What CardBndr actually does

Three core pillars, built to work together — offline-first, API-driven, and fast.

Inventory Management

The fastest way to catalogue a Magic collection on macOS. Built for real-world workflows, not spreadsheets.

  • One-click Add — click a card row, choose finish, done. No dialogs to dismiss.
  • Bulk XML / CSV Import — migrate from Magic Assistant or any flat CSV in seconds.
  • Manual Price Overrides — lock any card to your own price; persists across syncs.

Live Data Syncing

Card data and prices stay fresh automatically. Multi-source API integrations work together to keep your local SQLite database up to date.

  • Automated Metadata Enrichment — card data, rulings, set symbols, and hi-res artwork always current from the global card database.
  • Smart Sync Architecture — detects API connection instability and pauses 60s before resuming, ensuring data integrity.
  • Multi-Source Market Valuation — live EUR buy/sell prices per card, per finish, stored locally.

Collection Analytics

Understand your collection at a glance. Colour-coded progress, high-value gap detection, and accurate cost forecasting sourced from live market data.

  • Heat-map completion bars — red → yellow → green → purple as you fill each set.
  • Cost to Finish — live EUR estimate of what the missing cards in any set would cost today.
  • White Whale 🔥 indicator — flags sets that contain a missing card valued above €50.

About Crooked Parrot

Crooked Parrot logo

Crooked Parrot is a tiny indie studio obsessed with building tools that don't suck. CardBndr is our love letter to Magic players who deserve better than bloated, ad-riddled collection apps.

We built CardBndr because we actually use it. Every feature exists because we needed it. The philosophy is dead simple: own your data.

Every decision prioritizes local-first architecture, zero vendor lock-in, and respect for the APIs we depend on. No telemetry. No tracking. No ads. Just a fast, reliable desktop app built by people who get it.

We're committed to keeping CardBndr independent, transparent, and true to what makes it special.
