PureRef Alternatives for Mac: When You Need One

PureRef is still the right choice for most people

Start here, because it will save you a click. If PureRef already works for you, this article is not asking you to leave it. It does one job better than almost anything else: keeping a board of reference images pinned above whatever you are drawing in, so you never have to alt-tab away from the canvas. It is pay-what-you-want for personal use, it runs from the same download on Windows, Mac and Linux, and among illustrators and concept artists it has the kind of reputation that only comes from being genuinely, quietly excellent for well over a decade.

Most people typing "pureref alternatives" into a search bar are not actually frustrated with PureRef itself. They are looking for something that sits next to it, not instead of it: somewhere to keep the images before they end up on the board, once there are too many to hold in memory. That is a different problem, and it deserves a straight answer rather than a listicle pretending PureRef has five equally good replacements. It does not, not for what it actually does.

So when does it actually make sense to look elsewhere?

Three situations are worth a second app. Everyone else should stop reading here and keep using PureRef.

• You want a searchable library, not a single board. PureRef holds whatever you have dragged onto it this session. It has no index of the four thousand images sitting in old project folders, and no way to search inside them.
• You have thousands of references and cannot find the one you are picturing. A board scales to a few hundred images comfortably. Past that, scrolling and hunting starts costing more time than it saves.
• You want the collection to persist and stay organised between projects, rather than be reassembled from folders every time you sit down to draw. PureRef boards are disposable by design: build one, clear it, build the next.

If none of that sounds like you, this is a good place to stop.

BeeRef: the free, open-source alternative

BeeRef is the closest thing to PureRef that costs nothing and hides nothing. It is free, released under the GPL, with its source code sitting in the open on GitHub rather than behind a closed licence. It does the same core job: drag images onto a canvas and arrange them, and BeeRef's own documentation describes an always-on-top mode that lets the window float above your drawing app the same way PureRef's does, plus batch scaling and arranging for when you drop in a folder at once.

If free and open-source matters more to you than a decade of refinement, BeeRef is a genuine alternative, not a token one on a listicle. It is a real, actively developed piece of software doing PureRef's actual job.

Kuadro: free, but is it still maintained on Mac?

Kuadro predates most of this category. It is a free reference viewer for Windows and Mac, licensed for commercial use at no cost, and for a stretch of the 2010s it was a real rival to PureRef among concept artists who wanted several floating image windows rather than one board.

The Mac build is the part to check carefully before relying on it. Kuadro's own release page lists version 0.9.5, reached after what the developer calls a "long hiatus," with support confirmed for "the latest Macs" as of OSX High Sierra, which shipped in 2017. Nothing on the page confirms it runs, or is signed and notarised, on anything newer, Apple Silicon included.

That does not mean it will refuse to open. It means Kuadro is worth trying as an unmaintained tool at your own risk, not adopting as a supported app with a future, and keeping PureRef or BeeRef as the fallback if it misbehaves.

Apple Freeform: the board you already have

Freeform is Apple's own infinite canvas app, built into every Mac running macOS 13 Ventura or later, plus iPhone and iPad. It costs nothing, needs no download, and does a wider job than PureRef: images, sketches, sticky notes, shapes and text all sit on the same board, and it syncs across your Apple devices through iCloud, with edits available offline and syncing again once you reconnect.

What it does not do is stay above your other windows. Freeform is a document you switch to, like any other app, not a floating layer over your canvas. It also has nothing resembling a search index for images: a board is a board, browsable but not searchable by what is inside it. For someone who wants to combine a few reference images with written notes and does not mind switching windows to see them, Freeform is a genuinely useful, zero-cost option already sitting on your Mac. For the always-on-top habit PureRef trains into people, it is not a substitute.

Muse: the library the wall gets filled from

Muse is the app I build, and it is worth being direct about where it does and does not fit here. Muse has no always-on-top mode. It will not float above Photoshop, Procreate or Blender while you draw, and if that is what you came here for, PureRef or BeeRef are the answer, not Muse.

What Muse does instead is the job none of the reference-wall apps attempt: it is a searchable library for everything you have collected, kept on your own Mac rather than assembled fresh each session. It reads the words printed inside an image, so a screenshot of a colour palette is findable by typing part of what it says. It reads colour, for the dark green thing you cannot name. And with the optional Pro AI pack, it matches on meaning, so a search like "moody interior with warm light" can return pictures nobody ever labelled that way. None of that happens on a board, because a board is a workspace, not an index.

The two pair naturally rather than compete. Save and tag references into Muse as you find them, over weeks or months, then pull the handful you need for a specific piece into PureRef, BeeRef or Freeform when you actually sit down to draw.

Muse gives you 30 days with everything unlocked and no card required, which is enough time to tell whether a searchable library actually changes how you work, or whether a board was doing everything you needed all along.
