Helium 10 Magnet Alternative: Free & Cheaper Keyword Tools
The best Helium 10 Magnet alternatives for Amazon keyword research. Free and paid options compared on data, pricing, and features.
Helium 10 Magnet does one job well: give it a seed keyword, get back a list of related Amazon search terms with volume estimates. The problem is you can’t buy just Magnet. It’s bundled inside Helium 10’s full suite, which means paying $39 to $229 per month for product research, inventory, and PPC modules you may never touch. If keyword expansion is all you need, a Helium 10 Magnet alternative will cover the same workflow at a lower cost, and in some cases for free.
This post ranks the real options, compares what they cost against what they deliver, and flags the limitations of each so you can pick without regret.
Why do sellers look for a Helium 10 Magnet alternative?
The most common reason is pricing. Helium 10’s pricing page lists Starter at $39/month, Platinum at $99/month, and Diamond at $229/month as of 2026. Magnet is included on all tiers, but Starter caps you at a handful of Magnet searches per day. If you run keyword research daily across multiple ASINs, you’re pushed to Platinum fast.
The second reason is scope. Many sellers only need two things from a keyword tool: expand a seed term into a list, then track where their listing ranks for those terms. Helium 10 bundles 20+ tools you won’t touch. Dedicated alternatives strip the suite down to the parts you actually use. That’s why posts like best Amazon keyword research tool and Cerebro alternative keep ranking: sellers want the specific feature, not the suite.
The third reason is data freshness and marketplace coverage. Helium 10 covers all major Amazon marketplaces, which is a real strength. But for sellers focused on a single geography, cheaper tools often match Magnet’s data accuracy. For a deeper look at how cross-market tools behave, Amazon international keyword research covers the trade-offs.
Finally, there’s workflow fatigue. Switching between Magnet, Cerebro, Frankenstein, and Scribbles to build one listing is friction. Tools that collapse keyword research, listing optimization, and rank tracking into one view save real time. This is where the methodology behind Amazon keyword research matters more than the brand on the dashboard.
What should a Magnet alternative actually do?
Magnet’s core function is seed-to-list keyword expansion. You enter one or more seed terms, and the tool returns related Amazon search terms with estimated monthly search volume. That’s the baseline any alternative must match.
Beyond that, the features that matter for most sellers:
- Search volume estimates. Should be dated and sourced. For how these numbers are produced and why they vary between tools, see Amazon search volume.
- Related keyword variants. Long-tail and modifier expansions, not just synonyms.
- Marketplace selection. US, UK, DE, FR, IT, ES, JP, AU, CA at minimum.
- Export to CSV. Non-negotiable. You will build spreadsheets.
- Rank tracking integration. Finding keywords is step one; tracking rank for them is step two. The Amazon keyword rank tracker tools overview explains why bundling matters.
- Reverse ASIN lookup. Not strictly a Magnet feature (that’s Cerebro’s job), but most sellers want both in one tool. See reverse ASIN lookup explained for how it fits the research flow.
Features that are nice but not essential:
- Historical trend charts
- Keyword difficulty scoring
- CPC estimates
- Automatic grouping or clustering
If a tool nails the first six and skips the second four, it’s a working Magnet alternative for most sellers.
Which tools are the best Helium 10 Magnet alternatives?
Here’s the shortlist. All pricing is as of 2026-10-14 and pulled from each vendor’s public pricing page.
| Tool | Starting Price | Free Tier | Seed-to-List | Rank Tracking | Marketplaces |
|---|---|---|---|---|---|
| Keywords.am | $19/mo | Yes | Yes | Included | 10+ |
| Sellerapp | $39/mo | Limited | Yes | Add-on | 8 |
| Sonar (Perpetua) | Free | Yes | Yes | No | 6 |

Keywords.am
Pricing
Annual plans start at $19/month. The free Amazon keyword tool runs without an account.
Best For
Sellers who want keyword research, rank tracking, and listing optimization in one tool without paying for product research or inventory modules. This is the gap Helium 10’s bundle creates, and it’s what Keywords.am fills. For a direct feature comparison, Keywords.am vs Jungle Scout breaks down the scope difference.
