MarketplaceBuddy | Launch Your Own Digital Products Marketplace

Run your own CodeCanyon. MarketplaceBuddy is a complete multi-vendor marketplace for templates, UI kits, plugins and scripts: authors apply, submit products, get reviewed and get paid, while buyers browse, purchase and download. You host it, you set the commission, you keep the platform.MarketplaceBuddy is one Next.js application and one PostgreSQL database. There is no second service to run, and we take no revenue share and charge no recurring fee for the software. docker compose up and you have a marketplace. It is self-hosted, so the server, domain, email and any payment gateway you connect are yours to arrange and pay for — see What this costs to run below.MarketplaceBuddy  demo is read-only. Every screen opens and nothing you change is saved, so sign in as anyone and click anything. The sign-in page has one-click buttons for the accounts below; you can also type them.Buying works. Checkout runs on a demo gateway that takes no money and issues a real licence, a real receipt and a real download, so you can follow a purchase from cart to file. Outbound email is trapped rather than sent. The catalogue, the sales figures, the reviews and the authors are sample data.What this costs to run (please read before buying)This purchase covers the software only. MarketplaceBuddy is self-hosted, so you provide and pay for everything it runs on and connects to. None of the following is included in the purchase price, and none of it is billed by us.Server / VPS hosting — required. Roughly $12–24 per month is enough to launch.A domain name — required. Roughly $10–15 a year from your registrar.An SMTP email service (Postmark, Resend, Mailgun, Amazon SES, Gmail and similar) — required, because verification links, receipts and password resets all send mail. Free tiers exist; paid plans typically start around $15 a month.Payment gateways — Stripe, PayPal, Razorpay — optional. Each charges its own per-transaction fees, set by them and billed by them, under their terms and subject to their country availability. You will need an approved merchant account with whichever you choose.S3-compatible storage — Amazon S3, Cloudflare R2, MinIO — optional, and billed by usage.Redis and Meilisearch — optional accelerators only, and only if you choose to run them.Two of those deserve to be precise, because they are the ones people assume are mandatory. You do not need a payment gateway to launch: a bank-transfer gateway is built in and takes orders with no third-party account at all. You do not need S3: storage defaults to the server’s own disk and works fully that way. Either can be added later without reinstalling.Taxes and compliance obligations in your jurisdiction, any company or merchant account you need, and any custom development you commission are likewise yours.Why this oneMoney is a ledger, not a number. Author balances are never stored and edited. Every sale, refund, adjustment and payout is an immutable row, and balances are derived from them. Refunds are compensating entries, never edits. The database itself rejects updates and deletes on those tables, so the books cannot be quietly rewritten — by a bug, or by anyone with database access.Payments that already work. Stripe, PayPal, Razorpay and manual bank transfer. Enable any combination, let the buyer choose at checkout, and optionally preselect a gateway by country. All four have been driven end to end against live sandbox accounts, not just unit tested.One completion path. Card, wallet or bank transfer, every order is fulfilled by the same code under the same row lock, with the same licences, ledger entries, receipts and replay protection. There is no second-best path to reason about.Tested where it counts. 534 unit tests and 88 browser tests, with the money paths — checkout, refund, payout, download — covered end to end in a real browser against a real database.Runs as one vendor or a hundred. A single setting switches the whole product between multi-vendor and single-vendor. In single-vendor mode every author-facing surface disappears and the code behind it short-circuits, so you can sell your own catalogue today and open it to other authors later without migrating anything.
