Overview

Cross-post Facebook Marketplace listings to Nextdoor and Craigslist. Sidebar UI with cloud sync via Crosslyst.com sign-in.

Crosslyst turns one for sale listing into listings on Facebook Marketplace, NextDoor and Craigslist — without retyping a word or re-uploading a single photo. Selling one item on three marketplaces normally means filling out the same form three times: same title, same description, same price, same twelve photos, three different category pickers. Crosslyst does that part for you. Open the sidebar, pick the item, choose where it goes, and watch the fields fill themselves in. WHAT IT DOES • Create a listing for Facebook Marketplace — title, description, price, condition, category, location, and every photo and post it or copy an existing listing. • Fills the posting forms on Nextdoor and Craigslist automatically, including the category pickers, location and region selectors, and the photo uploads. • Keeps one master copy of each item. Edit it once and push the update to every marketplace you've posted it to. • Tracks where each item is live and when it was posted, so you always know what's out there. • Reminds you what to do next — check engagement, refresh a stale post, drop the price, or take it down when it sells. • Emails you a short daily digest of the tasks that are actually due. WHY PEOPLE INSTALL IT • It saves the boring part. A three-marketplace post drops from ~15 minutes of copy-paste to a couple of minutes. • Photos come along for the ride. No downloading images to your desktop just to upload them again. • Fewer takedowns. Crosslyst screens drafts against Facebook Commerce and Nextdoor community policies before you post, and warns you when a new listing looks like a near-duplicate of one you already have live. • Nothing goes stale. Scheduling and repost reminders are engagement-aware, so you refresh listings that need it instead of spamming feeds. • It's free. No ads. No upsell wall. HOW IT WORKS 1. Install Crosslyst and pin it to your toolbar. 2. Sign in with your free Crosslyst.com account to sync your items across devices. 3. Open a Facebook Marketplace listing (or create an item in Crosslyst) and capture it or create a new listing in Crosslyst 4. Click Facebook, Nextdoor or Craigslist in the sidebar — Crosslyst opens the posting flow and fills it in. You review and hit publish. PRIVACY Crosslyst does not sell your data, does not show ads, and does not track your browsing. It reads pages only on Facebook Marketplace, Nextdoor, and Craigslist, and only to read or fill listing forms. Your listing content is stored in your own Crosslyst account so it can sync between your devices, and nothing is shared with third parties. Full policy: https://crosslyst.com/privacy Crosslyst is an independent tool and is not affiliated with, endorsed by, or sponsored by Facebook/Meta, Nextdoor, or Craigslist.