Strengths
- Free tier is usable for daily research, not a 7-day trial.
- Rank tracking is bundled, not an upsell.
- Clean workflow from seed to tracked keyword in one session.
- Built-in backend keywords byte counter and product title optimization helpers.
Limitations
- No product research module. If you need something like Helium 10 Black Box or Jungle Scout Product Database, you’ll need a separate tool.
- No PPC automation. For PPC campaign management, see the Amazon PPC optimization guide and plan to run bids manually or through another tool.
- Fewer historical trend charts than Helium 10 Diamond.
Sellerapp
Pricing
$39/month on the Pro plan.
Best For
Sellers who want a lightweight version of Helium 10’s suite with PPC and listing tools in one place.
Strengths
Decent keyword expansion. Reasonable listing quality score. Good UI.
Limitations
Rank tracking is an add-on. Marketplace coverage lags behind Helium 10 and Keywords.am. Volume estimates can drift from Amazon’s own autocomplete signals.
Sonar by Perpetua
Pricing
Free, with a Perpetua account.
Best For
Occasional lookups and sellers already in the Perpetua ecosystem.
Strengths
Free. Covers 6 marketplaces. Simple interface.
Limitations
Data freshness has been inconsistent since the Perpetua acquisition. No rank tracking. No reverse ASIN. If you need something more than one-off lookups, you’ll outgrow it fast.
MerchantWords
Pricing
$35/month on the Silver plan.
Best For
Sellers who want deep historical keyword data across many marketplaces.
Strengths
Large database. 11 marketplaces. Historical trends go back further than most competitors claim.
Limitations
Volume estimates skew high in some categories. No rank tracking. UI feels dated compared to newer tools.
Jungle Scout Keyword Scout
Pricing
$49/month on the Basic plan.
Best For
Sellers already using Jungle Scout for product research who want to keep everything in one dashboard.
Strengths
Good integration with Jungle Scout’s product database. Decent accuracy. Chrome extension helps during competitor browsing.
Limitations
Expensive if you only want keyword research. Rank tracking is a separate module. See the detailed Keywords.am vs Jungle Scout breakdown for how the pricing compares.
How do the free Amazon keyword research tools compare?
Free tools have come a long way. For single-seed expansion in a US marketplace, several free options match paid Magnet output within a reasonable margin.
| Free Tool | Seed-to-List | Volume Estimates | Marketplaces | Export |
|---|---|---|---|---|
| Keywords.am Free | Yes | Yes | 10+ | CSV |
| Sonar | Yes | Yes | 6 | CSV |
| Amazon Autocomplete (manual) | Partial | No | All | Manual |
| Google Keyword Planner | Partial | Google data | N/A | CSV |
A few notes on the manual options. Amazon’s own search bar autocomplete is a legitimate free data source, straight from the horse’s mouth, but it’s slow to scrape manually. Amazon’s A9/A10 ranking signals rely on search behavior that autocomplete partially reflects, which is why so many tools build on top of it. Google Keyword Planner shows Google search volume, not Amazon, so use it only for brand or category-level directional data. The difference between Amazon SEO and Google SEO is big enough that you shouldn’t rely on Google data for Amazon decisions.
For sellers who want a free workflow that actually scales, free Amazon keyword research walks through how to combine the free tier of Keywords.am with Amazon autocomplete and ASIN scraping. The guide for non-technical sellers covers the same ground without the tech jargon.
When does it make sense to stay with Helium 10 Magnet?
Honest answer: three scenarios.
First, if you already pay for Helium 10 Platinum or Diamond for other tools like Cerebro, Black Box, Keyword Tracker, or Adtomic. Magnet comes free with the subscription. Switching just for keyword expansion is pointless.
Second, if you need historical keyword trend data going back 24+ months. Helium 10 states they maintain multi-year historical charts on Diamond. If seasonal trending for categories like holiday decor or seasonal apparel drives your buying decisions, that depth matters.
