Reference Tools for Linux Artists: What to Test

Pick the workflow first, then test the Linux build. A package being available does not prove that every window control works the same way on every desktop environment.

Choose a shortlist

PureRef and BeeRef publish Linux downloads. PureRef has license tiers; check which applies to your work. BeeRef is GPL-3.0 software with an embedded scene format.

TagStudio is a tag-focused option whose reviewed project status is alpha. Allusion uses watched folders; check the release or fork you intend to install. Neither an old release nor a programming language establishes how your library will perform.

digiKam is worth checking for photography collections, metadata writing, and image retrieval. It can serve an artist's archive without providing the same board workflow as a reference canvas. For tools that tag and search images on your own computer, including on Linux, see offline AI image organizers.

Test your actual desktop session

Record your distribution, desktop environment, and whether you use a Wayland or X11 session. Open the app alongside your painting or 3D tool and try the controls you rely on: pinning, focus, shortcuts, dragging, and multiple monitors.

refern supports Linux, but its window-opacity and clickthrough controls have Linux limitations. Do not choose it on an assumption of full Windows/macOS overlay parity.

Use the official download instructions for each tool. An unofficial package or compatibility layer may have a different update path. Eagle's official Linux support page does not establish a Linux client; a community workaround is a separate choice.

Check files, not just screenshots

Try images and video formats from a real project. Confirm what receives a native preview and what is only cataloged as a file. refern builds its own flattened previews for Krita (.kra, .krz), OpenRaster, PSD, PSB, Clip Studio Paint, and Procreate files; other types show a system thumbnailer's preview where one is installed, otherwise an icon. Test a board with linked sources after closing and reopening it.

For an existing-folder catalog, note the database and cache location. In-place indexing still creates application data, and explicit moves, imports, deletes, or metadata writes can change files. Keep a backup before testing migration.

Compare only like-for-like performance

Use the same files, machine, and task. Separate initial indexing from browsing after thumbnails exist. Do not treat a large-library bug report from a different release or system as a universal Linux limit.

If you already use PureRef, see PureRef on Linux for that specific starting point. This page covers choosing across library and board categories; the dedicated page addresses PureRef packages and alternatives.
