Product research tools answer one question: what are people already buying? Instead of guessing, you start from products with proven demand and decide whether you can sell them better.
Here are the best options in 2026 for Shopify, TikTok Shop and Amazon sellers, including the free ones.

Kalodata: the TikTok Shop specialist
Kalodata tracks sales on TikTok Shop: which products sell most, which shops sell them, and which creators drive the sales. You can filter by category, region and date range to spot products that are climbing.
Best for: anyone selling on TikTok Shop, or planning to.
Watch out for: lower plans cap how many results you see, so deep research usually needs a higher tier.
WinningHunter: start from what's trending in ads
WinningHunter surfaces products that are getting traction in ads and stores right now, along with the ads and stores selling them. It's built for dropshippers who haven't picked a product yet.
Best for: beginners choosing their first product.
ShopHunter: see what competitors actually sell
ShopHunter tracks sales activity at Shopify stores. Point it at a competitor and you can see which of their products move, which is often more useful than guessing from their homepage.
Best for: sellers who already have competitors in mind.
SellerSprite: the Amazon pick
SellerSprite covers Amazon product research and keyword research: sales estimates, keyword search volume and competition. If Amazon is your channel, it's a better fit than the TikTok- and Shopify-focused tools above.
Best for: Amazon FBA and marketplace sellers.
ExplodingTopics: find the niche first
ExplodingTopics isn't a product database. It shows search topics that are growing fast, which helps you pick a niche before it gets crowded. Use it before the other tools, not instead of them.
The free options are better than you'd think
- TikTok Creative Center: top ads, trending products, hashtags and songs on TikTok
- Amazon Best Sellers and Movers & Shakers: what's selling and what's climbing on Amazon right now
- Google Trends: whether interest in a product is growing, flat or falling
For your first product, these may be all you need. Paid tools add sales estimates, filters and history, which matter more once you're testing products every week.
Which one should you pick?
- Selling on TikTok Shop? Kalodata, plus TikTok Creative Center.
- Dropshipping on Shopify? WinningHunter to find products, ShopHunter to study competitors.
- Selling on Amazon? SellerSprite.
- Still choosing a niche? ExplodingTopics and Google Trends first.
Most sellers end up wanting two or three of these. For the full process of using them together, read How to find winning products with spy tools.
