Best Amazon Seller Tools in 2026: 9 Picks, Compared by Job

If you want one subscription that covers product research, keywords, listings, ads and profit, it is Helium 10. The plan that includes all of it is Diamond, at $279 a month billed yearly or $359 monthly. Platinum costs $99 a month billed yearly or $129 monthly, but it caps keyword research at 100 searches a month and has no rank tracking or Helium 10 Ads (Helium 10’s pricing page, checked 10 October 2026).

Helium 10 isn’t the right first purchase for everyone. Several jobs are done better, or for less, elsewhere:

• Product research: Jungle Scout’s Growth Accelerator plan covers finding, validating and sourcing products for $49 a month billed annually.
• Profit tracking: sellerboard tracks profit from your own Amazon account data, from $19 a month.
• Market and wholesale research: SmartScout maps brands, sellers and subcategories, which product-first tools don’t.
• PPC on a small budget: under roughly $3,000 a month of ad spend, Amazon’s own Campaign Manager is free, and Teikametrics has the lowest published price of the dedicated platforms we compared.

How we picked. We compared each tool on the job it is built for, on what its entry plan includes according to the vendor’s own pricing table, and on its published price, checked on 10 October 2026. Vendor claims are attributed and linked, and how we test explains the method.

Amazon seller tools and software compared

Best all-in-one Amazon seller tool: Helium 10

Helium 10 is the broadest tool on this list. Its Solutions menu groups the tools under seven headings: AI, product research (Black Box, Xray, Product Launchpad), keyword research (Cerebro, Magnet and Keyword Tracker), listing optimization (Listing Analyzer, Listing Builder), daily operations (Profits, Follow-Up, Inventory Management, Managed Refund Service, Alerts), analytics (Market Tracker, Search Query Analyzer) and advertising (Helium 10 Ads) (helium10.com, checked 10 October 2026).

The plan you buy matters more than the tool list:

Helium 10’s pricing page lists no free plan; a limited free account exists, and there is no free trial of the paid plans. Helium 10 no longer sells the Starter plan either, so Platinum is the cheapest paid plan. Correction (10 October 2026): an earlier version of this page listed Free as a fourth Helium 10 tier. It is not one.

Who should skip it: anyone who hasn’t chosen a product yet (free tools and a cheaper research plan will do), anyone whose main job is keyword research on a Platinum budget, where a 10-ASIN Cerebro search uses 10 of the month’s 100 searches, and anyone whose only problem is knowing their margin. The full plan limits are in our Helium 10 pricing guide.

Best for product research: Jungle Scout

Jungle Scout is our product research pick because one mid-priced plan covers finding, validating and sourcing a product. On Growth Accelerator, Jungle Scout’s pricing table shows no cap on Product Database or Opportunity Finder searches, 150 tracked products, 250 Keyword Scout searches a month and the Supplier Database (Jungle Scout’s pricing page, checked 10 October 2026).

Jungle Scout Starter costs $29 a month billed annually ($348 a year) or $49 month to month. Growth Accelerator is $49 a month billed annually ($588) or $79 monthly. Brand Owner is $129 a month billed annually ($1,548) or $149 monthly, and includes 3 seats.

Starter is a sampler: 100 Product Database searches and 50 Keyword Scout searches a month, one month of keyword history, and no Supplier Database or data exports. There is no free trial. New customers on regularly priced plans get a 7-day money-back guarantee, and refunds are requested through support. Jungle Scout’s own new-customer offer prices Growth Accelerator at $441 for the first year, renewing at $588 (checked 10 October 2026).

Who should skip it: anyone selling on Walmart or TikTok Shop as well as Amazon, since Jungle Scout’s help center says it covers Amazon marketplaces only. Our Jungle Scout pricing guide compares the plans, and best Amazon product research tools sets Jungle Scout against Helium 10, SmartScout and the free options.

