Helium 10 Xray Alternative: Free Tools That Estimate Sales
The best free Helium 10 Xray alternatives for Amazon sales estimation. Chrome extensions and web tools that pull BSR, revenue, and listing data from the SERP.
Helium 10 Xray costs $39 to $279 per month depending on your plan, and for a lot of sellers it’s the single feature keeping them subscribed. If all you need is the SERP overlay with BSR, estimated sales, and revenue, there’s a cheaper path. A free Helium 10 Xray alternative, or a combination of them, covers the same workflow without the subscription.
Below: which free Chrome extensions replicate Xray’s sales estimation, how they compare on accuracy and daily limits, and where the free tier breaks down enough that paying actually makes sense.
What does Helium 10 Xray actually do?
Xray is a Chrome extension that overlays Amazon’s search results page with product data. When you search a term like “resistance bands,” Xray shows a table with each listing’s BSR, estimated monthly sales, estimated revenue, price, review count, review velocity, and seller type (FBA, FBM, or Amazon).
That’s the whole product. It’s a BSR-to-sales translator with a few extra columns, rendered as a nice overlay. Everything else Helium 10 sells, Cerebro, Magnet, Scribbles, Frankenstein, lives in the web dashboard. If you’ve been using the Helium 10 Chrome extension alternative tools, you already know Xray is one slice of a much larger suite.
The sales estimate is the valuable part. Amazon doesn’t publish sales numbers, so every tool reverse-engineers them from BSR using category-specific sales curves. Amazon publishes BSR openly, which you can read about in Amazon’s Best Sellers Rank documentation on Seller Central. The translation from BSR to monthly units is where vendors differentiate, and in practice the gap between the top tools is smaller than their marketing suggests.
Any Helium 10 Xray alternative has to replicate three things: the SERP overlay format, a BSR-to-sales estimate, and basic listing metadata (price, reviews, seller). Nothing else really matters for the Xray use case.
Which free Chrome extensions replace Xray?
Three free Chrome extensions cover most of Xray’s job. Here’s how they stack up on the features that actually matter for product research.
| Tool | Free Daily ASIN Lookups | SERP Overlay | Sales Estimate | BSR History | Keyword Data |
|---|---|---|---|---|---|
| Keywords.am (reverse ASIN) | Unlimited free tier | No (web-based) | No | No | Yes |
| AMZScout Free Extension | ~10 per day | Yes | Yes | Limited | Limited |
| Jungle Scout Free Estimator | Unlimited (web form) | No | Yes | No | No |
| SellerApp Free Extension | ~5-10 per day | Yes | Yes | No | Limited |
| Helium 10 Xray (free trial) | 20 lifetime | Yes | Yes | Yes | Yes |
AMZScout’s free Chrome extension is the closest direct Xray replacement. It overlays BSR, sales estimate, revenue, price, and review count on the Amazon SERP, same as Xray. The daily lookup limit is tight, around 10 ASINs, so it’s a browse-and-decide tool, not a batch research tool.
Jungle Scout’s free sales estimator is web-based, which means you paste an ASIN or category plus BSR into a form and get back a monthly units estimate. No overlay, no SERP integration, but unlimited lookups and no account needed. It’s the simplest option if you only need the number occasionally. Walk through the mechanics in our guide to the Amazon sales estimator to see how BSR-to-sales math works under the hood.
SellerApp’s extension is similar to AMZScout but with a lower daily cap. The sales estimates are directionally close to Xray and Jungle Scout in most categories. For a wider lens on which Helium 10 alternatives suit different seller profiles, we’ve broken down the full landscape in a separate post.
How accurate are free Amazon sales estimators?
Here’s the thing most “best Xray alternative” articles get wrong: BSR-based sales estimators are all working from the same public signal. Amazon publishes BSR, each vendor builds its own category sales curve from either scraped data or seller-reported sales, and the output is a projection, not a measurement.
Published head-to-head accuracy testing is thin. The most frequently cited public comparison is Jungle Scout’s own 2017 accuracy study, which naturally reports Jungle Scout as the most accurate. Vendor-published tests should be read as marketing, not as independent benchmarks. Treat any single estimate as a rough order of magnitude.
What this means practically: don’t pay for a tool because its vendor claims better accuracy. The free tier of any major sales estimator is accurate enough for the “is this product worth researching further” decision. If you need exact numbers for a seven-figure sourcing decision, no public estimator (free or paid) is the right source. You’d want actual sales data from a supplier or a brand you’re acquiring.
The real accuracy problem is category edge cases: tiny subcategories with few data points, seasonal products, variations that split BSR across parent and child listings. All estimators struggle there, free and paid alike. Our deeper write-up on Amazon competitor analysis covers how to triangulate when a single estimate feels off.
What’s the full free stack that replaces Helium 10?
If you’re trying to replace the whole Helium 10 subscription with free tools, the stack looks like this:
- AMZScout free extension or Jungle Scout free estimator. Replaces Xray for SERP-level sales and revenue data.
- Keywords.am free reverse ASIN lookup. Replaces Cerebro for pulling keywords competitors rank for. The reverse ASIN lookup explained guide walks through the workflow.
- Keywords.am free keyword research. Replaces Magnet for seed-keyword expansion. If you specifically want a Magnet alternative, we’ve covered that in detail.
- Keywords.am rank tracker (free tier). Replaces Helium 10’s Keyword Tracker. Compared head-to-head in our rank tracker roundup.
