Best PureRef Alternatives for Artists (2026)

The short answer: PureRef is a great canvas overlay with no search, no tagging, and no cross-project library. If you have outgrown a single board, you need one of the tools below.

By refern. Last updated: June 2026.

PureRef has earned its place in nearly every concept artist's toolkit. It starts in seconds, floats above your painting app, and gets out of the way. Those qualities are real. But PureRef's own handbook confirms it has no tagging, no search, and no way to find a specific image across boards once your collection grows. [pureref.com/handbook/features/]

That is the moment most artists start looking for alternatives.

This guide covers five honest options: what each one does well, where it falls short, and who it is actually for. refern is one of them, listed with the same candor as the rest.

At a glance

What to look for in a PureRef alternative

Before comparing tools, it helps to know which gaps you are actually trying to close.

1. Search and tagging. PureRef has neither. If you cannot find an image without scrolling, you need search. If you cannot filter by subject or project, you need tags.

2. Cross-project library. Every PureRef board is a self-contained .pur file. If you want to reuse references across projects, you need a library that persists independently of individual boards.

3. Always-on-top overlay. This is where PureRef excels. Any alternative should match at least the basic pin-on-top behavior if that is part of your workflow.

4. Platform. PureRef runs on Windows, macOS, and Linux. Eagle does not support Linux. Kuadro is Windows-only in practice.

5. Price model. PureRef is free for personal use. Several alternatives are also free. Others are a one-time purchase or a subscription. Over three years a $10/month subscription costs $360.

1. BeeRef: best free open-source overlay

BeeRef is the closest free alternative to PureRef. It lets you arrange, scale, rotate, and view reference images on a floating canvas while you work in another app, at zero cost and under a GPL-3.0 license. [beeref.org]

BeeRef was created by Rebecca Breu (a Krita contributor) and released in July 2021. It has 760 GitHub stars and approximately 409 Flatpak installs per month on Linux. [github.com/rbreu/beeref, flathub.org/en/apps/org.beeref.BeeRef]

Strengths:

• Completely free, forever. No pay-what-you-want prompt, no upsell.
• GPL-3.0 open source: the file format is a documented SQLite container, not a black box.
• Native Linux builds (Flatpak, AppImage, .deb) as a first-class target.
• Lightweight: the Flatpak is 19 MiB; starts fast and uses minimal RAM.
• Color sampler (click any pixel, copies hex to clipboard).
• Configurable keyboard shortcuts and mouse controls.

Honest limitations:

• No search, no tags, no ratings, no metadata of any kind. Finding an image in a large board means scrolling. [alternativeto.net/software/beeref/about/]
• Each .bee file embeds images fully inside a SQLite container; large collections produce large files.
• macOS support is flagged "experimental" by the developer, who has stated an inability to personally test it. [krita-artists.org]
• Latest release was v0.3.3 in May 2024. A GitHub Discussions thread titled "Is Beeref abandoned/dying?" reflects real community uncertainty. [github.com/rbreu/beeref/discussions]
• No always-on-top transparency or mouse clickthrough (PureRef's click-through feature is absent).
• No GIF or video support. [github.com/rbreu/beeref/issues/52]
• No drag-and-drop from web browsers; only copy/paste works. [alternativeto.net/software/beeref/about/]

Pricing (as of 2026): Free. GPL-3.0.

Use it if: you only need the basic canvas overlay and want zero cost and open-source software. You are on Linux and want a native, well-supported option. You use Krita and want a tool that lives in the same community.

Skip it if: your reference collection spans hundreds of images and you need to find specific ones fast. You need GIFs, video, or animated references. You are on macOS and want a stable experience.

2. Kuadro: best for individual floating windows on Windows

Kuadro is a free Windows tool that opens each reference image as a separate always-on-top floating window, rather than compositing them onto a single canvas. This per-window model suits artists who want a handful of references pinned around their painting app without any moodboard composition. [kruelgames.com/tools/kuadro/]

It was made by Luiz Kruel, a technical artist at Rockstar Games, and first released January 16, 2015. [cgchannel.com, January 2015 coverage]

Strengths:

• Completely free, commercial use included. No pay prompt.
• Mouse clickthrough ("paint through" mode): lock images so mouse events pass to the app below, allowing tracing or eyedropping under the reference. [render.otoy.com forum]
• Portable: runs as a single .exe with no installation, from a USB or cloud drive.
• Multi-monitor native: each image is its own OS window, naturally spanning monitors.
• Adjustable window opacity per image.
• Layout presets saved as .ref files with relative paths, surviving drive changes.

Honest limitations:

• Windows only in practice. The macOS version (v0.9.5) is officially unsupported and users are told to try it at their own risk. No Linux version exists. [luizkruel.gumroad.com/l/kuadro_osx]
• Very low development activity. The last publicly announced release was v0.9.5 in August 2018. An unconfirmed later release exists per one user report from 2022, but no release notes were findable. [alternativeto.net/software/kuadro]
• No library, no organization, no tagging, no search. Users navigate through the OS file manager every session.
• No single canvas or unified moodboard. Images are separate windows; you cannot save a composed layout as one exportable file.
• All-or-nothing locking: you cannot lock some images while keeping others draggable. [animationandvideo.com, 2020 review]
• A documented bug causes images to progressively shrink when cycling through a folder with arrow keys. [animationandvideo.com, 2020 review]

Pricing (as of 2026): Free.

