Which operating systems does Milton support?

Milton officially runs on Windows 7 and newer, can be compiled and run on Linux, and does not yet have a finished macOS release — a for-profit macOS version is described as in progress. So if you are on Windows 7+, you can download and run it directly; on Linux you should expect to build it yourself; on macOS there is no supported build to install today.

Platform support at a glance

Windows: the straightforward case

Milton is described as an open-source infinite canvas paint application for Windows, Mac, and Linux, and the download page states support for Windows 7 and up. If your machine is on Windows 7 or a later version, this is the platform with the least friction: download, run, and start drawing.

The app is free and open-source, so there is no purchase step for the Windows build. Note that the site's copyright line reads 2015–2019, which tells you the project's public materials date from that period — worth keeping in mind if you are installing on a very recent Windows release.

Linux: supported, but build it yourself

The site says Milton "compiles on Linux," which is a different promise from "ships a Linux installer." In practice that means you should be comfortable with a source build: fetching the code, satisfying its dependencies, and compiling before you can open the canvas. If you want a zero-setup experience, Linux is not the path of least resistance here.

macOS: not available yet

The page is explicit that work is being done on a for-profit macOS version. Two consequences follow:

• There is no finished macOS build described on the site, so you cannot treat macOS as a supported platform today.
• When that version does arrive, it is planned as a paid product — the free open-source status of the Windows build should not be assumed to carry over to macOS.

If you are on a Mac and want to try Milton now, the honest answer is that the site does not offer you a supported route.

What you get once it runs

Platform choice aside, the same feature set applies wherever Milton runs:

• Infinite canvas with infinite detail — it feels raster-based but works with vectors.
• Automatic saving — your work is saved every time you make a change; there is no save button.
• Small files and unlimited undo/redo that persists after you close the app.
• Layers, blur, and lines.
• Export to JPEG or PNG at any resolution your machine supports.

That last point is worth pairing with your platform decision: export size is bounded by what your machine can handle, so the hardware you run Milton on matters as much as the OS.

Choosing your path

• On Windows 7 or later? Use Milton directly — it is the only platform with a clearly supported, ready-to-run story.
• On Linux and comfortable compiling? Milton is viable; budget time for the build.
• On macOS? Wait for the announced macOS version, and expect it to be a paid release rather than the free open-source build.

Milton was created by Sergio Gonzalez; the site's download and help pages are the place to check for the current state of each platform before you commit.
