Sellix

Sellix suits merchants selling digital or physical goods whose customers can pay with cryptocurrency and who want a hosted shop with automated fulfilment. Its broad catalog and API are compelling at no monthly cost, but crypto-only checkout rules it out for stores that need card payments.

Overview

Sellix combines public shops, hosted checkout, and a management dashboard for digital and physical commerce. Merchants can sell files, license keys, accounts, subscriptions, physical goods, Discord roles and invites, or custom dynamic payloads. The range makes it more adaptable than a storefront focused only on downloadable files, while crypto-only checkout narrows the customer base it can serve.

Buyers pay using supported crypto assets; prices can be displayed in fiat and converted at checkout. Card payments are unavailable by design. BlockPN handles checkout and settlement, sending funds to the merchant’s BlockPN wallet; Sellix sees transaction references but does not hold or control funds. Signup requires an email and password, without KYC or bank-account verification.

Key features

After payment confirmation, automated delivery can issue license keys, signed download URLs, or webhook payloads. For physical orders, it can provide fulfilment status. Discord roles and invites can be delivered through dynamic webhooks, while the REST API and webhooks support custom integrations. Sellix also documents a BlockPN checkout and settlement integration.

The REST API uses bearer tokens with granular permissions. Keys can be revoked independently and expire within 90 days at most. Webhooks use HMAC-SHA256 signatures and retry up to six times with the same event ID, body, and signature. These controls give merchants useful ways to manage integration access and verify event delivery.

Sellix states that two-factor authentication is available for every account and team member. Shop data is stored in the EU or UK, credentials are encrypted at rest, and data is encrypted in transit. These protections are relevant for merchants managing staff access and customer orders through the platform.

Pricing

The Sellix plan costs free, billed $0 / month, with no subscription, take-rate, or expiry. It includes unlimited shops, products, orders, and customers; digital, physical, subscription, and license-key products; a custom domain and whitelabel; REST API and signed webhooks; and teams, roles, and two-factor authentication.

There is no paid tier to unlock greater shop, product, order, or team-member capacity: Sellix says those categories are uncapped. API keys have configurable limits from 10 to 600 requests per minute, with a default of 60, so integrations with heavier traffic may need configuration. The main trade-off is not a lower plan’s missing features but the crypto-only payment model.

Platforms

Sellix is available on the web and through an API. That pairing suits merchants who want a hosted shop or need to connect their own workflows; it does not offer a listed mobile platform.

Who it's for

Sellix is a strong fit for merchants with crypto-paying customers who sell a mix of digital products, subscriptions, or physical goods and value automated delivery, custom domains, and API-based integrations without a monthly bill. It is a poor fit for businesses that rely on card payments, or for merchants who need a support inbox or chat queue: Sellix directs users to public documentation, a status page, and an abuse or legal report form instead.

Pros and cons

• Pros: The $0 plan has no subscription, take-rate, or expiry, and includes custom domains, whitelabel, API access, signed webhooks, and team roles.
• Pros: The catalog spans digital, subscription, and physical goods, with automated delivery options suited to different product types.
• Pros: Granular API keys, signed webhooks, and two-factor authentication provide concrete security controls for integrations and account access.
• Cons: Crypto is the only payment option, excluding customers who need to pay by card.
• Cons: There is no support inbox or chat queue, which may leave merchants dependent on documentation and the status page when they need help.

Alternatives

For another digital-product storefront, browse Digital Product Selling Platforms. Bandcamp is worth considering for a direct-to-fan store with messaging, automatic fan notifications, listening parties, and live streaming; its free Artist account is available free of charge.

Blink offers an API and web platform with all features unlocked on its Starter plan at no cost, but charges 5% + 50¢ per transaction. Its Scale plan has custom pricing with lower revenue-based rates, priority support, and custom feature requests. Consider it when those paid-plan options matter more than Sellix’s no-take-rate pricing.

Lemon Squeezy has no monthly ecommerce charge on its free Ecommerce plan, with transaction fees when sales are generated. PayLoadz is another option with free plans and a free trial. Robora offers a free Starter plan with a $10 pricing limit and a 6% + 30¢ processing fee, or an unlimited plan at $15 a month with a 2.9% + 3¢ fee. These alternatives may suit readers comparing payment-fee structures or a pricing cap.

SellApp has a free Standard plan with fees calculated per sale and billed the following month, and supports any payment method; it is a better direction for merchants who need payment flexibility. Sellwire has a free plan limited to one file, with paid Solo and Agency plans for higher file allowances. Shoppy has a free plan with unlimited orders and products and a 5% fee on crypto, alongside free PayPal; it may be relevant to merchants weighing those payment options.

Verdict

Choose Sellix if you want a no-monthly-cost shop for varied goods, automated delivery, and API integrations, and your customers can pay in crypto. Its uncapped core resources and included custom domain make it a practical option for merchants who do not need conventional card checkout. Look elsewhere if card payments are essential or you expect a support inbox or chat queue.
