A Pokémon TCG collection tracker that runs entirely in the browser: no backend, no build step, no dependencies. Search a card by name or by its printed number, add the printings you own to one or more named collections, and track current market prices, 30-day movement, and total collection value in the currency of your choice.
Live demo → https://arthurfachel.github.io/pokevault/
- Live card search via TCGdex (up to date with new sets, no API key), with pokemontcg.io as a legacy fallback
- Search by printed number (e.g.
113/084orTG13/TG30): matches every set with that printed total so you pick the right one - Current market price per variant (Holofoil, Reverse Holo, …): TCGplayer (USD), falling back to Cardmarket (EUR)
- 30-day price movement with a ▲/▼ badge and a per-card trend sparkline
- Multiple named collections (profiles): create, rename, delete, and switch between them
- Selectable display currency for the collection total: native, USD, EUR, BRL, or JPY
- Local persistence: collections save automatically in the browser; Export/Import produces a portable JSON backup
- Sorting by value, biggest 30-day mover, name, or recently added
- Demo mode with sample data for offline/sandboxed environments
| Current price | TCGplayer market price per variant (USD); falls back to Cardmarket trend (EUR). Both ship embedded in TCGdex card responses. |
| 30-day change | Estimated from Cardmarket's avg1 vs avg30 sale averages (holo-aware), since TCGplayer exposes no price history. |
| Sparkline | Plots Cardmarket's avg30 → avg7 → avg1 → trend points per card. |
| Number lookup | 113/084 → matches sets whose printed total is 84, then fetches card 113 from each candidate set. |
| Display currency | Converts the collection total and 30-day change using daily rates from the ExchangeRate-API open endpoint, with Frankfurter (ECB) as a fallback. |
| Persistence | Browser localStorage by default; falls back to in-memory storage if unavailable. Export/Import moves data as a plain JSON file. |
Single self-contained index.html: vanilla HTML, CSS, and JavaScript. No framework, no bundler, no package manager. Data comes from TCGdex, pokemontcg.io (fallback), ExchangeRate-API, and Frankfurter (fallback).

This started as a personal project, but issues and pull requests are welcome: bug reports, new currencies, additional data sources, or UI polish.
Prices are indicative market data, not appraisals. Very recent releases may not have pricing until the marketplaces list them. This project is unaffiliated with Nintendo, The Pokémon Company, TCGdex, TCGplayer, or Cardmarket.