- Keepa browser extension (free tier). Replaces Helium 10’s BSR history and price history views.
- Amazon Brand Analytics (free for Brand Registry sellers). Replaces Helium 10’s Search Query Performance data. See Amazon Brand Registry for the enrollment requirement.
- Helium 10 Chrome extension free trial (20 lifetime lookups). For the rare one-off Xray-style lookup when you want the real thing.
That stack covers sales estimation, BSR tracking, keyword research, reverse ASIN, and rank tracking. It costs zero dollars versus Helium 10’s $39 to $279 per month. What you give up is the single-dashboard experience and the one-click handoff between modules.
If you want a dedicated Cerebro alternative for the reverse ASIN side specifically, that’s a cleaner swap than trying to replicate the whole suite. Our non-technical seller keyword tools breakdown has more on which free options have the lowest learning curve.
When should you pay instead of stacking free tools?
Free stacks work for a specific profile of seller. They break down for others.
Free tools make sense if you’re researching fewer than 15 to 20 ASINs per day on average, running one to five of your own listings, and comfortable toggling between a couple of browser tabs. The math is straightforward: AMZScout’s free tier caps at around 10 ASIN lookups per day, so once your daily research volume exceeds that cap on a regular basis, you’re hitting walls that break your flow.
Paid tools make sense when you’re:
- Doing serious product research (hunting 50+ ASINs per day during active research sprints)
- Managing 10+ listings and need rank tracking at scale
- Running PPC and need ACoS and TACoS analytics integrated with keyword data
- Pulling search volume data for keyword prioritization across hundreds of terms
For sellers in that bucket, Helium 10’s Platinum plan at $79/month is often cheaper than stacking three or four paid alternatives. But the “I need Xray” seller who’s mostly browsing the SERP during product research? Free alternatives cover that cleanly. Our AI tools for Amazon sellers guide covers a broader set of options at different price points.
The other case for paying: international sellers. Free Chrome extensions tend to cover amazon.com and a handful of EU marketplaces. If you’re selling across six or more marketplaces, paid tools pull ahead. Our international expansion tooling post covers which tools handle multi-marketplace cleanly.
How does Keywords.am fit into the free alternative stack?
Keywords.am covers the keyword and ranking side of what Helium 10 does, not the sales estimation side. We don’t try to replicate Xray’s SERP overlay or BSR-to-sales math, that’s a different problem with free tools (AMZScout, Jungle Scout) already solving it well.
What we handle: reverse ASIN lookup, keyword research, SERP position tracking, listing optimization scoring, and the TFSD methodology for structuring listings. If you’ve read our take on keyword research methodology you already know where our focus is.
Honest scope limits: no product research module (we don’t try to be a Jungle Scout competitor), no PPC automation (use Amazon’s console or a dedicated PPC tool), no sales estimator (free tools cover this). The scope is deliberate. Doing one thing well beats a mediocre version of ten features.
For sellers building a free alternative stack, the practical pairing is a free Chrome extension for product browsing (AMZScout or Jungle Scout’s free estimator) plus Keywords.am for the keyword and ranking work. That covers Xray’s job and most of Cerebro’s job for free. Our full Helium 10 vs free alternatives hub has more context on the tradeoffs.
Want the quick version? Run your first free reverse ASIN lookup on Keywords.am and see how much of Cerebro’s job the free tier covers before you commit to a paid tool.
Frequently Asked Questions About Helium 10 Xray Alternatives
Is there a free Chrome extension that works exactly like Xray?
AMZScout’s free Chrome extension is the closest direct replacement for Xray’s SERP overlay. It pulls BSR, estimated sales, revenue, price, and review count onto the Amazon search results page the same way Xray does. The free tier caps at roughly 10 ASIN lookups per day, which is the main constraint.
How does Keywords.am compare to Helium 10 Xray?
Keywords.am and Xray solve different problems. Xray estimates sales from BSR on the SERP. Keywords.am does reverse ASIN keyword research, rank tracking, and listing optimization. If you’re trying to replace all of Helium 10 for free, you’d pair Keywords.am with a free sales estimator extension like AMZScout or Jungle Scout’s free tool.
Are free Amazon sales estimators accurate enough for product research?
For go/no-go decisions on whether a product is worth researching further, yes. All BSR-based estimators work from the same public signal and produce results in the same ballpark. For precise forecasting or seven-figure sourcing decisions, no public estimator (free or paid) is reliable enough. You’d want actual supplier or brand data.
What’s the catch with free Chrome extensions?
Daily lookup caps. Most free extensions limit you to 10 to 50 ASIN lookups per day before gating further use. For light research that’s fine. For sellers who research 50+ ASINs daily during active sourcing sprints, the free tier becomes a bottleneck fast.
Can I just use Helium 10’s free trial instead of alternatives?
Helium 10’s free Xray tier gives you 20 lifetime lookups, not 20 per day. That’s one afternoon of research and then you’re paying. The free trial is useful for seeing what Xray feels like, not for ongoing use. Free Chrome extensions from other vendors give you more sustainable free access.
Free alternatives to Helium 10 Xray cover the sales estimation workflow cleanly for most sellers. The real question isn’t whether a free tool can replace Xray (it can), it’s whether you need the integrated suite experience that Helium 10 charges for. For sellers researching casually or running a small catalog, the free stack holds up. For heavy daily researchers managing dozens of listings, paid tools eventually pay for themselves.
