1. What each tool actually shows
| Tool | Core data | Best for |
|---|---|---|
| SellerSprite | Reverse ASIN keyword lookup, niche database, competitor tracking, browser plugin | Amazon keyword & competitor research |
| Keepa | Long-range price & sales-rank history, deal alerts | Judging price stability and seasonality |
| Kalodata | TikTok Shop sales, creator and live-stream analytics | TikTok Shop product & creator discovery |
| FastMoss | TikTok Shop trending products, videos and influencers | TikTok Shop trend spotting |
2. How to choose
- Doing Amazon seriously: SellerSprite + Keepa is a strong pair — SellerSprite for keywords/competitors, Keepa for price & rank history.
- Selling on TikTok Shop: add Kalodata or FastMoss to read short-video and live-commerce data Amazon tools don't cover.
- Validating demand: cross-check a niche with Google Trends (search interest over time) before committing.
3. SellerSprite discount codes (active)
SellerSprite runs partner referral codes that apply at checkout and work for both new purchases and renewals. Prices vary with promotions — the table shows common tiers; confirm on the official pricing page.
| Code | Plan | Discount | Typical price | Who |
|---|---|---|---|---|
| MC90 | Monthly (any plan) | 10% off | ~¥332/month | Try-it-out, tight budget |
| MC72 | Single-user annual | 28% off | ¥1928/year | Solo seller, lowest annual cost |
| MC78 | Standard & above, annual | 22% off | ¥3445/3 seats, ¥6534/6, ¥9342/10 | Small teams |
Enter the code in the "Coupon" field on the SellerSprite checkout page and click "Check validity". It works for new purchases and renewals alike.
4. Beginner pitfalls
- Buying an annual plan before you've decided what to sell — start monthly if unsure.
- Forgetting to apply the code at renewal and paying full price.
- Relying on one tool's numbers; triangulate with at least two sources.
