Helium 10 vs KDSPY (2026): which should you pick?

Pick Helium 10 if

• Fits if you're launching private label products and want research and profits in one account
• Works for sellers branching out from Amazon to Walmart or TikTok Shop

Look elsewhere if

• Pricey if you want ads automation or profit and loss reports, which start on Diamond at $279
• Skip it if all you need is a profit dashboard, as sellerboard starts at $15
• Tight if you're on Platinum: 20 tracked ASINs, 40 SKUs, and a forced move to Diamond past $100K a year in sales
• Watch out: Helium 10 Ads takes 2% of managed ad spend, and the refund service keeps 15% on Platinum
• Watch out: add-ons cost extra, with tracked keywords from $19 a month, MCP from $50 and Market Tracker 360 from $650

Pick KDSPY if

• Fits if you self-publish and want sales estimates for a category before you pick a book topic
• Works for authors who research while browsing Amazon and would rather pay once

Look elsewhere if

• Not for you if you want to try it first, as there's no trial or free plan, only a 60-day money-back guarantee
• Skip it if you sell anywhere but Amazon, as its data covers 13 Amazon stores and nothing else
• Watch out: it doesn't work on iPads, tablets or phones, only as an extension in a desktop browser
• Tight if you work on more than two computers, as the license covers two devices you own
• Watch out: sales and revenue figures are its own estimates, and the $79 is shown cut from a crossed-out $197 with no end date
