Quick answer
What is the best Chrome extension for Facebook Marketplace?
It depends on the job. For sellers, burstRepost is the pick: it copies eBay listings into Facebook Marketplace in bulk, is free to try and costs a one-off A$20 for life. For new-listing alerts, CarSnipe (cars only, from $9.99 a month, browser must stay open) and the free Facebook Marketplace Enhanced are the extensions to know; for valuing a listing, Spottable, Flipr and Underpriced. For alerts that keep running when your computer is off, Outpost Alerts is the better choice: it runs in the cloud, checks your fastest watchlist as often as every minute and needs no Facebook login.

Facebook Marketplace extensions at a glance
Every fact below comes from each extension’s Chrome Web Store page or its maker’s own site, checked on 13 October 2026. Ratings are Chrome Web Store ratings on that day; most are based on a handful of reviews, so treat them as a weak signal. We have not tested these extensions; this is based on their public pages.
| Extension | Job | Price | Sends new-listing alerts? | Store rating |
|---|---|---|---|---|
| burstRepost | Bulk cross-listing from eBay to Marketplace | Free to try, then A$20 one-off (lifetime) | No (a seller tool) | 5.0 from 3 ratings |
| CarSnipe | Alerts (vehicles only) | $9.99/mo (2 searches) or $24.99/mo (unlimited) | Yes, to Telegram, while your browser is open | Sold from its own site |
| Facebook Marketplace Enhanced | Saved searches, new-listing badge | Free | A count on the extension icon; no notifications mentioned | 3.4 from 5 ratings |
| Better Marketplace Pro | Search helper | In-app purchases, prices not stated | Not mentioned | 1.3 from 13 ratings |
| Spottable | Deal checker | In-app purchases, prices not stated | No (alerts are in its separate app) | 4.3 from 6 ratings |
| Flipr | Deal checker (eBay sold data) | Free core; Pro price not stated | No | 5.0 from 4 ratings |
| Underpriced | Deal checker | 5 free checks, then from $9.99/mo | No | Sold from its own site |
| Outpost Alerts (not an extension) | Alerts, every category | US$14.99/mo, 3-day trial | Yes: iPhone push, Discord, web dashboard, around the clock | App Store |
The rest of this guide goes through each job in turn, starting with the best value extension on the list, and then deals with the part none of the extensions can fix on their own: being early.
Best for sellers: burstRepost, eBay to Marketplace in bulk
If you already sell on eBay, the slowest part of adding Facebook Marketplace is retyping every listing: the title, the price, the condition, the description, the category, the pickup location, and re-uploading every photo. burstRepost does that work for you. It reads an eBay listing in one click and fills in Facebook Marketplace’s “Create new listing” form with the same details, so a listing that took ten minutes to copy by hand takes seconds.
The price is the headline. burstRepost is free to try, and the full version is a one-off A$20 for lifetime access. There is no monthly subscription, so it pays for itself the first time it saves you an evening of retyping, and it keeps costing nothing after that.
What burstRepost does
- One-click capture from any eBay listing. Saves the title, price, condition, description, category, location and photos from the eBay item page you are on.
- Bulk listing from many tabs at once. Open a batch of your eBay listings in separate tabs and burstRepost detects them all and builds a repost queue in one go.
- One draft or one per listing. Start a single Marketplace listing from the queue, or start one draft for every saved item and work through them.
- Auto-fill of every field, photos included. Title, price, condition, description, category, location and images go straight into the Marketplace form.
- Automatic category mapping. eBay’s categories are matched to the closest Facebook Marketplace category, so you are not hunting through menus for each item.
- Reseller presets. Save your usual pickup location, categories, condition, visibility and boost-after-publish settings once, and reuse them on every listing.
- Review before posting, or auto-publish. Check and edit every field before anything is filled in, or switch on the optional one-click auto-publish once you trust your presets.
- Private by design. It runs locally in your browser: saved listings and presets stay in your Chrome profile and no listing data is sent to an external server. It only reads the eBay and Facebook Marketplace pages you are on.
How it works
- Install burstRepost from the Chrome Web Store.
- Open the eBay listings you want to cross-list, one tab each, and capture them into the queue.
- Set your presets: pickup location, condition, visibility and whether to boost after publishing.
- Start the drafts. burstRepost fills each Marketplace form, you review it (or let auto-publish post it), and move to the next.
Who it suits
- eBay sellers adding Marketplace as a second channel for local pickup buyers.
- Resellers with a backlog of eBay stock that has never been listed anywhere else.
- Anyone tired of subscriptions: a one-off A$20 is the whole cost.
burstRepost is built in Sydney by the developer behind Outpost Alerts, so it is made by people who use Marketplace every day. It rates 5.0 from its first reviews on the Chrome Web Store. It works in Chrome and copies from eBay to Facebook Marketplace; it is meant for listings you own or are authorised to manage. If you are newer to selling on Marketplace, pair it with the guide to writing listings that sell.
