Selling on just one marketplace is like fishing in a small pond. You might catch something, but the big fish are swimming elsewhere.
UK resellers today sell across eBay, Depop, Etsy, and other marketplaces. But listing the same items on five marketplaces manually takes hours you don’t have.
That’s where crosslisting apps come in. These apps let you create a listing once and post it on multiple marketplaces in minutes.
The problem? Most crosslisting apps are built for sellers in the US. Many don’t even work in the UK, and choosing the wrong one will waste both your time and money.
In this guide, we’ll rank the 6 best crosslisting apps for UK sellers. We compare their features, pricing, reviews, and pros and cons so you can pick the right one with confidence.
Why Do UK Sellers Need a Crosslisting App?
The UK secondhand market is worth over £7 billion and growing every year. Buyers are spread across eBay, Depop, Vinted, Etsy, and more.
Listing the same item manually on each marketplace takes 5–10 minutes per marketplace. Multiply that by 100 items across 4 marketplaces, and you’re losing entire weekends to copy-pasting.
A good crosslisting app solves three big problems for UK sellers at once:
1. Time: List once and publish everywhere in a couple of clicks.
2. Double-selling: Auto-delist removes sold items from other marketplaces instantly.
3. Reach: More marketplaces mean more eyes on your items and faster sales.

1. Sidekick Tools
Sidekick Tools tops our best crosslisting app for UK list, and for good reason. It’s the only app here that has crosslisting, marketplace automation, and AI listing tools in one affordable package.
While other crosslisting tools stop at copying your listings, Sidekick Tools actively grows your sales. It relists stale items, sends offers to interested buyers, and keeps your listings visible around the clock.
Sidekick Tools Features
Sidekick Tools lets you crosslist to 7 major marketplaces, including eBay, Depop, Etsy, Grailed, Mercari, Whatnot, and Poshmark. UK sellers can list an item across their key platforms in about 30 seconds.
The app’s auto-delist feature detects a sale on one marketplace and removes the item everywhere else. That means no more double-selling and no more awkward cancellation messages.
Beyond crosslisting, you get a full automation suite. Sidekick Tools handles relisting, automatic auctions, and sending offers to likers on eBay, Depop, and Mercari — all on autopilot.
Its AI toolkit is another standout. The AI Stock Photo Creator turns basic photos into professional product shots, while the bulk background remover and description generator polish your listings in seconds.
You also get bulk editing tools (via the SmartFill feature) to update prices, titles, and tags across hundreds of listings at once. Plus, built-in sales reports and analytics show you exactly what’s selling and where.
Unlike most rivals, Sidekick Tools works everywhere. It offers fully featured apps for iOS, Android, and the web, so you can list items from the sofa or straight from a car boot sale.
Sidekick Tools Pricing
Sidekick Tools offers some of the most flexible pricing in the industry. Crosslisting-only plans start at just $9.99 per month, making it the cheapest entry point on this list.
Plans scale with your inventory, from 100 crosslisted items up to enterprise levels. Full-access subscriptions with complete automation start at $29.99 per month.
Best of all, every new user gets a free 7-day trial with no credit card required. You can test everything risk-free before spending a penny.
Pros
1. Cheapest starting price of any major crosslisting app ($9.99/mo)
2. Crosslisting, automation, and AI tools in one app
3. Auto-delist included on core plans — no expensive upgrades needed
4. Free 7-day trial with no credit card required
5. Mobile apps for iOS and Android, plus a web app
6. Bulk editing, relisting, and offers to likers save hours weekly
Cons
1. Supports only 7 marketplaces
2. No Vinted integration yet
Verdict:
For UK sellers who want maximum sales with minimum effort, Sidekick Tools is the best crosslisting app available. It does more than any competitor at a lower price.
2. Vendoo
Vendoo is one of the biggest names in crosslisting, trusted by over 81,000 resellers. It recently simplified its pricing, which makes it more appealing than before.
Its main draw is breadth. Vendoo connects to 10 marketplaces, including eBay, Depop, Etsy, Grailed, and Shopify.
Vendoo Features
Vendoo lets you create a listing once and push it to all supported platforms from a single dashboard. Its sale detection and auto-delist features remove sold items automatically to prevent double-selling.
The platform includes inventory management, profit tracking, and analytics that break down sales by marketplace, category, and brand. A native mobile app for iOS and Android lets you manage listings on the go.
Right now, Vendoo doesn’t support Vinted, which is bad news for UK sellers.
