7 Best Keepa Alternatives for eBay Sellers (2026)

Quick answer: The best Keepa alternatives for eBay sellers are Ecomli, eBay Product research and CamelCamelCamel. Keepa charts Amazon prices, but it never touches your eBay listing. Ecomli makes the eBay dropshipping extension ranked first here, and it is our pick because its Stock Monitoring acts on a supplier price or stock change for you: it updates the eBay price and quantity, or ends the listing, using rules you set. eBay Product research is the best free source of eBay sold prices, and CamelCamelCamel is the best free Amazon price history.

Editor's Choice: Ecomli. Stock Monitoring keeps each listing in line with its Amazon or AliExpress supplier, Create Listings prices new items with your markup, and the Overview dashboard shows the profit that is left.

Most people who search for a Keepa alternative already know what Keepa does. They want the same price signal with less noise, a lower bill, or a tool that does something with the number. For an eBay seller, a chart only shows that a supplier price moved. What protects your margin is a listing that moves with it.

If finding products is your bigger gap, start with our hub on eBay product research tools.

This guide compares seven tools on that job. Prices were read from each vendor's own pricing page in November 2026, and every tool keeps a fair "best for" label below the top spot.

Keepa alternatives at a glance

The table ranks each Keepa alternative by how much of an eBay seller's price work it covers. "Acts on your eBay listing" means the tool changes the live listing itself, not just a chart or an email.

What Keepa does well, and where eBay sellers hit its limits

Keepa is an Amazon price tracker. Its Chrome Web Store listing says the Keepa extension "adds price history charts and the option to be alerted on price drops to all supported Amazon sites", and the listing shows 5,000,000 users. Keepa's own site says it tracks over 7 billion Amazon products. For checking whether an Amazon price is normal or a short spike, it is hard to beat.

That strength is also the limit. Keepa Amazon data lives on Amazon product pages and in Keepa's own interface. It does not read eBay sold prices, it does not know which of your eBay listings uses which supplier, and it cannot change a listing when the supplier price moves. Every alert still ends with you opening eBay and editing a price by hand.

That manual step is fine for a few dozen listings. It stops working once a store has hundreds of supplier-linked items, because the alerts arrive faster than anyone can act on them. A missed price rise means an order you fill at a loss, and a missed stock-out means a sale you cannot ship.

You may also know eBay tools such as ZIK Analytics for product research or Yaballe for dropshipping automation. They solve research and listing jobs, so this guide sticks to tools that track prices.

The right Keepa alternative depends on which part of the job you want covered. Some tools give you the same history for free. Others add research Keepa does not do. One group goes further and updates the listing.

Three jobs a price tracker can do for an eBay seller

Most Keepa alternative lists compare tools on chart quality alone. For an eBay store there are three separate jobs, and no single tool on this list does all three. The matrix shows which tool covers which job.

The three jobs are history (is today's supplier price normal?), alerting (tell me when it changes) and acting (change my listing when it changes). Keepa covers the first two for Amazon. Only two tools here cover the third, and only one of them is built for eBay alone.

The 7 Keepa alternatives, ranked

Each entry follows the same order: who it is best for, key features, pricing, pros, cons and a one-line takeaway. Competitor facts come from each vendor's live page in November 2026.

1. Ecomli: best for eBay dropshippers who need supplier price changes applied to their listings

Best for: eBay sellers who list products from Amazon and AliExpress and want each listing to follow its supplier's price and stock.

Ecomli is a non-API browser extension for eBay dropshippers. It works through the eBay seller account already signed in to your desktop Chrome browser, so there is no API connection to authorize. It helps you find products, create listings from Amazon and AliExpress with your own pricing rules, keep those listings in line with supplier stock and prices, and see your real profit on one dashboard.

Where Keepa tells you an Amazon price moved, Ecomli's Stock Monitoring checks the supplier price and stock for each listing Ecomli manages and then updates the eBay price and quantity, or ends an out-of-stock item, using the rules you set. If a supplier page cannot be read, the listing is held unchanged instead of being ended. That last rule matters, because a failed read is not a sold-out product.

Key features:

• Stock Monitoring for Amazon and AliExpress suppliers: your markup, an out-of-stock rule (set quantity to 0 or end the listing), a restock quantity and a price-change tolerance.
• Create Listings from Amazon and AliExpress links, priced with your markup, with optional AI titles and descriptions written from supplier facts.
• Product Hunting to research an eBay seller's sold history or current listings and match the products to Amazon or AliExpress.
• Safety Shield screens products and listing copy for flagged brands and restricted items before a listing publishes.
• Overview dashboard showing eBay sales, fees, refunds, supplier costs and recorded profit by day or period.

