Yes: the SellerSprite Chrome extension is free to install, and its core tier stays free permanently. You only pay for deeper data and uncapped lookups, which arrive with paid plans from $39/mo billed monthly. Casual product hunters can stay on the free tier indefinitely.
I checked the Chrome Web Store listing before writing this guide. It carries Google's Featured badge and holds 4.4 stars across 521 ratings.
- Install cost: $0 on Chrome, Edge, or Firefox.
- Free tier: Free forever, with usage caps.
- Full data: Paid plans from $39/mo billed monthly.
- User base: 500,000 users on Chrome alone.
- Bonus: Profit, AmzSave, and PricePal install free too.
SellerSprite's extension page installs free to Chrome or Edge and lists the three free companion extensions (Profit, AmzSave, and PricePal) alongside the main tool.
What the SellerSprite Chrome Extension Actually Does
The SellerSprite Chrome extension overlays research data directly on Amazon search results and product pages. It pulls from a live database SellerSprite says holds 20M+ product records. SellerSprite also claims the extension mirrors about 80% of its web app. My full SellerSprite review scores that web app 4.1 out of 5.
The overlays follow you across SellerSprite's 9 supported Amazon marketplaces: the US, UK, Germany, France, Italy, Spain, Japan, India, and Canada. Search results pages, Best Sellers pages, and individual product pages each trigger different panels. Three of those panels do most of the work.
Product Quick View on Search Pages
Product Quick View injects a data strip under every listing on an Amazon search page. Five fields load per product: estimated sales, seller count, FBA or FBM, variation count, and first published date. Listing age alone separates an entrenched competitor from a product that climbed fast.
Operator scenario: Say you search "collagen gummies" and every top listing shows 4,000+ estimated monthly units. Quick View also shows 20+ sellers on half the listings. That combination reads as high demand with brutal competition. You just disqualified the niche in two minutes, before opening a single product page.
The strip also splits FBA from FBM sellers at a glance. A results page stacked with FBA offers usually means tighter price competition. An FBM-heavy page can signal room for a faster Prime offer.
Category Insights: 26+ Dimension Market Reports
Category Insights builds a market report with 26+ dimensions from any Amazon Search Results or Best Sellers page. One click turns a browsing session into a demand study. The report covers the market-level view most extensions skip. It runs inside the browser, not the web app.
Operator scenario: Say you shortlist the Kitchen category for a Q4 launch. From the Best Sellers page, one click builds a report scoring the market across 26+ dimensions. If a few brands soak up most sales, you walk away before paying for samples.
That aggregation is the reason to install this over lighter rivals. Most free extensions stop at per-product stats. Very few roll an entire results page into one market report.
Keyword Data and Keepa-Style Trend Charts
The extension embeds Keepa-style price and BSR trend charts directly on Amazon product pages. SellerSprite even titles the feature Keepa Trends in its help guides. For context, full Keepa access runs €29/mo. Keyword data rides in the same overlay, so you check terms and history without switching tabs.
Operator scenario: Say a supplier quotes you a product that looks great at $24.99 today. The embedded trend chart shows the price sat at $17.99 for most of the last year. That gap changes your margin math completely, and you caught it on the Amazon page itself.
Serious price-history work still belongs in a dedicated tracker. The embedded charts cover the quick sanity check, which is most of what you need mid-browse.
How to Install the SellerSprite Extension
Installation is a few clicks on any of the three supported browsers. The Chrome listing is named SellerSprite - Amazon Research Tool, weighs 8.56MiB, and ships in 3 languages. Searches for Seller Sprite, spelled as two words, land on this same one-word extension.
- Open the Chrome Web Store and find the listing named SellerSprite - Amazon Research Tool.
- Click Add to Chrome, then confirm with Add extension in the popup.
- On Microsoft Edge, click Add to Edge on SellerSprite's extension page instead. On Firefox, install SellerSprite - Amazon Tool from the Firefox add-ons library.
- Pin the icon through the browser's puzzle-piece menu so the controls stay one click away.
- Run any Amazon search to see Quick View data, then open a product page for the embedded trend charts.
If you searched for a SellerSprite download, this is it. There is no desktop installer: the extension plus the web app is the whole product.
What's Free vs What Needs a Paid Plan
The free-paid boundary is simple. Installing costs nothing, and a permanently free tier keeps working after that. Paid plans add data depth and remove caps. Every paid plan lists the extension as unlimited, with no daily cap. Paid access starts with Basic at $39/mo billed monthly.
What you get | Free extension | Paid plans (from $39/mo) |
|---|---|---|
Cost | $0 install, permanently free tier | Basic $39/mo billed monthly, $390/yr billed annually |
Extension usage | Free tier with caps | Unlimited, no daily cap |
Research suite | Free tools like the Sales Estimator | Keyword Mining, Reverse ASIN, and 5 more, all unlimited |
Extras | 3 companion extensions | 100 AI insight reports and 50 data exports per day |
Upgrading mostly changes what sits behind the extension. On any paid plan, seven web tools go unlimited alongside it: Keyword Mining, Keyword Research, Reverse ASIN, Competitor Research, Product Research, Category Insights, and Index Checker. Plan-by-plan limits, tracker slots, and the annual math live in my SellerSprite pricing breakdown.
The free entry point also beats the biggest rival's model. Jungle Scout gates its extension behind a paid plan, from $29/mo billed annually or $49 monthly. SellerSprite hands you a working free tier before ever asking for a card.
Three More Free SellerSprite Extensions
SellerSprite ships three companion extensions beyond the main research tool, and all three install free. Profit calculates margins, AmzSave downloads listing media, and PricePal matches supplier photos to Amazon listings. Most coverage skips all three, which is a miss for anyone sourcing products.
- Profit: A profitability calculator that runs on any product page. It shows net profit, margin, and break-even, using per-marketplace Amazon fee data.
- AmzSave: An images downloader. It bulk-saves main images, A+ content, review media, bullet points, and videos in their original resolution.
- PricePal: Matches a supplier's photo to identical Amazon listings, then shows price, reviews, rating, and rank signals for each match.
Say a supplier pitches you their best seller. PricePal shows every identical listing already live on Amazon, with rank and review signals attached, before you commit to an order.
Is the SellerSprite Extension Safe and Legit?
Chrome Web Store signals look healthy for an extension this size. The listing shows 500,000 users, and version 5.0.4 shipped on June 29, 2026. SellerSprite itself claims 700K+ installs across all browsers. The developer is listed as Chengdu Yunya Information Technology Co., LTD, based in Chengdu, China.
A China-based developer is a fact I would rather state plainly than bury. If that matters to your risk tolerance, you now have it upfront. The wider picture stays positive: SellerSprite's Trustpilot profile holds 4.7 stars from 34 reviews, and Trustpilot flags no recent history of the company asking customers for reviews.
The Chrome Web Store listing pairs its Featured badge with 4.4 stars from 521 ratings, 500,000 users, and a version 5.0.4 update on June 29, 2026.
Verdict: Install It, Then Let the Caps Decide
The SellerSprite Chrome extension is the rare free tool that stays useful before you pay. Install it and run it on your niche for a week. Let the caps tell you whether deeper data is worth $39/mo. Most casual product hunters never need the upgrade at all.
If you only flip retail arbitrage finds a few times a month, the free tier plus the Profit calculator covers the whole workflow. If you outgrow the caps, test before paying: the SellerSprite free trial gives you 3 days of full monthly-plan access with no credit card required. And when you commit, the SellerSprite coupon page lists deals worth up to 45% off.
