Why we built this
Good deals sell in minutes. By the time you've refreshed five different apps, someone else has already messaged the seller. We built List Mantis because we got tired of being the third reply.
The refresh game
Five apps open, thumb bouncing between them. It's a full-time job.
Gone in sixty seconds
The best listings get snapped up in minutes. If you aren't there, you aren't getting it.
Five apps, five logins
Each marketplace has its own quirks, filters, and gotchas. It's exhausting keeping up with them all.
How it works
Three steps. That's it.
Set it up once, then let the mantis keep watch.
We watch, 24/7
Our worker polls every few minutes across all five marketplaces. Synonyms, stopwords, and location filters run automatically.

Instant push to your phone plus a clean email digest. Tap to jump straight to the listing — before anyone else does.

Features
Built for people who are serious about a good deal.
All five marketplaces
Facebook Marketplace, eBay (coming soon), Gumtree, AutoTrader and Vinted — covered in one feed.
Instant alerts
Push notifications on iOS and the web, plus clean email digests. Delivered the moment we spot a match.
Smart matching
Synonyms, stopwords and fuzzy matching catch listings that simple keyword search would miss.
Location-aware
Set a UK postcode and a radius. You only see listings you can actually drive to.
Vehicle intelligence

Zero noise
Warm-up windows, dedupe rules, and tight filters keep your inbox clean. Only real matches get through.
Vehicle searches
Buying a car? We check the MOT for you.
List Mantis spots a vehicle listing, extracts the registration plate straight from the photos, and pulls its MOT history from the DVSA — the government's official database. No opening new tabs. No copy-pasting plates. Just the facts, right there in your alert.
- Full MOT history, including advisories and failures
- Recorded mileage over time — spot clockers at a glance
- Fuel type, road tax status, and more
Data straight from the DVSA — gov.uk's official MOT database

FAQ
Answers to the usual questions.
Didn't find what you need? Email hello@listmantis.com and we'll get back to you.
Is this legal?
We only access publicly available listing data — the same data you'd see by browsing the marketplace yourself. We don't scrape private accounts, bypass logins, or resell listing data. We are not affiliated with Facebook, Meta, eBay, Gumtree, AutoTrader or Vinted.
Which marketplaces are covered?
Facebook Marketplace, eBay (coming soon), Gumtree, AutoTrader, and Vinted. We're UK-focused — listings outside the UK are filtered out by default.
How fast are the alerts?
Our worker polls every few minutes on every plan. We can't promise sub-second delivery — marketplaces rate-limit us too — but you'll typically get a ping within a minute or two of a listing going live.
Is there an iOS app?
An iOS app is in development for native push notifications. Web push also works on most modern browsers in the meantime.
How much will it cost?
Two plans: Standard at £9.99 / month (up to 5 saved searches) and Pro at £24.99 / month (up to 20). Both plans include every feature — push notifications, real-time polling, vehicle intelligence, all five marketplaces. The only difference is the search count. Both come with a 7-day free trial — cancel any time before it ends and pay nothing. Existing beta testers get Pro features free through the launch period.
How do I get access?
New signups are closed while we prepare for public launch on the App Store. Follow this page for launch news — when we go live, sign-up opens to everyone. Existing beta testers can still sign in here.
What happens to my data?
We only collect what's needed to run your searches and send you alerts. No advertising cookies, no data brokers, no reselling. See the full privacy policy for details.
