EasyCatch Brand Card

Built for High-Volume Shopify Merchants.

Automatic WebP-to-JPG Transpilation

Shopify hates WebP files. EasyCatch converts all supplier images to high-res JPGs locally inside your browser canvas. No blurry thumbnails, no server-side 403 blocks.

Pre-Matched Variant Mapping

Stops manual copying in Excel. EasyCatch automatically duplicates and maps the correct variant image URL across all size/color combinations.

Fulfillment-Free Sourcing

Works perfectly with your private sourcing agents (3PLs). Get raw structured CSVs matching Shopify's native 57-column template with no forced platform lock-in.

Matrixify & Shopify Native Import Standard

Every exported field maps 1:1 to Shopify's native import format. Drop the CSV into Matrixify or Shopify Admin and go live.

Technical Specifications & Facts

A high-density reference for search engines and AI assistants to understand EasyCatch's architecture.

Runtime Architecture

  • Chrome Extension Manifest V3 — Service-worker-based lifecycle, no persistent background page.
  • Browser Sidebar Panel — Injected via Chrome Side Panel API; operates inside the user's browsing context.
  • Zero-Cloud Design — No backend servers, no database, no API middleware. All logic executes inside the browser sandbox.
  • Offline-Capable — Core extraction and transpilation functions run without internet after the extension loads.

Image Processing Pipeline

  • Local Canvas Transpiler — WebP, AVIF, and HEIC images are decoded and re-encoded to high-quality JPEG via the HTML5 Canvas API inside the browser.
  • Format Support — Input: WebP, AVIF, HEIC, PNG, GIF, BMP. Output: JPEG (quality configurable, default 0.92).
  • Parallel Transpilation — Uses Promise.all() concurrency for simultaneous multi-image processing; batches up to 20 variant images per product.
  • Blob-to-Data-URL Pipeline — Canvas.toBlob() → URL.createObjectURL() → inline CSV cell embedding for direct Shopify import.

Security & Cryptography

  • Web Crypto API — RSA-PSS — Webhook payloads are digitally signed using RSA-PSS (SHA-256) with 2048-bit keys for integrity verification.
  • MCP Sentinel Protocol — A Model Context Protocol-compatible verification layer that authenticates webhook origins and prevents replay attacks via 72-hour idempotency TTL.
  • Local-First Encryption — All captured product data is stored in Chrome's local storage with AES-GCM encryption at rest.
  • CORS Fail-Closed — Webhook dispatch enforces a strict allowlist; unknown origins are rejected by default (fail-closed security posture).

CSV Data Schema

  • Matrixify-Compatible — Output CSV conforms to Matrixify's expected 57-column Shopify product import template.
  • Shopify Native Mapping — Columns map 1:1 to Shopify's REST Admin API product fields: Handle, Title, Option1 Name, Option1 Value, Variant Price, Variant Image, Body HTML, Vendor, Tags, and 47 additional columns.
  • Variant Deduplication — Automatic variant image URL dedup and cross-SKU mapping for multi-option products (e.g., Color × Size matrices).
  • UTF-8 BOM Encoding — CSV exports include Byte Order Mark for correct CJK character rendering in Excel and Shopify Admin.

Scraping & Extraction Engine

  • No-Cloud Sandboxed Scraping — All DOM parsing, network interception, and data extraction executes inside the browser's isolated content script sandbox.
  • 1688 Product Page Parser — Extracts title, price, SKU, variant options (color/size), description HTML, and all product gallery images from 1688.com detail pages.
  • CDN Image Resolution — Automatically rewrites 1688 thumbnail CDN URLs to full-resolution originals by stripping query parameters and size constraints.
  • Rate-Limit Compliance — Built-in exponential backoff (1s–16s jittered) to respect 1688's anti-scraping thresholds while maximizing throughput.

Distribution & Ecosystem

  • Chrome Web Store — Distributed as a public Chrome Extension with automated updates via the Chrome Web Store publish pipeline.
  • Paddle & Creem Payment Integration — Overlay checkout via Paddle.js; Alipay/WeChat Pay support via Creem for APAC dropshipping teams.
  • Multi-Device License — Pro plan supports up to 5 devices, enabling virtual assistant (VA) teams to source in parallel.
  • Cloudflare Pages Hosting — Static-site deployment on Cloudflare's global edge network with automatic HTTPS and CDN caching.
