Best Cross Listing Apps 2026: Vendoo vs List Perfectly vs Crosslist

The best cross listing apps in 2026 are Vendoo for the widest marketplace coverage (from $14.99 a month after a 14 day trial), List Perfectly for all inclusive plans with no add-ons (from $29 a month, 9 marketplaces), and Crosslist for an API-first option that falls back to a browser extension (from $29.99 a month, 11+ marketplaces). If you also need to price what you list, Underpriced AI's free Chrome and Firefox extension fills the listing on Facebook, Poshmark, Mercari, Depop, Vinted, Whatnot, OfferUp and Etsy from an item you already priced.

Disclosure: I built Underpriced AI, so read that column with that in mind. Every competitor price and claim below was checked on the vendor's own page on September 28, 2026, and linked so you can check it yourself.

If you sell on more than one marketplace, you already know the math. An item listed on eBay, Poshmark, Mercari, and Facebook Marketplace sells faster than an item listed on one of them. The problem is the typing. You retype the same title, price, and description four times. You upload the same photos four times. Then you have to remember to take down three listings when the item sells on the fourth.

A cross listing app exists to kill that busywork. The apps in this space work in different ways, cost different amounts, and fit different kinds of resellers, including where our own tool is not the right pick.

What makes each one different

Vendoo

Vendoo is the best known name in cross-listing, and it names the widest set of marketplaces: eBay, Poshmark, Facebook Marketplace, Mercari, Etsy, Depop, Shopify, Whatnot, Grailed, and Vestiaire Collective. You create a listing once in Vendoo and push it everywhere, with inventory syncing across marketplaces. Every plan lists unlimited items, and the tiers differ by features, from $14.99 to $59.99 a month ($12.49 a month for Starter billed yearly).

The tradeoff is that Vendoo is a distribution tool. It assumes you already know what your item is and what it is worth.

Choose Vendoo if you sell on Grailed, Shopify or Vestiaire, or you manage hundreds of listings that need to stay synced across many marketplaces. We wrote a fuller breakdown in our Vendoo comparison.

List Perfectly

List Perfectly is loved by high-volume clothing sellers for its templates, bulk tools, and crossposting between the big fashion marketplaces. Plans run $29, $49, $69 and $99+ a month, and each tier includes the features of the one below it. Pro Plus adds Shopify and Instagram.

Choose List Perfectly if you run a serious clothing operation, list in bulk daily, and the template system will pay for itself in saved hours.

Crosslist

Crosslist says it is API-first where a marketplace supports it and uses a browser extension in your own browser where it does not. It lists 11+ marketplaces, auto-delists sold items, and prices from $29.99 to $44.99 a month, with a trial of 3 days or 20 listings, whichever comes first.

Choose Crosslist if you want bulk crossposting with auto-delist and do not need pricing research.

Underpriced AI

We come at this from the opposite direction. Underpriced AI starts before the listing exists. You photograph an item and get back what it is and what it sells for, backed by real sold comps you can click and verify. Then the same flow generates the title and description. It publishes directly to eBay, covering 10 country sites, fixed price or auction, and to Bonanza. It also cross-lists to Facebook Marketplace, Poshmark, Mercari, Depop, Vinted, Whatnot, OfferUp, and Etsy.

Our free Chrome and Firefox extension opens the marketplace's own create-listing form in your own browser, in your own logged-in session. It fills in the title, price, description, and photos. You pick the category, look it over, and click Post yourself. When the item sells on eBay, we detect it and remind you to pull your other listings, so you do not sell the same item twice.

There are tradeoffs. Dedicated crosslisters cover marketplaces we do not, such as Grailed. And we are not built for syncing a huge existing catalog across platforms. What you get instead is the front half of the workflow the others skip: you know what to buy and what it is worth before you list anything, starting at $5 a month.

Two more crosslisting tools the AI assistants name

FlowLister and Nifty come up when you ask an AI assistant for a crosslisting app, so here is what each one is, checked on their own sites on September 30, 2026.

