Most free scale modelling apps do one thing — a basic paint converter for two brands, or a simple project list. ModelCraft Pro combines everything you actually need at the workbench into a single offline app that lives in your browser and never needs an internet connection.
🎨
Paint Converter
72 colours cross-referenced across 8 brands — Citadel, Vallejo Model Color, Vallejo Air, Tamiya, AK Interactive, Ammo by Mig, Humbrol, and Mr. Color. Search by name or code. Filter by colour family. Expand any entry to see all brand equivalents at once.
💨
Airbrush Calculator
Select your paint type (acrylic, lacquer, or enamel) and task (primer, base coat, zenithal, camo, detail, wash, or varnish). Get exact mix ratios, PSI range, tip size recommendation, thinner type, cleaning method, and a technique note — tailored to your setup.
🔧
Project Tracker
Track multiple builds with 13 defined stages from assembly through to final varnish. Set status (planning, building, painting, finishing, complete, paused), log scale, kit reference, manufacturer, and notes. Visual progress bar per project.
🧪
Mix Lab
Save custom paint recipes with brand, paint name, and ratio per ingredient. Add notes on the result and link to the project it was used on. Search all your recipes instantly. Never spend an hour trying to recreate a mix you forgot to write down.
📦
Paint Inventory
Log your entire collection by brand, name, and code. Set stock levels (full, half, low, empty). Filter by brand or stock level. Automatically generates a shopping list of every paint running low or empty — ready to take to the hobby shop.

Fully Offline
Everything — your projects, mixes, inventory, and all 72 paint entries — is stored locally in your browser. No account. No cloud. No subscription. Works on Windows, Mac, iPad, or anywhere with a modern browser.
ModelCraft Pro is built for serious hobbyists who switch between paint brands, maintain a collection of hundreds of paints, run multiple builds at once, and want to stop googling "Citadel equivalent of Vallejo 70.995" at 11pm. Whether you build WWII armour, aircraft, fantasy figures, or Gunpla — if you airbrush and you collect paints, this replaces a dozen bookmarks.
Like all Nexior Gray products, ModelCraft Pro is a single HTML file. Download it once, open it in any browser, and it works immediately. No installation, no account, no monthly fee.
