not need mapping software at all. VLC full-screen plus the projector's own keystone control is often the correct answer, and recognising that saves you an evening.
• A curved, angled or multi-part surface, and you want to work on-site. A phone-based tool wins because you can stand at the surface and adjust with your finger instead of walking back to a laptop. SurfaBeam's free edition does this; accept the watermark while you learn.
• Desktop, macOS or Windows, and you enjoy technical tools. VPT. No watermark, no licence restriction, genuinely powerful.
• Linux, or you want something small and readable. MapMap.
• You are being paid. Rule out anything watermarked or non-commercially licensed on the spot. That leaves VPT, MapMap, or a paid licence — and for most working installers the paid licence wins on time saved alone.

A 20-minute test that tells you whether free is enough

Run this before committing to any tool. It surfaces the limits faster than any feature list.

• Export a 1920×1080 PNG of a plain white grid — 100-pixel squares, one-pixel lines. Grids expose warping errors that video hides.
• Project it onto something deliberately awkward: a cardboard box on its corner, or a cylinder. Flat walls prove nothing.
• Corner-pin first, then subdivide to at least a 4×4 mesh and pull the interior points until the grid lines follow the physical edges. If the tool cannot do this, it is doing keystone correction, not mapping.
• Now close the app and reopen it. Whatever you have to redo is your real recurring cost, every single session.
• Finally, look at the projection from where the audience will stand. Watermarks and edge artefacts that vanish on a 6-inch screen are unmissable at 4 metres.

If you have never run through a first map end to end, our beginner's guide to digital mapping covers corner pinning and grid warping step by step, and the smartphone projection mapping guide covers the phone-and-projector version of the same workflow.

When Free Stops Making Sense

Four signals are worth watching for rather than discovering under deadline. Money changing hands: the moment someone pays you, watermarks and non-commercial licences are off the table. Repetition: map the same venue more than twice and the inability to save has already cost more than a licence. Scale: multi-surface installs with tracking or timed sequences depend on saved states and reliable exports. And deadline pressure, where a tool that fights you is a risk you carry into a live show.

Until one of those applies, free is genuinely fine. Learn on it, prototype on it, decorate your own house with it. For seasonal projects specifically, the holiday projection mapping guide is a good place to start, and the 50+ question projection mapping FAQ answers most of the equipment questions that come up afterwards. More tutorials live on the SurfaBeam blog.

Frequently Asked Questions

Is there genuinely free projection mapping software, or is it all trials?

Both exist. VPT and MapMap are genuinely free desktop tools with no watermark and no time limit. TouchDesigner has a free Non-Commercial licence that is free forever but not licensed for paid work and capped in output resolution. Resolume and MadMapper are paid products with demos or trials rather than free tiers. SurfaBeam sits in a fourth category: a free tier of a commercial app that gives you the full mapping toolset but adds a watermark and withholds project saving.

What is the best free projection mapping software for Android?

The free edition of SurfaBeam is the practical answer, because it runs the full warping, masking, tracking and Timeline toolset directly on the phone and is free to download from Google Play. The trade-offs are real: a watermark appears on the projected image and on exported video, an entry gate appears before you start mapping (subscribe, or watch a rewarded ad on Android), and project files cannot be saved or reloaded until you upgrade to Pro. HeavyM Remote is also free on Android but only remote-controls a HeavyM desktop session running on a computer, and VLC is free but does no mapping geometry.

Does the free version of SurfaBeam put a watermark on the projection?

Yes. The watermark appears on the projected image itself and on any exported video, not just in the app preview. That is fine for learning, rehearsing and testing a surface, and it is a problem for paid client work or anything you intend to publish. Pro removes the watermark along with the entry gate, and unlocks Save, Load and Export including Map Export to PNG for After Effects.

Can I use free projection mapping software for paid client work?

Only some of it. VPT and MapMap are free and carry no commercial restriction, so they are legitimate choices for paid jobs if you can live with their interfaces. TouchDesigner's free Non-Commercial licence explicitly excludes commercial use. Demo builds of paid software watermark the output, which is not acceptable on a client wall. A free tier with a watermark, such as SurfaBeam Free, is best treated as an evaluation and rehearsal tool rather than a delivery tool.

Why does free projection mapping software so often block saving projects?

Saving is the feature that turns a one-off experiment into repeatable work, so it is the most common thing a free tier holds back. In SurfaBeam's free version, saving and loading project files is reserved for Pro, which means a map you build has to be rebuilt if you close the app. For a single evening that is a minor annoyance. For a venue you return to weekly, or a multi-surface install you calibrate over two days, it is the limitation that ends up costing you the most time.

Start free, upgrade only when the limits start costing you

SurfaBeam's free edition runs the full mapping engine on Android, iOS, macOS and Windows — warping, masking, tracking, visualizers and the Timeline included. Output carries a watermark and projects cannot be saved until you move to Pro. Try it on a real surface first and decide from there.