Vendoo Pricing
Vendoo offers three plans: Starter ($14.99/month), Growth ($29.99/month), and Pro ($59.99/month), all with unlimited listings. Note that these headline prices reflect monthly billing — annual billing costs less.
Keep in mind that key features like AI tools and bulk actions only unlock on the Growth plan and above. UK sellers should also check the region-specific pricing page, which can differ from US pricing.
The 14-day free trial requires a credit card and bills automatically if you forget to cancel.
Pros:
1. Supports 10 marketplaces
2. Sale detection and auto-delist included
3. Solid mobile app and analytics
4. Unlimited listing
Cons:
1. Costs more than Sidekick Tools at every comparable tier
2. AI and bulk tools locked behind the $29.99 Growth plan
3. Trial requires a credit card upfront
4. Batch crosslisting processes items one by one
Verdict:
Vendoo is a strong all-rounder for sellers who need lots of marketplaces. But you’ll pay noticeably more for features Sidekick Tools includes at lower tiers.
3. Crosslist
Crosslist is a popular browser-based crosslisting tool known for its clean, single-form listing workflow. Fill out one form, and your listing goes to every selected marketplace.
It supports UK variants of major marketplaces, including eBay UK and Vinted, which makes it genuinely useful for UK resellers.
Crosslist Features
Crosslist supports 10+ marketplaces and handles UK, US, CA, and AU marketplace variants. You can set automatic price markups or markdowns per marketplace, which helps offset different fee structures.
Its bulk tools are impressive. You can bulk delist, relist, edit, delete, and change prices across your whole inventory.
Sales detection and auto-delist are available, but only on the pricier Gold plan ($39.99/mo). AI tools like description generation and background removal cost an extra $4.99 per month.
The big catch? Crosslist runs through a Chrome browser extension on desktop. There’s no mobile app, so you can’t list on the move.
Crosslist Pricing
Crosslist offers four tiers: Bronze ($29.99/month), Silver, Gold ($39.99/month), and Diamond ($44.99/month), based on how many new listings you create monthly.
There’s no free trial. You pay first and rely on a short money-back guarantee if it’s not for you.
Pros:
1. Clean “one form, all platforms” workflow
2. Supports UK marketplace variants, including Vinted
3. Powerful bulk actions and per-marketplace pricing rules
4. Detailed analytics dashboard
Cons:
1. Expensive — starts at $29.99/mo (3x Sidekick Tools’ entry price)
2. No free trial and no mobile app
3. Auto-delist locked behind the $39.99 Gold plan
4. AI features cost an extra $4.99/mo
Verdict:
Crosslist is a capable desktop crosslisting tool for high-volume listers. But its high price and missing mobile app hold it back for everyday UK sellers.
4. SellerAider
SellerAider stands out with the broadest marketplace coverage on this list. It connects to 15+ platforms, including UK and EU favorites like Vinted, Shpock, and Vestiaire Collective.
For sellers on niche platforms that no other crosslisting tool touches, SellerAider fills a real gap.
SellerAider Features
SellerAider works through a browser extension that copies listing data from one marketplace to another. Take a photo, and its AI can generate a full listing with title, description, and suggested price.
It also bundles free automation tools for Vinted, Depop, and Poshmark, covering tasks like refreshing listings and sending offers. That’s a nice bonus for UK Vinted sellers.
However, there’s a significant limitation. SellerAider copies your data over but doesn’t automatically post listings. You must review and publish each one manually.
Also, automatic delisting is only available on the Pro plan.
SellerAider Pricing
SellerAider keeps pricing simple: Crosslister Standard at $12.99/month and Crosslister Pro at $29.99/month (which adds auto-delist and automation). There are no per-listing caps.
A 14-day free trial is available with no credit card required.
Pros:
1. Widest marketplace support (15+), including Vinted and Shpock
2. Low starting price at $12.99/mo with no listing caps
3. Free Vinted, Depop, and Poshmark automation included
4. AI listing generation from a photo
Cons:
1. Doesn’t auto-post listings — manual review required for each one
2. Auto-delist only on the $29.99 Pro plan
3. Browser-extension based with no mobile app
4. Mixed independent reviews on reliability
Verdict:
SellerAider suits UK sellers who need niche platforms like Shpock or Vestiaire Collective. For serious, hands-off crosslisting, though, it can’t match Sidekick Tools.
5. Zipsale
Zipsale is a crosslisting tool designed specifically for UK resellers. It prices in pounds and focuses on the platforms UK resellers actually use.
If Vinted is the heart of your business, Zipsale deserves a look.
