I built a free macOS app to automate cross-listing from 1688.com to eBay, Etsy, Amazon and AliExpress

The problem

Cross-border e-commerce sellers who source from 1688.com (China's B2B wholesale platform) and list on eBay, Etsy, Amazon, and AliExpress spend hours on manual work: translating product titles, filtering out branded items, checking images for watermarks, and uploading to each platform one by one.

I was doing this myself and decided to build AutoStore to automate it.

What it does

AutoStore is a free macOS app + Chrome extension that runs the full pipeline:

1. Discovers products on 1688 across 450+ blue-ocean categories
2. Brand filter — 548-brand blacklist scans titles/descriptions/specs to avoid IP violations
3. OCR image check — Vision framework detects watermarks and Chinese text in product photos
4. On-device AI translation — bundled LLM translates titles and descriptions (no API key, no cost)
5. Bulk upload — drives your already-logged-in Chrome sessions on each platform via extension

Technical approach

The key insight: instead of trying to automate platform logins (which triggers bot detection), we drive the seller's existing authenticated browser session through a Chrome extension. The platform sees a normal human user, not a bot.

All data is stored locally — MySQL for products, macOS Keychain for credentials. No cloud dependency, PIPL compliant.

Stack

• Mac app: SwiftUI, Vision framework (OCR), URLSession
• Chrome extension: Playwright-based automation injected into seller dashboards
• Local LLM: bundled llama.cpp server for on-device translation
• Database: MySQL (local)