Extensions that alert you to new listings
Only two of the extensions we could verify watch for new listings at all, and they work in quite different ways.
CarSnipe is a paid alert extension for vehicles. It runs in Chrome, Edge, Brave and Firefox, watches Facebook Marketplace for cars, SUVs, trucks and vans matching your filters, and sends each match to Telegram through its own bot, with the photo, price, mileage and drive time. Basic is $9.99 a month for two searches checked every 15 minutes; Pro is $24.99 a month for unlimited searches checked every 3 minutes, plus a market-value estimate and deal badges. There is a 7-day trial that needs a card. CarSnipe’s own site is clear that “monitoring runs while your browser is open”, and that your Facebook credentials are stored locally, encrypted, rather than on its servers. Our full CarSnipe review goes deeper on the plans.
Facebook Marketplace Enhanced is a free extension that lets you save searches with keywords, a location and a radius, marks listings you have not seen with a blue “NEW” badge, and shows a running count of new listings on the extension icon. Its store page does not mention desktop notifications, so in practice it tells you what is new when you look, rather than telling you the moment something appears. The listing does not name its developer.
| Tool | Cheapest plan | Fastest check | Marketplaces | Apps | Alerts by | Free plan / trial | Needs your Facebook login? |
|---|---|---|---|---|---|---|---|
| Outpost Alerts | US$14.99/mo | Every minute (Pro, fastest watchlist) | Facebook Marketplace | iPhone, web | Push, Discord, dashboard | 3-day trial | No |
| CarSnipe | $9.99/mo | 3 minutes (Pro) | Facebook Marketplace, vehicles only | Browser extension | Telegram | 7-day trial | Credentials stored locally |
| Facebook Marketplace Enhanced | Free | Not stated | Facebook Marketplace | Chrome extension | Icon badge count | Free | Not stated |
If you only want to know which alert tools exist across apps, websites and extensions together, the comparison of Facebook Marketplace alert apps covers the wider field.
Extensions that improve the search page
The next group does not alert you at all. It changes what you see while you are on Marketplace, which helps if your complaint is that the search page is hard to work with.
Better Marketplace Pro, from Spring Retro Games, is the most complete of these. Its store page lists estimated listing dates on the grid view, saved searches that surface the most recent listings, dimming of listings you have already looked at, your own spam filters to hide unwanted results, sorting by newest in categories that lack it, and a search radius of up to 500 miles. It offers in-app purchases, but the page gives no prices. Its rating was 1.3 from 13 reviews on the day we checked, which is worth reading before you pay for anything.
Most of what these helpers add can be done, more slowly, with Facebook’s own filters. The guide to sorting Marketplace by newest shows the built-in route on the app and desktop, and the search tips guide covers the wording that turns up listings other buyers miss. Hiding junk results is the other common request; Facebook has no exclude box, which is why excluding words from Marketplace results takes a separate tool.
Extensions that value a listing for you
The last group answers the question “is this a good price?” once you are already looking at a listing. None of the three below sends new-listing alerts.
- Spottable, from Harbourside Apps in Neutral Bay, New South Wales, gives each listing a deal score out of 10, a verdict (Great Deal, Fair Price, Overpriced or Avoid), a suggested fair price, a condition read and red-flag warnings. It can analyse up to 20 search results at once and draft a negotiation message. It has in-app purchases with no prices on the store page. Spottable’s saved searches and alerts live in its separate iPhone app, not in the extension.
- Flipr, from a Seattle developer, puts eBay sold and active listing data on Facebook Marketplace listings, works out eBay fees for your seller tier, and gives a maximum offer that still meets your profit target. The core features are free without an account; a Pro tier adds bulk analysis of up to 50 listings and a deal pipeline, but its price is not on the page.
- Underpriced runs in Chrome and Firefox and shows a listing’s estimated value, profit after fees and a buy-or-pass call. The first five checks are free with no card; plans start at $9.99 a month, with the first month at $4.99.
These are useful once you have a listing in front of you, and the guide to Marketplace deal finders compares this kind of scoring with alerting in more depth. The catch is the order of events: a deal checker can only value the listings you have already found, and the best-priced listings are the ones least likely to still be there when you find them.
Why an extension will not get you to the good listings first
Here is the problem every Marketplace buyer runs into eventually. A well-priced listing — a bike, a console, a dining set from someone moving interstate — collects its first messages within minutes, and is often marked pending within the hour. The person who gets it is the one who messaged first, not the one who was keenest. Refreshing the app more often narrows the gaps between your checks, but it never closes them, and the good listings live and die inside those gaps.
Browser extensions run inside your browser, so they inherit its schedule. When the laptop lid is closed, the computer sleeps or Chrome is shut, an extension cannot check anything. CarSnipe says so directly. That leaves the hours you most need covering — the commute, the workday, the evening away from the desk — uncovered by exactly the tools meant to watch for you.
