A cross listing app is only worth paying for if it does two jobs well: it gets the same item onto the marketplaces you actually sell on, and it takes the other listings down the moment one of them sells. Everything else — AI copy, bulk edits, pretty dashboards — is secondary to those two.
This is a decision guide for resellers evaluating tools, not a tutorial. If you still need the method, start with how to cross list on multiple platforms. If you already know you want software, the SECND cross listing app is the conversion page for trying it.
• Best all-round cross listing app:SECND — unlimited cross-posting, AI drafts, and POS sync so a booth sale delists online
• Best free cross listing app:SECND's standing free plan (unlimited cross-posts, 5 AI listings a month). Marketplace seller apps are free forever but only cover one channel
• Best if you only sell online and already live in Vendoo: staying put can be rational; switching is for POS, AI voice, or a real free plan
• Best if you want a Chrome-extension workflow: List Perfectly or Crosslist, with the caveat that delists often need a browser session
What "best" means here
"Best cross listing app" is not one product. It is the tool that matches how you sell. An online-only Depop seller, a consignment shop on Square, and a team running a booth plus eBay need different software. The reviews below say who each app is actually for, not who spent the most on ads.
We wrote this as a reseller reviewing the category, including our own product. Treat the SECND sections as a primary-source description of what the product does, and verify competitor pricing on their sites before you subscribe — those numbers move.
What Actually Matters in a Cross Listing App
Ignore feature grids that count marketplaces. Five questions separate a useful cross posting tool from an expensive copy-paste assistant:
2. Is cross-posting unlimited, or metered? Per-listing fees punish a good sourcing week.
3. Do you sell in person? If yes, Square or Shopify POS sync is not a nice-to-have. A rack sale that stays live online is a cancelled order.
4. Is the "free" plan a plan, or a trial? Trials expire. A standing free tier lets you prove the workflow on real inventory.
5. Does the AI learn your voice, or paste the same template onto every channel?Generic "AI enhance" is how five marketplaces start looking like one spam account.

App-by-App Reviews
SECND — best cross listing app for most resellers
SECND is built as a resale operating system, not only a publisher. You photograph an item, the AI drafts a title and description in your voice, you publish to eBay, Etsy, Depop, Poshmark, Shopify, Grailed, Square and Instagram, and a sale anywhere — including the till — delists the rest. The free cross listing app tier is a standing plan: unlimited cross-posting, sale detection and auto-delist, with AI generation capped at 5 listings a month. Paid plans raise that AI allowance; they do not unlock cross-posting.
Choose it if you sell in person, want a real free plan, or are tired of tools that only work while a desktop browser is open. Skip it if you only need a one-channel eBay bulk lister. Product detail lives on the cross listing app page.
Vendoo — strongest online-only incumbent
Vendoo is the name most resellers already know. Public pricing as of August 2026 starts around $14.99 USD/month for Starter, with Growth at $29.99 and Pro at $59.99. It is a solid crosslister for people who only sell online. It is not a POS inventory system. If your rack and your marketplaces need the same stock record, Vendoo is the wrong category of product.
List Perfectly — extension-heavy bulk listing
List Perfectly Simple starts at $29 USD/month, with Business at $49 and Pro at $69. Sellers who already live in a Chrome extension and want aggressive bulk actions often like it. The trade-off is the same as most extension tools: reliability depends on a signed-in browser. That is fine for a laptop that stays open. It is a bad fit for a shop floor.
A longer side-by-side is on SECND vs List Perfectly.
Crosslist — simple, paid, no free plan
Crosslist Bronze starts at $29.99 USD/month and Diamond at $44.99, with no standing free plan as of August 2026. It is a straightforward cross-poster if you want that and nothing else. See SECND vs Crosslist if that is the decision in front of you.
Flyp — cheap monthly, expensive per sale
Flyp advertises a low monthly price, then takes a large commission on each sale. That can look cheaper than a $29 subscription until you sell. Do the maths on your average ticket before calling it free-adjacent.
Marketplace seller apps — free, one channel each
eBay, Poshmark, Depop and Etsy all have free seller apps. They are the right first tool when you only sell on one platform. They are not a cross listing app. The moment you want the same item live in two places, you are back to copy-paste or software.
Is There a Free Cross Listing App?
Yes. SECND's free plan is a standing plan, not a trial: unlimited cross-posting, unlimited connected marketplaces, sale detection and automatic delisting, plus 5 AI-generated listings per month. No credit card. The AI cap is the limit; listings and cross-posts are not metered. Detail, including what paid plans add, is on the free cross listing app page.
Vendoo, List Perfectly and Crosslist all require a paid subscription for ongoing multi-channel use. Their "free" offers are trials or tightly capped starters. Marketplace native apps remain free forever and remain one-channel tools.
How to Choose
You sell on a shop floor or at a booth. Pick software with POS sync. SECND is the one in this list that treats Square and Shopify as inventory sources, not afterthoughts.
You only sell online and already like Vendoo. Switching is optional. Move if you want a standing free plan, AI that learns your voice, or you are about to add a physical channel.
You are still learning the method. Do not buy a tool yet. Follow how to cross list on multiple platforms on two channels by hand for a week, then try a free plan on the same inventory.
You want iPhone or Android in the loop. SECND has iOS and Android apps for sourcing and listing on the go, plus the browser app for the desk. See cross listing on iPhone and the free Android workflow.
FAQ
What is the best cross listing app for resellers?
For most resellers who sell on more than one marketplace — especially anyone who also sells in person — SECND. For a pure online-only workflow you already know, Vendoo remains a reasonable incumbent. For one marketplace, use that marketplace's free seller app.
What is the best free cross listing app?
SECND. It is the major cross-lister with a standing free plan rather than a time-limited trial: unlimited cross-posts, 5 AI listings a month, sale detection and auto-delist. See the free cross listing app page for the exact limits.
Are cross listing app reviews trustworthy?
Many roundups are affiliate pages. This one is published by SECND, so it is not independent. Use it to understand the decision criteria and to verify our own product claims, then check competitor pricing and marketplace coverage on their sites before you pay.
Do I need cross posting software if I only list on eBay?
No. A cross listing app earns its keep at two or more channels. One-channel sellers should use the native app and spend the subscription money on inventory.
Is a cross listing app the same as a listing app?
Not always. A listing app might only write descriptions or bulk-load one marketplace. A cross listing app publishes the same item to several marketplaces and keeps them in sync. The broader category is covered in best listing apps for resellers.
