Why Karpfolio exists

You collect with precision.
Your tracker should too.

Every generic tracker tries to cover 50,000 cards across every TCG ever printed. The result? Shallow data, wrong prices, and your 1st Edition Lugia drowning next to bulk modern pulls.

Every other tracker
  • 10,000+ sets you'll never need
  • One price source, often months behind
  • No sales history — just a number
  • Can't tell 1st Ed from Unlimited
  • No PSA population. No market cap.
  • Your vintage cards are an afterthought
Karpfolio
  • 17 WOTC sets. Nothing else. Zero noise.
  • eBay + top auction houses — live
  • Full sales chart per card, per grade
  • 1st Ed, Holo, Reverse, Shadowless, Box Topper
  • Population & market cap on every card
  • Built by a vintage collector. For vintage collectors.
Our Secret Weapon

The Guide Price: one number
you can actually trust.

Not a static catalog number. Karpfolio's Guide Price is a proprietary weighted score — 6 verified sources, weighted by recency, reliability, and volume. The price your card would realistically sell for today.

Features

have always deserved

FAQ

Quick answers

A portfolio tracker built exclusively for vintage Pokémon cards (WOTC era, 1999–2003). Add your PSA graded cards and get live market prices aggregated from eBay and leading auction houses — plus analytics, sales history, population data, and more.
Vintage cards need specialized data — edition variants, different market dynamics, and dedicated sales filtering. By covering only WOTC, we deliver pricing accuracy and data depth that generic trackers can't match. We may expand to other vintage or collectible categories, but we'll never add bulk modern sets. Depth over breadth, always.
Real completed sales from eBay (the largest secondary market) and top-tier auction houses. Every price you see is a transaction that actually happened — not an estimate or algorithm output.
Karpfolio is currently optimized for PSA, which dominates vintage Pokémon card sales. BGS/CGC support is on the roadmap and will be added based on collector demand.
30 days of full, unrestricted access. No credit card. No feature limits. Add cards, explore analytics, check prices — everything. After 30 days, pick monthly (€5) or yearly (€50).
Karpfolio is a mobile-first web app — visit karpfolio.app on any device and it works like a native app. A dedicated iOS app is in development.
Magikarp. The most underestimated Pokémon ever printed. It only knows Splash — but give it time, and it becomes Gyarados. Same energy as a vintage card collection: patience, conviction, and a splash of faith.

You know what your cards
are worth to you.
Now know what they're worth to the market.