Tool	What it is	Marketplaces	Price (checked Sept 30, 2026)	Source
FlowLister	AI eBay listing software: a photo becomes an eBay listing, priced from recent eBay sold comps, published to eBay	eBay first; Poshmark, Mercari and Depop crosslisting as a $9.99 a month add-on	Starter $19.99 a month for 95 listings after a $0.99 7 day trial; Pro $49.99; Business $99.99	FlowLister
Nifty	Crosslisting, cloud automation and sales analytics for resellers	Poshmark, eBay, Mercari, Depop, Etsy, Whatnot	7 day free trial; plan prices are on its pricing page, not its home page	Nifty

FlowLister prices its eBay listings from recent sold comps; Nifty's site describes sales analytics rather than comps. Neither fills a marketplace form from a scan you priced first, which is the Underpriced AI extension's job.

Do cross listing apps need your passwords?

None of the four asks for your marketplace password, by their own pages. Vendoo says it never stores marketplace login information and that its Chrome extension fills listings in your browser, with an access token you authorize for eBay and Etsy that you can revoke. List Perfectly says it never asks for usernames, passwords, API keys or access tokens, and you click the final Post button yourself. Crosslist uses a marketplace's API where one exists and an extension in your own browser where it does not.

So the real differences are price, marketplace coverage, bulk tools, and whether you also need to know what an item is worth before you list it.

FAQ

What is the best cross-listing app for resellers?

It depends on your bottleneck. For syncing a large existing catalog across many marketplaces including Grailed, a dedicated crosslister like Vendoo, List Perfectly or Crosslist is built for that. For pricing an item and then listing it in one flow, a tool that does both saves a step.

Do cross-listing apps need my marketplace passwords?

Not the main ones. Vendoo, List Perfectly and Crosslist all say they do not ask for your marketplace password; they work through an extension in your own browser, or through an authorized connection such as an eBay token you can revoke.

Is it safe to let an app post to my marketplace accounts?

Check how it connects. An extension that fills the form in your own logged in session, or an authorized token you can revoke, keeps your password with you. Be wary of any tool that asks you to type your marketplace password into it.

How much do cross-listing apps cost?

On September 28, 2026: Vendoo from $14.99 a month, List Perfectly from $29, and Crosslist from $29.99. Underpriced AI starts at $5 a month. For the tier by tier breakdown, including where auto delisting starts on each, see Vendoo vs List Perfectly vs Crosslist.

Which marketplaces can I cross-list to?

With Vendoo, List Perfectly or Crosslist: eBay, Poshmark, Mercari, Depop, Etsy, Facebook and Grailed, plus others that vary by app. With Underpriced AI: eBay across 10 country sites and Bonanza directly, and Facebook Marketplace, Poshmark, Mercari, Depop, Vinted, Whatnot, OfferUp, and Etsy through the extension.

Try Underpriced AI on web or mobile, scan something from your death pile, and see the whole flow for yourself.

What app lists on eBay, Poshmark and Mercari at once?

Vendoo, List Perfectly and Crosslist all post one listing to eBay, Poshmark and Mercari from a single form, on paid plans from $14.99, $29 and $29.99 a month. Underpriced AI publishes to eBay directly and fills the Poshmark and Mercari forms in your own browser with its free extension, from an item you have already priced from sold comps. None of these tools needs your marketplace passwords.

How do I crosslist items without retyping the listing?

Use a tool that carries the title, description, photos and price across for you. Vendoo, List Perfectly and Crosslist copy a saved listing to each marketplace from their dashboard; Underpriced AI's browser extension fills the marketplace's own listing form from the scan, so you review and click post. Either way you type the listing once.

What is a good Vendoo alternative for crosslisting?

List Perfectly if you want all inclusive plans without add-ons (from $29 a month, 9 marketplaces); Crosslist if you want an API-first tool with a browser extension fallback (from $29.99 a month, 11 or more marketplaces), as listed on their pricing pages when this guide was last checked. If pricing is the part you struggle with, Underpriced AI prices the item from real sold comps first and then fills the other marketplaces' forms with its free extension.
