The best Sellix alternatives in 2026: five platforms for digital goods with crypto checkout

A seller with a few hundred game keys and software licenses in stock wakes up to find their store unreachable, their checkout gone and their customers asking where their orders are. That is roughly what happened to many Sellix merchants in early 2025, and it is why Sellix alternatives are still one of the most searched topics among digital sellers who take crypto.

This guide compares five platforms that sellers of digital goods, game keys and software licenses move to: PapelShip, Sell.app, SellAuth, Shoppy and Whop. It covers what each one charges, where your crypto goes before it reaches you, how keys are delivered, and what to check before you move a catalog. Competitor facts come from each company's own pricing and documentation pages as of October 2026.

What are the best Sellix alternatives?

The five platforms most often compared as a Sellix replacement are PapelShip, Sell.app, SellAuth, Shoppy and Whop. Sell.app, SellAuth and Shoppy follow the same pattern Sellix did: a hosted storefront, automatic delivery of serials and files, and crypto alongside cards and PayPal. Whop takes a different approach built around memberships and access. PapelShip combines a storefront and crypto checkout with software licensing, which matters if what you sell is your own software rather than resold keys.

Some context on why the search exists at all. In late January 2025 the sellix.io domains were taken offline as part of an international law enforcement operation coordinated by Europol, and the service has not returned. For legitimate merchants this meant an abrupt loss of their storefront, order history and checkout, with no export window. That experience should shape how you pick the next platform: you want one with a clear business model, documented payment flows and as little of your money held by a third party as possible.

What to look for in a Sellix replacement

Every platform on this list can sell a file or a serial and accept crypto. That is the baseline. The differences that matter for a digital goods business are less visible on a landing page, so write these down before you compare.

• –Fees. Is there a percentage on every sale, a monthly plan that removes it, or both? Remember that card processor fees are almost always charged on top, by Stripe or whichever gateway you connect.
• –Crypto custody. Does a customer's payment go straight to your own wallet, into a wallet the platform generates and then forwards, or into a balance you withdraw later? The fewer hops, the less you depend on the platform staying online. Our guide to custodial and non-custodial crypto payments explains the difference in detail.
• –Payouts. How quickly do card and crypto funds reach you, and what does each payout cost? A low checkout fee can be offset by a high payout fee.
• –Account holds. Can the platform freeze a balance it holds? If it never holds your funds, there is nothing to freeze.
• –License delivery. Serial stock that is handed out one key per order is standard. Keys generated on demand, bound to a device and checked by your software at runtime are a different product, and only some platforms offer them.
• –Fraud tools. Digital goods are a favourite target for stolen cards. Look for blacklists by email, IP and country, proxy detection and rules you can tune. See fraud prevention for digital goods for what a good setup looks like.

Five Sellix alternatives at a glance

The table summarises the published fee model and crypto handling for each platform. Card processor fees from Stripe, PayPal and similar gateways apply on top of the platform fees shown, except on Whop, which is itself the processor.

The alternatives in detail

Each platform makes a different trade between fees, control and scope. Read these for what each one is designed to do well.

PapelShip

PapelShip is a digital commerce and software protection platform. The storefront builder comes with themes and a visual editor, a custom domain with free SSL, payment links and an embeddable checkout. Crypto is paid wallet to wallet straight to the seller's own wallet, with no balance held in between, and cards run through gateways such as Stripe and PayTR, with bank transfer and gift cards as extra options. License keys and files are delivered instantly at checkout, and stores get coupons, subscriptions, staff accounts with role permissions, customer blacklists, support tickets and reseller programs. What sets it apart is qPapel Auth: if you sell your own C, C++ or C# software, keys can be HWID-locked and checked at runtime instead of only handed out. The Free plan has no monthly fee and charges 1.69% on crypto and 1.00% on cards; PapelShip+ at €14.99 a month removes the store fee entirely. The PapelShip vs Sellix comparison covers the differences in full.

Sell.app

Sell.app is the closest in spirit to the old Sellix model. Its Standard plan has no monthly fee and charges 3% per sale, billed monthly rather than taken from each payment; the Advanced plan at $199.99 a month drops the platform fee to 0%. Payment options include Stripe, Square, PayPal, Cash App, crypto and Paddle for a merchant-of-record setup, and Sell.app states that it does not hold funds and that payouts are instant. For Bitcoin and Litecoin you link an extended public key, so addresses are derived from your own wallet without Sell.app touching your private keys; Ethereum and Solana payments are forwarded to an address you provide. Fraud tools include AI-based filters, a proxy checker and blacklist rules for customers, IPs and countries. It suits sellers who want a mature storefront and are comfortable with a percentage fee until volume justifies the flat plan. See PapelShip vs Sell.app.

