cartt.io vs Gumroad: Comparison for Digital Sellers (2026)

If you sell digital products, you've probably hit the Gumroad fee math at some point. 10% + $0.50 per transaction on direct sales, 30% if your sale comes through Gumroad's Discover marketplace. For a creator doing $5,000/month, that's $550–$1,500 going to Gumroad before you see a dollar.

That's the conversation that drives most cartt.io comparisons. So let's have the honest version of it.

This is a head-to-head: cartt.io vs Gumroad, feature-by-feature, money-by-money. Where Gumroad wins, we'll say so. Where cartt.io wins, we'll show the math.

The fee math, plain

Both platforms add their cut on top of payment processing. Here's what a $50 sale actually costs:

Gumroad direct sale

• Gumroad fee: $5.00 (10%) + $0.50 = $5.50
• Stripe processing (estimated, paid by Gumroad): ~$1.75
• You receive: ~$42.75

cartt.io

• cartt.io platform fee: $0
• Stripe processing (your account): $1.75
• You receive: ~$48.25

That's a $5.50 difference per $50 sale, or ~11% more revenue per transaction.

Over 100 sales/month, that's $550 you keep instead of send to Gumroad. Over a year of moderate sales, the difference funds a part-time contractor.

If your sales come through Gumroad's Discover marketplace (the search/category browse experience), the cut jumps to 30%. The same $50 sale nets you ~$33.25. That's the trade for marketplace discovery — and it's the trade most cartt.io users say they want out of.

Where Gumroad wins

This isn't a hit piece. Gumroad does several things cartt.io doesn't:

Discover marketplace traffic. If you're a brand-new creator with no audience, Gumroad's Discover surface can put your product in front of buyers who aren't searching for you specifically. cartt.io has no equivalent — you bring your own traffic.

Affiliate program built-in. Gumroad lets you set up affiliate splits with a few clicks. cartt.io doesn't ship a native affiliate system. Most creators don't use affiliates, but if you do, this matters.

Single-platform simplicity for beginners. Gumroad is one signup, no Stripe account, no provider setup. cartt.io requires a Stripe Connect OAuth (still under 5 minutes, but it's one more step).

Ratings and reviews. Gumroad shows aggregate buyer ratings on product pages. cartt.io leaves social proof to your own content (testimonials, UGC galleries).

If those four things matter more than fees, Gumroad's the better fit. Most creators we hear from realize after their first few thousand in sales that fees outpace marketplace traffic value — but it's a real tradeoff.

Where cartt.io wins

0% platform fee. As above. The single biggest reason creators switch.

Your Stripe account. Payments flow into your account directly. You see deposits in your bank without an intermediary. Refunds, chargebacks, and dispute responses happen in the Stripe dashboard you already know. If you ever leave cartt.io, your payment history goes with you because it was always yours.

Page design. Gumroad product pages are template-locked. They look like Gumroad. cartt.io ships with five visual templates (Minimal, Modern, Bold, Classic, Elegant) plus a visual editor — your checkout looks like your brand, not a marketplace listing.

Built-in conversion tools. Countdown timers, urgency badges, social-proof bars, recently-viewed pop-ups, UGC galleries, order bumps, post-purchase upsells. On Gumroad, most of those require either being in their higher tier or just don't exist. On cartt.io, they ship in the box.

Physical products with real shipping. Gumroad supports physical products but the shipping experience is basic. cartt.io supports 25-country shipping, up to 5 shipping rates per page, automatic tax calculation via Stripe, inventory tracking, and order-status tracking pages with email notifications.

Custom domains. Pro and Business plans connect your own domain with automatic SSL. Gumroad keeps you on gumroad.com/yourname or their custom-domain feature on higher tiers.

When to pick each

Pick Gumroad if:

• You have zero existing audience and want marketplace discovery
• Native affiliate splits are a must
• You're testing whether your product has demand and don't want to commit to a custom checkout

Pick cartt.io if:

• You have any audience and want to keep more revenue
• You want your checkout to look like your brand, not a marketplace listing
• You want built-in conversion tools (timers, urgency, social proof, upsells) without paying for apps
• You sell physical products and need real shipping
• You want to own your customer relationship via Stripe

What about migrating?

Migration is simpler than most creators expect. There's no payment migration because payments live in your Stripe account, not in cartt.io's. The steps:

1. Create your cartt.io page (~5 minutes)
2. Add your products
3. Connect your Stripe via OAuth (~30 seconds)
4. Update the links you share — newsletters, social bios, ad campaigns

Past sales records stay in Gumroad. Future sales flow to Stripe. That's it.

The honest summary

If you sell digital products and have any audience, the fee math eventually wins. The Gumroad cut on every sale stops being worth marketplace traffic that probably isn't bringing buyers.

If you're brand new and need marketplace discovery to validate demand, Gumroad's Discover tier has value — but be aware of the 30% number on those sales.