Best for keyword research: Helium 10, or SmartScout for less

Helium 10’s Cerebro now does both halves of keyword research. Helium 10’s help center says Magnet has been merged into it (notice last updated 6 January 2026), so one tool runs reverse-ASIN lookups on up to 10 ASINs and seed-keyword searches, even though helium10.com’s Solutions menu still lists Magnet on its own. The limit depends on the plan: the help center lists 300 Cerebro searches a day on Diamond and 100 a month on Platinum, where each ASIN in a multi-ASIN search counts as one search.

SmartScout is the cheaper route to heavy keyword work. SmartScout Essentials, at $99 a month billed yearly or $119 monthly, includes what its plan card calls “Unlimited Keyword Research & Tracking”. SmartScout’s Rank Maker page says the tool is included in every plan, but its pricing table starts it at Essentials, and the table is what you are billed against.

Two cheaper specialists are worth knowing:

• SellerSprite: SellerSprite Basic is $39 a month (shown against a $49 list price) or $390 a year, with a free 3-day trial of the monthly plan. The monthly Basic plan has no keyword tracker; the annual one tracks 250 keywords.
• MerchantWords: MerchantWords Silver is $35 a month or $350 a year; Gold $79 or $790; Platinum $149 or $1,490. It is a search-term database rather than a workflow, and it offers no free trial.

Who should skip the specialists: anyone already paying for Helium 10 Diamond, Jungle Scout Growth Accelerator or SmartScout Essentials. Our keyword research tools and reverse ASIN tools guides compare them in depth.

Best Amazon listing tool: Helium 10, or Data Dive for heavy optimization

Helium 10 is our listing pick for most sellers, because one subscription covers the chain from keyword research to an indexing check, and the listing tools cost nothing extra if you already pay for it. Platinum includes Listing Builder (20 listings), Scribbles, Listing Analyzer (50 uses a month) and Index Checker (150 uses), according to Helium 10’s help-center plan guide, although AI-written listings are mostly a Diamond feature: the guide gives Platinum 5, lifetime. Our listing optimization tools guide has the full comparison, including Amazon’s own free listing tools. SmartScout’s AI Listing Architect is on every plan, from one ASIN a month on Basic.

Data Dive is the specialist for sellers who optimize many listings. A “Dive” builds a Master Keyword List from a set of competitors, showing each one’s organic and sponsored rank, search volume and a relevancy score (Data Dive help center). Rank Radar then tracks your rank daily alongside PPC data, and the AI Copywriter, which Data Dive says is available on every tier, drafts titles and bullets.

Data Dive Starter is $39 a month, or about $32 a month billed yearly; Standard is $149 or $124; Enterprise is $490 or $408 (Data Dive’s pricing page, checked 10 October 2026). Data Dive doesn’t print yearly totals, and it offers no free trial or money-back guarantee. Starter, which Data Dive labels “For Light Research”, covers 100 Dive ASINs and 25 Rank Radar keywords.

Correction (10 October 2026): we previously listed Data Dive yearly totals of $384, $1,488 and $4,896. Data Dive doesn’t display yearly totals; those figures were our own arithmetic.

Who should skip Data Dive: sellers who rewrite a listing or two a year; Helium 10’s or Amazon’s own listing tools are enough at that volume. AI copywriters, including Data Dive’s, are compared in best AI tools for Amazon sellers.

Best for profit tracking: sellerboard

Research tools estimate a product’s margin from public data before you sell it. Once you are selling, your real margin, after FBA fees, storage, refunds and advertising, is in your own Amazon data, and the gap between the estimate and the real figure is where money goes missing. A profit tracker reads that data.

sellerboard Standard costs $19 a month, or $179 a year billed annually; Professional is $29 ($279 a year), Business $39 ($369) and Enterprise $79 ($759). sellerboard offers a 1-month free trial with no credit card (sellerboard.com, checked 10 October 2026). The plans differ mainly by order volume, from 3,000 orders a month on Standard to 50,000 on Enterprise. sellerboard says every plan includes a real-time profit dashboard, listing-change alerts, PPC optimization, inventory management, refunds for lost inventory and an LTV dashboard.

