Choosing the right link in bio tool for selling comes down to three questions: what you're actually selling, how much you're already making, and whether you'd rather pay a percentage fee or a flat subscription.

Start with what you're actually selling

Not every platform handles every product type the same way. If you're selling a file — a template, preset pack, or ebook — look for a straightforward digital product flow like this one: digital product guide. If it's a live session, you need real event handling — virtual, in-person, or hybrid: event ticket guide. Recurring income means checking how memberships and bookings actually work day to day, not just at checkout.

Free plan vs. paid subscription: the real tradeoff

Every platform in this space picks one of two models: a free plan with a percentage fee on each sale, or a flat monthly subscription with no fee. Neither is universally better — it depends on your volume. At low sales volume, a free-plan fee costs you almost nothing in absolute dollars, so a subscription is pure downside. Once you're consistently selling a few hundred dollars a month, the math flips and a flat fee can beat a percentage. The full breakdown of how this plays out across platforms is here: the numbers, and the same math shows up again comparing Linktree's tiers.

Constants vs the big three, at a glance

Against Stan Store, the difference is subscription versus fee — Stan charges nothing per sale but starts at $29/month with no free tier: the Stan Store comparison. Against Linktree, it's about the free-plan fee — 12% versus 6% on the same $0 tier: the Linktree comparison. Against Beacons, it's a leaner storefront at a lower free-tier fee, without the bundled media kit and email tools: the Beacons comparison.

A simple decision framework

If you haven't made a sale yet and don't want a subscription, start on whichever free plan charges the lowest fee for what you're selling — that's Constants at 6% versus Beacons at 9% or Linktree at 12%. If you're already making a consistent few hundred dollars a month, run the actual numbers on a flat-fee subscription before assuming it's cheaper; sometimes it is, sometimes the percentage still wins. If you need a bundled media kit and email marketing tool alongside your storefront, that's a real feature gap worth paying for on some platforms. And if what you're selling doesn't fit neatly into a digital download or a one-time booking — recurring memberships, live events, ongoing coaching — check that the platform actually supports it natively before you build your page around it.

The bottom line

There's no single right answer here, only a right answer for your current sales volume and what you're selling. Full pricing details for every plan are at pricing, and the comparisons above cover the honest tradeoffs against the three platforms most creators consider first.
