Best Chrome Extensions for Amazon Sellers in 2026

Quick Answer: The Best Amazon Seller Extensions Right Now

The best Chrome extensions for Amazon sellers put profit, sales rank, price history, restrictions and keyword data directly on the Amazon product page, so you can decide in seconds whether a product is worth sourcing. For online and retail arbitrage, the core stack is usually Keepa (price and rank history) plus one profit calculator such as SellerAmp SAS, Seller Assistant or RevSeller. Private label sellers lean more on research extensions like Jungle Scout, Helium 10 and AMZScout.

Below is a quick comparison, followed by a closer look at each Amazon seller extension, what it does well, and what it costs today. Prices change often, so always confirm on the tool’s official pricing page before you subscribe.

Here are the Chrome extensions Amazon sellers use most, with current features and pricing:

Jungle Scout Chrome Extension

Jungle Scout is one of the most popular Amazon seller Chrome extensions for product research. It works alongside the Jungle Scout web app and shows estimated sales, revenue and rank right on Amazon search and product pages. The extension is included in all of Jungle Scout’s Catalyst plans, which start at $49/month (or $29/month billed annually), and it fully supports eight marketplaces: the US, Canada, Mexico, the UK, France, Germany, Italy and Spain.

With the Jungle Scout extension you get:

• Estimated monthly sales and revenue
• Best Sellers Rank and price trends
• Amazon keyword research
• Listing quality and competition data

RevSeller Extension

RevSeller is a long-time favorite of arbitrage sellers. It opens a compact panel on every Amazon product page with fees, profit and ROI, so you can make a quick buy or skip decision. It also includes a variation viewer, restriction checks and an export to Google Sheets, and it works on Amazon.com and Amazon.ca. Read our RevSeller review for a full walkthrough.

Its built-in FBA and FBM calculator breaks down:

• Price
• Referral fees
• Shipping costs
• Profit margin
• ROI

RevSeller also shows sales rank, product dimensions, UPC and ASIN. Pricing is $19.99/month or $99.99/year, with a 30-day free trial.

AMZScout PRO AI Extension

AMZScout‘s extension, now called PRO AI, speeds up product research on Amazon search results. It estimates sales and revenue, calculates FBA fees and gives each product a score, and it covers 14 Amazon marketplaces. See our AMZScout review for the full breakdown.

For each product idea, AMZScout shows:

• Demand forecasts
• Profit estimates
• Stock levels
• Competitor analysis

The PRO AI extension costs $45.99/month or $269.99/year (a lifetime option is also offered), with a free trial and a 10-day money-back guarantee.

SellerApp Chrome Extension

SellerApp offers a web app and a Chrome extension for live product and keyword research while you browse Amazon. The extension is free with a free SellerApp account; paid plans start at $99/month for more data and features. Our SellerApp review covers the plans in detail.

Useful features include:

• Listing quantity alerts
• Listing quality scores
• Pricing and keyword tracking
• FBA fee estimates
• Buy Box statistics

Helium 10 Chrome Extension

The Helium 10 Chrome extension (with its Xray tool) shows estimated sales, revenue, keyword data and competitor stock levels directly on Amazon. It is free to install, but the free plan only allows limited use; full Xray access requires the Platinum plan ($129/month, or $99/month billed annually) or higher.

This all-in-one extension is capable of:

• Analyzing demand
• Finding suppliers for ASINs
• Calculating profitability

Keepa Chrome Extension

Keepa is the most widely used Amazon price tracker, with millions of users on the Chrome Web Store. It adds a history chart under every Amazon listing, which is essential for judging whether a deal is real and how fast a product sells. It shows:

• Amazon, Buy Box and third-party price history
• Sales rank history and estimated sales
• Offer counts and stock data

Keepa can also alert you when a price drops. Basic charts are free; the detailed data most arbitrage sellers rely on (sales rank, offer counts, Buy Box history) needs a paid Data Access subscription, so check Keepa’s site for the current price.

Camelizer Chrome Extension

The Camelizer is camelcamelcamel’s free browser extension. It shows a product’s Amazon price history and lets you set price-drop alerts, which is handy for tracking:

• Price fluctuation of their competitors
• Extensive history for listing price data

It is free, but it offers far less seller data than Keepa (no sales rank or offer history), and the extension has not been updated in a while. Read our camelcamelcamel review to see how it compares.

AMZ Base Extension for Quick Product Lookups

AMZ Base is a free extension for quick product lookups. It grabs a listing’s ASIN and title and lets you search the same product on other marketplaces in one click.

It can also cross-reference products on Amazon and eBay. Its main features are:

• Product sourcing information
• ASIN number display
• FBA calculator

It is basic compared with paid sourcing tools, but useful for fast manual checks.

DS Amazon Quick View Extension for Competitor Analysis

The DS Amazon Quick View extension adds key data to Amazon search results, so you can compare products without opening each listing:

• Number of FBA sellers
• ASIN
• Best Sellers Rank (BSR)
• Search ranking

The basic version is free. The Extended version is a one-time paid license that adds better sorting and filtering and interactive Keepa graphs.

