A marketplace for people you trust

Your next find starts with someone you already know.

Main Quest Market is the place to buy, sell, and trade inside the circles that already trust each other — your neighborhood, your co-op, your college friend group. No strangers, no public listings, no doom-scrolling through a stranger's garage sale.

Free for every collection. iOS, Android, and web.

How it works

Three steps, zero strangers.

  1. 01

    Start a collection

    Create a collection for whatever you're organizing — a moving sale, a gear closet, a whole neighborhood swap.

  2. 02

    Invite your people

    Send invites to the folks you want in it. They follow your collection; nobody outside it ever sees a thing.

  3. 03

    List, chat, and claim

    Post items, message the group directly, and comment on listings — all in one place, no separate group chat required.

Features

Everything a trusted marketplace needs. Nothing it doesn't.

Collections & listings

Organize what you're selling or trading into collections — one for the garage, one for the co-op, one for the group camping trip.

Direct messages

Talk through the details without leaving the app. Every conversation stays tied to the people in your collections.

Comments, per collection

Ask questions right on a listing. Owners can turn comments off for any collection, any time.

Real-time notifications

New message, new listing, new comment — you'll know the moment it happens, not the next time you happen to check.

iOS, Android, and web

A native app on your phone, a full experience in your browser. Your collections stay in sync everywhere.

You decide who's in

Every collection is invite-only by default. Followers can browse and message; only owners can list.

Not another public marketplace

Built for the people you'd actually hand your keys to.

Main Quest Market isn't trying to be the biggest marketplace out there — it's trying to be the one you don't think twice about using. Every collection starts private and stays that way unless you invite someone in.

“We run our tool-share for the whole street through one collection. Nobody has to text nine people to ask who has the ladder anymore.”
Marisol P. Organizes a neighborhood tool-share
“Our co-op used to coordinate bulk buys over a group chat that nobody could ever scroll back through. Now it's just a collection with listings.”

“I sold my old climbing gear to three different friend groups without a single stranger showing up at my door.”
