Spec score 7.4 #24 of 31 in Digital Product Selling Platforms

What it is

Sellix is a commerce platform for digital and physical goods, offering public shops, hosted checkout, and a management dashboard. Checkout is crypto-only: buyers select supported assets while displayed fiat prices are converted during payment, and cards are unavailable. Products can include license keys, file downloads, accounts, Discord roles and invites, physical goods, subscriptions, and custom payloads. Confirmed payments can trigger keys, signed download URLs, webhook payloads, or physical-order status. The REST API and signed webhooks support custom integrations, with BlockPN settlement and Discord delivery documented. API keys use granular permissions, expire within at most 90 days, and can be revoked. Webhooks use HMAC-SHA256 and retry up to six times. The plan costs nothing with no subscription, take-rate, or expiry. Sellix supports unlimited shops, products, orders, and customers, plus custom domains, teams, roles, and 2FA.
