Why CriProx?

CriProx brings the fiddly parts of a playtest-card workflow into one focused desktop app. Import a deck list, choose printings or custom art, and preview the physical layout. Print the finished PDF from a dedicated PDF application, then cut with your saved Design Space project.

🔒 Local-first	Projects, imported artwork, and autosaves stay on your device. No account or hosted backend.
📐 Physical dimensions	Millimeter-based geometry, standard 63 × 88 mm cards, matched PNG/SVG output, and 300–1200 DPI export.
🃏 Flexible artwork	Search cards, browse sets, commander precons, or tokens, choose Scryfall printings or MPC Autofill community art, or use local images.
✨ Optional upscale	Choose high-detail local 4× enhancement for Scryfall card images when preparing a print PDF; ordinary exports use the originals.
✂️ Reusable cuts	Capture a Design Space template once, print CriProx PDFs from a PDF application, and cut with the same saved project.
✅ Compact print workflow	Completed setup and settings collapse into summaries with green checks. Reopen any section whenever you need it.
📐 Manual nine-card cuts	Print a 3×3 PDF with paper-edge guides for a trimmer, or use a matched Basic Cut PNG with a Cricut.
🔁 Fronts and backs	Export manual-refeed or alternating duplex pages; double-sided cards automatically use their matching reverse face.
💾 Local project library	Browse saved projects, keep uploaded artwork beside each project, and edit reusable sheet, print, artwork, and alignment defaults directly in Settings.

Important

CriProx does not create Cricut registration marks, produce native Design Space projects, or control a cutting machine. Design Space supplies the sensor marks and cut job. The manual nine-card profile deliberately bypasses sensor registration and requires repeatable physical mat placement. Read the Cricut workflow and physical validation guide before committing a full deck to card stock.

From card list to cut

1. Build the sheet. Import a Moxfield or Archidekt link, paste a deck list, search cards, browse sets, commander precons, or tokens, or add local artwork.
2. Dial in the output. Choose the machine, paper, layout, resolution, bleed, and optional card backs. Edit your preferred setup directly in Settings and save it for future projects, or also apply it to the current deck.
3. Set up the cut template once. In Create print PDF, download the setup PNG. Upload it to Design Space as a flat Print Then Cut image, preserve the supplied dimensions, and save the project and mat arrangement.
4. Capture the template once. Save that Design Space job's print output as a one-page PDF and import it into CriProx to verify and save its registration marks. The setup sections collapse with green checks; choose Done for reviewed settings, and reopen any section from its header.
5. Print the PDF. Use the visible prepare controls, review the pages, and save the finished card-sheet PDF from CriProx. Open it in a dedicated PDF application and print at 100% / Actual size, with fit or shrink scaling disabled.
6. Cut with the saved project. Reopen the matching Design Space project and mat, choose Already Printed / Skip printing when available, and cut the printed sheet.

Reuse the captured template for later decks with the same cut geometry. Changing paper, spacing, machine, layout, or the saved cut job requires a matching new capture. The workflow guide covers the paper settings and a measured test print and cut before a full deck.

CriProx also exports transparent artwork PNGs, matched vector geometry, dimensions, and a Design Space handoff guide for the separate direct PNG workflow. Those exports do not contain registration marks; use Create print PDF for reusable registered pages.

Export filenames use the deck name, output paper, layout, and purpose, such as My-Deck-US-Letter-6-card-fronts.pdf or My-Deck-US-Letter-6-card-sheet-01-artwork.png. Reusable setup images and captured templates describe the machine and cut geometry, so they can be shared across decks. Manual Cricut PDFs also include readable cut offsets. Existing captured templates with older filenames still load automatically.

For higher sheet density, the experimental manual profile prints nine cards on Letter or A4 and downloads a matched 191 × 266 mm Basic Cut PNG. It is a physical alignment workflow, not Print Then Cut, so validate the page and mat position on plain paper first.

Selecting Manual cutting as the machine also uses the nine-card layout. The sheet editor previews configurable card and page cut guides as you change their separate colors, width, placement, line style, corners, length, and page style. The front PDF uses those guides; backs remain artwork-only. Cricut registered layouts show their saved Design Space registration marks and exported card positions in the sheet preview. Until a matching capture is saved, the preview uses approximate marks. Print at actual size and check the dimensions before cutting.

Download

Installers for the latest stable release are available on the GitHub Releases page.

Platform	Package	Notes
macOS	Universal DMG	Apple Silicon and Intel; currently unsigned
Windows	x64 NSIS installer	Currently unsigned
Linux	x64 AppImage	Creates exports; Cricut Design Space is not available on Linux

Install on macOS

1. Download the Universal DMG from the latest release.

2. Open the DMG and drag CriProx into Applications.

3. Because CriProx is not yet signed or notarized, macOS may block the first launch. Only for a copy downloaded from the official repository, open Terminal and run:

   xattr -dr com.apple.quarantine "/Applications/CriProx.app"

4. Open CriProx from Applications.

Install on Windows

1. Download the x64 .exe installer from the latest release.
2. Run the installer. Because CriProx is not yet code-signed, Microsoft Defender SmartScreen may display a warning. If the installer came from the official repository, select More info, then Run anyway.
3. Complete the setup wizard, then open CriProx from the Start menu or desktop shortcut.

Update CriProx

CriProx checks GitHub for newer stable releases when the desktop app starts and displays a notice, but it does not install updates automatically.

1. Close CriProx. Export a JSON backup first if you want an additional copy of an important project.
2. Download the package for your operating system from the notice or the latest release.
3. On macOS, open the new DMG, drag CriProx into Applications, and choose Replace. Run the quarantine command above again if macOS blocks the new version.
4. On Windows, run the new .exe installer and complete the setup wizard.
5. Reopen CriProx. Application updates do not replace the managed project library, which is stored in the app's Application Support folder by default or in the folder selected in Settings. When upgrading from v0.6.0 or earlier on macOS, use Settings → Project library → Import old library once to copy projects from Documents/CriProx without changing the new default.

New releases include a SHA256SUMS.txt file for installer verification. See the installation guide for Linux notes, troubleshooting, and local-development setup.

Quick start for contributors

CriProx requires Node.js 22 or newer and npm.

git clone https://github.com/Go2Engle/CriProx.git
cd CriProx
npm ci
npm run dev

Open http://127.0.0.1:5173, or run npm run desktop to build and launch the Electron app.

npm test          # Run geometry, parsing, rendering, and validation tests
npm run build     # Type-check and build the production renderer
npm run package   # Build an installer for the current operating system

Project status

CriProx is a software-tested prototype. Its layout, export, density metadata, project validation, and registered-PDF recognition are covered by automated and manual checks. Real-world sensor acquisition, printer scaling, cutter alignment, and repeatability still depend on the exact machine, calibration, printer, paper, and mat.

The six-card layout uses an experimental Tabloid setup in Design Space to capture a reusable Letter or A4 template; seven-card supports Letter only. Print the finished CriProx PDFs from a dedicated PDF application and cut with the matching saved Design Space project. The eight-card layout captures a full Tabloid PDF from Design Space and reframes its complete marked area onto the selected US Letter or A4 output paper without scaling, provided it fits with at least 1 mm clearance. The Sheet area selector shows only layouts supported by the selected paper and cutting method. Test one size-check sheet and record physical measurements before printing a full deck. The validation record tracks what is proven in software and what still needs hardware acceptance.