AmazeOwl Chrome Extension for FBA Research

AmazeOwl was built for private label product research without leaving Amazon. Development appears to have stalled, though, and its sign-up and pricing pages have not been reliable, so make sure the extension still works for you before building a workflow around it.

Its main features were:

• Hover information
• Easy-to-understand color coding
• One-click functionality

A “Market Analysis” button generates a table that highlights products matching your criteria.

Viral Launch Chrome Extension

The Viral Launch extension comes with its Market Intelligence product and is aimed at private label sellers who want in-depth market data on a niche. It shows:

• Past sales
• Pricing history
• Revenue data
• Market trends for a niche

PayPal Honey (Coupons, Not Seller Data)

PayPal Honey is not a seller tool; it is a coupon extension that tests promo codes at checkout, which some arbitrage sellers use to lower their buy cost. Be aware that Honey has faced heavy criticism and lawsuits since late 2024 over how it handles affiliate links, and Google tightened Chrome Web Store rules for coupon extensions in 2025. For sourcing, a cashback website for online arbitrage is usually the more reliable way to cut costs. Honey checks:

• All promo codes
• Available coupons

Amazon Keyword Extensions (FBA Keyword Tool and Search Suggestion Expanders)

Buyers find products on Amazon through search, so keyword extensions are popular with sellers who create or optimize listings. Note that the “Amazon FBA Keyword Tool” extension is a third-party tool, not an official Amazon product, and its Chrome Web Store listing no longer loads. Search suggestion expanders, which pull extra Amazon autocomplete suggestions for a seed keyword, are still a quick free way to brainstorm keywords.

With a keyword extension you can:

• Find relevant long-tail keywords
• Get rough search-volume estimates (for reliable volumes, use Helium 10 or Jungle Scout)

Unicorn Smasher

Unicorn Smasher was a popular free all-in-one research extension from AMZTracker. The original extension has not been updated since September 2024 and has low ratings, so treat it as a legacy tool. Be careful with look-alike “Pro” listings from other publishers. Its dashboard showed:

• Sales rank
• Reviews
• Competitors’ prices
• Ratings
• Projected sales velocities

If you would rather not hunt for products yourself, buying online arbitrage leads is a hassle-free way to get pre-checked products to source.

AMZ Seller Browser Extension

AMZ Seller Browser is a free product research extension that many sellers still search for. It is still listed on the Chrome Web Store, but it has not been updated since 2022, so expect some features to be outdated.

Its main data points are:

• Price history
• Keyword ranking

SellerAmp SAS and Seller Assistant: Best Extensions for Online Arbitrage

If you resell products from other retailers, the two extensions most arbitrage sellers compare are SellerAmp SAS and Seller Assistant. Both show profit, ROI, BSR, eligibility, restriction warnings and a Keepa-style chart in one panel while you browse retailer sites or Amazon.

• SellerAmp SAS: fast profit and eligibility checks for online arbitrage and wholesale. Plans cost $19.95, $29.95 and $49.95 per month, with a 14-day free trial. Read our SellerAmp review.
• Seller Assistant: adds IP-complaint and hazmat warnings, product matching across retailer sites and bulk tools. Pro costs $29.99/month ($299.99/year), with higher Business tiers and a 14-day trial. See our Seller Assistant App review.

Whichever calculator you choose, pair it with Keepa: the calculator tells you whether a product is profitable today, and Keepa tells you whether that price and sales rank are likely to hold.

How to Choose the Right Amazon Seller Extension

• Online or retail arbitrage: Keepa plus one profit calculator (SellerAmp SAS, Seller Assistant or RevSeller).
• Wholesale: a calculator that supports bulk or spreadsheet analysis, plus Keepa.
• Private label: a research suite such as Jungle Scout or Helium 10.
• Tight budget: start with free tiers and trials, and cancel tools you do not use every week.

Final Thought

Chrome extensions are some of the most cost-effective tools an Amazon seller can use. Several have free versions, and the paid ones usually pay for themselves by stopping one bad purchase. Use them for fee calculations, sales forecasting, keyword research and competitor analysis, and review your stack every few months: tools change prices and features often, and some older extensions on this list are no longer actively maintained.

FAQs

What is the best Chrome extension for Amazon sellers?

For arbitrage sellers, Keepa combined with a profit calculator such as SellerAmp SAS, Seller Assistant or RevSeller is the most common setup. Private label sellers usually prefer Jungle Scout or Helium 10 for product and keyword research.

Are there free Amazon seller Chrome extensions?

Yes. Keepa has free basic charts, The Camelizer, AMZ Base and the basic DS Amazon Quick View are free, and the Helium 10 and SellerApp extensions can be used with free accounts with limits. Most serious sourcing work still needs at least one paid tool.

Does Amazon have an official Chrome extension for sellers?

Amazon offers the Amazon Seller app for phones, which can scan products and check eligibility, but the popular Chrome extensions for sellers, including the “Amazon FBA Keyword Tool”, are made by third parties.

Do I need Keepa if I already use SellerAmp or RevSeller?

Usually yes. Calculators show today’s fees and profit, while Keepa shows price, sales rank and offer history, which tells you whether a deal is likely to stay profitable.
