Search "ZonBase" in the Chrome Web Store and the only result does not say ZonBase anywhere in its name. That listing, ZonResearch - Product Scanner, is the official ZonBase Chrome extension, published by Zonbase Inc., and it needs the $109 Legendary plan (or the Legendary trial) before it shows data.
The listing itself is small but healthy: 4.9 stars across 67 reviews, about 4,000 users, and an update shipped in July 2026.
Key Takeaways
- Store name: search "ZonResearch - Product Scanner" in the Chrome Web Store, not "ZonBase."
- No free version: the extension needs the $109 Legendary plan; the $49 Standard plan excludes it.
- Trial catch: on the 7-day free trial, ZonBase's own FAQ says to pick the Legendary plan for extension access.
- What you get: page-one revenue averages, per-product sales estimates, 12-month trends, keyword data, and a profit calculator.
- Scale check: about 4,000 users versus 1,000,000 on Helium 10's extension.
What Is the ZonBase Chrome Extension?
The ZonBase Chrome extension is an on-page research overlay for Amazon, included with ZonBase's Legendary and Diamond plans ($109 and $299 a month). The Chrome Web Store lists it as ZonResearch - Product Scanner: version 14.0.11, updated July 2, 2026, about 4,000 users, and a 4.9-star rating from 67 reviews.
The "offered by" line says Digital Ninjaz, which looks odd until you open the developer details: Zonbase Inc., the company behind the suite. Same outfit, different label.
The Chrome Web Store listing: 4.9 stars from 67 ratings and about 4,000 users. Search "ZonResearch" to find it.
Here's what it actually puts on your screen.
What the ZonBase Chrome Extension Shows You
The extension works in two places: Amazon search results and individual product pages. On a results page, it overlays keyword stats and page-one averages. On a product page, it opens a widget with sales estimates, rank history, and a profit calculator. ZonBase fetches the data live from Amazon while you watch.
Search-Page Stats and Page-One Averages
Run any Amazon search and the overlay reports the keyword's estimated search volume, a Smart Score, and a CPC range, plus four page-one averages: monthly revenue, monthly units sold, unit price, and review count. ZonBase's own "basketball" demo shows 21,474 estimated searches and a $63,760 average monthly revenue.
Smart Score is ZonBase's demand-to-competition ratio: how often a keyword gets searched against how many listings compete for it.
The overlay on ZonBase's "basketball" demo: 21,474 estimated searches, page-one averages of $63,760 monthly revenue and 4,424 reviews, plus Export CSV and Column Settings on the product table.
Operator scenario: Say your bar is $5,000 monthly revenue with under 300 reviews. The overlay's counters answer that in one glance: the demo screen shows 10 products clearing $3,000 in revenue and zero under 300 reviews. That keyword fails your second filter, and you move on without opening a single listing.
12-Month Sales History and Trends
The Trends tab charts the past 12 months of sales for the whole results page, then adds three seasonal reads: average price over the last 90 days, best selling months, and the rate of review growth. For basketball, ZonBase's demo flags August and December as peak months and pegs review growth at 241.4 a month.
That review-growth number matters more than it looks. A niche adding 241 reviews a month per page-one product is brutal to enter late.
The Trends tab for the same search: a 12-month sales curve, August and December flagged as the best selling months, and reviews growing at 241.4 a month.
Operator scenario: If you source a seasonal product in March with a 60-day lead time, the sales curve tells you whether your inventory lands into the August peak or after it. Miss that window and you hold stock through the slowest quarter on the chart.
The Product-Page Widget and Profit Calculator
On a product page, the widget's Quick Info card shows the ASIN, BSR, estimated monthly sales, and estimated revenue, with expandable sections for Rank & Prices, Alerts, Charts, Offers, and a Profit Calculator. The calculator splits FBA and FBM and itemizes manufacturing cost, freight, and Amazon fees.
In ZonBase's demo, a $20 product carries a $13.67 FBA fee once dimensions and weight are loaded in. That math is the difference between a margin and a donation.
The product-page widget and Profitability Calculator: FBA versus FBM tabs, a $13.67 FBA fee on a $20 item, and supplier links out to Alibaba.
Operator scenario: Say you're validating a $22 kitchen product with a $4.20 unit cost. Load your real freight quote into the calculator and watch the fee line: if Amazon fees plus landed cost cross $15, you're under a 30% margin before ads, and the product needs a higher price point to work.
Keyword Data for Every Product
The extension also reverses any single product into its top-ranking keywords, each with search volume, Smart Score, and a CPC range ($1.06 to $2.32 in the demo). It's a lighter take on a reverse-ASIN lookup, and the CPC column previews what Sponsored Products clicks would cost you in that niche.
