12 Best Amazon Seller Tools 2026: Real Prices and Free Options Compared

Helium 10 is the best Amazon seller tool if you want one subscription for product research, keywords, listings, and PPC. SmartScout is the pick for wholesale and brand research, Jungle Scout for product and supplier research, and Keepa's free extension belongs in every seller's browser.

The cheapest plan is rarely the one you need. Helium 10's full profit reporting sits on Diamond, Jungle Scout's Sales Analytics skips its Starter plan, and ZonGuru prices its Seller plan by how many SKUs you sold. I checked every price below on the vendor pricing pages in September 2026.

• Best all-in-one: Helium 10, $129/mo or $99 billed yearly.
• Best for wholesale research: SmartScout, $49/mo or $29 billed yearly.
• Best for product and suppliers: Jungle Scout, $49/mo or $29 billed yearly.
• Best for keyword clusters: Data Dive, from $39/mo.
• Best free tool: Keepa's Chrome extension; Pro is €29/mo.
• Best for influencer research: Spreesy, $59/mo.

How I Picked These Amazon Seller Tools

I picked these 12 tools by the job each one does best. Then I checked every price, plan limit, and trial on the vendor pricing pages in September 2026. Four questions set the order. How much of the job does the tool cover? Which plan unlocks it? What does it cost, and what does it leave out?

I tested Spreesy's influencer search on a real ASIN myself. For the other tools, I worked from pricing pages, public demos, and vendor documentation, so the verdicts compare plans and features rather than a side-by-side sales test.

Helium 10 - Best Overall Amazon Seller Tool

Helium 10 is the widest Amazon seller suite on this list, with 25+ tools. It covers product research, keywords, listings, operations, and PPC. Platinum costs $129 a month, or $99 billed yearly. Diamond, at $359 or $279 yearly, adds full profit reporting, ad automation rules, and the Helium 10 MCP server.

Expand

Even though Helium 10 is a generalist tool at heart, it includes powerful advertising features through Helium 10 Ads, its integrated PPC platform. Basic functionality is available starting with the Platinum plan, while full access comes with the Diamond plan.

The only things missing from Helium 10 are launch promotions and a built-in repricer, so budget for a separate repricer if you compete on shared listings.

Helium 10 no longer lists a free plan on its pricing page. You can still sign up for its free tools, including the Chrome extension, a keyword tool, and a sales estimator, to test the data before you pay. The Helium 10 pricing breakdown compares Platinum and Diamond line by line.

Quick note: if listing copy is the job you care about most, I rank the dedicated Amazon listing optimization tools separately.

• Fits: sellers who want research, listings, and PPC behind one login.
• Standout: Helium 10 Ads plus Cerebro, Magnet, and Black Box on one plan.
• Watch-out: full profit reporting and ad automation rules need Diamond.

Our Verdict: Helium 10 is a top Amazon FBA tool with an extensive suite of features designed for Amazon beginner, intermediate, and expert sellers.

Jungle Scout - Best for Amazon Product and Supplier Research

Jungle Scout is the product research specialist of the big suites. Opportunity Finder, Product Database, and Product Tracker cover niche hunting. Its Supplier Database finds manufacturers in the US and Europe, not just Asia. Starter costs $49 a month, or $29 billed yearly, with a 7-day money-back guarantee.

Expand

Jungle Scout reports on ads rather than running them. From Growth Accelerator, at $79 a month or $49 billed yearly, you get Advertising Analytics, Negative Keyword Harvesting, Sales Analytics, and FBA reimbursements. There is no bid automation, so pair it with an ad tool if PPC is your main lever. The Jungle Scout pricing breakdown lists every plan limit.

However, it has integrated AI into its sales analytics, customer support, product research, and listing optimization. That helps you synthesize unique insights faster and save resources, such as money you’d have spent on outsourcing listing creation.

Want more niche-hunting options? My best Amazon product research tools list compares seven of them head to head.