Pricing reality: Starter is $29/month with 1,000 monthly product imports, Pro is $99/month with 5,000, and Scale is $199/month with 10,000 plus 3 eBay account seats and 1 VA seat. Stock Monitoring is on every plan and every plan has unlimited active listings. Billing is monthly in USD with the First Sale Guarantee.

Pros:

• Acts on the change: price, quantity or end listing, without you editing eBay by hand.
• Covers Amazon and AliExpress suppliers in the same rules.
• Monitoring is included from the cheapest plan, with no cap on active listings.

Cons:

• eBay is the only selling channel.
• No price history charts, so it will not show whether a supplier price is a seasonal low.
• Tasks run in your desktop browser, so monitoring waits while the browser is closed.

Takeaway: Ecomli is the Keepa alternative for eBay dropshippers who want a supplier price change applied to the listing, not just charted.

2. eBay Product research: best free source of eBay sold-price history

Best for: any eBay seller who wants to know what an item really sells for on eBay before listing or repricing it.

Keepa answers "what does Amazon charge?". eBay Product research answers the other half: "what do eBay buyers pay?". It sits in the Research tab of Seller Hub, and eBay's help page says it gives access to the last 3 years of eBay sales data for millions of items, including sales trends, average sales price, sold price range and average shipping cost.

Key features:

• Searches across the last 3 years, where completed-listings search covers only items that sold in the previous 90 days.
• Filters by category, condition, brand and buyer or seller location.
• Shows sell-through and average sold price for a search term.

Pricing reality: free to use inside Seller Hub. eBay's Seller Hub help page says you need at least one sale before you can use Seller Hub.

Pros:

• The only tool here that shows eBay sold prices directly from eBay.
• No subscription.

Cons:

• No supplier prices and no alerts.
• It never changes a listing.

For a step-by-step method, see our guide to Terapeak product research on eBay.

Takeaway: pair eBay Product research with any supplier tracker, because it is the free answer to what eBay buyers actually pay.

3. CamelCamelCamel: best free Amazon price history and alerts

Best for: sellers who want Keepa-style Amazon price charts and target-price emails without paying for them.

CamelCamelCamel is the closest like-for-like swap for Keepa on this list. It is a free tracker dedicated to Amazon, with historical price charts and email alerts when a product hits a target price, which is how the live Google AI Overview for this search describes it in November 2026.

Key features:

• Amazon price history charts.
• Email alerts when an item reaches your target price.

Pricing reality: free.

Pros:

• Costs nothing and is simple to read.
• Good for checking whether a supplier price is normal before you list.

Cons:

• Amazon only, so AliExpress suppliers are out of scope.
• Alerts land in your inbox, and you still edit eBay yourself.

Takeaway: CamelCamelCamel replaces Keepa's charts for free, but every alert is still a manual eBay edit.

4. AutoDS: best for dropshippers who want monitoring inside a multichannel suite

Best for: dropshippers who sell on more than one channel and want price and stock monitoring bundled with importing and ordering.

AutoDS is a dropshipping platform that imports products from many suppliers and connects to several stores. Its plan list shows the Price & Stock Monitor on Starter 400 and above, sized by the number of products you import. The lowest plan, Import 200, lists a product importer without the monitor.

Key features:

• Importer with Price & Stock Monitor (400 products on Starter, 800 on Advanced).
• Automatic price optimization and AI SmartEdit on Starter.
• Unlimited store integrations from Starter.

Pricing reality: Import 200 is $26.90/month without the monitor. Starter 400 is $49.90/month and Advanced 800 is $86.90/month, each with the monitor. Auto ordering is a paid add-on on the AutoDS pricing page.

Pros:

• Monitoring, importing and ordering in one account.
• Works across several sales channels.

Cons:

• Monitoring is capped by product count, so a growing store moves up plans.
• The entry plan has no monitor at all.

If you are weighing AutoDS itself, our AutoDS alternatives comparison covers it in more depth.

Takeaway: AutoDS acts on supplier changes too, but its monitor starts at $49.90/month and counts products, where Ecomli counts monthly imports and leaves active listings unlimited.

5. Seller Assistant: best for Amazon arbitrage and wholesale sourcing checks

Best for: sellers who source by scanning Amazon listings and supplier price lists and want profit and IP checks in one extension.

