10 Best Amazon Seller Tools of 2026

Jungle Scout ranks first because its Catalyst plans cover the research work most Amazon sellers start with, at a price a first-time seller can carry. Starter costs $29 a month billed annually and includes the browser extension, Product Database, Opportunity Finder, Keyword Scout and a Sales Estimator with 500 estimates a month. The limits are tight on that tier: 50 keyword searches, 100 product database searches and 30 days of product tracking history. Growth Accelerator, at $49 a month billed annually, lifts the Opportunity Finder and Product Database caps, raises Keyword Scout to 250 searches a month and adds a rank tracker for 500 keywords, a listing builder, inventory manager, review automation, advertising analytics and FBA reimbursements. Brand Owner + CI adds competitive benchmarking, market analysis and three seats. Jungle Scout does not offer a free trial, but standard plans carry a 7-day money-back guarantee. Brands above $1M a year are pointed to Cobalt, which is sold through a demo.

Sellerboard ranks second because it answers the question research tools leave open: how much money each product actually makes. The profit dashboard pulls in Amazon fees, ad spend, returns and your cost of goods, and indirect expenses can be added so the totals match your books. Around that core it adds inventory planning, automated review requests, listing change alerts, PPC optimization, a repricer and a service that claims refunds for lost inventory. Standard costs $19 a month, or $15 a month billed annually, and covers up to 3,000 orders a month. Professional at $29, Business at $39 and Enterprise at $79 a month raise order limits, follow-up emails, seller accounts and users. Every plan starts with a 1 month free trial and no card. The tradeoff is scope: Sellerboard lists a keyword research tool and a Chrome plugin, but sellers looking for product ideas will still want a research suite next to it.

Helium 10 has the broadest toolset here, which is why it scores highest on features, but its prices keep it in third place. Platinum, at $129 a month or $99 a month billed yearly, is pitched at sellers up to $100K a year and covers product research, the Chrome extension for Amazon and Walmart, keyword research with 100 searches a month, rank tracking, an AI-enhanced listing builder and basic profit reporting. Diamond, at $359 a month or $279 billed yearly, targets brands between $100K and $10M a year and adds Helium 10 Ads with rules-based automation and dayparting, the Helium AI agent, full inventory management, profit and loss reporting and long-term keyword trends. Both plans include Amazon FBA and ads training and a managed refund service, which takes a fee on recovered amounts. TikTok Shop tools sit in the same account. Enterprise starts at $1,499 a month billed annually.

SmartScout organizes Amazon data by level: product, keyword, brand, seller and category, and each plan unlocks a higher level. Basic, at $49 a month or $29 billed yearly, gives product level data on more than 30 million active products, keyword research through Search Terms Explorer, the Chrome extension, a Price List Scanner, a sales estimator and review automation, with 5,000 ASINs a month. Essentials, at $119 a month or $99 billed yearly, adds brand level data on 500,000+ brands, unlimited keyword research and tracking and historical search trends. Business, at $299 a month or $239 billed yearly, adds seller data on 2,000,000+ sellers with buy box history, subcategory data, sentiment analysis, brand reports and MCP access. That structure suits wholesalers looking for brands to approach and agencies prospecting sellers. Private label beginners may find the higher tiers more than they need. All plans carry a 7-day money-back guarantee.

AMZScout keeps buying simple: one AI Toolset plan at $59.99 a month or $399.99 a year, which works out to $33.33 a month. It includes the PRO AI Extension, which checks a product's competition and trend direction on Amazon pages, plus a Product Database for niche ideas, a Product Tracker for daily sales and rating changes, keyword search, reverse product keyword lookup and a keyword tracker that checks indexing and organic rank. Listing and review tools come in the Pack for Private Label add-on, and arbitrage and wholesale checks come in the Pack for Reselling add-on, each $99.99 a year. A separate MCP plan lets Claude or ChatGPT query Amazon data, starting at $39 a month for 100 data requests. AMZScout has no profit dashboard, ads tools or inventory planning, so it fits the research stage only. Purchases carry a 10-day money-back guarantee.