• Fits: first-time private label sellers choosing a product and a supplier.
• Standout: supplier search beyond Asia, plus AI-written profit reports on Growth Accelerator.
• Watch-out: no free trial, only a 7-day money-back guarantee.

Our Verdict: Jungle Scout is an excellent tool for discovering unique product ideas, accurately estimating sales, and finding a perfect-fit supplier.

SmartScout - Best for Wholesale and Brand Research

SmartScout zooms out from single products to the whole marketplace. Its Brands dashboard, Subcategories tool, Seller Map, and Suppliers database show who wins each niche and where the gaps are. Basic costs $49 a month, or $29 billed yearly. Business, at $299 or $239 yearly, adds seller-level data and MCP access.

Expand

SmartScout is perfect for wholesale sellers and private label brands looking for market gaps. It shows how many products a brand owns, how they perform, and who they compete with, so you can choose the right category and position your product better.

Recent additions include AI Listing Architect for listing copy, Search Trends for shifting buyer behavior, and historical Search Query Performance data.

Essentials, at $119 a month or $99 billed yearly, unlocks brand and keyword-level data. Every plan comes with a 7-day money-back guarantee instead of a free trial. The SmartScout pricing breakdown shows which data each plan unlocks.

• Fits: wholesale sellers and brands hunting for under-served subcategories.
• Standout: brand, seller, and subcategory data most suites do not show.
• Watch-out: seller-level data and MCP sit on the $299 Business plan.

Our Verdict: SmartScout is for sellers who want to stop guessing and start spotting real opportunities. It’s especially useful if you’re in wholesale or looking to break into overlooked niches.

AMZScout - Best for Beginners, Dropshipping, and Arbitrage

AMZScout is the gentlest start for new sellers. Its Product Database, Product Tracker, and ready-made product reports hand you ideas instead of a blank search box. One AI Bundle plan costs $59.99 a month, $169.99 for three months, or $399.99 a year. The yearly plan adds an MCP connector for Claude and ChatGPT.

Expand

AMZScout also sells a Chrome extension for dropshipping, wholesale, and retail arbitrage research, which suits sellers who source through several models at once. That extension and the other booster packs cost extra on top of the AI Bundle.

Aside from product research, AMZScout also offers keyword research, competitor research, and listing-building tools. However, its keyword research tools may not be as deep as Helium 10’s or Jungle Scout’s.

Likewise, the software lacks sales analysis for tracking revenue and profits and doesn’t do ad setup or analysis. This might be a turnoff for Amazon FBA sellers looking for an all-in-one tool.

• Fits: new sellers who want ready-made product ideas.
• Standout: product reports plus an MCP connector on the yearly plan.
• Watch-out: no profit analytics or PPC tools, and add-on packs cost extra.

Our Verdict: AMZScout is best for private label, wholesale, and retail arbitrage Amazon sellers who want to research the best product type for their sales strategy. It’s also great for sellers who want ready-made product ideas.

Data Dive - Best for Keyword Clustering & Reverse ASIN Analysis

Data Dive is built for sellers who rebuild listings from competitor keyword data. It clusters reverse-ASIN keywords by relevance, writes AI listing briefs, and tracks rank with Rank Radar. Starter costs $39 a month for 100 Dive ASINs. Standard is $149 and Enterprise is $490, with two months free on yearly billing.

Expand

Created by seller Brandon Young and his team at Seller Systems, Data Dive helps you reverse-engineer top-performing products using clustered keyword data and AI-generated listing briefs. Instead of just throwing keywords into a tracker, Data Dive organizes them by buyer intent, search volume, and ranking potential, so you know which ones to focus on.

You can run ASIN dives (reverse-ASIN reports), identify gaps in competing listings, and generate ready-to-edit listing briefs based on top competitors’ performance. Its Listing Builder integrates these briefs into optimized titles, bullets, and backend terms.

Data Dive also includes a PPC Campaign Builder and a Keyword Rank Tracker, making it ideal for sellers who want to build their content and ads from the same keyword base.

Yearly billing brings the plans to $32, $124, and $408 a month, and Data Dive lists no free trial. The Data Dive discount page tracks the current partner offer.

