InventoryDifferent

InventoryDifferent is the inventory management app built for serious vintage computer collectors. Connect it to your own self-hosted server and get full control over your collection — no subscriptions, no cloud lock-in, your data stays on your hardware. TRACK EVERYTHING THAT MATTERS Log every machine with complete specs: CPU, RAM, storage, graphics, display, OS. Record condition, rarity, and functional status. Add custom fields for anything else that matters to you. FINANCIAL INTELLIGENCE Know exactly what you've invested. Track acquisition cost, estimated value, list price, and sale price per device. See total spent, net position, and estimated value owned — with a cumulative chart over time. BUILD A COMPLETE HISTORY Add timestamped notes, log completed maintenance tasks with costs, and record the last time you powered a machine on. Every device gets a full service record. FIND ANYTHING INSTANTLY Full-text search across every field — name, specs, serial number, notes, tags, and custom values. Filter by category, status, or condition. Sort any way you like. SCAN TO FIND Point your camera at a barcode or QR code to instantly pull up a device. Generate QR asset tags to stick on your machines. ASK YOUR COLLECTION The built-in AI assistant knows your entire inventory. Ask questions like "which of my Macs have a 68040?" or "what's my total investment in PowerBooks?" Supports voice input and spoken responses for hands-free use. SEE THE BIG PICTURE Charts show your collection by status, condition, category, acquisition year, release era, and top manufacturers. A timeline places your devices alongside historical Apple milestones. YOUR DATA, YOUR SERVER InventoryDifferent is self-hosted. You run a Docker container on a NAS, home server, or cloud VM. Your inventory never touches a third-party service. — Requires a self-hosted backend. Setup takes about 5 minutes with Docker — full instructions at https://github.com/wottle/InventoryDifferent2.
