As answered by people managing Modular JavaScript and Card Pilot.
Card Pilot's answer:
Card Pilot is built specifically for trading card sellers. It combines scanning, catalog matching, pricing, inventory, labels, showcases, and marketplace listing in one workflow.
Card Pilot's answer:
It saves time by turning messy card intake into priced, organized, list-ready inventory with fewer spreadsheets, manual lookups, and duplicate tools.

Card shops, online card sellers, breakers, and collectors who manage enough inventory that manual tracking becomes painful.
Card Pilot's answer:
We’re early and don’t publicly list customer names yet. Current users are independent card sellers and small card businesses.
Card Pilot's answer:
Card Pilot was built from the real workflow of selling cards: scan the card, identify it, price it, label it, store it, list it, and keep everything synced.
Card Pilot's answer:
Next.js, TypeScript, PostgreSQL, Drizzle ORM, Cloudflare/R2, Stripe, eBay APIs, Shopify APIs, and AI-assisted card recognition.
