Brickify vs Ludex in 2026: Which scanner fits your collection?

Brickify vs Ludex in 2026: Which scanner fits your collection? Ludex is built for fast eBay listing; Brickify is the only app that scans LEGO, Pokémon, and Magic in one place. Ludex gives card sellers unlimited free scans and a quick path from scan to listing. Brickify gives collectors prices from real recent eBay sales and a portfolio dashboard for the whole collection. This guide breaks down when you'd pick each app, and when you'd use both. Ludex is the better pick for selling: its scan-to-eBay-listing flow is fast and built for volume. If you're working through a bulk lot of sports, Pokémon, or MTG cards you plan to sell, that workflow is genuinely quick and low-friction. It also covers sports cards, which Brickify doesn't touch. You get unlimited free scans on the free tier, though your portfolio caps out at 60 cards and you're limited to 5 eBay listings per month. The app pulls pricing from eBay completed sales, so you're not guessing at market value. Ludex runs on iOS and Android, covers sports cards, Pokémon, and Magic: The Gathering, and claims a 4.7-star rating. Premium runs about $50 per year. Brickify is the only collectibles scanner that covers LEGO alongside Pokémon cards and Magic: The Gathering. You can scan sealed LEGO sets, built sets, minifigures, loose brick piles, and raw or PSA-graded Pokémon cards all in the same app. No switching between tools, no second account. Raw and PSA-graded prices sit side by side for cards, so you can see both markets at a glance. Brickify also built bulk scanning into the core experience. A shelf of sealed sets or a binder page of cards prices in one pass with a running total. That's not a party trick, it's how actual collectors work. Brickify identifies items in under two seconds with a confidence score; Ludex is built for a fast path from scan to eBay listing. Brickify's confidence score sits right on the result, whether it's a brick, a card, or a set, so you know how much to trust the ID. The real difference is the workflow, not the stopwatch. Ludex is tuned for getting a card listed on eBay quickly, and it's genuinely good at that. Brickify's bulk scan prices a shelf, binder page, or pile in one pass with a running total updating as you go. Different jobs, both quick. With Brickify, yes; Ludex's free tier caps your portfolio at 60 cards. That cap works fine if you're flipping inventory. It doesn't work as well if you're holding a mixed collection of LEGO, Pokémon, and Magic and want to know what it's all worth right now. Brickify's portfolio is built for the whole collection: a live dashboard, value over time across 1 day, 1 week, 1 month, and 1 year windows, trends by theme and set, and syncing across devices. Brickify is free to download and scan; Brickify Pro is $9.99 per month or $60 per year. It's also how more than 100,000 collectors track their stuff, including 25+ of the top LEGO and Pokémon YouTubers (MandRproductions, EvanTubeHD, DaniBobStudios, and more), with 4.6 stars and over 2,000 five-star reviews on the App Store. Both apps price from real eBay sales; Brickify adds a live portfolio dashboard with value-over-time charts. Neither app makes you rely on a static price guide. Ludex pulls from eBay completed sales. Brickify prices from live market comps of real recent eBay sales, not static price guides or algorithmic estimates, and shows raw and PSA-graded prices side by side for cards. On portfolios, Ludex's free plan caps at 60 cards, while Brickify's dashboard tracks value over time, breaks out trends by theme and set, and syncs across devices. One honest note on LEGO: if you want the deepest LEGO market analytics and retirement predictions, BrickEconomy is genuinely stronger there. It's a website rather than a scanning app, and its values are algorithmic estimates rather than live per-listing comps, but the data depth is real. Short version: Brickify covers LEGO plus cards with a live portfolio; Ludex is a card scanner tuned for fast eBay listing. | Feature | Brickify | Ludex | | LEGO scanning | Yes (sealed sets, built, minifigs, loose, bulk piles) | No | | Pokémon cards | Yes (raw and PSA side by side) | Yes | | Magic: The Gathering | Yes | Yes | | Sports cards | No | Yes | | Scan speed | Under 2 seconds with a confidence score | Fast scan-to-listing flow | | Bulk scanning | Yes (shelf or binder page in one pass) | Not a stated feature | | Scan-to-eBay listing | No | Yes (5 listings/mo free) | | Free tier | Free to download and scan | Unlimited scans, 60-card portfolio cap | | Paid tier | Pro at $9.99/mo or $60/yr | About $50/yr | | Pricing source | Live comps from real recent eBay sales | eBay completed sales | | Portfolio | Live dashboard, value over time (1D/1W/1M/1Y), trends by theme and set, device sync | 60-card cap on the free plan | | Platform | iOS and Android | iOS and Android | | Rating | 4.6 stars, 2,000+ five-star reviews | 4.7 stars (claimed) | Choose Ludex to sell cards on eBay fast; choose Brickify to track a mixed LEGO, Pokémon, and Magic collection in one app. Choose Ludex if you're a high-volume card seller moving inventory on eBay. Unlimited free scans and a quick path from scan to listing make it a great flipping tool, and it covers sports cards, which Brickify doesn't. The 60-card portfolio cap won't slow you down because you're moving stock, not holding it. Choose Brickify if you're a collector holding LEGO, Pokémon, Magic, or any mix of the three. You get one app for the whole collection, prices from real recent eBay sales, raw and PSA prices side by side for cards, and a portfolio dashboard with value over time and trends by theme and set. You can scan a whole shelf or binder page in one pass, and it's free to download and scan. Both apps make scanning quick. The choice comes down to what you collect and whether you're selling fast or holding long.
