Open it in its own tab — the embedded preview does not send the session cookies. The credentials are already filled in there. Behind the login sits the complete admin area with half a year of order history: products, stock, fraud review, warranty cases, reports. Almost everything is clickable, and everything resets hourly.

About this project
Born from a real gap: in early 2025 the largest marketplace for digital goods was seized by the FBI — sellers lost their shop, their customer data and their pending payouts overnight. VAULT is the answer: a complete shop that runs on your own server and belongs to nobody but you. It sells files, licence keys, accounts, services and subscriptions; customers pay by card, PayPal, SEPA or crypto, and the goods deliver themselves the moment payment lands — as a download link, a key from stock, a Discord role or a command to the game server. On top of that, the things you only miss once you are trading: a fraud score for every order, automatic replacement for faulty keys, a ticket system and the German mandatory pages thrown in. A single command installs the lot on a €5 server.
What this project is — and what it is not
A reference project from our own workshop — not an off-the-shelf template. Below is an honest account of what works and what is still missing. If you want to take it over as it stands, that is possible on request.

A guide price based on scope and effort.
What you pay in the end is settled only after the briefing. You get a fixed-price quote before anything starts.
Pakete & Festpreise ansehen What already works
- Sells files, licence keys, accounts, services and subscriptions — including renewals and dunning
- Five payment routes from card and PayPal through SEPA to crypto — payout straight to you
- Delivers automatically: download links, keys from stock, Discord roles or commands to the game server
- Fraud protection per order: risk scoring, VPN detection, nine kinds of blocklist, evidence export for chargebacks
- Warranty with automatic replacement: the system swaps faulty keys by your own rules
- Design and pages freely editable: theme studio, page builder, custom roles and email templates
- Ready for Germany: right of withdrawal, imprint, privacy policy and cookie consent are built in
- One-command install on any €5 server — the HTTPS certificate obtains and renews itself
What is still missing
- Version 0.1.0 — broadly built and automatically tested, but not yet running a real shop in production
- The demo deliberately has no payment providers configured — checkout ends at the payment selection
- Support inbox and theme editor are planned but not built — marked "in progress" in the admin area
- Documentation and changelog are linked in the README but still empty
- Internally the project is still called "projekt-1.0" — the name gives away nothing about what is inside