Use it if: you are on Windows, want a handful of floating reference windows with zero setup, and have no need for organization or a canvas.

Skip it if: you are on macOS or Linux. You need any organization or search. You want an actively maintained tool.

3. Eagle: best for pure library management (no canvas)

Eagle is the most established desktop library manager for designers and artists, with deep organization, color search, and support for 99 to 108 file format previews. It does not have a canvas or a reference overlay mode; it is a pure library tool. [eagle.cool]

Eagle is made by a team based in Taipei, Taiwan. It costs $34.95 one-time for 2 devices and includes a 30-day free trial. [en.eagle.cool/store] The price increased from $29.95 in November 2024. [en.eagle.cool/blog/post/price-adjustment-notice-2024]

Strengths:

• Strong library organization: hierarchical folders, tags, smart folders (including nested multi-condition smart folders), color labels, ratings, descriptions, source URLs, batch operations.
• Full-text search plus color search by hex/RGB/HSL, with an adjustable accuracy slider.
• Local visual similarity search via the AI Search plugin, available now from the Plugin Center (released March 2026 for Eagle 4.0, fully offline). [en.eagle.cool/blog/post/eagle-plugin-ai-search]
• Format preview breadth: 99 formats on Windows, 108 on macOS, including fonts, audio, video, 3D (GLB, STL), PDF, and source files (PSD, AI, Sketch). [en.eagle.cool/support/article/what-file-formats-does-eagle-support]
• Font management: preview and categorize fonts without installing them. refern does not have this.
• Plugin ecosystem: hundreds of community plugins for format conversion, AI tools, downloaders, and more. [community-en.eagle.cool/plugins]
• 400,000+ self-reported users, years of YouTube tutorials, and a large third-party community.
• Browser extension for Chrome, Firefox, Safari, Edge, and Brave.

Honest limitations:

• No Linux. Eagle has confirmed it currently only provides Windows and macOS versions. [en.eagle.cool/support/article/is-eagle-client-available-for-linux]
• No canvas or moodboard. Artists who use PureRef for overlay or composition work still need a separate tool.
• Copies all files into a proprietary .library folder on import, effectively doubling disk usage. Eagle's own documentation acknowledges this as a common question. [eagle.cool FAQ]
• No relationship graph view and no entity linking.
• No native cloud sync; users must use Dropbox, Google Drive, or NAS. [en.eagle.cool/support/article/how-can-i-sync-my-eagle-library-across-multiple-devices]
• Base license covers 2 devices vs. refern's 3. Additional devices cost $17.50 each. [en.eagle.cool/upgrade]
• English-language support has received criticism for slow response times on Capterra and Product Hunt, with one reviewer reporting a 17-day wait. [capterra.com/p/184384/Eagle/reviews/]
• Student and educator discount was discontinued May 13, 2026. [en.eagle.cool/support/article/do-i-get-a-discount-if-i-am-a-student]

Pricing (as of 2026): $34.95 one-time, 2 devices.

Use it if: you need the widest possible file format support, font preview and management, or a mature plugin ecosystem. You are on Windows or macOS and want a proven, large-community library tool without a canvas.

Skip it if: you are on Linux. You want a canvas or overlay alongside your library. You do not want your files copied into a proprietary library folder.

4. Milanote: best for cloud collaboration and client sharing

Milanote is a cloud-based visual board tool aimed at creative professionals who share work with teammates or clients. It is strong on collaboration and templates, weak on library management and offline use. [milanote.com]

Milanote was founded in 2016 in Melbourne, Australia, and has 35,000 paying customers with $2.8M ARR as of 2024. [getlatka.com/companies/milanote] It is available on web, iOS, Android, and via PWA/Electron wrappers on macOS and Windows.

Strengths:

• Real-time multi-user editing with visible cursors, commenting, and @mentions. This is a genuine differentiator that refern does not have today.
• Cloud sync: boards are available from any device with an internet connection.
• iOS and Android mobile apps.
• 100+ profession-specific templates (moodboards, storyboards, game design docs, UX flows, and more). [milanote.com/templates]
• Freeform canvas that holds notes, images, links, files, color swatches, checklists, and PDFs.
• Browser extension for Chrome, Firefox, and Safari (rated 4.8/5 on Chrome Web Store). [milanote.com/product/moodboarding]
• Free plan with no time limit (100 total items, 10 file uploads). [milanote.com/plans/]
• Searchable Pexels stock photo library (3 million images) built directly into the tool.

