Sellup vs Sellpass: Complete Comparison for 2026

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. Migrate to Antistock? Wait and see? Or find a more stable alternative? Events have since answered that question: Antistock was seized in August 2026 and Sellpass is offline. This comparison breaks down how Sellup.io stacks up against Sellpass across every dimension that matters.

Platform Stability

The single biggest concern with Sellpass was stability — and that concern proved fatal. Development was paused on the existing Sellpass platform, and sellers were pushed to migrate to Antistock, a completely different platform with its own pricing, features, and infrastructure. In August 2026, Antistock was seized — its domain now points to FBI seizure nameservers — and Sellpass went offline as well.

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 costs €14.99/month with everything included and charges 0% transaction fees. 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 one-click API import from Shoppy, SellAuth, Selly, Autobuy, and Sell.app. Because the Sellpass and Antistock APIs are dead, migration from those platforms works via a CSV export file plus support-assisted migration — your products, categories, orders, reviews, and coupons are transferred from your export. If you still have a Sellpass or Antistock data export, the Sellup.io team will help you move your entire store over.

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 — less than 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-based migration from 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 has fragmented this community, with sellers scattering across multiple platforms. The question of whether the community would follow Sellpass to Antistock was settled in August 2026, when Antistock was seized and the remaining community scattered 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. That API is now dead: Antistock was seized in August 2026 and Sellpass is offline.

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 fully documented.

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 forced sellers to rebuild their stores and reconfigure their payment settings, and when Antistock was seized in August 2026, those who had followed lost their storefronts 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.