SellAuth

SellAuth markets itself on not taking a platform fee and connects an unusually long list of card processors, from Stripe, Square and Mollie to Adyen and Revolut Business, plus PayPal, Cash App and others. Delivery covers serials loaded as stock, downloads, dynamic delivery through your own endpoint, services and physical goods. Crypto works differently from Sell.app: payments land in a wallet SellAuth generates for your shop and are forwarded automatically to your payout address. Bitcoin and Litecoin are on every plan, while Ethereum, Solana and USDT or USDC on those networks need the Business or Scale plan. Blacklisting is granular, by email, IP, Discord ID, country, user agent and ASN. Check SellAuth's site for current plan prices.

Shoppy

Shoppy is one of the older storefronts in this category and keeps things simple. It delivers files, serial numbers, services or items generated through an API, with email delivery, custom email templates and a replacement system. Its pricing page lists a Free plan that charges a fee on crypto orders (the page shows both 4% and 5% in different places) with PayPal free, and a Business plan at $29 a month billed yearly with no processing fees. Payment logos include PayPal, Stripe, Bitcoin, Litecoin and Ethereum. The public site does not explain whether crypto is held in a balance or paid to your wallet, and it does not describe fraud tools, so ask before you rely on either. It suits small catalogs that want a quick setup.

Whop

Whop is a different kind of platform. It is built around memberships, communities and access to digital products, with a discovery marketplace and Discord, Telegram and similar integrations. Whop is itself the payment processor: its fees page lists 2.7% + $0.30 per domestic card transaction, plus 1.5% for international cards and 1% for currency conversion, with optional add-ons for orchestration, billing and tax. Crypto appears there as a payout method at 5% + $1 per payout rather than as a checkout option, and disputes cost $15 each. It suits sellers whose product is ongoing access, such as a paid community or a subscription, more than a stock of keys. See PapelShip vs Whop.

Sell.app vs SellAuth

These two come up together most often, because both are hosted storefronts for digital goods with serial delivery and crypto. The differences are in the fee model and the crypto path.

If you value Bitcoin arriving at addresses from your own wallet and a long-standing pricing page, Sell.app is the more transparent of the two. If you need a specific card processor that few platforms support, or want to avoid a per-sale platform fee at lower volume, SellAuth is worth testing. In both cases, run a real crypto purchase and watch how long forwarding takes before you move customers.

Who each one suits

Whichever you shortlist, compare total cost at your real volume. A 3% platform fee on €2,000 a month is €60; on €40,000 it is €1,200, at which point a flat plan wins easily. Add the card processor's fee, payout fees and any per-dispute charges before you decide. PapelShip pricing lists every fee on one page, and the startup program cuts the fee to 0.10% for six months for companies under €250,000 in annual revenue.

How to migrate from Sellix to a new platform

Because Sellix went offline without an export window, most migrations are really rebuilds. The order below keeps customers from ever hitting a broken checkout.

1. 01

   Rebuild your catalog from your own records

   Gather product names, descriptions, prices and images from your files, old invoices and order emails. Note which products were serials, which were files and which were services.

2. 02

   Reload stock carefully

   Import only keys you know are unsold. If you cannot tell which keys were delivered before the shutdown, retire that batch and issue fresh ones rather than risk sending a used key.

3. 03

   Connect payments and test each one

   Add your crypto wallets and card gateway, then make a real purchase with each method. Confirm the funds reach you and time how long delivery takes.

4. 04

   Set up fraud rules before launch

   Add blacklists for known chargeback emails and IPs, and decide which countries or proxy traffic to review. It is far easier before the first wave of orders.

5. 05

   Point your domain and tell customers

   Connect your custom domain, update links in Discord, social profiles and docs, and email past buyers with the new store address and how to get support.

6. 06

   Keep an export routine

   Schedule a regular export of products, keys and orders so a future outage, on any platform, costs you a day rather than a business.

If you deliver keys for software you build yourself, this is also a good moment to change how those keys work. Handing out static serials means a leaked key works anywhere. Generating keys at checkout and checking them at runtime, with a device binding, means a shared key stops working. How to sell software licenses online walks through that setup, and instant digital delivery covers the store side.

Pick a platform you can leave

The lesson from Sellix is less about any single feature and more about dependence. The best alternative is one whose fees you understand at your volume, whose crypto flow does not keep your money in someone else's wallet, and whose data you can export whenever you want. If the platform disappeared tomorrow, you should lose a storefront, not your revenue or your customer list.

Shortlist two platforms, run a real purchase with every payment method you plan to offer, check how fraud rules behave on a test order, and project fees forward a year. That afternoon of testing is cheap compared with moving stores twice.