For more ways to mine competitor listings, see my reverse ASIN tool rankings.

• Fits: private label sellers optimizing listings and PPC from one keyword base.
• Standout: keyword clusters and AI listing briefs built from real competitor data.
• Watch-out: Standard jumps to $149 a month, so price the plan you will actually use.

Our Verdict: Data Dive is a high-powered keyword and listing tool best suited to sellers who want to dominate their niche with data-backed content and ad strategies.

ZonGuru - Best Beginner Suite With a Business Dashboard

ZonGuru bundles product research, listing optimization, and store metrics into one beginner-friendly suite. Researcher costs $49 a month, or $29 billed yearly, for six research and listing tools. Seller adds the Business Dashboard, Keyword Tracker, Product Pulse alerts, and review automation. It is priced by the SKUs that sold in the last 90 days.

Expand

However, ZonGuru stands out because of its Business Dashboard. While Helium 10 and Jungle Scout also have intuitive dashboards, ZonGuru includes traffic stats to break down traffic sources, page views, and conversion rates.

Seller starts at $49 a month billed yearly for 1 to 20 selling SKUs, and the price rises with each SKU band after that. Count your SKUs with sales in the last 90 days before you choose a plan. Product Pulse flags new reviews and hijackers, and Review Automator sends review requests for you.

The ZonGuru pricing breakdown lists every SKU band, and the standing ZonGuru offer takes 20% off any plan for life.

• Fits: sellers researching a first product who want store metrics later.
• Standout: a Business Dashboard with sessions, conversion, ACoS, and TACoS.
• Watch-out: the Seller price rises once you pass 20 selling SKUs.

Our Verdict: ZonGuru is a good first suite for sellers researching a first product who want store metrics in the same login later. Check your SKU count before choosing the Seller plan.

Scale Insights - Best for PPC Automation

Scale Insights automates Amazon PPC without a sales call. You connect the account and set ACoS or TACoS targets. Its rules and Scale Optimizer AI then adjust bids hourly. Plans start at $78 a month for 5 automated ASINs and reach $688 for 100. The 1% Plan covers unlimited ASINs for 1% of monthly ad spend.

Expand

Its selling point is control. You can run Scale Insights’ own automation rules, write your own, or mix both, and hourly bid adjustments, dayparting, and negative keyword workflows come standard.

Yearly billing takes 20% off every plan, and the 30-day free trial needs no credit card.

The limit is scope. Scale Insights only manages Amazon ads, so you still need a separate tool for product research, keywords, and listings.

If ads are your growth lever, I break down eight bid managers in my Amazon PPC software comparison.

• Fits: sellers spending enough on ads to want hourly bid rules.
• Standout: public pricing and full control over the automation rules.
• Watch-out: it only manages Amazon ads.

Our Verdict: Scale Insights is ideal for sellers who want automated PPC with a public price and full control over the rules. Brands that need AMC-level analytics should look at Intentwise instead.

Intentwise - Best for Brands and Agencies With Big Ad Budgets

Intentwise is commerce data infrastructure for brands and agencies with large ad budgets. Its Foundation platform pulls advertising, retail, shopper, and competitive data into one Data Store. You can query it from BI tools or through the Intentwise AI Gateway (MCP). Pricing is custom and starts with a demo.

Expand

Choose it when your ad data spans several Amazon ad products and your team already works in a BI tool or data warehouse. Smaller sellers will get more from Scale Insights or Helium 10 Ads. The guide on how to try Intentwise before buying covers the demo process.

• Fits: brands and agencies with a data team and ad spend across several Amazon ad products.
• Standout: one data store that feeds BI tools and AI assistants.
• Watch-out: no public pricing, so budget for a sales process.

Our Verdict: Intentwise suits brands and agencies with a data team and large ad budgets. Everyone else should start with a self-serve PPC tool.

