eBay seller tools compared
The right tool depends on where you sell and what slows you down. Here is what Tyasi, eBay's own Seller Hub and Product Research, and five outside tools do, what they cost as listed on their own pages, and when each one is the better pick.
We make Tyasi, so read this with that in mind. Every fact about another tool links to that company's own page with the date we checked it (November 3, 2026). Prices and features change; check the linked page before you buy. Where another tool is the better fit, we say so.
The short version
- You sell on several marketplaces: a crosslister (Vendoo, List Perfectly, Crosslist or Flyp) fits better. Tyasi is built only for eBay.
- You mainly want eBay's sold data: Product Research, inside Seller Hub, is eBay's own and looks back up to three years.
- You want dedicated product and competitor research: ZIK Analytics is built for it.
- You sell mostly on eBay and want sourcing, listing, pricing rules, orders and profit in one place: that is what Tyasi is for.

Tyasi
Tyasi is a workspace for eBay sellers, available now on the web at tyasiapp.app. It connects through eBay's own sign-in and has no access to your payouts. The features page shows each part working.
- Find: search eBay and results get a Deal Score from recent sold prices (a result with no sold prices stays unscored), with estimated profit, margin and days to sell; Scan & Go prices an item from a photo.
- List: a listing drafted from one photo, which you check and publish; templates, drafts and scheduled listings.
- Manage and ship: inventory with cost and margin, orders, buyer messages, returns and labels bought on your own Shippo or EasyPost account.
- Price and promote: strategies are rules you set, run in one click or on a schedule, never below your margin floor, with every change logged (Operator and Business); Promoted Listings and discounts (Operator and Business).
- See what it made: profit, margin and aging reports, with exports your accountant can use.
| Plan | Price a month | eBay stores | Team seats | Adds |
|---|---|---|---|---|
| Solo | $29 | 1 | None | Sourcing, listing from a photo, inventory, orders and labels, basic analytics, Ask Tyasi |
| Operator | $69 | 3 | 2 | Strategies, Groups, Promotions, the Daily Briefing, bulk listing and Team |
| Business | $179 | 5 | 5 | The full P&L, forecasts and stores compared side by side |
What Tyasi does not do: it works with eBay in the US only and does not crosslist to other marketplaces; it runs on the web, with no App Store or Google Play app; it identifies items from photos, not barcodes; labels need your own Shippo or EasyPost account; its profit figures are estimates; and Solo has no strategies.