Zipsale Features
Zipsale supports 8 marketplaces, including eBay, Depop, Vinted, Etsy, Shopify, and Facebook Marketplace. Notably, it skips US-only platforms like Poshmark that UK sellers can’t use anyway.
Its import tool pulls in your existing inventory with a few clicks. Auto-listing works for some marketplaces, though moving items to eBay often requires manually filling in extra fields.
Auto-delist covers every platform except Facebook Marketplace. Handy extras include a “sell similar” feature, bulk actions, and paid add-ons for Depop relisting and Vinted offers.
One caveat: Zipsale is designed for single-quantity items. If you sell multi-quantity retail stock, it won’t fit your workflow.
Zipsale Pricing
Zipsale offers a free plan (10 items/month), then paid tiers: Part Time (£15/month + VAT, 100 items), Basic (£25/month, 200 items), Start (£45/month, 500 items), Growth (£79/month, 1,500 items), Pro (£99/month, 3,000 items), and Business (£149+).
The VAT on top makes it pricier than the sticker price suggests. The Part Time plan effectively costs £18 per month.
Pros:
1. Built for the UK market with GBP pricing
2. Supports Vinted, plus Depop and Vinted automation add-ons
3. Free plan available to test the waters
4. Auto-delist on nearly all platforms
Cons:
1. Poor Trustpilot rating (2.6/5) with reliability complaints
2. VAT pushes real costs above advertised prices
3. Single-quantity items only
4. No mobile app and no AI listing tools
Verdict:
Zipsale looks great on paper for UK sellers, but its weak reviews suggest caution. Test the free plan thoroughly before paying.
6. Voolist
Voolist is a cloud-based crosslisting platform with a clean interface and fair pricing. It runs entirely in your browser — no extensions, no desktop dependency.
Its unique angle? Deep support for self-hosted stores like Shopify, WooCommerce, and BigCommerce alongside major marketplaces.
Voolist Features
Voolist supports 7 platforms: eBay, Poshmark, Depop, Etsy, Shopify, WooCommerce, and BigCommerce. UK, EU, and Australian sellers are officially supported.
Because it’s cloud-based, its inventory sync and auto-delist run 24/7, even with your computer off. When an item sells anywhere, Voolist removes it everywhere else in near real-time.
True bulk crosslisting is another strength. Select 50 items, click once, and they publish simultaneously rather than queuing one by one.
Every plan also includes an AI writing assistant that generates titles and descriptions from your photos at no extra cost.
The downsides? No Vinted support yet (it’s in development), and no marketplace automation like offers or sharing.
Voolist Pricing
Voolist plans start at $19.99 per month, with tiers based on your number of active listings. Every plan includes all 7 marketplaces, auto-delist, and AI descriptions.
A money-back guarantee covers new signups, so you can try it with low risk.
Pros:
1. Cloud-based sync and auto-delist on every plan
2. True bulk crosslisting (simultaneous publishing)
3. Free AI descriptions included on all plans
4. Supports Shopify, WooCommerce, and BigCommerce stores
Cons:
1. No Vinted support yet — a gap for UK sellers
2. No marketplace automation (offers, sharing, relisting)
3. No native mobile app
4. Newer tool with a smaller track record
Verdict:
Voolist is an excellent pick if you run your own web store alongside marketplaces. For pure UK marketplace selling, however, it’s missing key platforms and automation.
Frequently Asked Questions (FAQs)
What is the best crosslisting app for UK sellers?
Sidekick Tools is the best crosslisting app for UK sellers in 2026. It combines crosslisting to 7 marketplaces, auto-delisting, bulk editing, AI listing tools, and marketplace automation, starting at just $9.99 per month with a free 7-day trial.
Do crosslisting apps work with UK marketplaces?
Yes, but coverage varies. Most crosslisting apps support eBay UK, Depop, and Etsy. Vinted support is rarer.
Can crosslisting apps prevent double-selling?
Yes. Apps with auto-delist (like Sidekick Tools) detect when an item sells on one platform and automatically remove it from all others, so you never sell the same item twice.
Are crosslisting apps worth the cost?
For anyone listing more than a handful of items monthly, absolutely. Crosslisting apps save roughly 40 hours per 1,000 listings and can multiply your sales by putting inventory in front of buyers on every platform.
Is crosslisting allowed on UK marketplaces?
Yes. Listing the same item on multiple marketplaces is allowed. Just make sure you remove sold items promptly — which is exactly what auto-delist features handle for you.