Honest limitations:

• Cloud-only. All data lives on Milanote's servers. No local-first option. Offline editing is very limited; it has been a top feature request for years with no full implementation. [niftypm.com/blog/milanote-alternatives/]
• No image library at scale. Performance degrades noticeably above 300 to 500 cards per board. [checkthat.ai/brands/milanote/pricing] Milanote is not designed for libraries of thousands of images.
• No tagging system. Cards cannot be tagged for cross-board retrieval. [nuclino.com/alternatives/milanote-alternative]
• Basic search only: no operator filtering, no image search, no color search, no duplicate detection.
• No version history. You cannot restore a previous state of a board. [nuclino.com/alternatives/milanote-alternative]
• Subscription required for any serious use: $9.99/month annually ($120/year). Over three years that is $360 vs. a $30 one-time purchase.
• Mobile experience is significantly weaker than desktop; users describe it as a viewing companion rather than a full editor. [producthunt.com, capterra.com reviews]
• macOS and Windows apps are PWA/Electron wrappers, not native apps.

Pricing (as of 2026): Free (100 items, 10 uploads, no time limit); Individual $9.99/month billed annually ($12.50/month billed monthly); Team $49/month billed annually (up to 50 people). [milanote.com/plans/]

Use it if: you share creative boards with clients or teammates regularly, need real-time collaboration, want a mobile app, or prefer not to manage local files.

Skip it if: you are managing a large growing library of reference images, need offline-first reliability, want to avoid a subscription, or need advanced search and tagging.

5. refern: best for canvas plus library in one app

refern is a desktop reference manager for artists that combines Eagle-style organization with a PureRef-style infinite canvas and an Obsidian-style relationship graph. It costs $30 one time, runs on Windows, macOS, and Linux, and does not copy your files.

refern is built for artists who have outgrown PureRef's single-board model and want search, tagging, and library management alongside the canvas overlay they already rely on. [refern.app]

One early user put it plainly: "organization and search like eagle cool, canvas from pureref."

Library: Nested folder tree, hierarchical tags (with tag groups, linked tags, and macros), color labels, ratings, favorites, descriptions, source URLs, creator metadata, smart folders, image grouping (fan cards), and directory metadata presets. EXIF, IPTC, and XMP metadata are read automatically on import.

Canvas: Infinite canvas with layers and groups, freehand drawing, 9 shape primitives, text elements, image filters, non-destructive crop, and group backgrounds. Pin any canvas window on top with adjustable transparency and full mouse clickthrough (the same overlay use case as PureRef).

Search: Full-text FTS5 search across filenames, descriptions, notes, source URLs, creator, and tags. Fourteen-plus inline operators including tag:, rating:>=3, color:, is:duplicate, derived:, and linked:. Color search by hex. Image-to-image visual similarity using a local 512-byte descriptor. All local, no API calls, no internet required.

Relationships: Typed entity links (grouped, derived-from, placed-in-canvas, cross-reference), a Linked References sidebar, and a navigable relationship graph view across the whole library.

Capture: Browser extension for Chrome, Firefox, and Safari with hover-save, right-click save, and batch save. Reads EXIF/IPTC/XMP metadata on import. Import from Eagle (folders, tags, ratings, sources, notes).

Never copies your files. A workspace is a normal folder on disk. refern stores a SQLite index and thumbnails alongside your originals and indexes them in place. No proprietary library folder, no disk doubling.

Honest limitations:

• No cloud sync or collaboration yet. Cloud sync and sharing are planned for Phase 2. refern is single-user and local-first today.
• No mobile or web app (Phase 3 roadmap).
• No plugin ecosystem at launch (planned).
• No font management.
• Younger than Eagle and PureRef; smaller community and fewer tutorials so far.
• No AVIF support yet (planned).
• Local-model auto-tagging is planned but not shipped.
• A 30-day free trial is available; PureRef is free for personal use indefinitely.

Pricing: $30 one-time, launch pricing, going to $35 about two months after launch. 1 license, up to 3 devices, commercial use included. 30-day free trial, no account required.

Use it if: your reference collection spans multiple projects and you want to search and tag across all of it. You want one app instead of PureRef plus an asset manager. You are on Linux. You hate that Eagle copies your files. You want Obsidian-style relational links between your visual assets.

Skip it if: you primarily use PureRef for short-lived per-project boards and clear them after each job. You are a student or early-career artist who cannot spend $30. You need real-time collaboration with a team today. You need font management or Eagle's 100-plus format previews.

Full comparison table

Who should use which tool

Artists who need a free overlay and nothing more: BeeRef on Linux or Windows, Kuadro on Windows. Both cover the basic "float images above my painting app" use case at zero cost.

Artists with large libraries who also use PureRef: refern is the most direct answer. It adds the library, search, and tagging that PureRef cannot provide while keeping the canvas and overlay workflow in one app. See refern vs PureRef for a full comparison.

Artists who want the deepest library management and do not need a canvas: Eagle, if you are on Windows or macOS. Strong organization, the largest format support, and a mature plugin ecosystem.

Teams or freelancers who share boards with clients: Milanote, for cloud collaboration and sharing links that do not require sign-up.

Linux artists who need both a library and a canvas: refern is the only option here. Eagle and Kuadro have no Linux support; Milanote works via the web but is not a native app.