Third, if you manage 100+ ASINs and need Helium 10’s bulk operations and alerts. The suite is built for scale, and single-feature alternatives aren’t going to match that throughput.
For everyone else, which is most sellers running 1-50 ASINs, a dedicated keyword tool covers the daily workflow at a fraction of the cost. The competitor analysis workflow doesn’t require a $229/month suite.
How do you migrate your keyword workflow off Magnet?
Most sellers overestimate how long this takes. Budget 2-3 hours for a complete migration.
- Export your Magnet keyword lists. Download your saved searches and keyword groups as CSV from inside Helium 10.
- Export your tracked keywords from Keyword Tracker. If you use Helium 10’s rank tracker, pull that list too. You’ll re-import it into the new tool.
- Pick a replacement tool. Based on the comparison table above, decide between a free tier and a paid alternative.
- Re-import seed terms and ASINs. Most tools accept CSV import. Keywords.am and MerchantWords both support bulk upload.
- Rebuild tracked keyword groups. This is the slowest step. Group by product, by funnel stage, or by TFSD framework category depending on how you organize research.
- Verify rank data for 48 hours. New tools need a day or two to establish baseline ranks. Don’t make decisions off day-one data.
- Cancel Helium 10 after a 30-day overlap. Keep both running for a month to confirm the new tool matches the data you’re used to.
For sellers who want to tighten the whole research-to-listing flow during the migration, revisit the Amazon keyword research methodology and the bullet points guide to make sure the new keyword list actually makes it into the listing properly. Nothing wastes more time than researching keywords you never use.

Frequently Asked Questions About Helium 10 Magnet Alternatives
Is there a free Helium 10 Magnet alternative?
Yes. Keywords.am offers a free Amazon keyword tool that returns seed-to-list expansions and search volume estimates without a credit card. Sellerapp and Sonar also offer limited free tiers, though Sonar’s data freshness has slipped since Perpetua acquired it. For most sellers researching 1-50 ASINs, the free tier covers daily workflow.
What’s the main difference between Helium 10 Magnet and its alternatives?
Magnet is bundled inside the full Helium 10 suite, which starts around $39/month for Starter and climbs to $229/month for Diamond, per Helium 10’s pricing page. Standalone keyword tools skip the product research, inventory, and PPC modules and charge less because of it. If you only need keyword expansion and rank tracking, you’re paying for features you won’t use.
Can I replace Helium 10 Magnet with a free tool and still get accurate search volume?
For most product categories, yes. Free tools pull from the same clickstream and Amazon autocomplete sources the paid tools use. Where paid tools pull ahead is in historical trend data and massive multi-ASIN batch processing. If you’re researching under 20 keywords at a time, free is fine.
Is Helium 10 Magnet worth it compared to standalone alternatives?
Magnet is worth it if you’re already paying for Helium 10 for Cerebro, Black Box, and PPC tools. As a standalone keyword expansion tool, it’s expensive. Dedicated alternatives give you the same seed-to-list output for a fraction of the cost, and some offer features Magnet lacks like per-market rank tracking and backend keyword byte counters.
What should I look for in a Helium 10 Magnet alternative?
Three things: search volume accuracy against a known benchmark ASIN, seed-to-list breadth, and marketplace coverage. If you sell outside the US, verify marketplace coverage before committing. Also check whether rank tracking is bundled or sold separately, because that single factor often doubles the real cost.
Conclusion
- Helium 10 Magnet is bundled; standalone alternatives are usually cheaper if you don’t need the full suite.
- Keywords.am covers the keyword research plus rank tracking workflow for $19/month, with a working free tier.
- Sonar, MerchantWords, and Sellerapp each have niches, but data freshness and marketplace coverage vary.
- Free tools cover 1-50 ASIN workflows well; paid tools pay off at scale or when you need historical trends.
- Migration takes 2-3 hours. Keep both tools running for 30 days to verify data parity before cancelling.
If you’re switching away from Magnet because you don’t need Helium 10’s full suite, Keywords.am is the direct replacement. Rank tracking is included, the free tier is usable from day one, and the workflow collapses keyword research and listing optimization into a single view.