Seller Assistant is the strongest fit here for resellers, people who buy existing branded products wholesale or at retail and resell them on Amazon. The extension shows profit, restrictions and IP-Alert risk flags while you browse, and Pro adds a Bulk Restriction Checker for 4,000 ASIN checks a month on monthly billing. Pro costs $29.99 a month and includes 2 seats, plus preview allowances of the Business tools. Business, at $79.99 a month, adds a repricer for 250 products, a Price List Analyzer with 150k product scans a month, purchase orders, supplier and warehouse records, invoice parsing, landed cost tracking, FBA shipment sync, an MCP server and API, Zapier, Make and n8n integrations. Business Plus raises the limits for wholesale teams. Private label sellers will find little keyword research here, so this ranks below the research suites. Business comes with a 14 day free trial.

SellerSprite is a research suite with an unusually deep keyword section. Besides product, competitor and category research, it offers keyword mining, reverse ASIN, reverse lookup across several ASINs, traffic comparison, ABA opportunity data, keyword conversion rates, a realtime bid tracker and an index checker. Trackers watch products, keywords and new listings, and the free Chrome extension brings sales estimates and reviews onto Amazon pages. The Basic plan costs $390 a year billed annually and includes 50 tracked products, 250 tracked keywords and 25 new listing trackers with one main account. Standard, at $790 a year, adds 3 child accounts and doubles the trackers. An API and MCP server bring the data into your own tools. There is no unconditional refund, only a refund for unused time, so try the 3-day trial of the monthly plan before committing. We rank it below Jungle Scout because the menus are dense for new sellers.

Keepa is the data layer under a lot of Amazon research. The Keepa Pro subscription opens a Product Finder that filters millions of products, a Product Viewer that imports and exports lists in bulk, Buy Box statistics, current and historical stock levels for every offer, and advanced graphs of sales rank, offer counts and ratings. Pro also adds top seller lists, the category tree, full Deals table access and expanded price tracking for up to 10,000 products. Data requests draw from a quota that refills by 5% per hour, which allows, for example, up to 36,000 products a day through the Product Viewer. Keepa does not research keywords, build listings or track profit, so it serves resellers and analysts best. The pricing page showed us €29 a month, so the USD price is marked pending.

DataHawk is aimed at brands and agencies that have outgrown research tools and need reporting. It pulls Amazon and Walmart data into one platform with daily SKU-level analytics, ad metrics, profitability signals, SEO data and inventory, then layers executive dashboards and daily performance alerts on top. Agencies get multi-account dashboards, white-label reports and role-based access, and enterprise teams can connect BI tools for forecasting. A sales estimates feature supports competitor benchmarking. DataHawk also offers an MCP connection for AI assistants and is testing Sherlock, an AI agent that explains performance changes, with a waitlist. Pricing is custom and sold on annual plans, with onboarding, customer success check-ins and optional paid professional services. That makes it a poor fit for a seller still choosing a first product, and we score its value lower because no price is published.

ZonGuru has moved its product to Helix, a listing engineering service rather than a broad research suite. Helix reads keyword volumes and ranking data for your niche, competitors' listings and the questions shoppers ask Amazon's assistant, then rebuilds your listing to serve both keyword search and AI shopping. Plans are priced by managed listings and monthly rebuilds, called transformations. Starter costs $149 a month, or $124 billed annually, for 15 managed listings and 5 transformations. Growth at $299 a month covers 50 listings and 10 transformations, and Pro at $699 a month covers 100 listings and 25. Every plan includes monitoring and alerts, an AI Readiness Score, an SP-API Seller Central connection and MCP access. Helix only works for US and UK marketplaces. It ranks last because it covers one stage of selling at a high price per listing, but the free readiness score is a low-risk way to see where listings stand.