The second issue is your Facebook account. Some extensions work through your own logged-in session or store your Facebook credentials locally. That is not unsafe in itself, but it does tie the tool’s activity to your personal account, and some tools say nothing about it either way.
A cloud service avoids both problems. It searches Marketplace from its own servers, around the clock, and sends the match to your phone, so it does not matter whether your computer is on, and your Facebook account is not involved. The free alert options are worth knowing about for the same reason: most of them check hourly, and an hourly alert usually tells you what has already sold.
Before you install any Marketplace extension
Marketplace extensions read the pages you visit, and some read a great deal more. A few checks take a minute and save regret.
- Read the permissions. The Chrome Web Store lists what an extension can access. A deal checker that only needs Marketplace pages should not need every site you visit.
- Look at who makes it. Some listings name a company and address; some name nobody. That is not proof of anything, but it tells you who you could contact.
- Treat small ratings carefully. Most extensions in this guide have between 4 and 13 ratings. A 5.0 from four people and a 1.3 from thirteen are both thin evidence.
- Check whether it wants your Facebook password. If it does, understand where that password is stored before you hand it over.
- Find the price before you depend on it. Several store pages say “offers in-app purchases” with no amounts. Know what you will pay once a free tier runs out.
Where Outpost Alerts fits
Outpost Alerts is not a browser extension. It is an Australian-built service that watches Facebook Marketplace for new listings matching your keywords and sends them to an iPhone app, a web dashboard or Discord. It does the one job in this guide that extensions are worst placed to do: watching for new listings while you are doing something else.
- It runs in the cloud. Your computer can be off and your phone in your pocket. There is no extension to keep running.
- No Facebook login. Outpost searches Marketplace from its own servers, so your account is never involved.
- Fast where it matters. Your fastest watchlist is checked every minute on Pro, every 3 minutes on Standard and every 30 minutes on Basic; the other watchlists run more slowly (3 minutes or more on Pro, 5 minutes or more on Standard).
- Relevance filtering. Across 30,777 listings that matched a keyword, 38.6% were discarded as not the item being searched for (18,890 kept, 11,887 rejected), so cases, “wanted” posts and box-only listings stay out of your alerts.
- Every category. Consoles, furniture, tools, bikes and cars, each with include and exclude words, a price range and one location with a 5-500 km radius per watchlist.
What it does not do: it does not score deals or estimate resale value, so a deal checker such as Spottable or Flipr can still sit alongside it. It covers Facebook Marketplace only, there is no Android app (Android users use the web dashboard), and there is no free plan. Plans start at US$14.99 a month with a 3-day trial. If you prefer alerts on your phone, the iPhone alert app comparison puts Outpost beside the other apps, and the Discord guide shows how alerts land in a channel.
FAQ
What is the best Chrome extension for Facebook Marketplace?
It depends on the job. For sellers, burstRepost is the pick: it copies eBay listings into Facebook Marketplace in bulk, is free to try and costs a one-off A$20 for life. For new-listing alerts, CarSnipe (cars only, from $9.99 a month, browser must stay open) and the free Facebook Marketplace Enhanced are the extensions to know; for valuing a listing, Spottable, Flipr and Underpriced. For alerts that keep running when your computer is off, Outpost Alerts is the better choice: it runs in the cloud and needs no Facebook login.
Is there an extension to cross-list from eBay to Facebook Marketplace?
Yes. burstRepost captures an eBay listing in one click, including photos, and fills in the Facebook Marketplace listing form for you. It can queue many eBay tabs at once for bulk listing, maps eBay categories to Marketplace ones, and saves presets for location and boosting. It is free to try and costs a one-off A$20 for lifetime access.
Is there a Chrome extension that alerts me to new Facebook Marketplace listings?
Yes. CarSnipe sends vehicle listings to Telegram while your browser is open, and Facebook Marketplace Enhanced shows a count of new listings on its icon. Both depend on your browser running. A cloud service such as Outpost Alerts keeps checking when your computer is off and sends matches to an iPhone app, a web dashboard or Discord.
Do Facebook Marketplace extensions work when my computer is off?
No. A browser extension runs inside your browser, so it stops when the computer sleeps or the browser closes. CarSnipe states that its monitoring runs only while your browser is open. To get alerts around the clock you need a service that runs on its own servers.
Is there a Facebook Marketplace extension for Firefox?
Some. CarSnipe supports Firefox as well as Chrome, Edge and Brave, and Underpriced has a Firefox version. Most of the other Marketplace extensions in this guide are listed for Chrome only.
Can an extension sort Facebook Marketplace by newest?
Better Marketplace Pro adds sorting by newest to categories that lack it, along with estimated listing dates. Facebook itself also lets you sort many searches by date listed. Neither tells you when a new listing appears; for that you need an alert.
Are Facebook Marketplace Chrome extensions safe?
Many are fine, but check before installing: read the permissions on the Chrome Web Store page, see who makes it, be wary of ratings based on a handful of reviews, and find out whether it asks for your Facebook password and where it stores it.