Seller Assistant is an Amazon seller toolkit built around a Chrome extension. Its pricing page describes "everything you need to source, analyze, reprice and reorder profitably", and lists IP-Alert and a Price List Analyzer. The page states 45k+ extension users.

Key features:

• Extension with Amazon product data on the product page.
• IP-Alert for potential intellectual property claims.
• Price List Analyzer for supplier spreadsheets on higher plans.

Pricing reality: Pro is $29.99/month billed monthly, Business is $79.99/month and Business Plus is $189.99/month, with cheaper yearly billing.

Pros:

• Strong sourcing checks for Amazon products.
• Restriction and IP checks before you buy stock.

Cons:

• Built for selling on Amazon, not on eBay.
• It never changes an eBay listing.

Takeaway: Seller Assistant is a sourcing analyst for Amazon, useful when you buy inventory, not when you need eBay listings to follow a supplier.

6. SmartScout: best for Amazon brand and category research

Best for: sellers studying which Amazon brands, categories and sellers are growing before choosing products.

SmartScout appears in the related searches for Keepa because it answers a bigger research question: who sells what on Amazon, and how much. Its pricing page lists three plans, and each one describes the level of data access you get.

Key features:

• Brand, category and seller research for Amazon.
• Extra users at $49 each on its pricing page.

Pricing reality: Basic is $49/month, Essentials $119/month and Business $299/month when billed monthly. Billed yearly they work out to $29, $99 and $239 a month.

Pros:

• Wide view of the Amazon market for product ideas.
• Clear plan steps.

Cons:

• No eBay data and no listing actions.
• More research than most dropshippers need for supplier tracking.

Takeaway: SmartScout widens your Amazon research, but it does not track your eBay supplier prices for you.

7. Helium 10: best for Amazon brand owners who want one large suite

Best for: sellers building a brand on Amazon who want product research, keyword tools and price history under one login.

Helium 10 is a large Amazon seller suite. Its Black Box product finder checks Best Sellers Rank, sales and price history with filters, so it covers much of what sellers use Keepa for, plus keyword and listing tools for Amazon.

Key features:

• Black Box product research with sales and price history.
• Keyword and listing tools for Amazon.
• Add-ons such as a market tracker.

Pricing reality: Platinum is $129/month billed monthly ($99/month billed yearly), Diamond is $359/month billed monthly ($279/month billed yearly), and Enterprise starts at $1499/month.

Pros:

• Deep Amazon research in one place.

Cons:

• The most expensive option here, and built for Amazon selling.
• No eBay listing actions.

Takeaway: Helium 10 is a full Amazon suite that happens to include price history, priced for brands rather than eBay dropshippers.

What each Keepa alternative costs for 12 months

Monthly prices hide how much a tool costs over a year. The table puts each entry plan on one basis: the monthly price billed monthly, times 12. Yearly billing is cheaper for SmartScout, Seller Assistant and Helium 10.

How we ranked these Keepa alternatives

The order follows one question: how much of an eBay seller's price work does the tool take off your plate? A tool that changes the eBay listing ranks above a tool that only alerts you, and a tool that alerts you ranks above one that only shows data.

1. Acts on the listing. Ecomli and AutoDS both update listings. Ecomli ranks first because it is built for eBay alone, covers Amazon and AliExpress suppliers, and includes monitoring on its $29 plan with unlimited active listings.
2. Uses eBay's own numbers. eBay Product research is next because sold prices on eBay are the other half of any repricing decision, and it is free.
3. Free Amazon history. CamelCamelCamel replaces Keepa's charts at no cost.
4. Bundled monitoring. AutoDS ranks fourth: it acts on changes, but its monitor starts on a higher plan and counts products.
5. Amazon-first research. Seller Assistant, SmartScout and Helium 10 follow in order of entry price, since all three serve Amazon sellers first.

We did not test or invent results for any tool. Features and prices come from each vendor's page, and eBay facts come from eBay's help pages listed under Sources.

A worked example: one supplier price change, one listing

Here is what the "acts on the listing" job means in numbers. The figures are an illustration, not a real product: a supplier item at $20.00 and a 30% markup rule.

With Keepa or CamelCamelCamel you would see the $3.00 rise on a chart or in an email, then edit the eBay price yourself. With Stock Monitoring the markup rule reprices the listing to $29.90, and the out-of-stock rule handles the sell-out. Half of the original $6.00 gap disappears on the first price change if the listing is left alone, and eBay fees still come out of what remains.

For the margin side of this, see how eBay dropshipping profit margins work once fees are included, and how to control out-of-stock listings on eBay.

