Tools for selling from a page you own
Qart is a set of tools for people, shops and local networks who want to take money on their own terms. A buy button in plain HTML, pay links, receipts with permanent addresses, books, and a counter for selling in person. Bitcoin (BSV) goes straight to your address. At the counter and for tickets, cards go through your own Stripe account.
Inventory that travels with you
Keep track of what you own, list what you want to sell, and move between personal and merchant contexts without switching products.
Payments that settle directly
Qart is built around bitcoin-native checkout, low-fee transfers, and receipts that stay linked to the transaction.
Identity that stays yours
Handles, contacts, follows, and order history are part of the product, not something rented from a third-party platform.
What Qart combines
Most commerce stacks fragment the experience into storefronts, wallets, loyalty software, reporting tools, and API gateways. Qart keeps those layers in one product so the flows stay coherent.
Marketplace
List items, browse other sellers, check out, and manage orders.
Wallet
Manage balances, addresses, transactions, and direct payments.
Merchant tooling
Run POS, loyalty, prepaid cards, and reports for real shops.
Programmable commerce
Use the 402 paygate, checkout APIs, and keypair auth for new flows.
In one account
Items and listings
Personal inventory and active market listings live side by side.
Wallet and transfers
Keep balances, request payments, and move funds directly.
Merchant operations
Switch into POS, orders, and reporting when you are running a shop.
Identity and trust
Handles, follows, reviews, and receipts reinforce the network over time.
Principles
Source you can read
The code is public and you can host it yourself. It is under the Business Source License today and becomes Apache 2.0 on April 8, 2030.
Data ownership
Your contacts, items, and transaction history should not be trapped in someone else's silo.
Peer-to-peer default
Payment, messaging, and exchange should work directly between participants whenever possible.
Programmable commerce
Receipts, loyalty, and APIs should be first-class product features, not bolt-ons.
