Shelfgen
Shelfgen helps marketplace sellers create complete product image packs from a single product photo. Instead of guessing the right ratios, dimensions, and content rules for each marketplace, sellers can choose a platform such as Amazon, Shopify, Etsy, eBay, TikTok Shop, Meta Ads, or Google Shopping, then generate a ready-to-upload set of listing images.
The tool creates marketplace-specific visuals including clean main images, lifestyle scenes, macro detail crops, dimension callouts, feature infographics, A+ content modules, banners, mobile-safe creatives, and ad-ready image variations. Shelfgen is built for ecommerce operators who need consistent, compliant, conversion-focused product visuals without arranging a new photoshoot for every SKU.
It is especially useful for Amazon sellers, Shopify stores, Etsy shops, agencies, and small ecommerce teams that want to turn basic product photos into polished listing assets faster.

NextFeed
NextFeed is a product feed management platform built for ecommerce teams that cannot afford feed downtime.
Most feed tools export a file and leave you to fix errors after a channel rejects your products. NextFeed works the other way around: it surfaces approval risk before export. Missing GTINs, titles too short for Shopping query coverage, taxonomy mismatches, image problems and channel policy gaps are flagged in a daily briefing with an owner and a recommended fix.
Connect your catalog from Shopify, WooCommerce, Magento 2, BigCommerce, Google Sheets or custom CSV/XML/API. NextFeed applies channel-specific transformations through a plain-language rules engine plus an AI mapping assistant, then dispatches clean feeds to Google Shopping, Meta, TikTok Shop, Amazon, Pinterest, Microsoft Ads, Klaviyo, Walmart, Shopee, eBay and custom exports — with ongoing validation and sync health monitoring.
No developer required. 14-day free trial, no credit card.
