Sellup vs Shopify: Best Platform for Digital Products

Update (August 2026): Billgang and Antistock have been seized — both domains now point to FBI seizure nameservers, and Sellpass is offline as well. Sellers displaced by the shutdown can read what happened and what to do now.

Sellup.io vs Sellpass — Which Platform Should You Choose in 2026?

Sellpass was one of the leading platforms for selling digital products, known for its clean interface, strong crypto payment support, and active community of digital sellers. But in late 2025, everything changed. Sellpass announced a rebrand to Antistock, paused all development on the existing platform, and began pushing sellers to migrate to an entirely new system.

For sellers who built their business on Sellpass, this created serious uncertainty. At the time, the choice was: migrate to Antistock, wait and see, or find a more stable alternative. That question has since been answered — Antistock was seized in August 2026 and Sellpass is offline. This comparison breaks down how Sellup.io stacks up against what Sellpass offered across every dimension that matters.

Platform Stability

The single biggest concern with Sellpass was stability. Development had been paused on the existing Sellpass platform, and sellers were asked to migrate to Antistock — a completely different platform with its own pricing, features, and infrastructure. That story has now ended: Sellpass is offline, and Antistock's domain points to FBI seizure nameservers.

Sellup.io is actively developed with weekly updates. The platform has shipped 20 version releases in the past 6 months covering security hardening, analytics improvements, SEO tools, affiliate programs, premium restructuring, Discord integration, and more. The public changelog and bug fixes page provide full transparency into what is being built and fixed.

Transaction Fees

Sellpass charged 3.5-4% transaction fees on the free tier. The $19/mo Business plan removed these fees. Sellup.io charges 0% transaction fees on its single €14.99/month Premium plan, with everything included. On $5,000 in monthly sales, a Sellpass free user lost $175-200 to transaction fees. A Sellup.io user keeps all of it.

Payment Gateways

Sellpass supported Stripe, PayPal, and select cryptocurrency options, with some gateways limited to paid plans. Sellup.io offers 11 payment gateways: Stripe, PayPal, Coinbase Commerce, NOWPayments, Binance Pay, BTCPay Server, Skrill, Square, Perfect Money, Amazon Pay, and Paysafecard. No gateway is locked behind a paywall.

Store Features

Sellpass offered a customizable storefront with basic templates. Sellup.io provides 8 store templates with 18 color settings, announcement bars, hero sections, social proof popups, and particle effects. Beyond aesthetics, Sellup.io includes features Sellpass never had: an affiliate program, flash sales with countdown timers, gift cards, customer tiers, abandoned cart recovery, and a built-in blog system.

Migration

Sellup.io supports CSV import for Sellpass exports, with support-assisted migration to bring over your products, categories, orders, reviews, and coupons. If you exported your Sellpass data before the platform went offline, you can move your entire store to Sellup.io.

Pricing Comparison

Sellpass charged $19/mo for the Business plan that removed transaction fees. Sellup.io costs €14.99/month with everything included — custom domains, affiliates, flash sales — and 0% transaction fees, comparable to Sellpass Business while offering significantly more features and zero platform fees.

The Verdict

If you value platform stability, lower costs, and a broader feature set, Sellup.io is the clear choice. Sellpass is offline and Antistock has been seized, so neither is an option for sellers who need a reliable platform today. Sellup.io is actively developed, charges no transaction fees, and supports CSV import for Sellpass exports.

Community and Ecosystem

Sellpass built a strong community of digital sellers, many of whom were active in Discord servers and forums. The Antistock rebrand fragmented this community, with sellers scattering across multiple platforms. With Antistock now seized and Sellpass offline, that community has dispersed for good.

Sellup.io has an active Discord server with live platform monitoring through the Sellup Live bot. New stores appear in real-time, platform updates are posted in the changelog channel, and support is available through a ticket system. The community is growing as more sellers discover the platform through comparison pages, blog posts, and forum recommendations.

Developer Features

Sellpass offered a developer API that was popular among sellers who automated their workflows — auto-restocking, custom checkout experiences, and integration with external tools. With Sellpass offline and Antistock seized, that API is permanently dead.

Sellup.io offers a full REST API with Bearer token authentication, comprehensive endpoint documentation, and a webhook system that fires on order events, review submissions, and other platform activities. The API is actively maintained and documented as a Premium feature.

Product Delivery

Sellpass handled serial key delivery and file downloads well, with instant delivery after payment confirmation. Sellup.io matches this with instant serial key delivery, secure file downloads with tokenized links that expire after 7 days and 5 downloads, and service deliverables for custom fulfillment. Product variants with independent pricing and stock tracking add flexibility that Sellpass did not offer.

Long-Term Viability

This is the critical question for any platform decision. Sellpass has demonstrated that platform transitions happen — and they can be disruptive. The rebrand to Antistock meant sellers had to rebuild their stores, reconfigure their payment settings, and potentially lose historical data during migration — and the seizure of Antistock in August 2026 ended the platform entirely.

Sellup.io is committed to stability. The platform has shipped 20 version updates in 6 months, maintains a public changelog, and supports one-click import from 5 platforms plus CSV import for Billgang, Antistock, and Sellix exports — making it easy to join and easy to bring your data if you ever need to leave. The combination of active development, transparent communication, and fair pricing makes it a reliable long-term choice for digital sellers.
