Chrome notifications
Desktop notification the moment an audit detects a price change or a removed vehicle.
Avarus reads your inventory, downloads every photo, and auto-fills the entire Facebook Marketplace form — specs, photos, AI description. One click per car.
I've used every lister on the market — this one by far gives me the most control.

No screenshot-and-retype. No alt-tabbing. No manual photo wrangling. Avarus does the busywork — you hit Publish.
Browse your dealership's listings on any of the three sources. A "Post to Facebook" button appears on every car card.
Avarus scrapes the spec, downloads up to 20 photos, writes an AI description, and opens the Marketplace form fully filled in a new tab.
Glance over the pre-filled form, tweak the description if you like, and click Publish. The whole car, live, in about a minute.
One extension reads three sources, fills every field, and keeps your listings honest. Built with dealers who post every day.
A "Post to Facebook" button on every AutoTrader, CarGurus & Cars.com card. Click it — the Marketplace form opens fully filled in a new tab.
Compelling copy generated from the vehicle spec, tuned to your voice — Casual, Friendly, Professional, or Spanish. Fully editable before you post.
Up to 20 photos downloaded from the source and dropped straight into the Marketplace upload field — in original order.
Already-posted cars get a colour-coded badge on your inventory pages — green for recent, amber after 3 days. Never re-list the same car.
Queue multiple cars and run them back-to-back. Avarus paces each post, prompts you to review, and advances automatically.
Detects specialty builds — Shelby, Roush, Hennessey, Rocky Ridge — from the dealer description and writes the correct model automatically.
Checks every posted car against its source — flags price changes, mileage updates, and delisted vehicles. Keeps you FTC CARS Rule compliant.
Pick posting speed, mileage units, and description voice. Match your workflow and your local market.

In development
I've used all the listers on the market and this one by far gives me the most control.
The AI descriptions actually sound like me. I edit maybe one line before I hit publish.
Posted our whole weekend inventory on a Friday afternoon before anyone else left the lot.
The extension fills in every field and uploads your photos, but you always review the completed form before it goes live — you click Publish. Auto-publish is an optional setting for experienced users, off by default.
The extension mimics normal human browsing — it opens real tabs in your browser, uses your logged-in account, and adds randomized delays between every action. No bots, headless browsers, or API workarounds. It looks identical to manual posting.
No. You just need to be logged into Facebook in Chrome — the same personal account you already use. Avarus posts to Marketplace under your account exactly as if you typed everything yourself.
Photos are downloaded from the source listing directly to your computer and uploaded to Facebook from there. They never touch our servers, and original order is always preserved.
The audit checks every posted car against its current source listing. If a price changed or a vehicle was removed after you posted, it flags it so you can update Facebook before a buyer spots the mismatch — keeping you FTC CARS Rule compliant. It's a Pro feature.
After 10 free postings your account pauses — your audit log, post history, and settings are saved. Subscribe any time to pick up exactly where you left off.
Yes. It's a Chrome extension — it works on any computer running Google Chrome, regardless of operating system. It's a desktop tool.
Avarus is in active development. Here's what's in the pipeline — and what just shipped.
Desktop notification the moment an audit detects a price change or a removed vehicle.
Warns you before opening a listing if the same VIN is already in your audit log. No more double-posts.
Posted a car outside Avarus? Mark it manually so the audit log and duplicate detection still track it.
One-click CSV export of your full posting and audit history — useful for FTC CARS Rule compliance.
Post straight from CarGurus and Cars.com inventory too — the same one-click flow as AutoTrader.
After an audit, hit one button and Avarus opens each out-of-sync listing and updates the price and details for you.
Get notified when a source listing drops below what you posted — update before a buyer spots the mismatch.
Set a weekly ad budget and let Avarus allocate spend across your active Marketplace listings based on performance.
