Best Chrome Extensions for E-commerce Sellers

Running an e-commerce business means spending hours in the browser every day — researching products, analyzing competitors, managing listings, and tracking inventory. The best Chrome extensions for e-commerce sellers automate the tedious parts and surface the insights you need to make better decisions faster. Here are the top tools for Amazon sellers, Shopify merchants, and general online retailers.

Amazon Sellers

Jungle Scout — Product Research

Jungle Scout is the industry-standard product research tool for Amazon FBA sellers. The Chrome extension shows estimated monthly sales, revenue, and FBA fees for any Amazon product directly on the listing page. It calculates a product's "Opportunity Score" based on demand and competition, helping you identify profitable niches before investing in inventory. The extension data is sourced from Jungle Scout's proprietary sales estimation algorithm, which is widely considered among the most accurate in the market.

Helium 10 — All-in-One Amazon Tool

Helium 10 is a comprehensive Amazon seller platform with a Chrome extension that brings key tools to the Amazon product page. The "X-Ray" feature shows estimated sales data, revenue, and keyword performance for any product. The ASIN grabber extracts product ASINs in bulk, and the profitability calculator estimates FBA margins instantly. Helium 10's free tier provides limited daily use of most tools; paid plans unlock full access.

AMZScout

AMZScout is a lighter alternative to Jungle Scout and Helium 10, with a lower price point and a simpler interface that newer sellers find less overwhelming. Its product analysis includes estimated monthly sales, revenue, competition level, and trend data. A niche finder feature suggests profitable product categories based on your criteria.

Shopify Sellers

Koala Inspector — Spy on Shopify Stores

Koala Inspector analyzes any Shopify store and reveals the apps it uses, its top-selling products, estimated traffic levels, pricing strategies, and ad campaigns. For Shopify merchants researching competitors or looking for product ideas, Koala Inspector is invaluable. It can detect the entire technology stack of a competitor's store — their email marketing platform, review app, loyalty program, and more.

SimilarWeb — Traffic Analytics

SimilarWeb's Chrome extension shows estimated traffic data for any website, including traffic volume, engagement metrics, top traffic sources, and audience demographics. E-commerce sellers use it to gauge competitor size and traffic quality, identify high-traffic sites for potential advertising partnerships, and validate market demand for niche product categories.

General E-commerce Tools

Grammarly — Professional Product Listings

Grammarly catches errors in product descriptions, email campaigns, and customer support responses. Poor spelling in product listings undermines buyer confidence. Grammarly ensures that every piece of customer-facing text on your e-commerce operation is error-free and professional.

Honey — Find Supplier Discounts

E-commerce sellers buy supplies, packaging, software, and services constantly. Honey finds coupon codes for all of these purchases automatically. Over the course of a year, the savings on B2B software subscriptions, packaging suppliers, and advertising platform credits can add up to meaningful margin improvement.

Loom — Product Demo Videos

Loom makes it easy to create quick product demonstration videos directly from your browser. Show a product in use, walk through your Shopify dashboard for a training video, or explain a complex product feature to a wholesale buyer — Loom creates shareable links instantly without any post-production work.

ColorZilla — Maintain Brand Consistency

E-commerce brands need consistent color palettes across product photos, website design, email templates, and advertising materials. ColorZilla's eyedropper captures the exact hex code of any color from any source, ensuring that your brand colors stay consistent across every touchpoint.

Conclusion

Amazon sellers should prioritize Jungle Scout or Helium 10 for product research. Shopify merchants benefit most from Koala Inspector for competitive intelligence and SimilarWeb for traffic analysis. All e-commerce sellers should have Grammarly running to maintain professional communication standards. Explore more tools for commerce and productivity in the Unscart directory.