Spreesy - For Finding Amazon Influencers by Product

Spreesy is the tool I would consider when your next task is finding Amazon influencers to approach about a product. Search a competing ASIN, inspect the people recommending it, and review their published contact routes. It is a focused seller-research subscription at $59 a month, with a workflow separate from listing or PPC software.

Expand

I searched the Levoit Core 300-P, ASIN B07VVK39F7. Spreesy returned 2,224 influencer matches across shoppable videos, photos, and product lists. Opening one profile showed both a standalone review and comparisons tagged with multiple products. That distinction is useful when you need a filmed demonstration rather than a list mention.

The match still needs review. A keyword suggestion is weaker evidence than an exact ASIN relationship, and some profiles have no listed contact links. During my test, the product name was unavailable even though the exact matches loaded. Saved lists and CSV export help organize research, subject to your account’s limits.

There is no full paid-workspace trial. Signup and the public coverage check are free, and Spreesy advertises a 30-day refund on the first charge. Check the results for your products before subscribing.

Our verdict: Spreesy fits Amazon sellers who want a standalone influencer research workflow. If you already use Helium 10, try your included Influencer Finder searches first. Both tools accept ASINs. My real product-to-shortlist walkthrough shows how I would decide which matches to approach.

Shopkeeper - Best for In-Depth Amazon Profit Analytics

Shopkeeper is a dedicated profit tracker that prices by monthly order volume and includes every feature on every plan. Starter costs $20 for up to 250 orders, and Superseller costs $250 for 10,000. It tracks 50+ Amazon fee types, forecasts inventory months ahead, and exports to QuickBooks and Sage.

Expand

But why consider Shopkeeper when Helium 10 already has sales analytics? Even though Helium 10’s Profits tracks sales and seller fees, Shopkeeper monitors up to 50+ types of fees that you may be charged per sale.

Its inventory forecast looks months ahead, where Helium 10's forecast stops at seven days.

However, this app doesn’t offer Amazon PPC optimization, competitor research, product and keyword research, or help with other aspects of your Amazon FBA business.

The Shopkeeper pricing breakdown lists every order band, and every tier includes the full software.

More profit dashboards worth a look sit in my Amazon analytics tools roundup.

• Fits: small stores that want true profit per SKU without research tools.
• Standout: every feature on every plan, from $20 a month.
• Watch-out: the price climbs fast once you pass 1,000 orders.

Our Verdict: Shopkeeper is ideal for Amazon sellers seeking serious financial and data analytics on their store’s performances. Its inventory management system is also a nice add-on.

Nova Analytics - Best for Multi-Account Profit Tracking

Nova Analytics is the profit tracker to pick when Shopkeeper's single-account view runs out. It rebuilds net profit from 200+ Amazon cost lines and refreshes hourly across 21 marketplaces. It then rolls the P&L up by brand, supplier, lifecycle, or account manager.

Expand

Nova includes its MCP server on every plan, with unlimited calls. Add one server URL to Claude, ChatGPT, or Gemini and the assistant can query live metrics, from keyword-level PPC spend to days of inventory, with fees and returns already reconciled.

Agencies get a consolidated P&L per client account with role-based access. The Listing Health Scanner ranks suppressed listings, lost Buy Boxes, and hijackers by the revenue they put at risk.

Like Shopkeeper, Nova does not do product research, keyword research, or PPC bid changes, so it belongs next to Helium 10 or Jungle Scout rather than in place of them.

Pricing starts at $49 a month per Seller Central account with every feature included and a 14-day trial that needs no card. Agencies get custom pricing, and Nova does not publish the tiers above $49.

Our Verdict: Nova Analytics is the best profit tracker on this list for sellers with several brands or accounts, and its MCP server comes with every plan. Single-account sellers under 3,000 orders get better value from Sellerboard. See my full Nova Analytics review for the pricing math.

Keepa - Best Free & Paid Tool for Price and Sales Tracking

Keepa shows price history, sales rank trends, and stock availability for nearly any Amazon product. The free Chrome extension puts those charts on every listing, which is why wholesale and arbitrage sellers install it first. Keepa Pro costs €29 a month and adds deeper product data, alerts, and the Product Finder.

