About CastAddicts
The ultimate platform for die-cast toy car collectors — manage your collection, discover rarity, and buy or sell with other enthusiasts.
What is CastAddicts?
CastAddicts is a dedicated platform for die-cast toy car collectors. Whether you collect Hot Wheels, Matchbox, Tomica, Majorette, Greenlight, or any other brand, CastAddicts gives you a powerful and beautiful home for your collection.
We built CastAddicts because serious collectors deserve more than a spreadsheet. Tracking dozens — or hundreds — of cars across brands, series, conditions, and values is complex. CastAddicts makes it effortless, combining a smart collection manager with a live marketplace, all in one app.
Available on the web and as a native iOS app, CastAddicts is designed to be used on the go — at a toy fair, a car boot sale, or sitting at home cataloguing your latest haul.
Everything You Need as a Collector
Photo-First Collection Management
Add multiple photos to every car in your collection. Our AI can even identify the car from a photo — just snap it and let CastAddicts fill in the details automatically.
Track Your Investment
Record what you paid for each car and set its current estimated value. CastAddicts tracks your total collection worth, total invested, and your overall profit or loss — all in real time.
Multi-Currency Support
Whether you're in the UK, US, Europe, Japan, or Australia, CastAddicts displays prices in your preferred currency using live exchange rates. Your collection, your currency.
Powerful Search & Filters
Find any car in your collection instantly. Search by model name, manufacturer, series, year, barcode, location number, or notes. Filter by condition, status, or sort by value.
Built-In Marketplace
List cars directly from your collection for sale to other collectors on the platform. No third-party fees, no complicated listings — just toggle 'For Sale', set your price, and you're live.
Order Management
When you make a sale, CastAddicts handles the order flow end-to-end. Add tracking numbers, mark orders as shipped, and buyers can confirm delivery — all within the app.
Verified Sellers
Build trust with a verified seller badge on your profile. Buyers can browse seller profiles, see their full listings, ratings, and sales history before making a purchase.
Rarity Insights
CastAddicts compares your car against the entire platform's catalogue to give each model a rarity score. Know which cars in your collection are truly hard to find.
Market Value Data
See average, minimum, and maximum prices that other collectors are listing the same car for. Make informed decisions when buying or pricing your own cars for sale.
Built by Collectors, for Collectors
CastAddicts was designed with the real collector in mind — from casual Hot Wheels fans to serious Matchbox and Tomica enthusiasts. Every feature exists to make collecting more enjoyable.
Why Collectors Love CastAddicts
✓ One place for everything
Stop juggling spreadsheets, Instagram posts, and eBay listings. Your collection, your valuations, and your sales all live in one place.
✓ Know what your collection is really worth
CastAddicts automatically compiles market pricing data from across the platform, so you always know the real-world value of your cars — not just what you paid.
✓ Sell directly to other collectors
Cut out the middleman. The built-in marketplace connects you with buyers who actually care about die-cast cars, just like you.
✓ Storage location tracking
Assign location numbers to cars so you can find them instantly in your storage — no more digging through boxes.
✓ Condition & provenance tracking
Record whether each car is mint in package, loose, or somewhere in between. Keep notes on where you got it, what you paid, and anything else worth remembering.
✓ Works on your phone
The iOS app is optimised for mobile use. Take it to toy fairs, markets, and swap meets to log new additions on the spot or check if a car is already in your collection before you buy.
