Shelf answers the three questions every equipment manager dreads — who has it, where is it, and when is it coming back — using QR-code-first tracking where every asset gets a unique scannable label, every handover is logged with timestamps and e-signed custody agreements, and every scan captures GPS coordinates displayed on a map. Built on React Router 7 with React 19, TypeScript 5, Prisma 6 ORM, and Tailwind CSS 3 with Radix UI components, the platform generates QR codes and barcodes (Code128, Code39, Datamatrix) printable on DYMO, Brother, and Zebra label printers. The custody system records every handover with user details and generates PDF custody agreements with e-signatures for high-value items, while a complete audit trail tracks responsibility from check-out to return. The visual booking calendar prevents double-bookings automatically, supports partial check-outs and returns with segmented lifecycle bars, and handles quantity-tracked consumables alongside individually serialized equipment. Asset Models enable bulk creation of identical items with shared defaults while maintaining individual QR codes and custody histories. Location tracking displays last-scanned GPS coordinates on MapTiler maps. Supabase Auth provides email and SSO authentication, pg-boss handles background job queuing, and Nodemailer delivers SMTP email. The Shelf Companion app on iOS and Android enables field scanning and bookings. Export Asset Inventory, Asset Distribution, and Custody Snapshot reports for compliance. Deploy via Docker with PostgreSQL and Supabase. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL v3.0 licensed.

DumbAssets delivers a deliberately simple physical asset tracker that does exactly one thing well — keeping tabs on everything you own, from server racks down to individual HDDs, with hierarchical component nesting that mirrors real-world organization. The Node.js backend stores all data in JSON files within a single /data directory, making backups trivial with one folder copy while the PWA-enabled frontend provides responsive access from any device with light and dark theme persistence. Assets track model numbers, serial numbers, purchase dates, warranty expiration dates, and custom descriptions while sub-components nest infinitely — attach a Dell R730 to your server rack, then attach individual drives, CPUs, and NICs to that server with separate warranty and maintenance schedules for each. The Apprise notification engine fires configurable alerts for warranty expirations and maintenance events with direct links back to the specific asset in the web interface. Photo uploads attach visual records to any asset, receipt storage keeps purchase documentation alongside the item it covers, and a flexible tagging system enables cross-cutting organization beyond the hierarchy. PIN authentication with brute-force protection secures the interface, while search covers names, models, serials, and descriptions with sorting by warranty status, tags, components, or alphabetical order. Deploy with a single Docker command mapping port 3000 and one data volume.