Expand

The free version of Keepa allows you to see historical pricing and sales rank charts directly on Amazon listings via its Chrome extension. This is useful for spotting pricing patterns, seasonality, and buy box trends, especially for wholesale and arbitrage sellers.

With the paid plan (€29/month, around $34), you get advanced features like price drop alerts, sales rank tracking, stock level monitoring, and category-wide product tracking. These tools help you time inventory buys, avoid price wars, and spot emerging opportunities.

Keepa is especially valuable for resellers, but even private label sellers can use it to validate pricing trends in their niche or track competitors’ launches over time.

Our Verdict: Keepa is an essential tool for price tracking, whether you’re just getting started or managing a large catalog. It’s one of the most valuable “freemium” tools available to Amazon sellers.

Free Amazon Seller Tools Worth Using First

You can cover a surprising amount of seller work for free before paying for a suite. Amazon's own tools handle product ideas, A/B tests, and fee estimates. Keepa's extension adds price history, and Helium 10's free tools add keyword and sales estimates. Paid suites earn their cost once you need tracking and automation.

• Product Opportunity Explorer: Amazon's niche and demand data, inside Seller Central.
• Revenue Calculator: Amazon's fee and profit estimate for FBA versus your own fulfillment.
• Manage Your Experiments: Amazon's A/B tests for product content.
• Brand Analytics: search, repeat purchase, and market basket data for brand owners in Brand Registry.
• Keepa's free extension: price and sales-rank history on every listing.
• Helium 10 free tools: Chrome extension, keyword tool, sales estimator, and a PPC audit.

Our own free calculators cover the math behind these decisions. The FBA calculator, ACoS calculator, and reorder point calculator need no account.

Which Amazon Seller Tools Work With Claude and ChatGPT?

Five tools on this list now connect to AI assistants through MCP. MCP is the protocol Claude and ChatGPT use to read outside data. Access sits on different plans, so the cheapest plan often lacks it. Nova includes it everywhere, while Helium 10 and SmartScout reserve it for their top self-serve plans.

Jungle Scout also sells an MCP product, but it sits with its brand and enterprise offers rather than inside the Catalyst seller plans.

What a Starter Stack Costs by Seller Type

Most sellers end up with one suite plus one specialist. The table prices four common stacks on yearly billing, using the cheapest plan that covers each job. Treat it as a first-year budget ceiling. Drop any tool you have not opened in 30 days.

Monthly billing raises every row. The same four stacks cost $49, about $83, $59, and $207 a month without an annual commitment. Keepa Pro is billed in euros, so the dollar figure moves with the exchange rate.

How to Choose the Right Amazon Seller Tools

Start with the job that costs you the most time or money this month. Then pick the tool built for that job, and check whether software you already pay for covers it. Compare the plan that unlocks the job, not the entry price. Commit to yearly billing only after a month of real use.

• Choose Helium 10 if: you want research, listings, and PPC in one subscription.
• Choose Jungle Scout if: you are picking a first product and a supplier.
• Choose SmartScout if: you sell wholesale or research brands and subcategories.
• Choose Data Dive if: you rebuild listings and PPC from competitor keywords.
• Choose Scale Insights if: ads are your growth lever and you want control over the rules.
• Choose Keepa if: you need price history before you buy inventory.

Still mapping demand first? Start with my Amazon keyword research tools comparison before you commit to a full suite.

And if you compete on shared listings, a dedicated Amazon repricer will move the needle faster than any all-in-one plan.

The Verdict

Helium 10 is the best Amazon seller tool overall because it covers research, keywords, listings, and PPC behind one login. SmartScout and Data Dive beat it on their specialties, wholesale data and keyword clusters. Start with Keepa's free extension and Amazon's own tools. Then add one paid tool for the job that slows you down most.

For influencer discovery, compare Spreesy with the access included in your current Helium 10 plan. For other jobs, choose the specialist that addresses your immediate bottleneck. Avoid adding a subscription until you can explain what work it will improve.