One caution before you lean on the numbers. In ZonBase's own store screenshot below, the Search Volume and Smart Score columns repeat the product's $23,645.46 revenue figure on every row. That's a bug in their demo image rather than proof the live tool misfires, but treat every figure as an estimate. ZonBase's own FAQ says the numbers are not guaranteed.
ZonBase's own Chrome Web Store screenshot repeats the $23,645.46 revenue figure in the Search Volume and Smart Score columns (boxed in red). Treat demo numbers as illustrations, not data.
Operator scenario: You find a competitor doing an estimated 1,154 units a month. Pull its top keywords, note the two with the highest Smart Score, and run both back through the search overlay. If page-one averages clear your revenue bar from that second angle too, the niche survives the check.
Installing it takes about two minutes. The account is the real gate.
How to Install the ZonBase Chrome Extension
Installation is a standard Chrome flow with one prerequisite: a ZonBase account on the Legendary plan or above, because the $49 Standard plan does not include the extension. The install itself takes about two minutes, and ZonBase's help center walks the same steps with a 90-second video.
- Create a ZonBase account. My 7-day free trial walkthrough covers the signup flow and the card requirement.
- Open the ZonResearch - Product Scanner listing in the Chrome Web Store, or search "ZonResearch" inside the store.
- Click "Add to Chrome," then "Add extension" in the confirmation prompt.
- Pin the extension: click the puzzle-piece icon in Chrome's toolbar, then the pin next to ZonResearch.
- Log in with your ZonBase credentials when the extension asks.
- Go to Amazon, run a product search, and click the pinned icon to load the overlay.
ZonBase Chrome Extension Pricing and Daily Limits
The Chrome extension needs ZonBase's $109 Legendary plan; the $49 Standard plan does not include it. ZonBase's pricing page marks the extension with a gray cross on Standard, the same mark ZonPPC gets. Annual billing cuts 24% to 33%. Legendary caps the extension at 250 uses a day, Diamond at 1,000.
Plan | Monthly price | Annual price | Chrome extension access |
|---|---|---|---|
Standard | $49/mo | $399/yr | Not included |
Legendary | $109/mo | $999/yr | 250 uses per day |
Diamond | $299/mo | $2,399/yr | 1,000 uses per day |
Two fine-print items matter. ZonBase's extension FAQ tells trial users to pick the Legendary plan if they want to test the extension during the 7-day window. And every plan carries a separate 7-day money-back guarantee, so a billed first week is not a locked-in month. The full plan-by-plan math sits in my ZonBase pricing breakdown.
So how does it stack up against the extensions everyone actually installs?
ZonBase vs Helium 10 vs Jungle Scout Extensions
The Chrome Web Store tells the market-share story plainly. ZonResearch serves about 4,000 users. Helium 10's extension serves 1,000,000 and Jungle Scout's 300,000. Ratings run the other way: 4.9 stars for ZonResearch against 4.1 and 3.8, though 67 reviews is a small sample that tends to rate kindly.
Extension | Chrome users | Store rating | Ratings count |
|---|---|---|---|
ZonResearch (ZonBase) | 4,000 | 4.9 | 67 |
Helium 10 | 1,000,000 | 4.1 | 769 |
Jungle Scout | 300,000 | 3.8 | 369 |
AMZScout PRO | 100,000 | 4.6 | 878 |
All four counts come straight from the Chrome Web Store as of July 2026.
- Stay with ZonBase if you already pay for Legendary or Diamond. On those tiers the extension adds page-one math at no extra cost.
- Pick Helium 10 if you want the deepest extension on the market. My Helium 10 extension guide covers its niche stats, stock levels, and review analysis.
- Pick Jungle Scout if you want a budget-friendly suite with a long accuracy track record. The Jungle Scout extension walkthrough shows the install and what its overlay reports.
Verdict: Worth Installing?
Worth installing, rarely worth subscribing for. If you already run ZonBase on Legendary or Diamond, add the extension today: it turns page-one math into a one-click check. But nobody should start a $109-a-month plan for the extension alone while Helium 10 and Jungle Scout ship stronger extensions backed by far larger user bases.
- Install it if: you're on Legendary or Diamond already, or you're testing the suite on the Legendary trial anyway.
- Skip it if: you're choosing your first research toolkit. My full ZonBase review lands at 2.8 stars and explains where the suite trails its rivals.
- Budget angle: the extension's real cost is the plan behind it: $109 a month minimum, because the $49 Standard plan locks it out.
If you want to test it anyway, the 7-day Legendary trial covers the extension: run your product ideas through the overlay and cancel inside the window if the numbers don't convince you.
Building your research stack from scratch instead? Start with the Helium 10 platform if you want the deepest toolkit on the market, or SmartScout if market and brand intelligence matters more to you than keyword volume.