Who should skip it: pre-launch sellers with nothing to track yet, and Helium 10 subscribers whose needs its Profits tool already covers. Helium 10 says Profits uses data from Amazon’s API, and Platinum includes it, with what its plan card calls limited profit reporting. Dedicated reimbursement services are compared in best Amazon reimbursement software, and the wider field in best Amazon seller analytics tools.

Best for PPC: it depends on your ad spend

Below roughly $3,000 a month of ad spend, Amazon’s own Campaign Manager is the right tool, because every paid platform takes a large share of a small budget. Above that, Teikametrics Essentials costs $149 a month billed annually or $179 month to month and covers up to $10K a month of ad spend, with a 30-day free trial. Advanced and Enterprise are custom-priced, plus 3% of ad spend over $10K (Teikametrics pricing, checked 10 October 2026).

Helium 10 Ads (formerly Adtomic) comes with Diamond, and Helium 10 charges a 2% management fee on all ad spend in profiles set to Managed. The best Amazon PPC tools guide works through what each option costs at each budget.

Best for market and wholesale research: SmartScout

SmartScout is organised around brands, sellers and subcategories rather than individual products, which suits wholesale sourcing and choosing a category. Its homepage claims 2M+ third-party sellers tracked and 40,000+ subcategories mapped (smartscout.com, checked 10 October 2026), and its Basic plan card covers 30,000,000+ products. If SmartScout doesn’t fit, our SmartScout alternatives page compares nine other tools, though few of them do the same job.

SmartScout Basic costs $29 a month billed yearly, or $49 month to month. Essentials is $99 billed yearly ($119 monthly) and Business is $239 billed yearly ($299 monthly). Enterprise is quoted after a demo (SmartScout’s pricing page, checked 10 October 2026). Each self-serve plan includes one user; extra users cost $49 each.

Correction (10 October 2026): SmartScout raised its prices after our 1 August 2026 check. Basic was previously $29 a month, Essentials $97 and Business $187 on monthly billing.

The tier you need depends on what you came for. The Search Terms Database is on every plan. The Brands Database and Rank Maker start at Essentials. The Sellers Database, Seller Map, Traffic Graph and Brand Reports start at Business. Search Terms Ad Spy is included on Enterprise and sold as a sales add-on on Business, and Share of Voice is Enterprise-only. There is no free trial; each self-serve plan carries a 7-day money-back guarantee for new customers.

On accuracy, SmartScout’s founder writes that its “analysis shows that we are within 80-90% accuracy on most brands and products” (SmartScout). That is the vendor’s own figure, not an independent test.

Who should skip it: a private-label seller who has already settled on a niche. SmartScout earns its price when you are comparing markets, brands or sellers, not when you are refining one product. Our SmartScout pricing guide has the full tier map, and best Amazon market intelligence tools sets it against the other market data platforms.

Best for reviews and ratings

Amazon’s rules leave little room here, and anything promising reviews outside Amazon’s terms is a liability, not a tool. The legitimate options:

• Amazon’s Request a Review button in Seller Central: free, and the baseline the paid tools automate.
• Helium 10: its pricing table ticks automated review requests on Platinum and Diamond, alongside Follow-Up email (5,000 emails on Platinum). Its separate Seller Assistant Chrome extension has been discontinued, and Helium 10’s help center points its users to Follow-Up.
• Jungle Scout: Review Automation starts on Growth Accelerator.
• SmartScout: Rating Booster allows 100 requests on Basic, 1,000 on Essentials and 20,000 on Business.

Who should skip all of it: sellers with low order volume, who can press Amazon’s button by hand in a few minutes a week.