How to do this in Ecomli

Setting up supplier price tracking in Ecomli takes a few settings, after which the checks run in your browser. Here is the short version.

1. Install the Ecomli extension in desktop Chrome and sign in to your eBay seller account in the same browser.
2. Create listings from Amazon or AliExpress links with Create Listings, or bring existing listings in through Migration from AutoDS, EcomSniper or an eBay Active Listings CSV, so each listing is mapped to its supplier.
3. Open Stock Monitoring and set your markup, your out-of-stock rule (quantity 0 or end the listing), a restock quantity and a price-change tolerance.
4. Keep the browser open while you work. Ecomli checks supplier prices and stock for your listings and applies your rules, and a supplier page it cannot read leaves the listing unchanged.
5. Check the Overview dashboard to see recorded profit by day or period as prices move.

Stock Monitoring is included on every plan, so you can compare Starter, Pro and Scale by import allowance alone.

Which Keepa alternative fits how you sell

• You dropship on eBay from Amazon or AliExpress: Ecomli, with eBay Product research for sold prices.
• You only need to check whether an Amazon price is normal: CamelCamelCamel, or keep the free Keepa extension.
• You sell on several channels from one dashboard: AutoDS on a plan that includes the monitor.
• You buy Amazon inventory to resell: Seller Assistant for sourcing checks.
• You are building an Amazon brand: SmartScout or Helium 10.

If research is the gap rather than price tracking, our hub on eBay product research tools compares the research side. Keepa also appears in our roundup of Chrome extensions for eBay sellers and in the Algopix alternatives list as a supplier price-history tool, and arbitrage sellers can compare online arbitrage tools for eBay.

Frequently asked questions

What is the best Keepa alternative for eBay sellers?

Ecomli is our pick for eBay dropshippers, because its Stock Monitoring updates the eBay price and quantity, or ends the listing, when the Amazon or AliExpress supplier changes. Ecomli makes it, so weigh that. For a free option, combine eBay Product research for sold prices with CamelCamelCamel for Amazon price history.

Is there a free alternative to Keepa?

Yes. CamelCamelCamel is a free Amazon price tracker with price history charts and target-price email alerts. eBay Product research is free in Seller Hub and shows up to 3 years of eBay sales data, which Keepa does not cover.

What does the Keepa extension do?

The Keepa extension adds price history charts to Amazon product pages and lets you set alerts for price drops, according to its Chrome Web Store listing. It works on supported Amazon sites only and does not read or change eBay listings.

Does Keepa work for eBay?

Not directly. Keepa tracks Amazon prices, so eBay sellers use it to watch an Amazon supplier and then edit the eBay listing by hand. For eBay sold prices use eBay Product research, and to update listings when a supplier changes use a monitor such as Ecomli's Stock Monitoring.

Is CamelCamelCamel better than Keepa?

They do the same core job: Amazon price history and price alerts. CamelCamelCamel is free and simpler. Keepa shows its charts on the Amazon page itself through its extension. Neither one changes an eBay listing.

Can I track AliExpress prices like Keepa?

Keepa and CamelCamelCamel cover Amazon only. Ecomli's Stock Monitoring checks AliExpress suppliers as well as Amazon for the listings it manages, and AutoDS monitors supplier prices on its monitor plans.

Does Ecomli show price history charts?

No. Ecomli does not draw price history charts. It checks the current supplier price and stock for your Ecomli listings and applies your rules, and its Overview dashboard shows recorded profit by day or period.

How often does Ecomli check supplier prices?

Ecomli does not publish a fixed check interval. Stock Monitoring runs in your desktop browser while it is open, and a supplier page it cannot read leaves the listing as it was rather than ending it.

Is Keepa an Amazon price tracker only?

Yes. Keepa describes itself as an Amazon price tracker that tracks over 7 billion Amazon products. Sellers who source from AliExpress or need eBay data use other tools alongside it or instead of it.

The bottom line

Keepa is a good Amazon price tracker, and CamelCamelCamel gives you the same charts for free. For an eBay store the useful question is what happens after the price moves. Ecomli's Stock Monitoring updates the eBay price and quantity, or ends the listing, by your rules, and Product Hunting with Create Listings puts supplier-linked items in your store to begin with. Use eBay Product research next to it for sold prices.

Every plan includes Product Hunting, AI listing tools, Stock Monitoring, Safety Shield, Tracking Conversions and the profit dashboard, with unlimited active listings. Compare Starter, Pro and Scale → Monthly billing in USD · First Sale Guarantee.
