For Amazon and marketplace sellers
1. Keepa: Price and sales-rank history charts on Amazon product pages. Essential for spotting price trends and deals; the core features are free.
2. Helium 10: An all-in-one research extension for product ideas, sales estimates and keywords. Paid plans; pricing has changed in 2026, so check the current tiers.
3. Jungle Scout: A popular alternative to Helium 10 for product and sales research across Amazon marketplaces.
4. AMZScout: Quick product research and profit estimates, often used by newer sellers.
For Shopify and D2C brands
5. Koala Inspector: Shows which theme and apps a Shopify store uses, plus its product catalog. Great for competitor research.
6. Wappalyzer: Detects the technology behind any website: platform, analytics, payment and marketing tools.
7. GoFullPage: Captures full-page screenshots of competitor pages, landing pages and your own designs for reviews.
8. ColorZilla and WhatFont: Pick colours and identify fonts on any page, handy when briefing designers.
For ads, tracking and analytics
9. Meta Pixel Helper: Checks whether your Meta (Facebook and Instagram) pixel fires correctly on each page. Broken tracking wastes ad budget.
10. Google Tag Assistant: Debugs Google Analytics 4, Google Ads and Tag Manager tags.
11. Ahrefs SEO Toolbar or Detailed SEO Extension: Shows titles, meta descriptions, headings, schema and links for any page in one click.
For productivity and content
12. Grammarly: Catches spelling and grammar mistakes in listings, emails and posts.
13. Loom: Record quick screen videos to explain tasks to your team or agency.
14. Google Translate: Translate supplier messages and international marketplace content quickly.
15. An AI assistant extension: ChatGPT, Gemini and Claude all offer browser features or extensions that can summarise pages and draft replies. Use them on public pages, not on sensitive customer data.
Stay safe with extensions
- Install only from the Chrome Web Store and check the publisher, reviews and number of users.
- Read the permissions. An extension that can "read and change all your data on all websites" can see your seller dashboards.
- Use a separate Chrome profile for seller accounts with only the extensions you trust.
- Remove extensions you no longer use; abandoned extensions are sometimes sold and changed.

Frequently asked questions
Are these Chrome extensions free?
Many have free versions, such as Keepa’s core charts, Meta Pixel Helper, Tag Assistant and Wappalyzer’s basic lookups. Research tools like Helium 10 and Jungle Scout need paid plans for full features.
Do extensions work on Microsoft Edge or Brave?
Most Chrome extensions also work on Chromium browsers like Edge and Brave, installed from the Chrome Web Store.
Can extensions get my seller account banned?
Reputable research extensions only read public data. Avoid tools that automate actions inside Seller Central or promise to manipulate reviews or rankings, which can break marketplace rules.
Which extension should a new seller start with?
Start with Keepa for price history and Meta Pixel Helper or Tag Assistant to check your tracking. Add a paid research tool once you are actively sourcing products.