Free Amazon seller tools worth using

Amazon Brand Analytics is free if you have a Professional selling account and are a brand representative for a brand enrolled in Amazon Brand Registry (Amazon). Its Search Query Performance, Search Catalog Performance and Top Search Terms dashboards are Amazon’s own search data, which paid keyword tools can only model. Our Brand Analytics guide explains the reports, and best Amazon search analytics tools covers the paid tools built on them.

Product Opportunity Explorer, in Seller Central under Growth, groups search terms into niches and reports demand, search volume, competition, reviews and returns from Amazon’s own data (Amazon).

SmartScout’s Chrome extension offers 100 free full-feature uses a month with no credit card, according to its Chrome Web Store listing, which showed 10,000 users and 4.1 stars from 15 ratings on 10 October 2026. SmartScout has no free plan, so this extension and a free brand report from its Brand Reports page (no credit card needed, checked 10 October 2026) are ways to see its data without paying. Details are in our SmartScout Chrome extension review.

Helium 10’s free tools include a keyword tool (a limited demo of Magnet), a PPC audit, a sales estimator, a trending-products list and the Chrome extension (helium10.com/tools). Helium 10’s pricing page claims 860K+ active Chrome extension users, and its Chrome Web Store listing shows 1,000,000 users (checked 10 October 2026). The extension’s full features need Platinum or above, and our Helium 10 free tools guide sets out what the limited free account includes.

Keepa’s price-history charts are free in its browser extension. Keepa Pro costs €29 a month or €290 a year, billed only in euros.

sellerboard’s free month needs no credit card, which makes it the easiest way to see your real margin before you pay anything.

The cheapest useful paid pair is sellerboard Standard ($19 a month) and SmartScout Basic ($49 a month, or $29 billed yearly): real profit numbers plus a working view of your market. It won’t do keyword research, but it will stop you selling something at a loss.

Four stacks that work

New seller, first product. Free tools until you have a shortlist, then Jungle Scout Growth Accelerator ($49 a month billed annually). Add sellerboard the month your first units go live.

Wholesale or arbitrage. SmartScout Essentials for the Brands Database, or Business if you need the Sellers Database and Seller Map, plus Keepa’s free charts and sellerboard. Keyword tools matter little here, because you aren’t writing listings. Our SmartScout wholesale workflow and best Amazon arbitrage tools cover the sourcing side, and best Amazon brand research tools the brand-finding step.

Private label, scaling. Helium 10 Diamond ($279 a month billed yearly) for keyword research without Platinum’s monthly cap, rank tracking and Helium 10 Ads; Data Dive Standard for listing work; sellerboard Professional for profit.

Agency or multi-brand. SmartScout Business for Brand Reports and Traffic Graph, Helium 10 Diamond for its 5 user logins and 10 connected Seller Central accounts, and sellerboard Business or Enterprise for multi-account profit. Budget for seats: SmartScout charges $49 per additional user, and Jungle Scout $49 a month or $459 a year per extra seat.

How to choose in five minutes

Answer these in order and stop at the first yes.

1. Don’t know your real margin per product? Buy a profit tracker first: sellerboard, free for the first month.
2. Haven’t chosen a product yet? Use the free tools, then Jungle Scout Growth Accelerator for research.
3. Is the listing your bottleneck? Helium 10 covers the listing chain from keywords to an indexing check; add Data Dive if you optimize many listings, and use Amazon’s free tools if you only write one or two a year.
4. Choosing between markets or brands rather than products? That is SmartScout: Basic to look around, Essentials for brand and keyword data, Business for seller and traffic data.
5. Spending real money on ads? Price the tools against your ad spend first, as in the PPC section above.

The common mistake is buying breadth to solve a depth problem: a $279-a-month suite for a $19 job, or a $299-a-month intelligence plan when what you needed was a better title. Name the bottleneck first, and the tool follows from it.

If the choice is down to the two biggest suites, our Helium 10 vs Jungle Scout comparison goes through them side by side.
